5.4 Replacing the Battery
Timing of battery replacement
CAUTION
Damage
Replace the batteries periodically.
Continued use of a UPS at the end of its battery life
may result in battery leakage or smoking.
The battery has reached the end of its useful life in the following cases.
When the BATTERY CONDITION LED (orange) on the front of the
UPS lights up and a warning sounds.
When the backup time of the battery has been lowered to 3 minutes or
less (at the rated load)
Battery life is greatly affected by ambient temperature and connected
device conditions; if the UPS is used under standard environmental
conditions (ambient temperature 25°C, rated load), the battery should be
replaced after approximately three years.
