capacity and service life in situations where the load can

tolerate minor power disturbances.

Duration of Low Battery Warning 2 minutes 5, 7, 10 minutes Sets the time before shutdown at which the UPS issues a low

battery warning. Set higher than the default only if the OS

UPS battery life differs based on usage and environment.

APC recommends that the battery/batteries be changed once every two years.
