Testing a battery
Before you run a battery test, make sure that:
v The batteries are fully charged (the LCD displays the battery status message
Battery resting).
v The UPS is in Normal mode or High Efficiency mode with no active alarms.
v The load is greater than 10%.
v The bypass voltage is usable.
To test the battery, complete the following steps:
1. Connect the UPS to a power source for at least 48 hours to charge the
batteries.
2. While the main menu is displayed, press the down (
) button to scroll to the
Control menu, and press the OK button.
3. Press the down (
) button to scroll to Battery Test.
4. Press the OK button to view the Battery Test status.
Note: If the battery test is already scheduled or running, you can choose to
cancel the test. If the previous battery test failed or did not complete, see
Table 14 on page 58 for more information before scheduling another test.
5. If necessary, press the down (
) button to select Yes for Schedule battery
test.
6. Press the OK button to schedule the battery test for the next available test time.
During the battery test, the UPS discharges the batteries for 25% of the original
expected runtime. The front panel displays Battery test running and the
percentage of the test that is completed. The results are displayed on the front
panel when the test is completed.
