The storm last night performed a UPS test that was long over-due.

Unfortunately, the server UPS failed. One battery was 0V, and the other was 8.6V.

Both 7AH-12V batteries were replaced with new 9AH-12V batteries.

The old ones were the factory batteries, plut into service 2008-07-03 as per:

The UPS seems happy with the new batteries. They should provide a little longer run-time.

I’ll add a reminder to replace them in 5 years.
