   Ultralife Batteries Receives $1.4 Million Production Order from
       General Dynamics for Land Warrior Batteries and Chargers

    NEWARK, N.Y.--(BUSINESS WIRE)--Jan. 12, 2006--Ultralife Batteries,
Inc. (NASDAQ: ULBI) has received a battery and charger production
order from General Dynamics C4 Systems valued at approximately $1.4
million. The contract is for lithium ion rechargeable batteries as
well as vehicle, bulk and individual Soldier-based chargers, part of
the equipment being delivered to General Dynamics for use in a Stryker
battalion operational assessment.
    Land Warrior is an integrated, modular fighting system that uses
technology to enhance individual soldiers' close-combat tactical
awareness, lethality and survivability. The system includes
weapon-mounted sensors, an integrated helmet assembly, a
communications-navigation computer system and software for
friendly-force tracking and command/control programs. Featuring
seamless connectivity to the General Dynamics Stryker combat vehicle,
the Land Warrior - Stryker Interoperable portion of the program will
undergo a comprehensive operational assessment and a Limited User Test
this summer.
    In February 2004, Ultralife received a $2.7 million development
contract from General Dynamics to design and develop the batteries and
chargers to equip Land Warrior ensembles with an advanced man-portable
power system. Deliveries against the new production order will begin
this month and be completed by the end of March.
    John D. Kavazanjian, Ultralife's president and chief executive
officer said, "Our power systems engineering services capabilities,
combined with our superb track record of developing and supplying
industry-leading battery and charger designs demonstrates our ability
to move highly-engineered products from design into production. These
capabilities are proving to be a key competitive advantage for us as
the demand for our products continues to grow."

Based Charger, which is a 3-battery rugged Smart Level-3 charger
mounted in different variants of the Stryker Vehicle; the CH0008
