            Ultralife Batteries, Inc. Announces Multi-Million Dollar
         9-Volt Battery Private Label Order and Annual Contract Renewal

Newark, New York - (July 28, 2003) - Ultralife Batteries, Inc. (NASDAQ: ULBI)
today announced a multi-million dollar order and annual contract renewal to
continue supplying its advanced 9-volt lithium battery under private label for
an existing major consumer battery-brand customer. Regularly scheduled
deliveries against the new order are expected to occur throughout the next 12
months.

John D. Kavazanjian, Ultralife's president and chief executive officer, said,
"This new order, and renewal of our private label contract with a long-standing
Ultralife customer, following our recently announced order from another major
consumer brand company, demonstrates the strong demand for, and greatly
increasing reach of our long-lasting 9-volt lithium battery."

Nancy C. Naigle, Ultralife's vice president of sales and marketing, said, "This
contract to continue supplying our 9-volt battery under a major consumer brand
label will help to support our expansion of this product into both existing and
new markets." . Ultralife's 9-volt lithium battery is a consumer-replaceable
battery that lasts up to five times longer than alkaline 9-volt batteries and up
to 10 times longer than carbon-zinc (general purpose) batteries. This primary
(non-rechargeable) battery has the highest energy density, flattest discharge
voltage curve, longest shelf life, widest operating temperature range, and
lightest weight of any comparable-sized 9-volt battery. The battery provides the
longest life in commercial and consumer applications including medical, wireless
security, safety, music, and industrial products.
