      Some have self tests options. If you have a small one, just unplug it and see if the battery holds at all. If it’s dead it will die really quick.

        Yup! I got some cyberpower ones from costco. Wrote a script to test and send me the results first saturday of each month. If it fails, there goes my saturday lol.

        Sometimes they get into a state that requires a hard reset. Happened to me a few times and was losing power during brownouts. Learned to test regularly after that.

      I haven’t used a UPS in like 25 years. Don’t they have battery life indicators now? If not, that seems pretty useless.
