10 About the Battery
1. Life of the battery depends on operating temperature and on the number of discharge
cycles.
2. “WHEN DOES THE BATTERY NEED REPLACING?”
If the BAT Led on the front of the UPS flashes 1x30sec and buzzer sounds, it implies that the
battery will no longer hold a full charge. Under this circumstances, if a power failure occurs,
the UPS runs less than half its normal length of time when compared to a good battery.
Perform the following steps to make sure the battery needs replacing:
1) make sure the UPS is plugged into a live wall outlet
2) charge the UPS for at least 8 hours
3) turn the UPS off and then back on
4) press ON switch to force a self-test
After step 4, if the BAT Led still flashes, there might be something wrong with the battery.
Since the battery will eventually wear out and needs to be replaced, please contact your
local dealer and ask for the battery replacement services
3. Extendability of battery is not possible in this UPS. Please do not add external battery to
the UPS. This will void the Warranty.
