Ultra High Energy Rechargeable Battery (Army)
Abstract
Test a new rechargeable BB-2590/U battery. It consists of lithium-ion cells and replaces a battery used in many US Army portable radios and electronics equipment and is the most widely used battery in the Army inventory. Compared to the current production battery, the new BB-2590/U battery will have one hour (30 percent) greater service time, 1.6 Ah (24 percent) greater capacity, and 38 Watt-hours (20 percent) greater energy. At -32 °C and five amperes, the new battery will provide 1.3 hours service time and 165 Watt-hours energy; whereas, the current production battery will not operate at -32 °C. The battery weight will be reduced by 71 grams per battery. Less weight, greater run time, equals fewer batteries required for missions.
