On Battery Operation

The UPS switches to battery operation automatically if the utility power fails. While running On Battery, an alarm beeps four times every 30 seconds.

Press the button to silence this alarm. If the utility power does not return, the UPS continues to supply power to the connected equipment until the battery is fully discharged.

When 2 minutes of run time remain, the UPS emits a continuous beeping. If PowerChute is not being used, files must be manually saved and the computer must be turned off before the UPS fully discharges the battery.

Refer to www.apc.com for information on battery runtimes. The UPS battery runtime differs based on usage and environment.
