1. Battery runtime calibration
Last year, for an unknown reason, the battery runtime on one of my Schneider-APCUPS dropped the runtime to 1 minute and 7 seconds. Compared to my second UPS, I should have a runtime of about 45 minutes on each of my UPS.
My goal is to provide >30 minutes battery runtime for my IT hardware, so a runtime of 1 minute and 7 seconds on one of my UPS is not okay. To exclude any issues with the UPS or battery, I performed the suggested procedure by Schneider-APC as described in How do I perform a Battery Calibration on my Smart-UPS?
However, after two calibration attempts, the battery runtime stayed at about 1 minute. After getting in touch with Schneider-APC support, I received quite fast a replacement battery.
2. Battery replacement
Before the battery replacement I shut down all connected devices and disconnect the UPS from the Input power. Then I turn the UPS off on the LC Display. To remove the battery, the front bezel must be removed first.
The next step is to disconnect the battery plug.
This picture shows the disconnected battery plug.
There are six little screws which must to be removed.
Then the battery is removed. Attention: The battery is heavy.
In the next step the replacement battery is inserted. Attention: The battery is heavy.
Then the six litte screws are tightened again.
The battery plug must be reconected to the UPS.
The front bezel is inserted again.
After connecting the UPS back to it’s input power, the remaining runtime of the battery should be checked.
Also a self test after the battery replacement should be performed.
3. Setting battery replacement date
Because of the battery replacement the last replacement date should be set in the network management card. This can be done in the network management card at Configuration, UPS, Last Battery Replacement.
I would like to shout out a big thanks to Schneider-APC for the excellent, uncomplicated and fast support!
