8 . B A T T E R Y
The battery is the only UPS component which is not in permanent use. It has a useful life of
approximately 3 to 5 years. However, frequent major discharges or exposure to temperatures
over 20 C will shorten its life span. We therefore recommend that users recharge the battery
once every 3 months when the unit is not in use in order to compensate for natural discharging.
UPS backup time will depend on the powered load, as well as the age and condition of the
batteries.
WARNING!
Batteries should always be replaced by qualified technicians. Batteries have a very high
short circuit current: connection errors could cause electric arcs resulting in serious
burns.
