Description

The batteries in the UPS that backs my home network (and thus my servers, aside for Juno and two unmanaged Ethernet switches) have been suspect for a little bit now since the UPS started reporting an abnormally high load. What makes me suspect the batteries is that running a self-test typically clears this abnormal condition, and returns the UPS to a more sane state.

The batteries are the originals installed in 2021 when I originally purchased the UPS, so technically they are getting close to that time where they might need replacing.

Batteries have been purchased as of 2024-07-03 as it nearly failed its self-test.

Attempted to swap new cells in but was unable to as missing the tape to stick together.
