  Ultralife Batteries Awarded Contract Worth Approximately $7 Million By U.K.
                              Ministry of Defence

     NEWARK, N.Y.--(BUSINESS WIRE)--March 14, 2007--Ultralife Batteries, Inc.
(NASDAQ: ULBI) has received a contract valued at approximately $7 million to
supply BA-5590 lithium-sulfur dioxide batteries to the U.K. Ministry of Defence.
Ultralife will provide the MoD with batteries manufactured by EaglePicher
Technologies, LLC through a supply agreement. Deliveries are expected to begin
this quarter and be completed in the fourth quarter.

     "This very significant contract offers clear evidence of the depth of
Ultralife's international selling capabilities," said John D. Kavazanjian,
Ultralife's president and chief executive officer. "While we already supply our
industry-leading lithium-manganese dioxide BA-5390 batteries to the MoD, we
recognize that our customers sometimes require alternatives. In this case our
ability to win this contract by sourcing through EaglePicher represents a major
achievement in unseating an incumbent supplier and demonstrates our flexibility
in supplying our customers with the products they require."

     "All of us at EaglePicher Technologies are thrilled that Ultralife has
selected our 5590 battery as part of this significant win," said Steve Westfall,
President, EaglePicher Technologies, LLC. "It is an example of how we are
growing our business. As a supplier, our goal is to make this relationship
seamless and transparent with quality products delivered on schedule."
