  Ultralife Batteries, Inc. Receives $3.1 Million Contract from the US Military
                    to Expand Battery Production Capability

     - Additional Equipment Positions Ultralife to More Than Double BA-5390
                       Battery Manufacturing Capability -

Newark, New York - September 24, 2003 - Ultralife Batteries, Inc. (NASDAQ: ULBI)
has signed a contract with the U.S. Department of the Army - Communications and
Electronics Command (CECOM) whereby Ultralife will receive $3.1 million to
purchase on behalf of CECOM, manufacturing equipment to expand the company's
BA-5390 lithium-manganese dioxide battery manufacturing capability at its
Newark, New York factory. The company expects to complete the equipment purchase
and installation by February 2004.

After completing the equipment installation, Ultralife expects to have the
capability to produce revenue of more than $9 million per month of its BA-5390
batteries as new orders are received. This capability represents more than
double the company's BA-5390 manufacturing capability during the second quarter
of 2003.

"Ultralife is pursuing a diverse set of long-term growth opportunities, one of
which is to capitalize on the US military's conversion from lithium-sulfur
dioxide to lithium-manganese dioxide batteries," said John Kavazanjian,
Ultralife's president and chief executive officer. "The addition of this
equipment positions Ultralife for a new level of production readiness to meet
the military's growing demand for BA-5390 batteries."

Joseph N. Barrella, Ultralife's senior vice president of new business
development, added, "We are extremely pleased to support the military's
increasing demand for high-energy, long-lasting lithium-manganese dioxide
batteries. According to CECOM, the US military has an urgent need for Ultralife
to increase its production capability for our BA-5390 batteries. We believe this
equipment contract underscores the US military's recognition of the superior
performance and high quality of our batteries and strengthens our company's
position as the major supplier of this much needed battery."

The BA-5390 is a lithium-manganese dioxide primary (non-rechargeable) battery,
and with 50 percent more energy, is an alternative to the lithium-sulfur dioxide
BA-5590 battery, the most widely used military battery in the US Armed Forces.
The BA-5390 is widely used to power more than 50 military applications and
provides soldiers with the latest and best battery technology in a cost
effective manner.
