Active stand-by storage
NOTE:
Due to a reduced risk of water depletion in the cells, this is the
preferred method of active standby.

Nickel-cadmium batteries automatically self-discharge at
approximately 0.25% per day at 68°F (20°C).
(1)
Saft vented cell batteries may be stored charged, ready for service in the

After 90 days the battery must be charged and the water level
checked in accordance with procedures found in TESTING and
FAULT ISOLATION.

shipped for long term storage.
