Sealed leak-proof construction allows trouble-free and safe operation in any position. Batteries are built to withstand high levels of shock and vibration.
Low cell impedance allows the battery voltage to remain virtually constant for close to 90% of the discharge period delivering stable performance for a broad range of load requirements.
Life expectancy of Power-Sonic nickel-cadmium batteries is 500-1000 charge/discharge cycles, and five years or more when used in standby service at room temperature.
Resealable vents automatically control cell pressure and thus assure safety and reliability.
An operating temperature range of -20 ºC to +50 ºC (-4 ºF to 158 ºF) for regular cells, and -20 ºC (-4 ºF to 158 ºF) for hi-temp cells provides design flexibility for a wide band of environmental extremes. The temperature range for charging is 0 ºC to 50 ºC ( 32 ºF to 122 ºF)
Cell uniformity is assured through an electronic selection process which records capacity and impedance of each cell - an important feature in guaranteeing long term performance in cell assemblies.
