Ultralife Batteries, Inc. Receives $2.2 Million U.S. Army Battery Order

    NEWARK, N.Y.--(BUSINESS WIRE)--Nov. 22, 2004--Ultralife Batteries,
Inc. (NASDAQ: ULBI) has received an order valued at approximately $2.2
million from the U.S. Defense Department for its BA-5372/U military
battery. The order represents another release under Ultralife's Next
Gen II Small Cylindrical battery contract. Deliveries against the new
release are expected to begin by the end of 2005.
    John D. Kavazanjian, Ultralife's president and chief executive
officer, said, "We have been supplying this important battery under a
number of contracts for 10 years and have increased production due to
its sustained high demand. This latest order illustrates the strength
of the overall demand for military batteries, since the BA-5372 is
used in the same radio systems as our BA-5390 battery."
    NextGen II is the U.S. Army's five-year battery procurement
strategy. Phase II of this program included production contracts
awarded to provide three types of primary (non-rechargeable)
lithium-manganese dioxide batteries. The three battery types -
BA-5372/U, BA-5367/U and BA-5368/U - comprise the Small Cylindrical
Cell Lithium Manganese Dioxide Battery Group. A major objective of
this five-year procurement strategy is to establish and maintain a
domestic production base of a sufficient capacity to timely meet
peacetime demands and have the ability to surge quickly to meet
deployment demands.
    The BA-5372/U battery is used for memory backup primarily for the
AN/PRC-119 MANPACK Single Channel Ground and Airborne Radio System
(SINCGARS), and in numerous other applications including encryption
and cryptographic devices, and the Patriot Missile System.
