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.
