Running Battery Tests
Automatic battery tests run approximately every 30 days, unless
disabled. During the test, the UPS transfers to Battery mode and
discharges the batteries for 25 seconds under the existing load.
NOTE The “UPS on Battery” notice and the “Battery Low” alarm do not activate during a
battery test.
For an automatic battery test to run:
S
The “Automatic Battery Support Tests” setting must be enabled.
S
The UPS must be in Normal mode, with no active alarms.
S
The batteries must be fully charged.
S
The bypass voltage must be acceptable.
S
No manual battery test was initiated previously in the same charging
cycle.
For a manual battery test to run:
S
The UPS must be in Normal mode, with no active alarms.
S
The bypass voltage must be acceptable.
To run a manual battery test:
1. Press any button to activate the menu options.
2. Select CONTROL then START BATTERY TEST.
During the battery test, the UPS transfers to Battery mode and
discharges the batteries for 25 seconds. The front panel displays
“Battery test running” and the percentage of the test completed.
During the battery test, the UPS monitors the battery voltage constantly.
If the expected total discharge time is greater than 15 minutes, the
battery voltage should remain above 1.83 volts per cell (VPC) during the
test. If the expected total discharge time is less than or equal to
15 minutes, the threshold is 1.81 VPC.
To pass the battery test, the battery voltage must remain above the
threshold value during discharge.
If the battery voltage drops below the threshold, the UPS returns to
Normal mode and the front panel displays “Battery Test Failed.”
