BATTERY LIFE
The batteries in your Staco UPS system were shipped from the factory fully charged. If
you plan to place the batteries in storage for any period of time prior to installation and
startup then the following precaution should be followed.
Batteries placed in storage will age. How fast they will age depends on the storage
temperature. The batteries are rated for storage over a temperature range of -15
o
C to
40
o
C (5
o
F to 104
o
F). The amount of time the batteries may be stored without recharge
varies greatly with storage temperature. Please consult the following table. If the
batteries are allowed to sit in storage for an excessive period of time before recharging
then they are subject to irreversible damage.
Once the batteries are placed into service and fully charged, the useful life of the
batteries will be reduced if they are subjected to high temperatures. The operating
temperature range of -15
o
C to 40
o
C (5
o
F to 104
o
F) must not be exceeded for even
short periods of time. Batteries operating continuously at or near 40
o
C will experience
a shorter useful life than batteries operating continuously at 25
o
C. Battery life will be
further shortened if the batteries are allowed to fully discharge and then left in that
condition for extended periods of time. As soon as the load is removed from the battery
it will continue to age at a higher rate than a fully charged battery. The longer the
battery remains discharged the greater the risk of irreversible damage.
Allowing the batteries to become damaged due to; a) operation or storage outside
the rated temperature range, b) storage for extended periods of time without
recharge per the table above, or c) sitting for a period of time in a discharged
state will void the battery warranty.
