Video: How do I adjust Battery Test settings ​on my Symmetra PX 250-500 UPS

How to adjust Battery Test settings

Product line:
Symmetra PX 250/500

All Product models, all serial numbers

Business needs may require on-demand self test initiation, or adjustment to self-test scheduling.


The battery self-test is used to periodically and automatically test the health of the battery modules in your UPS system. It is an important tool to detect failing batteries and to ensure they receive proper attention.  Battery self-test can be run with a frequency of every week to once a year (typical settings are bi-weekly or monthly).  Your site conditions and UPS load are typical considerations when choosing your battery self-test interval.

The runtime calibration is a manually initiated procedure that helps report the reduced runtime available as batteries age.  This test is not run automatically, as each test is a significant drain on the batteries.  Besides site condition and UPS load, battery age is also an important factor in deciding if and when to run a runtime calibration. At most this test should be run once a year.

Begin at the home screen of the UPS.

Press the wrench key at the lower left of the screen.

Press the ‘Configuration’ button.

Press the ‘User Configuration’ button.

Enter the user password (apc by default)

Press ‘Battery Test Settings’

Your battery charge must be at least 50% for a battery self test, 100% for a runtime calibration.  When finished reading, hit the back arrow at the top left of the screen

Tap Start to begin the battery runtime calibration or self test. You can tap Cancel to stop the calibration. The status of the runtime calibration is shown under Runtime calibration status
