I, Yongbin Han, certify that:

1.   I have reviewed this Amendment No. 1 to Annual Report on Form 10-KSB of
     China BAK Battery, Inc.;

2.   Based on my knowledge, this Amendment No. 1 to Annual Report does not
     contain any untrue statement of material fact or omit to state a material
     fact necessary to make the statements made, in light of the circumstances
     under which such statements were made, not misleading with respect to the
     period covered by this Amendment No. 1 to Annual Report;

3.   Based on my knowledge, the financial statements, and other financial
     information included in this Amendment No. 1 to Annual Report, fairly
     present in all material respects the financial condition, results of
     operations and cash flows of the registrant as of, and for, the periods
     presented in this Amendment No. 1 to Annual Report;

4.   The registrant's other certifying officer and I are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

     a)   designed such disclosure controls and procedures, or caused such
          disclosure controls and procedures to be designed under our
          supervision, to ensure that material information relating to the
          registrant, including its consolidated subsidiaries, is made known to
          me by others within those entities, particularly during the period in
          which this Amendment No. 1 to Annual Report is being prepared;

     b)   evaluated the effectiveness of the registrant's disclosure controls
          and procedures and presented in this Amendment No. 1 to Annual Report
          our conclusions about the effectiveness of the disclosure controls and
          procedures, as of the end of the period covered by this Amendment No.
          1 to Annual Report based on such evaluation; and

     c)   disclosed in this report any change in the registrant's internal
          control over financial reporting that occurred during the registrant's
          most recent fiscal year (the registrant's fourth fiscal quarter in the
          case of an annual report) that has materially affected, or is likely
          to materially affect, the registrant's internal control over financial
          reporting; and

5.   The registrant's other certifying officer and I have disclosed, based on
     our most recent evaluation of internal controls over financial reporting,
     to the registrant's auditors and the audit committee of the registrant's
     board of directors (or persons performing the equivalent functions):

     a)   all significant deficiencies and material weaknesses in the design or
          operation of internal controls over financial reporting that are
          reasonably likely to adversely affect the registrant's ability to
          record, process, summarize and report financial information; and

     b)   any fraud, whether or not material, that involves management or other
          employees who have a significant role in the registrant's internal
          controls over financial reporting.
