Ultralife Batteries, Inc. Awarded $12 Million Army Battery Contract

Ultralife Batteries, Inc. (Nasdaq:ULBI) has been awarded a production contract for its BA-5390/U battery valued at approximately $12 million, by the U.S. Army Communications Electronics Command (CECOM). Battery shipments are expected to begin in the second quarter and be completed during the third quarter of this year.

John D. Kavazanjian, Ultralife's president and chief executive officer, said, "This order builds on the steady stream of BA-5390 battery contract awards that we received throughout 2003, and reinforces our ability to maintain volume production with a high level of manufacturing efficiency. It also reflects the continuing demand from the Army for the superior performance and cost effectiveness of our battery system."

This contract announcement is not related to the Next Gen II Phase IV, 5-year battery procurement for this and other rectangular military batteries, the solicitation for which was recently released by CECOM. Ultralife will participate in this procurement through the competitive bidding process, which is expected to begin in the first quarter of this year.

The BA-5390/U 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/U battery, the most widely used military battery in the U.S. Armed Forces. The BA-5390/U is widely used to power more than 50 military applications, such as the AN/PRC-119 SINCGARS (Single Channel Ground and Airborne Radio System) and the Javelin Medium Anti-Tank Missile Command Launch Unit. The BA-5390/U provides soldiers with the latest and best battery technology in a cost effective manner. More energy in each battery provides longer mission time with fewer batteries for soldiers to carry, and fewer batteries to ship and dispose of, all of which reduce cost to the Army.
