UPSes always seem to have strange failure modes. I've had a couple fail after a power failure. The batteries died and they wouldn't come back up automatically when the power came back. They didn't warn me about the dead battery until after...

That’s why they have self-tests. Learned that one the hard way myself.

My UPS was supposedly "self testing" itself periodically and it still happened!

Oof, sorry.
