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 two minutes of runtime remain the UPS emits a continuous beep. If PowerChute or the Network Management Card is not being used, files must be manually saved and the computer must be properly shut down before the UPS fully discharges the battery.
The UPS battery life differs based on usage and environment.
Refer to the APC Web site, www.apc.com for on battery runtimes.
