IBM UPS750TLV, UPS1500TLV, UPS1000TLV, UPS1000THV, UPS750THV, UPS1500THV manual On Battery Operation

Diagnostic Utility	The uninterruptible power supply has a diagnostic feature that displays the utility voltage.
Voltage	Plug the uninterruptible power supply into the utility power outlet.
	The uninterruptible power supply starts a self-test as part of this procedure. The
	self-test does not affect the voltage display.
	Press and hold the	button to view the utility voltage bar graph display. After a few
	seconds, this five-LED Battery Charge		display on the right of the front panel will
	show the utility input voltage.
	Refer to the figure at left for the voltage reading, corresponding to the configured nominal
	output voltage.
	The display indicates the voltage is between the displayed value on the list and the next
	higher value.
	If three LEDs are illuminated, the utility voltage is within the normal range. If no LEDs
	are illuminated and the uninterruptible power supply is plugged into a properly function-
	ing utility power outlet, the line voltage is extremely low. If all five LEDs are illuminated,
	the line voltage is extremely high and should be checked by an electrician.

On Battery Operation

The IBM uninterruptible power supply 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 uninterruptible power supply alarm. If the utility power does not return, the uninterruptible power supply continues to supply power to the connected equipment until the battery is fully discharged.

If you are not using PowerChute, shut down the operating system and turn off the computer before the uninterruptible power supply fully discharges the battery.

Determining On Battery Runtime

The uninterruptible power supply battery charges when connected to utility power. The battery charges to 90% capacity during the first three hours of normal operation. Do not expect full battery run capability during the initial charge period.
