Ultralife Corporation (NASDAQ: ULBI) has received orders valued at approximately $2 million from the U.S. Defense Department for its McDowell Research brand MRC-93 Ultimate Battery Eliminators for use by both the U.S. Army and Marine Corps. Deliveries are expected to be completed in the 2nd quarter of 2010.

The MRC-93 (National Stock Number 6130-01-520-8178) is a universal self-contained battery eliminator that connects directly to a radio transceiver replacing the battery box. It can connect to a wide variety of transceivers such as the popular AN/PRC-117F and AN/PRC-138 multiband manpack radios, among others. The MRC-93 operates worldwide, providing regulated DC power output from an external AC or DC power source, allowing for safe operation of DC powered equipment. This encompasses most AC generating systems on aircraft, ships and other power sources including solar, wind and diesel generators. The Eliminator also has the enhanced capability to use any available communications batteries as backup power should the unit lose AC or DC input power. These include Ultralife’s UBI-2590 lithium ion rechargeable and BA-5390 lithium-manganese dioxide non-rechargeable batteries, among other standard batteries available in the field.
