6. Storage
All lead acid batteries self-discharge in open circuit. The result is that the voltage of open
circuit is decreased, and the capacity also decreased. During storage please note:
The self-discharge rate is related with ambient temperature. The self-discharge degree is
smaller when the ambient temperature is lower, otherwise is larger. The requirement
temperature of FAAM FLL batteries’ storage environment is from 0
°
C
to 35
°
C
. The
storage place must be clean, ventilated and dry.
An important parameter in storage is open circuit voltage, which is related with density of the
electrolyte. In order to avoid perpetual damage to the plate caused by self-discharge, the
batteries should be supplemental charged if they have been stored for three months. The
equalized charge method should be adopted.
During storage, if the open circuit voltage is lower than 2.10V/Cell, the batteries should be
supplemental charged before use. The equalized charge method should be adopted.
All batteries, which are ready to store, should be fully charged before storage. It’s suggested
record the storage time in the periodic maintenance record and record the time when another
necessary supplemental charge should be made.
The quality certificates of FAAM FLL batteries record the latest charge time of
the batteries, the next charge time can be calculated according to this charge
time.
