MILITARY 6T BATTERYA123’s light-weight, long-lasting, high performance 6T batteries are engineered to meet the specific, demanding requirements of military vehicles. The 6T is designed as a drop-in lead acid replacement for engine start and silent watch applications. The 6T battery leverages the systems engineering and manufacturing utilized in the commercial production of A123’s 12V Engine Start Battery.

The 6T is available in 12V and 24V models.

Primary Applications:

SILENT WATCH

�� Provides long-duration usable energy for powering vehicle systems in an engine-off mode

�� Communicates state of charge (SOC) and state of health (SOH) information for maximum battery utilization

ENGINE START

�� Form fit to allow drop-in replacement for 6T lead acid batteries currently deployed in military vehicles

�� Optimized 12V or 24V power net system for improved fuel economy (allows for vehicle to disable alternator under certain conditions)

�� Greater usable energy enables more start cycles

SOLDIER POWER

�� Man portable power solutions

�� Unmanned aerial and underwater vehicles

�� Unmanned ground systems and portable power

Longer Life

Designed to deliver significantly longer cycle life than lead acid resulting in lower total cost of ownership.

Greater Charge Acceptance Rate

Rapid charge capable, no recovery period required after previous charge or discharge and significantly higher rate capability than lead acid.

Lighter Weight

Approximately 50% lighter than lead acid batteries of equivalent capacity.

Intelligent Battery Management System

On-board calculation of state of charge (SOC), state of health (SOH), diagnostics and precise current and voltage measurements.

Excellent Safety

A123’s Nanophosphate® chemistry provides excellent abuse tolerance and multiple layers of protection that are employed at the chemistry, cell and system level.

Advanced Temperature Control

Integrated battery heater for operation at temperatures below –30 °C (available in next-generation versions).
