   Ultralife Batteries Receives $1.6 Million Military Battery Order

    NEWARK, N.Y.--(BUSINESS WIRE)--Feb. 1, 2006--Ultralife Batteries,
Inc. (NASDAQ: ULBI) has received an order valued at approximately $1.6
million from the U.S. Defense Department for its non-rechargeable
lithium-manganese dioxide BA-5347 military batteries. The company
expects to begin deliveries in the first quarter and complete them in
the second quarter.
    The order represents the first production release under a
five-year contract awarded to Ultralife in February 2005 by the U.S.
Defense Department. The contract could reach a maximum value of $15
million, representing 60 percent of a small business set-aside award.
    "Because of the extensive usage of infrared thermal sights by the
U.S. Military, the demand for the BA-5347 battery has been
increasing," said John D. Kavazanjian, Ultralife's president and chief
executive officer. "Ultralife has been the established producer of the
D-size cells used in BA-5347 batteries for the last few years and we
are pleased that we will now be building and supplying the entire
higher-value battery."
    The BA-5347/U is an 11.1 ampere-hour, 6-volt battery used to power
the advanced AN/PAS-13 infrared thermal weapon sight. More than 25,000
sights have been fielded by the U.S. Armed Forces.
