              CERTIFICATION OF PRINCIPAL FINANCIAL OFFICER
                   PURSUANT TO RULES 13a-14 AND 15d-14
                  OF THE SECURITIES EXCHANGE ACT OF 1934

     I, Guohua Wan, Chief Financial Officer of Advanced Battery
Technologies, Inc. (the "Registrant"), certify that:

     1.      I have reviewed this quarterly report on Form 10-QSB for the
period ended March 31, 2005, of the Registrant.

     2.      Based on my knowledge, this report does not contain any untrue
statement of a 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 report.

     3.      Based on my knowledge, the financial statements, and other
financial information included in the 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 the report.

     4.      The 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)) and internal control over financial
reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the
Registrant and have:

             (a)     Designed such disclosure controls and procedures, or caused
such disclosure controls and procedures to be designed under my 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 report is being prepared;

             (b)     Evaluated the effectiveness of the Registrant's disclosure
controls and procedures and presented in this report our conclusions about the
effectiveness of the disclosure controls and procedures, as of the end of the
period covered by this 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 quarter (the Registrant's fourth fiscal quarter in the case
of an annual report) that has materially affected, or is reasonably 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 control over financial
reporting, to the Registrant's auditors and the audit committee of the
Registrant's board of directors (or persons fulfilling the equivalent function):

             (a)     All significant deficiencies and material weaknesses in the
design or operation of internal control over financial reporting which 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 control over financial reporting.
