Tadiran Batteries has announced the release of its TLM-1550HP high-power lithium AA-size battery, which has five key characteristics. First, it delivers 2W-hours of energy with an open circuit voltage of 4.0V and is capable of handling pulses of up to 15A, and 5A maximum continuous current at 3.2V. Secondly, the cells have instantaneous voltage response after prolonged storage: they provide up to 20 years of service life. Third, these cells are safe, rugged and capable of withstanding extreme temperatures from -40 to +85°C. The cell design features a glass-to-metal hermetical seal instead of a less reliable crimped elastomer gasket. Fourth, the battery can be periodically tested, enabling system readiness to be confirmed without fully discharging the battery. The fifth distinction is its flexibility: It can be easily combined in series or parallel to create custom battery packs in virtually any shape or size. Smaller cells, including sub-1/2 AA and 2/3 AA sizes (with 15mm diameter) are now available. As the battery is lighter and smaller than other batteries, it leaves more room for the payload of sensors, cameras and portable communications equipment.
