Ladies and Gentlemen:

You have requested our opinion with respect to certain matters in connection
with the filing by BOLDER Technologies Corporation (the "Company") of an
Amendment No. 1 to a Registration Statement on Form S-3 (the "Amended
Registration Statement") with the Securities and Exchange Commission covering
the registration of up to 4,400 shares of the Company's Common Stock, $.01 par
value (the "Shares") issued by the Company to the selling stockholder named in
the Amended Registration Statement (the "Selling Stockholder").

In connection with this opinion, we have examined the Amended Registration
Statement and related Prospectus, the Company's Certificate of Incorporation and
Bylaws, as amended to date, and such other documents, records, certificates,
memoranda and other instruments as we deem necessary as a basis for this
opinion. We have assumed the genuineness and authenticity of all documents
submitted to us as originals, the conformity to originals of all documents
submitted to us as copies thereof, and the due execution and delivery of all
documents where due execution and delivery are a prerequisite to the
effectiveness thereof.

On the basis of the foregoing, and in reliance thereon, we are of the opinion
that the Shares are validly issued, fully paid and nonassessable.

We consent to the filing of this opinion as an exhibit to the Amended
Registration Statement.

Very truly yours,

Cooley Godward LLP
