before return from a shutdown.
Sensitivity
Normal
Reduced, Low
Set lower than normal sensitivity to avoid lowered battery
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 s hutdown at which the UPS issues a low
battery warning. Set higher than the default only if the OS

High Transfer Point
229
224, 234, 239
To avoid unnecessary battery usage, set the High Transfer
Point higher if the utility voltage is chronically high and the
load is known to work well under this condition.
Low Transfer Point
177
168, 172, 182
Set the Low Transfer Point lower if the utility voltage is
chronically low and the load can tolerate this condition.

Note:
UPS battery life differs based on usage and environment.
APC recommends that the battery/batteries be changed once every two years.
