We recently introduced the most advanced Li-CFx battery technology for portable power applications. The first two batteries, EP-XX90 and EP-X590 are for portable military communications equipment, specifically SINCGARS, as an alternative to BA-5590, BA-5390, and BB-2590. Additional configurations will be introduced for other military and industrial applications.


Batteries using Li-CFx are unpressurized systems and are considered very stable compared to other lithium-based structures. The EP-XX90 and EP-X590 have been tested against the Army’s Mil-0PRF-49471B battery specifications and have passed UN Transportation testing. EaglePicher is committed to meeting the increasing energy demands for Soldier portable power.
