China BAK Battery, Inc. and subsidiaries 
Notes to the condensed interim consolidated financial statements 
For the three months ended December 31, 2009 and 2010(Unaudited)

1. Principal Activities, Basis of Presentation and Organization

Principal Activities

China BAK Battery, Inc. (China BAK) is a corporation formed in the State of Nevada on October 4, 1999 as Medina Copy, Inc. The Company changed its name to Medina Coffee, Inc. on October 6, 1999 and subsequently changed its name to China
BAK Battery, Inc. on February 14, 2005. China BAK and its subsidiaries (hereinafter, collectively referred to as the Company) are principally engaged in the manufacture, commercialization and distribution of a wide variety of standard
and customized lithium ion (known as "Li-ion" or "Li-ion cell") rechargeable batteries for use in cellular telephones, as well as various other portable electronic applications, including high-power handset telephones, laptop computers, power tools,
digital cameras, video camcorders, MP3 players, electric bicycles, hybrid/electric motors, and general industrial applications.

The shares of the Company traded in the over-the-counter market through the Over-the-Counter Bulletin Board from 2005 until May 31, 2006, when the Company obtained approval to list its common stock on The NASDAQ Global Market, and trading commenced
that same date under the symbol "CBAK".

Basis of Presentation and Organization

As of December 31, 2010, the Companys subsidiaries consisted of: i) BAK International Limited (BAK International), a wholly owned limited liability company incorporated in Hong Kong on December 29, 2003 as BATCO International
Limited, which changed its name to BAK International Limited on November 3, 2004; ii) Shenzhen BAK Battery Co., Ltd. (Shenzhen BAK), a wholly owned limited liability company established on August 3, 2001 in the Peoples Republic of

1. Principal Activities, Basis of Presentation and Organization (continued)

Basis of Presentation and Organization (continued)

On November 6, 2004, BAK International, a non-operating holding company that had substantially the same shareholders as Shenzhen BAK, entered into a share swap transaction with the shareholders of Shenzhen BAK for the purpose of the subsequent
reverse acquisition of the Company as described below. Pursuant to the terms of the share swap transaction, BAK International acquired all of the outstanding shares of Shenzhen BAK for US$11.5 million in cash, while the shareholders of Shenzhen
BAK acquired substantially all of the outstanding shares of BAK International for US$11.5 million in cash. As a result, Shenzhen BAK became a wholly-owned subsidiary of BAK International. After the share swap transaction was completed, there
were 31,225,642 shares of BAK International stock outstanding, exactly the same as the number of shares of capital stock of Shenzhen BAK that had been outstanding immediately prior to the share swap, and the shareholders of BAK International were
substantially the same as the shareholders of Shenzhen BAK prior to the share swap. Consequently, the share swap transaction between BAK International and the shareholders of Shenzhen BAK was accounted for as a reverse acquisition of Shenzhen BAK
with no adjustment to the historical basis of the assets and liabilities of Shenzhen BAK.

On January 20, 2005, the Company completed a share swap transaction with the shareholders of BAK International. The share swap transaction, also referred to as the reverse acquisition of the Company, was consummated under Nevada law
pursuant to the terms of a Securities Exchange Agreement entered by and among China BAK, BAK International and the shareholders of BAK International on January 20, 2005. Pursuant to the Securities Exchange Agreement, the Company issued 39,826,075
shares of common stock, par value US$0.001 per share, to the shareholders of BAK International (including 31,225,642 shares to the original shareholders and 8,600,433 shares to new investors who had purchased shares in the private placement
described below), representing approximately 97.2% of the Companys post-exchange issued and outstanding common stock, in exchange for 100% of the outstanding capital stock of BAK International.

The share swap transaction has been accounted for as a capital-raising transaction of the Company whereby the historical financial statements and operations of Shenzhen BAK are consolidated using historical carrying amounts. The 1,152,458 shares of
China BAK outstanding prior to the stock exchange transaction were accounted for at the net book value at the time of the transaction, which was a deficit of US$1,672.

Also on January 20, 2005, immediately prior to consummating the share swap transaction, BAK International executed a private placement of its common stock with unrelated investors whereby it issued an aggregate of 8,600,433 shares of common stock
for gross proceeds of US$17,000,000. In conjunction with this financing, Mr. Xiangqian Li, the Chairman and Chief Executive Officer of the Company, agreed to place 2,179,550 shares of the Company's common stock owned by him into an escrow
account pursuant to an Escrow Agreement dated January 20, 2005 (the Escrow Agreement). Pursuant to the Escrow Agreement, 50% of the escrowed shares were to be released to the investors in the private placement if audited net income of
the Company for the fiscal year ended September 30, 2005 was not at least US$12,000,000, and the remaining 50% were to be released to investors in the private placement if audited net income of the Company for the fiscal year ended September 30,
2006 was not at least US$27,000,000. If the audited net income of the Company for the fiscal years ended September 30, 2005 and 2006 reached the above-mentioned targets, the 2,179,550 shares would be released to Mr. Xiangqian Li in the amount of
50% upon reaching the 2005 target and the remaining 50% upon reaching the 2006 target.

Under accounting principles generally accepted in the United States of America (US GAAP), escrow agreements such as the one established by Mr. Xiangqian Li generally constitute compensation if, following attainment of a performance
threshold, shares are returned to a company officer. The Company determined that without consideration of the compensation charge, the performance thresholds for the year ended September 30, 2005 would be achieved. However, after consideration of a
related compensation charge, the Company determined that such thresholds would not have been achieved. The Company also determined that, even without consideration of a compensation charge, the performance thresholds for the year ended September 30,
2006 would not be achieved. No compensation charge was recorded by the Company for the years ended September 30, 2005 and 2006.

1. Principal Activities, Basis of Presentation and Organization (continued)

Basis of Presentation and Organization (continued)

While the 1,089,775 escrow shares relating to the 2005 performance threshold were previously released to Mr. Xiangqian Li, Mr. Xiangqian Li executed a further undertaking on August 21, 2006 to return those shares to the escrow agent for the
distribution to the relevant investors. However, such shares were not returned to the escrow agent, but, pursuant to a Delivery of Make Good Shares, Settlement and Release Agreement between the Company, BAK International and Mr. Li entered into on
October 22, 2007 (the Li Settlement Agreement), such shares were ultimately delivered to the Company as described below. Because the Company failed to satisfy the performance threshold for the fiscal year ended September 30, 2006, the
remaining 1,089,775 escrow shares relating to the fiscal year 2006 performance threshold were released to the relevant investors. As Mr. Li has not retained any of the shares placed into escrow, and as the investors party to the Escrow Agreement are
only shareholders of the Company and do not have and are not expected to have any other relationship to the Company, the Company has not recorded a compensation charge for the years ended September 30, 2005 and 2006.

At the time the escrow shares relating to the 2006 performance threshold were transferred to the investors in fiscal year 2007, the Company should have recognized a credit to donated shares and a debit to additional paid-in capital, both of which
are elements of shareholders equity. This entry is not material because total ordinary shares issued and outstanding, total shareholders equity and total assets do not change; nor is there any impact on income or earnings per share.
Therefore, previously filed consolidated financial statements for the fiscal year ended September 30, 2007 will not be restated. This share transfer has been reflected  by reclassifying the balances of certain items as
of October 1, 2007. The balances of donated shares and additional paid-in capital as of October 1, 2007 were credited and debited by US$7,955,358 respectively.

In November 2007, Mr. Xiangqian Li delivered the 1,089,775 shares related to the 2005 performance threshold to BAK International pursuant to the Li Settlement Agreement; BAK International in turn delivered the shares to the Company. Such shares
(other than those issued to investors pursuant to the 2008 Settlement Agreements, as described below) are now held by the Company. Upon receipt of these shares, the Company and BAK International released all claims and causes of action against Mr.
Xiangqian Li regarding the shares, and Mr. Xiangqian Li released all claims and causes of action against the Company and BAK International regarding the shares. Under the terms of the Li Settlement Agreement, the Company commenced negotiations with
the investors who participated in the Companys January 2005 private placement in order to achieve a complete settlement of BAK Internationals obligations (and the Companys obligations to the extent it has any) under the applicable
agreements with such investors.

Beginning on March 13, 2008, the Company has entered into settlement agreements (the 2008 Settlement Agreements) with certain investors in the January 2005 private placement.

Pursuant to the 2008 Settlement Agreements, the Company and the settling investors have agreed, without any admission of liability, to a settlement and mutual release from all claims relating to the January 2005 private placement, including all
claims relating to the escrow shares related to the 2005 performance threshold that had been placed into escrow by Mr. Xiangqian Li, as well as all claims, including claims for liquidated damages relating to registration rights granted in connection
with the January 2005 private placement. Under the 2008 Settlement Agreement, the Company has made settlement payments to each of the settling investors of the number of shares of the Companys common stock equivalent to 50% of the number of
the escrow shares related to the 2005 performance threshold these investors had claimed; aggregate settlement payments as of December 31, 2010 amounted to 368,745 shares. Share payments to date have been made in reliance upon the exemptions from
registration provided by Section 4(2) and/or other applicable provisions of the Securities Act of 1933, as amended. In accordance with the 2008 Settlement Agreements, the Company filed a registration statement covering the resale of such shares
which was declared effective by the SEC on June 26, 2008.

The Companys condensed interim consolidated financial statements have been prepared in accordance with US GAAP.

1. Principal Activities, Basis of Presentation and Organization (continued)

Basis of Presentation and Organization (continued)

The interim results of operations are not necessarily indicative of the results to be expected for the fiscal year ending September 30, 2011. The Companys consolidated balance sheet as of September 30, 2010 has been taken from the
Companys audited consolidated balance sheet as of that date. All other financial statements contained herein are unaudited and, in the opinion of management, contain all adjustments (consisting only of normal recurring accruals) necessary for
a fair presentation of financial position, results of operations and cash flows for the periods presented. The Companys accounting policies and certain other disclosure are set forth in the notes to the consolidated financial statements
contained in the Companys Annual Report on Form 10-K for the year ended September 30, 2010. These financial statements should be read in conjunction with the Companys audited consolidated financial statements and notes thereto.

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. This basis of accounting differs in certain material respects from that used for the
preparation of the books of account of the Companys principal subsidiaries, which are prepared in accordance with the accounting principles and the relevant financial regulations applicable to enterprises with limited liabilities established
in the PRC, Hong Kong, India, Canada or Germany, the accounting standards used in the places of their domicile. The accompanying condensed interim consolidated financial statements reflect necessary adjustments not recorded in the books of account
of the Company's subsidiaries to present them in conformity with US GAAP.

The Company has a working deficiency and accumulated deficit from net losses
incurred for each of the three years in the fiscal year ended September 30, 2010
and for the three months ended December 31,  2010. These
factors may raise doubts about the Company's ability to continue as a going
concern. The consolidated financial statements do not include any adjustments
that might be necessary if the Company is unable to continue as a going concern.
The Company accordingly has developed a strategic plan to generate a positive
cash flow from operating activities for the fiscal year ending September 30,
2011 (the "FY2011 Turnaround Plan"). Under the FY2011 Turnaround Plan, the
Company will implement cost reductions on both manufacturing costs and operating
expenses to improve margins as well as reduce receivable turnover days through
stronger credit controls.

Recently Issued Accounting Standards

In January 2010, the FASB issued ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements, or ASU 2010-06 that expands the required disclosures about fair value measurements. This guidance
provides for new disclosures requiring the Company to (i) disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers and (ii) present separately
information about purchases, sales, issuances and settlements in the reconciliation of Level 3 fair value measurements. This guidance also provides clarification of existing disclosures requiring the Company to (i) determine each class of assets and
liabilities based on the nature and risks of the investments rather than by major security type and (ii) for each class of assets and liabilities, disclose the valuation techniques and inputs used to measure fair value for both Level 2 and Level 3
fair value measurements. ASU 2010-06 is effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances, and settlements in the roll forward of activity in Level 3
fair value measurements. Those disclosures are effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. Early application is permitted. The adoption of ASU 2010-06 has no material impact on the
Companys financial statements.

In April 2010, the FASB issued ASU 2010-13, Compensation-Stock Compensation (Topic 718) - Effect of Denominating the Exercise Price of a Share-Based Payment Award in the Currency of the Market in Which the Underlying Equity Security Trades - a
consensus of the FASB Emerging Issues Task Force, or ASU 2010-13. ASU 2010-13 provides amendments to Topic 718 to clarify that an employee share-based payment award with an exercise price denominated in the currency of a market in which a
substantial portion of the entity's equity securities trades should not be considered to contain a condition that is not a market, performance, or service condition. Therefore, an entity would not classify such an award as a liability if it
otherwise qualifies as equity. The amendments in this update do not expand the recurring disclosures required by Topic 718. Disclosures currently required under Topic 718 are applicable to a share-based payment award, including the nature and the
term of share-based payment arrangements. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2010. The adoption of ASU 2010-13 has no material impact on the
Companys financial statements.

Organization (continued)

In April 2010, the FASB issued ASU 2010-17, Revenue
RecognitionMilestone Method (Topic 605)Revenue Recognition, or ASU 2010-17.
ASU 2010-17 provides guidance on defining the milestone and determining when the
use of the milestone method of revenue recognition for research or development
transactions is appropriate. It provides criteria for evaluating if the
milestone is substantive and clarifies that a vendor can recognize consideration
that is contingent upon achievement of a milestone as revenue in the period in
which the milestone is achieved, if the milestone meets all the criteria to be
considered substantive. ASU 2010-17 is effective in the Company's first quarter of
fiscal year 2012 and should be applied prospectively. Early adoption is permitted.
The Company is currently evaluating the impact of the adoption of ASU 2010-17 on
its financial statements.

In July 2010, the FASB issued ASU 2010-20, Disclosures about
the Credit Quality of Financing Receivables and the Allowance for Credit Losses
(Topic 310)Receivables, or ASU 2010- 20. ASU 2010-20 enhances the disclosure
requirements about the credit quality and related allowance for credit losses of
financing receivables. ASU 2010-20 is effective for interim and annual reporting
periods beginning on or after December 15, 2010. The adoption of ASU 2010-20 has no
material impact on the Companys financial statements.

The Company grants share options to officers and employees and
restricted shares of common stock to its non-employee directors as rewards for
their services.

Stock Option Plan

In May 2005, the Board of Directors adopted the China BAK
Battery, Inc. 2005 Stock Option Plan (the Plan). The Plan originally
authorized the issuance of up to 4,000,000 shares of the Companys common stock,
pursuant to stock options granted under the Plan, or as grants of restricted
stock. The exercise price of options granted pursuant to the Plan must be at
least equal to the fair market value of the Companys common stock at the date
of the grant. Fair market value is determined at the discretion of the
designated committee on the basis of reported sales prices for the Companys
common stock over a ten business day period ending on the grant date. The Plan
will terminate on May 16, 2055. On July 28, 2008, the Companys stockholders
approved certain amendments to the Plan, including an amendment increasing the
total number of shares available for issuance under the Plan to 8,000,000.

Pursuant to the Plan, the Company granted options to purchase
2,000,000 shares of common stock with an exercise price of US$6.25 per share on
May 16, 2005. In accordance with the vesting provisions of the grants, the
options became vested and exercisable under the following schedule:

|                 | Percentage of  | Initial        
|---------------- | -------------- | ---------------
|Number of Shares | Options Issued | Vesting Date   
|800,000          | 40%            | July 1, 2007   
|600,000          | 30%            | January 1, 2008
|600,000          | 30%            | July 1, 2008   
|2,000,000        | 100%           |                

Subsequent to the grant date, options to purchase 200,000
shares of common stock were forfeited because the optionees terminated their
employment with the Company. In addition, on September 28, 2006, options to
purchase a total of 1,400,000 shares of common stock were cancelled pursuant to
the Termination and Release Agreements signed on that day.

(1) Aggregate intrinsic value represents the value of the
Companys closing stock price on December 31, 2010 (US$1.93) in excess of the
exercise price multiplied by the number of options outstanding or exercisable.

The weighted-average grant-date fair value of options granted
during 2005 was US$3.67 per share. No non-cash share-based compensation expense
was recognized in respect of these share options for the three months ended
December 31, 2009 and 2010.

The fair value of the above option awards was estimated on the
date of grant using the Black-Scholes Option Valuation Model together with the
following assumptions:

|Expected volatility     |  | 59.85%  | 
|----------------------- |  | ------- | 
|Expected dividends      |  | Nil     | 
|Expected life           |  | 6 years | 
|Risk-free interest rate |  | 4.13%   | 

As of December 31, 2010, there were no unrecognized
compensation costs related to non-vested share options.

Pursuant to the Plan, the Company also granted options to
purchase 1,501,500 shares of the Companys common stock with a weighted-average
exercise price of US$3.28 per share on June 25, 2007. In accordance with the
vesting provisions of the grants, the options will become vested and exercisable
during the period from December 31, 2007 to February 9, 2012 according to each
employees respective agreement.

(1) Aggregate intrinsic value represents the value of the
Companys closing stock price on December 31, 2010 (US$1.93) in excess of the
exercise price multiplied by the number of options outstanding or exercisable.

The weighted-average grant-date fair value of options granted
during 2007 was US$2.15 per share. The Company recorded non-cash share-based
compensation expense of US$58,002 and US$24,884 for the three months ended
December 31, 2009 and 2010 respectively, in respect of share options granted on
June 25, 2007, which was allocated to cost of revenues, sales and marketing
expenses, general and administrative expenses and research and development
expenses respectively.

The fair value of the above option awards granted on June 25,
2007 was estimated on the date of grant using the Black-Scholes Option Valuation
Model that uses the following assumptions:

|Expected volatility     | 69.44%      
|----------------------- | ------------
|Expected dividends      | Nil         
|Expected life           | 4 - 10 years

As of December 31, 2010, there were unrecognized compensation
costs of US$48,944 related to the above non-vested share options. These costs
are expected to be recognized over a weighted average period of 0.5 years.

Pursuant to the Plan, the Company also granted options to
purchase 360,000 shares of common stock with an exercise price of US$4.30 per
share on January 28, 2008. In accordance with the vesting provisions of the
grants, the options will become vested and exercisable during the period from
April 28, 2008 to January 28, 2011 according to each employees respective
agreement.

      quarter after the grant date.

10 Share-based Compensation (continued)

As of December 31, 2010, there were unrecognized stock-based compensation costs of US$5,193 associated with these restricted shares granted to non-employee directors. The first and second 25% of the restricted shares were already issued as
fully paid shares of common stock to the Companys three independent directors on August 4, 2010 and October 6, 2010.

Pursuant to the Plan, the Compensation Committee of the Companys Board of Directors recommended and approved the grant of 500,000 restricted shares to Chief Executive Officer, Mr. Xiangqian Li with a fair value of US$2.81 per share on June
22, 2009. In accordance with the vesting schedule of the grant, the restricted shares will vest in twenty equal quarterly installments on the first day of each fiscal quarter beginning on October 1, 2009.

The Company recorded non-cash share-based compensation expense of US$179,682 and of US$91,575 for the three months ended December 31, 2009 and 2010 respectively in respect of the restricted shares granted on June 22, 2009, which was
allocated to general and administrative expenses.

As of December 31, 2010, there were unrecognized stock-based compensation costs of US$499,535 associated with these restricted shares granted to Mr. Xiangqian Li. These costs are expected to be recognized over a weighted-average period of 3.5
years.

As the Company itself is an investment holding company which is not expected to
generate operating profits to realize the tax benefits arising from its net
operating loss carried forward, no income tax benefits were recognized for the stock-based
compensation cost under the Stock Option Plan for the three months ended December 31, 2009 and 2010.

11 Net Loss per Share

The calculation of basic net loss per share is based on the net loss for the three months ended December 31, 2010 attributable to equity shareholders of $3,657,792 (three months ended December 31, 2009: $3,392,327) and the weighted
average number of shares of common stock of 62,895,001 issued and outstanding during the three months ended December 31, 2010 (three months ended December 31, 2009: 61,107,713).

The effects of 4,460,655 shares of stock options, 507,500 shares of restricted stock and 1,447,500 warrants outstanding during the three months ended or as of December 31, 2009 were all anti-dilutive and the effects of 4,586,855 shares of stock
options, 507,500 shares of restricted stock and 1,447,500 warrants outstanding during the three months ended or as of December 31, 2010, also were all anti-dilutive. As such, basic and diluted net loss per share for the three months ended December
31, 2009 and 2010 are the same.

12 Fair Value of Financial Instruments

The fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties. The carrying amounts of financial assets and liabilities, such as cash and cash equivalents, pledged
deposits, trade accounts receivable, other receivables, short-term bank loans, long-term bank loans, accounts and bills payable and other payables, approximate their fair values because of the short maturity of these instruments and market rates of
interest.

13 Commitments and Contingencies(i) Capital Commitments

As of September 30, 2010 and December 31, 2010, the Company had the following contracted capital commitments:

|13 Commitments and Contingencies
      (continued)           
|-------------------------------------------------------------
|                                                             
|                                                             
|For construction of buildings                                
|For purchases of equipment                                   
|                                                             
|(ii) Land Use Rights and Property
      Ownership Certificate

According to the relevant PRC laws and regulations, a land use
rights certificate, along with government approvals for land planning, project
planning and construction, needs to be obtained before construction of a
building is commenced. A property ownership certificate shall be granted by the
government upon application under the condition that the aforementioned
certificate and government approvals have been obtained.

The Company did not obtain the land use right certificate and
approvals for project-planning and construction relating to the premises
occupied by the Company, BAK Industrial Park, before construction of the
buildings was commenced. On July 3, 2009, the Company had obtained the approval
for project-planning and construction from the local government of Shenzhen. As
of December 31, 2010, the Company has obtained the aforementioned land use
rights certificate and government approvals and was in the process of
negotiating with the relevant government for the application and acquisition of
the appropriate property ownership certificate.

Management believes that the Company will ultimately be granted
a property ownership certificate, and that there should be no legal barriers for
the Company to obtain a property ownership certificate for the premises
presently occupied by the Company in BAK Industrial Park. However, in the event
that the Company fails to obtain the property ownership certificate relating to
BAK Industrial Park, there is a risk that the building constructed will need to
be vacated as illegitimate constructions and the Company might be subject to
penalties and fines. However, management believes that this possibility, while
present, is remote.

Pursuant to the land use rights certificate relating to the
Companys Tianjin facility, the Tianjin government had requested that the
Company complete the construction of the Tianjin facility before September 30,
2008. As of December 31, 2010, the Company was in the process of negotiating
with the relevant government bureau for the extension of the completion date. If
the Company fails to obtain the approval for the extension of the completion
date from the relevant government bureau, there is a risk that the land use
rights certificate relating to the Companys Tianjin facility will become
invalid. However, management believes that this possibility, while present, is
remote.

Pursuant to the land use rights certificate that the Company
obtained relating to the Research and Development Test Centre to be constructed
in Shenzhen, the Company must complete at least 25% of the construction of the
Research and Development Test Centre by September 30, 2008. On November 11, 2008
and May 27, 2009, the Company has signed two supplement agreements with Shenzhen
government to increase the dimensions of the Research and Development Test
Centre. According to the supplement agreements, the Company is required to
complete the construction by May 6, 2011. According to the property ownership
and land use rights certificate, such rights may not be pledged without the
approval of the relevant government office. The Company is required to pledge
its property ownership and land use rights certificate in relation to the
Research and Development Test Centre to China Development Bank according to the
loan agreement entered into with it. On April 7, 2010, the pledge of the land
use rights certificate to China Development Bank was approved by the relevant
government bureau. On April 20, 2010, the relevant land use rights certificate
was pledged to China Development Bank.

13 Commitments and Contingencies (continued)

On August 20, 2010, the
Company purchased the new insurance for its manufacturing facilities at BAK
Industrial Park in Shenzhen, China. Under the new insurance policy entered into
with Ping An Property & Casualty Insurance Company of China, Ltd, the
insured amount for our manufacturing facilities at BAK Industrial Park is
RMB550,000,000 (approximately $82.2 million) for the period from August 26, 2010
to March 26, 2012.

On July 2, 2010, the Company purchased insurance for its
manufacturing facilities in Tianjin, China. Under the insurance policy entered
into with Ping An Property & Casualty Insurance Company of China, Ltd, the
insured amount for our manufacturing facilities in Tianjin is RMB220,991,420
(approximately $33.0 million) for the period from July 2, 2010 to July 2, 2011.

The Company is not able to insure its new Research and
Development Test Centre to be constructed in Shenzhen, China, until it receives
the required property ownership and land use rights certificates. Upon receipt
of such certificates, the Company intends to procure such insurance. As
discussed above, the Company has obtained the land use rights certificate to the
land relating to these facilities. The application for a property ownership
certificate is in process with respect to the Companys facilities in Shenzhen.

Overview

We are a leading global manufacturer of lithium based battery cells. We produce battery cells that are the principal component of rechargeable batteries commonly used to power the following applications:

- cellular phones and smart phonescustomer categories include OEM customers and replacement battery manufacturers;
- notebook computers;
- portable consumer electronics, such as digital cameras, portable media players, portable gaming devices, personal digital assistants, or PDAs, camcorders, digital cameras, and Bluetooth headsets; and
- light electric vehicles, hybrid electric vehicles, electric vehicles, cordless power tools, and uninterruptible power supplies, or UPS.

We conduct all of our operations in China, in close proximity to Chinas electronics manufacturing base and its rapidly growing market. Historically, we have primarily manufactured prismatic lithium-ion cells for the cellular phone replacement
battery market and the OEM market. Our products are packed into batteries by third-party battery pack manufacturers in accordance with the specifications of manufacturers of portable electronic applications. At the request of our customers that
order prismatic battery packs, we also engage battery pack manufacturers to assemble our prismatic cells into batteries for a fee and then sell battery packs to these customers both for the replacement and OEM markets.

As we expand our production capacity and add other lithium-ion battery cell product lines in response to evolving market demands, we have derived and will continue to derive an increasing portion of our revenues from our other product lines.

First Fiscal Quarter Financial Performance Highlights

During the first quarter of fiscal year 2011, we generated $63.5 million in net revenues, an increase of 14.3% from $55.6 million in the fourth quarter 2010, and up
26.5% from $50.2 million in the first quarter of 2010.

The following achievements were accomplished in the first quarter of fiscal year 2011:

- Revenue increased 26.5% year-over-year and 14.3% quarter on quarter (compared to the fiscal quarter ended September 30, 2010)
- Revenues from high-power batteries more than tripled in the fiscal quarter ended December 31, 2010 compared to the fiscal quarter ended September 30, 2010 due to robust demand for batteries used in energy storage solutions, including UPS
- Gross margin improved to 15.7% in the first quarter of fiscal year 2011 from 9.5% in the previous quarter
- Reported another quarter of positive cash flow of $18.4 million from operating activities, reflecting continued progress in the Companys turnaround plan
- Days Sales Outstanding declined to 126 days from 134 days last quarter and Days Sales of Inventory declined to 110 days from 115 days in the previous quarter
- In November 2010, Chery Automobile Co., Ltd. officially launched its first Lithium-ion-based electric vehicle, Ruilin M1, powered by China BAKs lithium-ion phosphate batteries at the 25th World Electric Vehicle Symposium and Exposition
- BAK Tianjin received a subsidy of approximately $7.5 million for its automated high power lithium battery project in December 2010

Gross profit for the first quarter of fiscal year 2011 was $10.0 million, up 88.3% from $5.3 million last quarter and up 4.6% from $9.6 million in the same quarter of last year. Gross margin was 15.7%, up from 9.5% last quarter and
slightly lower than 19.0% in the same period last year. The increase in gross profit was primarily a result of increased direct sales of battery packs to OEM cell phone manufacturers driven by strong customer demand. The year-over-year decline in
gross margin was primarily a result of the Companys adoption of a competitive pricing strategy for its cylindrical cells to increase its market share in the OEM market.

We had access to $222.5 million in short-term credit facilities and $53.0 million in long-term credit facilities as of December 31, 2010. As of December 31, 2010, the principal outstanding amounts included short-term bank loans of $139.8
million, long-term bank loans of $15.1 million maturing within one year, and long-term bank loans of $22.7 million maturing in over one year, and bills payable of $51.5 million, leaving $66.9 million of short-term funds available for
additional cash needs. In addition, on July 10, 2008, our $60 million shelf registration statement was declared effective by the SEC, pursuant to which we have raised $36.6 million in gross proceeds from sales of common stock and issued
common stock warrants exercisable for up to $21.6 million in additional gross proceeds. As $16 million of these warrants were not exercised before their expiration, we may raise up to an additional $17.8 million in gross proceeds from
future equity financings under this shelf registration statement.

Financial Statement Presentation

Net revenues. Our net revenues represent the invoice value of our products sold, net of value added taxes, or VAT, sales returns, trade discounts and allowances. We are subject to VAT, which is levied on most of our products at the
rate of 17% on the invoice value of our products. Provision for sales returns are recorded as a reduction of revenue in the same period that revenue is recognized. The provision for sales returns represents our best estimate of the amount of goods
that will be returned from our customers based on historical sales returns data.

Cost of Revenues. Cost of revenues consists primarily of material costs, employee remuneration for staff engaged in production activity, equity-based compensation, depreciation and related expenses that are directly attributable to the
production of products. Cost of revenues also includes write-downs of inventory to lower of cost or market. Cost of revenues from the sales of battery packs includes the fees we pay to pack manufacturers for assembling our prismatic cells into
battery packs.

Research and Development Expenses. Research and development expenses are primarily comprised of remuneration for R&D staff, equity-based compensation, depreciation and maintenance expenses relating to R&D equipment, and R&D
material costs.

Sales and Marketing Expenses. Sales and marketing expenses consist primarily of remuneration for staff involved in selling and marketing efforts, including staff engaged in the packaging of goods for shipment, advertising cost,
depreciation, equity-based compensation and travel and entertainment expenses. We do not pay slotting fees to retail companies for displaying our products, engage in cooperative advertising programs, participate in buy-down programs or similar
arrangements. No material estimates are required by management to determine our actual marketing or advertising costs for any period.

General and Administrative Expenses. General and administrative expenses consist primarily of employee remuneration, equity-based compensation, professional fees, insurance, benefits, general office expenses, depreciation, liquidated
damages, and bad debt expenses.

Finance Costs, Net. Finance costs consist primarily of interest income, interest on bank loans, net of capitalized interest, and bank charges.

Government Grant Income. Income from government grants consisted primarily of grant funds awarded to Shenzhen BAK as consideration for its contributions to the Shenzhen areas economy and as
subsidies for land-use rights at BAK Industrial Park. No present or future
obligations arise from the receipt of these funds.

Income Taxes. Under PRC income tax laws and regulations, before January 1, 2008, a foreign-invested enterprise, or FIE, was generally subject to an enterprise income tax rate of 33.0%, which included a 30.0% state income tax and a 3.0%
local income tax. However, from at least calendar year 2002 through calendar year 2007, an enterprise recognized as a Manufacturing Enterprise Located in Special Economic Zone under PRC tax laws was entitled to a preferential income tax
rate of 15%. Moreover, a foreign-invested manufacturing enterprise, starting from its first profitable calendar year after offset of accumulated tax losses, was entitled to a two-year exemption from enterprise income tax followed by a three-year 50%
reduction in its enterprise income tax rate, also referred to herein as the tax holiday. An enterprise qualified for such treatment may receive a further tax rate reduction related to the size of qualified capital contributions received.
In addition, from at least calendar year 2002 through calendar year 2007, an enterprise qualified as an advanced technology enterprise under PRC tax law was also entitled to a 50% reduction of income taxes.

On March 16, 2007, the National Peoples Congress of the PRC determined to adopt the new corporate income tax law, or the New CIT Law. The New CIT Law unifies the application scope, tax rate, tax deduction and preferential policy for both
domestic enterprises and FIEs. The New CIT Law became effective on January 1, 2008. According to the New CIT Law, the applicable income tax rate for Shenzhen BAK, BAK Electronics and BAK Tianjin will be 25% after their preferential tax holidays and
the transition period have ended. During the transition period, tax rates for subject entities was 18% and 20% for the calendar years 2008 and 2009, respectively, and is expected to be 22% and 24% for the calendar years 2010 and 2011, respectively,
before the application of applicable tax holidays or other tax preferences.

Shenzhen BAK and BAK Electronics are both registered and operate in Shenzhen, the PRC, and are each recognized as Manufacturing Enterprise Located in Special Economic Zone. As a result, they have been entitled to a preferential
enterprise income tax rate of 15%. In accordance with the relevant income tax laws, the profits of Shenzhen BAK and BAK Electronics were fully exempted from income tax for two years from the first profitable calendar year of operations after offset
of accumulated taxable losses, followed by a 50% exemption for the immediate next three calendar years.

The tax holiday of Shenzhen BAK commenced in 2002, the first calendar year in which Shenzhen BAK had assessable profit, and ended on December 31, 2006. In addition, due to additional capital contributed by BAK International to Shenzhen BAK in both
2005 and 2006 and Shenzhen BAKs qualification as an advanced technology enterprise in 2007 and 2008, Shenzhen BAK was granted a preferential income tax rate of 7.5%, 11.8% and 12.6% for calendar years 2007, 2008 and 2009, respectively. In
accordance with the transition period of the New CIT Law and before considering the above-mentioned tax concessions, Shenzhen BAKs income tax rate for calendar years 2010 and 2011 are expected to be 22% and 24%, respectively, and starting in
calendar year 2012, it is expected to be subject to an income tax rate of 25%.

---

Therefore, Shenzhen BAKs income tax rates after consideration
of its tax concessions are expected to be 15% for both calendar years 2010 and
2011and starting in calendar year 2012, it is expected to be subject to an
income tax rate of 25%.

For BAK Electronics, established in August 2005, the same tax
holiday was in effect for calendar years 2006 and 2007, making BAK Electronics
fully exempt from any enterprise income tax. Following the tax holiday, a
three-year 50% reduction in BAK Electronics enterprise income tax rate
commenced. Pursuant to the transition period of the New CIT Law, BAK
Electronics income tax rates for calendar years 2010 and 2011 were expected to
be 22% and 24%, respectively, and starting in calendar year 2012 it was expected
to be subject to an income tax rate of 25%. Taking the 50% reduction into
account, BAK Electronics income tax rates are now expected to be 11% and 24%
for calendar years 2010 and 2011, respectively, with no change in its expected
2012 tax rate of 25%. BAK Electronics did not incur any enterprise income tax
for calendar year 2010 due to the current tax losses.

Shenzhen BAK and BAK Electronics received in aggregate a tax
benefit of $233,000 pursuant to their transitional tax rate for the three months
ended December 31, 2010, or $0.004 per basic share.

BAK Tianjin is currently paying no enterprise income tax due to
cumulative tax losses.

Our Canadian, German, Indian, and Hong Kong subsidiariesBAK
Canada, BAK Europe, BAK India, and BAK Internationalare subject to profits
taxes in their respective countries at rates of 38%, 25%, 30%, and 16.5%
respectively. However, because they do not have any assessable income derived
from or arising in those countries, they have not paid any such tax.

Our effective tax benefit rate was 3.5% for the three months
ended December 31, 2010 and our effective tax benefit rate was 27.3% for the
three months ended December 31, 2009.

Pursuant to the Provisional Regulation of China on Value Added
Tax and its implementing rules, all entities and individuals that are engaged in
the sale of goods, the provision of repairs and replacement services and the
importation of goods in China are generally required to pay VAT at a rate of
17.0% of the gross sales proceeds received, less any deductible VAT already paid
or borne by the taxpayer. Further, when exporting goods, the exporter is
entitled to some or all of the refund of VAT that it has already paid or borne.
Our imported raw materials that are used for manufacturing export products and
are deposited in bonded warehouses are exempt from import VAT.

- Net revenues from sales of aluminum-case cells increased to $30.6 million
  in the three months ended December 31, 2010, from $27.9 million in the same
  period in fiscal year 2010, an increase of $2.7 million or 9.8%, resulting
  from sales volume of 4.3% driven by increase sales to the OEM market in the
  PRC and an increase of 4.1% in our average selling price.
- Net revenues from sales of battery packs increased to $16.9 million in the
  three months ended December 31, 2010, from $10.9 million in the same period in
  fiscal year 2010, an increase of $6.0 million or 54.7%. This resulted from an
  increase in sales volume of 59.1% due to increased export sales and domestic
  market sales in the PRC, offset by a 2.8% decrease in average selling price.
- Net revenues from sales of cylindrical cells increased to $10.5 million in
  the three months ended December 31, 2010, from $8.1 million in the same period
  in fiscal year 2010, an increase of $2.5 million or 29.1%. This result was the
  net effect of a 38.4% increase in sales volume driven primarily by increased
  sales to laptop manufacturers, offset by a decrease in our average selling
  prices of 6.6% due to our competitive pricing strategy for the cylindrical
  battery cells to increase our market share in the OEM market.
- We sold $3.5 million in lithium polymer cells in the three months ended
  December 31, 2010, compared to $3.2 million in lithium polymer cells in the
  same period in fiscal year 2010, a slight increase of $298,000 or 9.4%,
  resulting from a 35.7% increase in average selling price, offset by a 17.7%
  decrease in sales volume as a result of fierce competition.
- We also sold approximately $2.1 million in high-power lithium battery
  cells in the three months ended December 31, 2010, as compared to $163,000 in
  high-power lithium battery cells in the same period of fiscal year 2010, due
  to our sale of sample products used in electric buses, electric vehicles,
  electric bicycles, power tools, uninterruptible power supplies, and other
  applications from our Tianjin facility.

Cost of Revenues. Cost of revenues increased to
$53.5 million for the three months ended December 31, 2010, as compared to $40.7
million for the same period in fiscal year 2010, an increase of $12.9 million or
31.6% . The increase in cost of revenues correlates to an increase in sales
volume over the three months ended December 31, 2010.

As a result, gross profit for the three months ended December
31, 2010 was $10.0 million, or 15.7% of net revenues, as compared to gross
profit of $9.6 million, or 19.0% of net revenues, for the same period in fiscal
year 2010. The decrease in gross profit as a percentage of net revenues was
primarily due to a decrease in the average selling price of cylindrical battery
cells, resulting from the temporary competitive-pricing strategy implemented in
order to maintain and increase our market share in the OEM market.

Research and Development Costs. Research and
development costs decreased to $1.6 million for the three months ended December
31, 2010, as compared to $1.8 million for the same period in fiscal year 2010, a
decrease of $123,000 or 7.0% . Equity-based compensation included in R&D
costs decreased by $90,000 as charges relating to outstanding stock options to
R&D staff had already been reflected in large part in fiscal periods prior
to fiscal year 2011.

Sales and Marketing Expenses. Sales and marketing expenses increased to $2.3 million for the three months ended December 31, 2010, as compared to $2.0 million for the same period in fiscal year 2010, an increase of
$245,000, or 12.1% . Salaries and welfare increased $205,000 primarily due to increased basic salaries and benefits in response to guidance issued to Shenzhen-based companies by relevant local government authorities during the three months
ended June 30, 2010 and effective July 1, 2010. As a percentage of revenues, sales and marketing expenses have decreased to 3.6% for the three months ended December 31, 2010 from 4.0% for the same period in fiscal year 2010, due to the significant
increase in revenues from sales.

General and Administrative Expenses. General and administrative expenses decreased to $7.9 million, or 12.4% of revenues, for the three months ended December 31, 2010, as compared to $8.6 million, or 17.2% of revenues, for the
same period in fiscal year 2010, a decrease of $758,000 million, or 8.8%. Bad debt expenses decreased, during the three months ended December 31, 2010, by $1.7 million. We also recognized the exchange loss of $755,000 for the three months ended December 31, 2010, compared with exchange gain of $150,000 for the three months ended December 31, 2009.

Operating Loss. As a result of the above, operating loss totaled $1.8 million for the three months ended December 31, 2010, as compared to $2.9 million for the same period of the prior year. As a percentage of net revenues,
operating loss was 2.8% for the three months ended December 31, 2010, as compared to operating loss of 5.7% for the same period of the prior fiscal year.

Finance Costs, Net. Finance costs, net, increased to $2.8 million for the three months ended December 31, 2010, as compared to $2.2 million for the same period of the prior fiscal year, an increase of $687,000 or 31.9% .
This increase mainly was due to an increase in discounts charged for bills receivable recognized during the three months ended December 31, 2010.

Government Grant Income / Other Income / (Other Expenses).We had deferred revenue from government grant income of $607,000and other income of $241,000for the three-month period ended December 31,
2010, as compared to government grant income of $355,000 and other income of $7,000for the same period of the prior fiscal year. The government grant income for the three months ended December 31, 2010 and December 31, 2009 mainly
consisted of subsidies to pay for the land use rights to our corporate campus at BAK Industrial Park and government grant funds to subsidize certain lithium battery projects. No present or future obligation will arise from the receipt of such
income.

Income Tax Benefits. Income tax benefits were $134,000 for the three months ended December 31, 2010, as compared to income tax benefits of $1.3 million for the same period of fiscal year 2010. The change was the result of a
deferred tax provision during the three months ended December 31, 2010.

Net Loss. As a result of the foregoing, we had a net loss of $3.7 million for the three months ended December 31, 2010 compared to $3.4 million for the same period of 2009.

Liquidity and Capital Resources

We have historically financed our liquidity requirements from a variety of sources, including short-term bank loans, long-term bank loans and bills payable under bank credit agreements, sale of bills receivable and issuance of capital stock. As of
December 31, 2010, we had cash and cash equivalents of $24.5 million, as compared to $22.6 million as of September 30, 2010 and $18.3 million as of December 31, 2009. In addition, we had pledged deposits amounting to $16.4 million
and $9.4 million as of December 31, 2010 and September 30, 2010, respectively. Typically, our banks require their borrowers to maintain deposits of approximately 10% to 100% of the outstanding loan balances and bills payable. The individual bank
loans have maturities ranging from three to twelve months which coincides with the periods the cash remains pledged to the banks.

We had access to $222.5 million in short-term credit facilities and $53.0 million in long-term credit facilities as of December 31, 2010. As of December 31, 2010, the principal outstanding amounts included short-term bank loans of $139.8
million, long-term bank loans of $15.1 million maturing within one year, and long-term bank loans of $22.7 million maturing in over one year, and bills payable of $51.5 million, leaving $66.9 million of short-term funds available for
additional cash needs. In addition, on July 10, 2008, our $60.0 million shelf registration statement was declared effective by the SEC, pursuant to which we have raised $36.6 million in gross revenue from common stock purchases and issued
common stock warrants exercisable for up to $21.6 million in additional gross proceeds. As $16.0 million of these warrants were not exercised before their expiration, we may raise up to
an additional $17.8 million in gross proceeds from future equity financings
under this shelf registration statement.

the three months ended December 31, 2010, compared to $17.4 million of net cash
used in operating activities in the same period in fiscal year 2010. The

cash deposits at banks as collateral in the three months ended December 31,
2010, and (iii) decreased borrowings, net of repayments, of $18.7 million in the

The above principal outstanding amounts under credit facilities
and lines of credit included short-term bank loans of $139.8 million, long-term
bank loans of $15.1 million maturing within one year and long-term bank loans of
$22.7million maturing in over one year, and bills payable of $51.5
million.

For the purpose of presentation, the effect of increases in
bills payable balances is included in operating activities in the statements of
cash flows.

During the three months ended December 31, 2010, we repaid

loans totaling approximately $31.8 million, renewed a comprehensive credit
facility agreement with a maximum loan amount of approximately $75.7 million,
and entered into  new short-term bank loan agreements totaling
approximately $27.8 million. The material financing terms of these loans are
described below.

On November 15, 2010, we renewed our comprehensive credit
facility agreement with Agricultural Bank of China, Shenzhen Eastern Branch, or
Agricultural Bank  Shenzhen Branch, to provide a maximum loan amount of RMB 500
million (approximately $75.7 million), including RMB 400 million (approximately
$60.6 million) of one-year term credit facilities and RMB 100 million
(approximately $15.1 million) of five-year term credit facilities. This
comprehensive credit facility agreement renewed a predecessor credit facility
agreement between Shenzhen BAK and Agricultural Bank  Shenzhen Branch dated
November 26, 2009 and governs all loans that were subject to the predecessor
agreement at the time of the renewal. New
loans may be drawn under this credit facility from November 15, 2010 through November
10, 2011, with the term of the loan established at the time each new loan is drawn, except as to funds borrowed under a loan agreement between Shenzhen BAK
and Agricultural Bank  Shenzhen Branch dated November 23, 2006 and effective
December 18, 2006, or the 2006 Loan Agreement, which may be drawn at any time within five years of December 18, 2006, and which will mature five years after such
funds are drawn. Pursuant to the comprehensive credit facility, Shenzhen BAK must obtain prior approval from Agricultural Bank  Shenzhen Branch to renew long-term loans that are subject to this credit facility. In addition, Shenzhen BAK
undertook to ensure that the percentage of certain business conducted with Agricultural Bank  Shenzhen Branch relative to such business it conducts with all financial institutions combined be at least equal to the percentage of its
indebtedness to Agricultural Bank  Shenzhen Branch relative to its indebtedness to all financial institutions combined (referred to as the Percentages Undertaking). The business referred to in the preceding sentence
refers to the volume of transactional payments that are drawn from Shenzhen BAKs accounts with Agricultural Bank Shenzhen Branch or applicable financial institutions and the amount of foreign currencies deposited with Agricultural Bank
 Shenzhen Branch or applicable financial institutions. Shenzhen BAK also undertook not to issue any dividends without the written consent of Agricultural Bank  Shenzhen Branch prior to the expiration of all loans under this credit
facility (this undertaking and the Percentages Undertaking are collectively referred to as the Undertakings). The obligations of Shenzhen BAK under this comprehensive credit facility are guaranteed by Mr. Xiangqian Li, BAK Tianjin, and
BAK International. Shenzhen BAKs obligations under this credit facility agreement are also guaranteed by Shenzhen BAKs pledge of the property ownership and land use rights certificates relating to its manufacturing and other facilities
in Shenzhen, PRC, known as BAK Industrial Park. In the event that Shenzhen BAK breaches any of the Undertakings or any guaranteed party breaches any of its guaranty obligations,
Agricultural Bank  Shenzhen Branch may, in addition to exercising any other
applicable remedies under the applicable agreements, accelerate repayment of all
loan amounts governed by this credit facility.

During the fiscal quarter ended
December 31, 2010, we had seven
outstanding short-term loans under the comprehensive credit facility with
Agricultural Bank  Shenzhen Branch totaling approximately $72.0 million. The first
loan, of approximately $11.4 million, carried annual interest at 5.31%, and was due on January 6, 2011. The second
loan, of approximately $7.6 million, carried annual interest at 5.56%, and  was due on January 21, 2011. The third
loan, of approximately $7.6 million, carried annual interest at 5.56%, and was
due on January 22, 2011. We repaid each of the foregoing three loans on its
respective due date. The fourth loan, of approximately $9.0 million, currently
carries annual interest at 5.282% and is due on April 20, 2011. The fifth loan,
of approximately $11.4 million, carries annual interest at 5.282% and is due on
April 22, 2011. The sixth loan, of approximately $13.6 million, currently
carries annual interest at 5.282% and is due on April 19, 2011. The seventh
loan, of approximately $11.4 million, currently carries annual interest at 95%
of the benchmark rate of  the People's Bank of China, or PBOC and is due on December 21, 2011. Each of the loan
agreements specifically provides for acceleration of repayment of the loan under
certain conditions, as well as other penalties and remedies. Agricultural Bank -
Shenzhen Branch permitted us to obtain the seventh loan under this credit
facility notwithstanding that we had borrowed the maximum amount of one-year
term loans under this facility on the date of such loan.

As of December 31, 2010, we also had two five-year term loans
totaling approximately $15.1 million under the Agricultural Bank  Shenzhen
Branch comprehensive credit facility carrying interest at 90% of the benchmark

approximately $6.0 million, currently carries annual
interest of 5.184% and is due on January 25, 2012. The second loan, of approximately $9.1 million, currently carries annual interest of 5.184% and is due in two installments of approximately $7.5 million on January 25, 2011, and
approximately $1.6 million on January 25, 2012, respectively. The
installment due on January 25, 2011 was repaid on that date. These five-year term loans are specifically: (i) guaranteed by Mr. Xiangqian Li; (ii) secured by Shenzhen BAKs machinery and equipment with carrying values of approximately
$31.2 million as of December 31, 2010; and (iii) secured by the property ownership and land use rights certificates with an aggregate net book value of $111.1 million as of December 31, 2010 in relation to the land on which Shenzhen BAKs corporate campus had been constructed and any machinery and equipment purchased and used at the campus subsequent to such construction.

As of December 31, 2010, we had a six-year long-term loan agreement expiring on December 30, 2015 of RMB 150 million (approximately $22.7 million) with Shenzhen Branch, China Development Bank, or China Development Bank. The long-term loan is
secured by Shenzhen BAKs pledge of its land use rights certificates, property ownership and equipment built-up by use of this long-term loan pursuant to the loan agreement. According to the property ownership and land use rights certificate
that we obtained in relation to this facility, the certificate may not be pledged without the approval of the relevant government office. On April 7, 2010, the pledge of the land use rights certificate to China Development Bank was approved by the
relevant government bureau. For further discussion regarding the status of property ownership rights relating to this facility, please see Managements Discussion and Analysis of Financial Condition and Results of Operations 
Capital Expenditures. The obligations of Shenzhen BAK under this loan agreement are guaranteed by Mr. Xiangqian Li. We had borrowed approximately $7.6million under a loan agreement dated March 1, 2010, bearing annual interest of
5.90%, adjusted monthly, and repayable within 72 months.

During the fiscal quarter ended December 31, 2010, we had a comprehensive credit facility agreement with Shenzhen Hi-Tech District Branch, Industrial Bank, or Industrial Bank, for a maximum loan amount of RMB 62.5 million (approximately $9.3
million). This credit facility agreement was guaranteed by BAK International, BAK Tianjin and Mr. Xiangqian Li. Loans may be drawn at any time from March 31, 2010 to December 31, 2010. During the quarter ended December 31, 2010, we had borrowings of
approximately $7.6million under a loan agreement dated January 6, 2010 bearing fixed interest of 4.779%, and which was repayable on December 31, 2010 under this credit facility agreement. We repaid this loan on December 31, 2010.

As of December 31, 2010, we had a comprehensive credit facility agreement with Tianjin Branch, Bank of Dalian, or Bank of Dalian, for a maximum loan amount of RMB 40 million (approximately $6.1 million). If we increase paid-up capital by $20
million, then an additional RMB 10 million of credit facilities would be available. If we pay up 50% of our total registered capital, then another additional RMB 10 million of credit facilities would be available. If we pay up all our registered
capital, the total amount of available credit under this facility would be RMB 80 million (approximately $12.0 million). This credit facility agreement is guaranteed by Shenzhen BAK and Mr. Xiangqian Li. Loans may be drawn at any time from
November 27, 2009 to November 26, 2010. During the fiscal quarter ended December 31, 2010, we had borrowed approximately $6.1million under a loan agreement dated October 27, 2010, bearing annual interest of 6.116%, adjusted monthly,

On September 28, 2009, we entered into a guaranty contract with
Shanghai Pudong Development Bank to provide guaranty for the loans drawn from
September 28, 2009 to August 31, 2010, and the maximum amount for all loans will
be less than RMB 30 million (approximately $4.5 million). As of December 31,
2010, we had borrowed approximately $4.7 million of notes payable outside any
credit facility.

As of December 31, 2010, we had a four-year, long-term loan
agreement expiring May 26, 2012 of RMB 100 million (approximately $15.1 million)
with Agricultural Bank of China, Tianjin Branch, or Agricultural Bank  Tianjin
Branch. This loan agreement is secured by the machinery and equipment purchased
for the automated high-power lithium battery cells production line at our
Tianjin facility. As of December 31, 2010, we had borrowed $15.1 million under
this loan agreement, payable in three installments: (i) RMB 50 million
(approximately $7.5 million) on December 26, 2011; and(ii) RMB 50 million
(approximately $7.6 million) on May 26, 2012.

We had negative working capital of $72.7 million as of December
31, 2010, as compared to negative working capital of $70.8 million as of
September 30, 2010. Current assets as of December 31, 2010 were $212.5 million
compared with $194.7 million as of September 30, 2010, an increase of $17.9
million. Current liabilities as of December 31, 2010 were $285.2 million
compared with $265.5 million as of September 30, 2010, an increase of $19.7
million. We had short-term bank loans maturing in less than one year of $139.8
million and long-term bank loans maturing within one year of $15.1 million as
of December 31, 2010, or a total of $154.9 million of loans maturing within one
year, as compared to a total of $149.4 millionof such loans as of
September 30, 2010, an increase of $5.5 million. We had long-term bank loans
maturing in over one year of $22.7 million as of December 31, 2010, as compared
to $29.9 million of such loans as of September 30, 2010, a decrease of $7.2
million.

We believe that our current cash and cash equivalents and
anticipated cash flow from operations will be sufficient to meet our anticipated
cash needs, including our cash needs for working capital and capital
expenditures for at least the next 12 months. We may, however, require
additional cash due to changing business conditions or other future
developments, including any investments or acquisitions we may decide to pursue.
If our existing cash and amount available under existing credit facilities is
insufficient to meet our requirements, we may seek to sell additional equity
securities, debt securities or borrow from lending institutions. We can make no
assurances that financing will be available in the amounts we need or on terms
acceptable to us, if at all. The sale of additional equity securities, including
convertible debt securities, would dilute the interests of our current
shareholders. The incurrence of debt would divert cash for working capital and
capital expenditures to service debt obligations and could result in operating
and financial covenants that restrict our operations and our ability to pay
dividends to our shareholders. If we are unable to obtain additional equity or
debt financing as required, our business operations and prospects may
suffer.

Capital Expenditures

We made capital expenditures of $6.0 million and $3.9 million
in the three months ended December 31, 2010 and 2009, respectively. Our capital
expenditures were used primarily to purchase plant and equipment to expand our
production capacity.

|The following table sets forth the
      breakdown of our capital expenditures by use for the periods indicated. |   |                    |  |

We estimate that our total capital expenditures in fiscal year
2011 will reach approximately $35.0 million, to purchase manufacturing equipment
for the expansion of our production lines and for the construction of our new
Research and Development Test Centre at our Shenzhen facility.

We have completed the construction and put into use facilities measuring 218,178 square meters comprised of manufacturing facilities, warehousing and packaging facilities, dormitory space, dining halls and administrative offices at the BAK
Industrial Park in Shenzhen. Of that space, approximately 81,411 square meters are manufacturing facilities. We have also completed the construction and put into use facilities measuring 65,907 square meters comprised of manufacturing facilities,
dormitory space, dining halls and other facilities in Tianjin. Of that space, approximately 44,129 square meters are manufacturing facilities. The primary reasons for our continuing investments in the facilities in Tianjin are to realize the
benefits of our prior investment in these facilities, to position the Company to capitalize on our knowledge of and experience with established markets for lithium-phosphate technology, such as electric bicycles, cordless power tools, and to
penetrate emerging consuming markets for this technology, such as electric cars, electric buses, light electric vehicles, and hybrid electric vehicles. We have received several contracts to supply high-power lithium cells for use in electric cars,
electric bicycles, UPS, and other applications.

According to the relevant PRC laws and regulations, a land use right certificate, along with government approvals for land planning, project planning, and construction must be obtained before the construction of any building is commenced. An
ownership certificate will be granted by the government upon application under the condition that the aforementioned certificate and government approvals are obtained. We recently obtained the land use right to the tract of property on which we have
constructed and on which we plan further construction of our manufacturing facilities and other related facilities in Shenzhen. While we have been constructing and have completed a substantial part of the construction of our facilities with the
approval of the local government of Kuichong Township of Longgang District of Shenzhen, we understand it did not have the authority to grant us the land use rights certificate. However, the Company obtained approval for project planning and
construction from the government of Shenzhen on June 20, 2007. Under an agreement with the government of Shenzhen for the acquisition of the land use rights to BAK Industrial Park dated June 29, 2007, effective June 2008, the government agreed to
provide us with the land use rights certificate relating to BAK Industrial Park on the condition that the Company would pay it an additional $11,819,841. According to a notice received from the government of Shenzhen on June 6, 2008, the Company
obtained government grants of $7,889,991 to subsidize this additional payment. As of September 30, 2008, the Company had fully paid the remaining cost of $3,929,850 and had obtained the land use rights certificate for BAK Industrial Park.

We have insurance for our manufacturing facilities for Shenzhen BAK located in BAK Industrial Park and our manufacturing facilities at our Tianjin facility. However, we are not able to insure our new Research and Development Test Centre to be
constructed in Shenzhen, China, until we receive the required certificate of property ownership. Upon receipt of the certificate of property ownership, we intend to procure such insurance. The applications for the related certificates of property
ownership rights are in process with respect to our facilities at BAK Industrial Park and Tianjin (see discussion of our Research and Development Test Centre below). As we have been granted the land use rights certificate to the premises presently
occupied by the Company in BAK Industrial Park, there should be no legal barriers for us to obtain a property ownership certificate for this property. However, it is possible that the Shenzhen government may determine that even with our land use
rights certificate, the buildings constructed at BAK Industrial Park were still constructed without the proper authority and must be vacated as illegitimate constructions, and we might be subject to penalties and fines. However, we believe that this
possibility, while present, is remote.

As of September 30, 2007, we had fully paid the lease prepayment amount of $14.1 million for the acquisition of land use rights regarding our Tianjin facility. As of September 30, 2008, we had obtained the relevant land use rights certificate to
this facility. As of December 31, 2010, we were in the process of obtaining the relevant property ownership rights certificate to this facility.

Pursuant to our land use rights certificate relating to our Tianjin facility, the Tianjin government had originally requested that we complete construction of the Tianjin facility before September 30, 2008. As of September 30, 2008, we had not done
so. Notwithstanding this requirement, we have obtained an extension from the Business Administration Bureau of Beichen District, Tianjin, to make the remaining contribution of the registered capital by December 11, 2009, which we interpreted as an
extension of the completion date of construction to this date. On November 16, 2009, BAK International contributed approximately US$9,000,000 capital to BAK Tianjin and as of November 16, 2009, the total contribution from BAK International was
US$29,000,000. The remaining US$70,990,000 was originally required to be fully contributed no later than December 11, 2009 and an extension from the Business Administration Bureau of Beichen District, Tianjin, was obtained to complete this
contribution no later than December 2012. As of December 31, 2010, we were in the process of negotiating with the relevant government bureau for the extension of the completion date of the construction of the Tianjin facility.

As of September 30, 2007, we had paid the lease prepayment amount of $717,000 for the acquisition of land use rights for a new Research and Development Test Centre to be constructed in Shenzhen, China. As of September 30, 2008, we had obtained
the relevant property ownership and land use rights certificate. Pursuant to the property ownership and land use rights certificate, we are required to complete at least 25% of the construction of the new Research and Development Test Centre
facility by September 30, 2008. As of September 30, 2008, we had not done so. Notwithstanding this requirement, the Shenzhen government has agreed to increase the dimensions of the Research and Development Test Centre and signed two supplemental
agreements with us. According to the supplemental agreements, we are required to complete the construction by May 6, 2011. In addition, according to the property ownership and land use rights certificate, such land may not be pledged without the
approval of the relevant government office. We are required to pledge our property ownership and land use rights certificate in relation to the new Research and Development Test Centre to China Development Bank pursuant to the loan agreement entered
into with it. On April 7, 2010, the pledge of the land use rights certificate to China Development Bank was approved by the relevant government bureau. On April 20, 2010, the relevant land use rights certificate was pledged to China Development
Bank. In addition, the so-named property ownership and land use rights certificate relating to this facility that we were issued lacks certain terms relating to property ownership rights, which appears to indicate that the granting
government has so far only granted us the relevant land use rights. As a result, this certificate may not be adequate evidence of our property ownership rights to this property. We anticipate that the government will re-grant this certificate with
adequate property ownership indicia after we have satisfied the above construction requirement and followed certain procedures.

Contractual Obligations and Commercial Commitments

Please refer to Item 7, Managements Discussion and Analysis of Financial Condition and Results of Operations  Contractual Obligations and Commercial Commitments in the 2010 Form 10-K for a discussion of our contractual
obligations and commercial commitments as of September 30, 2010. There were no material changes outside the ordinary course of our business in our contractual obligations and commercial commitments for the quarter ended December 31, 2010.

Off-Balance Sheet Transactions

In the ordinary course of business practices in China, we enter into transactions with banks or other lenders where we guarantee the debt of other parties. These parties may be related to or unrelated to us. Conversely, our debt with lenders may
also be guaranteed by other parties which may be related or unrelated to us.

Under U.S. GAAP, these transactions may not be recorded on our balance sheet or may be recorded in amounts different than the full contract or notional amount of the transaction. Our primary off-balance sheet arrangements would result from our loan
guaranties in which Shenzhen BAK, BAK International, BAK Tianjin, and/or Mr. Xiangqian Li, our director, Chairman, President, and Chief Executive Officer, would provide contractual assurance of the debt, or guarantee the timely re-payment of
principal and interest of the guaranteed party. Neither Shenzhen BAK, BAK International, BAK Tianjin, nor Mr. Xiangqian Li received, nor is entitled to receive, any consideration for the above-referenced guarantees, and we are not independently
obligated to indemnify any of those guarantors for any amounts paid by them pursuant to any guarantee.

Typically, no fees are received for this service. Thus, in those transactions, Shenzhen BAK would have a contingent obligation related to the guarantee of payment in the event the underlying loan is in default.

Transactions described above require accounting treatment under ASC Topic 460 Guarantees. Under that standard, we would be required to recognize the fair value of guarantees issued or modified after December 31, 2002, for non-contingent
guarantee obligations, and also a liability for contingent guarantee obligations based on the probability that the guaranteed party will not perform under the contractual terms of the guaranty agreement.

We have assessed the contingent liabilities arising from the above-described guarantees and have considered them immaterial to the consolidated financial statements. Therefore, no liabilities in respect of the guarantees were recognized as of
December 31, 2010. As of December 31, 2010, we provided the guarantees for the non-related parties, Nanjing Special Metal Equipment Co., Ltd., Hunan Reshine New Material Ltd, Shenzhen Tongli Hi-tech Co. Ltd., Shenzhen B&G Technology Development
Co. Ltd., Shanghai Global Children Products Co. Ltd., Shenzhen Yasu Technology Co. Ltd., Beijing Triolion Technology Co. Ltd. and Siping Juyuan Hanyang Plate Heat Exchanger Co. Ltd. The maximum amount of our exposure for these guarantees was
$40.7 million and $40.2 million at December 31, 2010 and September 30, 2010, respectively.

Critical Accounting Policies

Our consolidated financial information has been prepared in accordance with U.S.
GAAP, which requires us to make judgments, estimates and assumptions that affect
(1) the reported amounts of our assets and liabilities, (2) the disclosure of
our contingent assets and liabilities at the end of each fiscal period and (3) the reported amounts of revenues and expenses during each fiscal period. We continually evaluate these estimates based on our own historical experience, knowledge and
assessment of current business and other conditions, our expectations regarding the future based on available information and reasonable assumptions, which together form our basis for making judgments about matters that are not readily apparent from
other sources. Since the use of estimates is an integral component of the financial reporting process, our actual results could differ from those estimates. Some of our accounting policies require a higher degree of judgment than others in their
application.

When reviewing our financial statements, the following should also be considered: (1) our selection of critical accounting policies, (2) the judgment and other uncertainties affecting the application of those policies, and (3) the sensitivity of
reported results to changes in conditions and assumptions. We believe the following accounting policies involve the most significant judgment and estimates used in the preparation of our financial statements.

Recoverability of Long-Lived Assets

Our business is capital intensive and has required, and will continue to require, significant investments in property, plant and equipment. As of December 31, 2010 and September 30, 2010, the carrying amount of property, plant and equipment, net was
$229.1 million and $228.9 million, respectively. We assess the recoverability of property, plant and equipment to be held and used by a comparison of the carrying amount of an asset or group of assets to the future net undiscounted cash
flows expected to be generated by the asset or group of assets. If such assets are considered impaired, the impairment recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets.

A prolonged general economic downturn and, specifically, a continued downturn in the battery cell industry as well as other market factors could intensify competitive pricing pressure, create an imbalance of industry supply and demand, or otherwise
diminish volumes or profits. Such events, combined with changes in interest rates, could adversely affect our estimates of future net cash flows to be generated by our long-lived assets. Consequently, it is possible that our future operating results
could be materially and adversely affected by additional impairment charges related to the recoverability of our long-lived assets.

We have not recognized any impairment charges for the long-lived assets for the three months ended December 31, 2010.

Inventory Obsolescence

We review our inventory for potential impairment on a quarterly or more frequent basis as deemed necessary. Such review includes, but is not limited to, reviewing the levels of inventory versus customer requirements and obsolescence. The review and
evaluation also considers the potential sale of impaired inventory at lower than market prices. At each balance sheet date, we identify inventories that are worth less than cost and write them down to their net realizable value and the difference is
charged to our cost of revenues of that period. Though management considers such write-down of inventories adequate and proper, changes in sales volumes due to unexpected economic or competitive conditions are among the factors that could materially
affect the adequacy of such write-down.

Allowance for Doubtful Accounts

The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our accounts receivable. We determine the allowance based on historical write-off experience, customer specific facts and economic conditions. Bad
debt expense is included in the general and administrative expenses. We review outstanding account balances individually for collectability. Account balances are charged off against the allowance after all means of collection have been exhausted and
the potential for recovery is considered remote. As of December 31, 2010 and September 30, 2010, we had not charged off any balances as we had yet to exhaust all means of collection.

Equity-Based Compensation

We adopted the provisions of ASC Topic 718 Compensation  Stock Compensation, which requires the use of the fair value method of accounting for share-based compensation. Under the fair value based method, compensation cost related
to employee stock options or similar equity instruments is measured at the grant date based on the value of the award and is
recognized over the service period, which is usually the vesting period. ASC Topic 718 also requires measurement of cost of a liability-classified award based on its current fair value. The fair value of the liability-classified award will be
subsequently re-measured at each reporting date through the settlement date. Change in fair value during the requisite service period will be recognized as compensation cost over that period.

15

---

We determine fair value using the Black-Scholes model. Under this model, certain assumptions, including the risk-free interest rate, the expected life of the options and the estimated fair value of our ordinary shares and the expected volatility,
are required to determine the fair value of the options. If different assumptions had been used, the fair value of the options would have been different from the amount we computed and recorded, which would have resulted in either an increase or
decrease in the compensation expense.

Pursuant to ASC Topic 718, we have recognized compensation costs of $525,000 in relation to stock-based awards to our employees and non-employee directors for the three months ended December 31, 2010, as an increase in both the operating costs
and shareholders equity.

Recently Issued Accounting Pronouncements

Please refer to note 1 to our financial statements, Principal Activities, Basis of Presentation and Organization  Recently Issued Accounting Standards, for a discussion of relevant pronouncements.

Exchange Rates

The financial records of Shenzhen BAK, BAK Electronics and BAK Tianjin are maintained in RMB. In order to prepare our financial statements, we have translated amounts in RMB into amounts in U.S. dollars. The amounts of our assets and liabilities on
our balance sheets are translated using the closing exchange rate as of the date of the balance sheet. Revenues, expenses, gains and losses are translated using the average exchange rate prevailing during the period covered by such financial
statements. Adjustments resulting from the translation, if any, are included in our cumulative other comprehensive income/(loss) in our stockholders equity section of our balance sheet. All other amounts that were originally booked in RMB and
translated into U.S. dollars were translated using the closing exchange rate on the date of recognition. Consequently, the exchange rates at which the amounts in those comparisons were computed varied from year to year.

The exchange rates used to translate amounts in RMB into U.S. dollars in connection with the preparation of our financial statements were as follows:

|                                                                                       |        | RMB per U.S. Dollar

|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We are exposed to interest rate risk primarily with respect to our short-term bank loans and long-term bank loans. Although the interest rates, which are based on the banks prime rates with respect to our short-term loans are fixed for the
terms of the loans, the terms are typically three to twelve months for short-term bank loans and interest rates are subject to change upon renewal. There were no material changes in interest rates for short-term bank loans renewed during the three
months ended December 31, 2010.

Please refer to Item 2, Managements Discussion and Analysis of Financial Condition and Results of Operations Liquidity and Capital Resources  Financing Activities for a discussion of our credit facilities and loan
agreements.

A hypothetical 1.0% increase in the annual interest rates for all of our credit facilities under which we had outstanding borrowings at December 31, 2010, would increase net loss before provision for income taxes by approximately $1.8 million,
or 46.9%, for the three months ended December 31, 2010.Management monitors the banks prime rates in
conjunction with our cash requirements to determine the appropriate level of debt balances relative to other sources of funds. We have not entered into any hedging transactions in an effort to reduce our exposure to interest rate risk.

Foreign Exchange Risk

Although our reporting currency is the U.S. dollar, the financial records of our operating subsidiaries are maintained in their local currency, the RMB, which is our functional currency. Approximately 98.3% of our revenues and 99.2% of our costs and
expenses for the three months ended December 31, 2010 are denominated in RMB, with the balance denominated in U.S. dollars. Approximately 99.3% of our assets except for cash were denominated in RMB as of December 31, 2010. As a result, we are
exposed to foreign exchange risk as our revenues and results of operations may be affected by fluctuations in the exchange rate between U.S. dollars and RMB. If the RMB depreciates against the U.S. dollar, the value of our RMB revenues, earnings and
assets as expressed in our U.S. dollar financial statements will decline. Assets and liabilities of our operating subsidiaries are translated into U.S. dollars at the exchange rate at the balance sheet date, their equity accounts are translated at
historical exchange rates, and their income and expenses items are translated using the average rate for the period. Any resulting exchange differences are recorded in accumulated other comprehensive income or loss. An average appreciation
(depreciation) of the RMB against the U.S. dollar of 5% would increase (decrease) our comprehensive income by $3.4 million based on our outstanding revenues, costs and expenses, assets, and liabilities denominated in RMB as of December 31, 2010.
As of December 31, 2010, our accumulated other comprehensive income was $30.1 million. We have not entered into any hedging transactions in an effort to reduce our exposure to foreign exchange risk.

Inflation Risk

Inflationary factors such as increases in the cost of our products and overhead costs may adversely affect our operating results. Although we do not believe that inflation has had a material impact on our financial position or results of operations
to date, a high rate of inflation in the future may have an adverse effect on our ability to maintain current levels of gross margin and selling and general and administrative expenses as a percentage of net revenues if the selling prices of our
products do not increase with these increased costs.

|ITEM 4. | CONTROLS AND PROCEDURES.
|------- | ------------------------

Disclosure Controls and Procedures

As required by Rule 13a-15 under the Exchange Act, our management has carried out an evaluation, with the participation and under the supervision of our chief executive officer and interim chief financial officer, of the effectiveness of the design
and operation of our disclosure controls and procedures as of December 31, 2010. Disclosure controls and procedures refer to controls and other procedures designed to ensure that information required to be disclosed in the reports we file or submit
under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to our management, including our chief executive
officer and interim chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no
matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating and implementing possible controls and procedures.

Management conducted its evaluation of disclosure controls and procedures under the supervision of our chief executive officer and our interim chief financial officer. Based upon, and as of the date of this evaluation, our chief executive officer
and interim chief financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2010.

Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting during our fiscal quarter ended December 31, 2010 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
