Running a Manual or Scheduled Battery Test
Contents
Introduction
The UPS Network Management Card (NMC) allows administrators to validate UPS battery health through manual or scheduled tests. These tests ensure the battery can sustain the load during a power outage and help identify when replacements are needed before failures occur.Purpose
The purpose of running a battery test is to verify that the UPS batteries are functioning correctly and capable of supporting connected equipment in the event of a power failure. Manual tests allow end users to immediately confirm battery performance on demand, while scheduled tests provide automated, recurring checks that help detect battery degradation early. Together, these features ensure continuous reliability of the UPS and reduce the risk of unexpected downtime.Procedure
1. Running a Manual Battery Test:
Log into the UPS NMC Web GUI.
From the Home Icon, select Control & Manage.
Under the UPS tab, click the pencil icon next to UPS Manual Test.
Choose the test type:
Minimum – Quick functional test of the battery.
Timed – Runs the test for a user-defined duration (in minutes).
Full Discharge – Fully discharges the battery until it reaches low charge state. ⚠️ Use with caution, as this leaves the battery depleted until recharged.
If Timed Test is selected, enter the duration in minutes.
Click Save.
To start the test, go back to Control & Manage > Actions menu > Start Test.
Confirm when prompted. The test will begin and progress will be displayed in the GUI.
2. Cancelling a Manual Battery Test:
From the Actions menu, select Cancel Test.
Confirm when prompted.
3. Scheduling a Periodic Battery Test:
In the Web GUI, go to Control & Manage > UPS tab > Battery Test.
Select the option to Enable scheduled tests.
Enter the test interval in days (e.g., every 30 days).
Save settings. The UPS will automatically run a Minimum Test at the configured interval.
Troubleshooting
1. Test Fails to Start:
Verify the UPS is online and not already running a test.
Ensure no critical alarms are active (e.g., battery disconnected or fault).
2. Battery Test Aborts Early:
This may indicate weak or failing batteries. Review the UPS event log.
Run a Full Discharge Test to confirm battery capacity.
3. UPS Becomes Unavailable During Full Discharge Test:
This is expected — the UPS switches to battery power until depleted. Plan to run this test only during maintenance windows.
4. Scheduled Test Did Not Run:
Confirm scheduling was enabled and the interval was saved.
Check if the UPS was on bypass mode or shutdown at the scheduled time.
