Battery Care and Handling
The battery used in the GUPS 2400A-104 requires proper storage and recharging to maintain
reliability.
During storage, the self-discharge of the battery results in a sulfate coating that builds up on the
plates. This coating reduces the effective surface area of the plates which reduces the available
backup time. Allowing the batteries to self-discharge for too long may result in recharging
problems or in battery degradation.
Storing the battery at low temperatures reduces the level of chemical activity, thus sulphation
takes longer to occur. Reasonable storage times at different temperatures are listed in
Table 3

The batteries should be recharged for 72 hours after prolonged storage.
CAUTION!
Failure to recharge the batteries after the storage time may result in
permanent battery degradation.
