APC 2200XLT, 3000T, 5000T, 1400XLT User Configuration Items, How to Determine On-Battery Run Time

User Configuration Items

Note: Setting these items requires optional software or hardware.

Function	Factory Default	User Selectable Choices	Description
Automatic Self-Test	Every 14 days	Every 7 days (168 hours), On	Sets the interval at which the UPS will execute a self-test.
	(336 hours)	Startup Only, No Self-Test
UPS ID	UPS_IDEN	Up to eight characters to define	Use this field to uniquely identify the UPS for network
		the UPS.	management purposes.
Date of Last Battery Replacement	Manufacture Date	Date of Battery Replacement	Reset this date on battery replacement.
Minimum Capacity Before Return from	0 percent	15, 50, 90 percent	The UPS will charge its batteries to the specified percentage
Shutdown			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
			needs the time for graceful shutdown.
Alarm Delay After Line Fail	5 second delay	30 second delay, At Low	To avoid alarms for minor power glitches, set the alarm delay.
		Battery Condition, No Alarm
Shutdown Delay	20 seconds	180, 300, 600 seconds	Sets the interval between when the UPS receives a shutdown
			command and when shutdown occurs.
Synchronized Turn-on Delay	0 seconds	60, 180, 300 seconds	To avoid branch circuit overload, the UPS will wait the
			specified time after the return of utility power before turn-on.
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.

How to Determine On-Battery Run Time

Note:

UPS battery life differs based on usage and environment.

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