Ultralife Batteries Awarded $9 Million Contract for System Integration
                Kits to Support Military Communications

    NEWARK, N.Y.--(BUSINESS WIRE)--Oct. 31, 2006--Ultralife Batteries,
Inc. (NASDAQ: ULBI) through its McDowell Research unit, has been
awarded a contract valued at approximately $9 million from a major
U.S. defense contractor for the production and delivery of Integration
Kits supporting military communications systems for installation on
military vehicles. Deliveries are expected to begin this quarter and
be completed in the second quarter of 2007.

    "Both Ultralife and McDowell share a philosophy of delivering
value to customers through the integration of proven products into
complete power systems and a commitment to continue employing this
approach to enlarge our presence in the growing prime contractor
segment of the military market," said John Kavazanjian, Ultralife's
president and chief executive officer. "In this case, we were awarded
the contract because of the breadth of our core product offerings, our
past performance, and responsiveness in supplying these types of
systems to both prime contractors and directly to the military. As a
result, Ultralife is now further diversifying its military business
and strengthening its ties to existing customers who place a premium
on engineering expertise and high performance power systems."

    The Integration Kits consist of a combination of McDowell's
MIK-21-75 Vehicle Kit and its MRC-195 Communication Case. The
MIK-21-75 is designed as a permanent installation on High Mobility
Multipurpose Wheeled Vehicles (HMMWV) while the MRC-195 is a
transportable case system to allow for the movement of the system to
areas of interest. The integration kits will enable the U.S. Military
to conduct secure broadband communications, including satellite
communications, from wheeled vehicles.
