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.
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.
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)
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.
