Exhibit 31.2
              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 June 30, 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.

Dated:  August 19 , 2005                /s/ Guohua Wan
