Optimized Extreme-Environment Performance Specially engineered for operations in freezing climates, this high-performance battery operates reliably in temperature ranges from -40°C to +55°C. It features instantaneous start-up capability, ensuring that mission-critical equipment remains operational in the most demanding cold-weather conditions without delay.
Versatile Dual-Mode Power Architecture The BB-2590/U provides a flexible energy solution with a dual-output design. It delivers 19.8Ah in 14.4V mode or 9.9Ah in 28.8V mode, catering to a wide variety of hardware power requirements. With a typical energy capacity of 285Wh, it provides long-lasting power for high-drain applications.
Intelligent State-of-Charge Monitoring To provide operators with real-time energy data, the unit is equipped with two independent 5-segment LCD "gas gauges". These displays provide a constant, absolute state-of-charge readout for each battery section, ensuring precision power management during active deployments.
Mission-Critical Ruggedness and Safety Designed in accordance with standard MIL-PRF-32383, the battery is housed in a durable, high-impact resistant plastic enclosure. Its reliability is further enhanced by an all-welded construction, hermetically sealed cells, and integrated safety venting to protect against short circuits and improper charging.
Comprehensive Platform Compatibility Utilizing a standard 6-pin polarized socket (SC-C-179495), this battery serves as a high-performance replacement for numerous models, including the BB-590/U, BB-390B/U, and BA-5390/U. It is the ideal power source for EOD robots, surveillance sensors, and tactical manpack radios such as the SINCGARS (AN/PRC-119) and FALCON (AN/PRC-117) series.
