Local UPS. 500W. Used to run a couple of fans/lights. Working fine but exhibiting different behaviour.
Earlier, when it was charging -- the charge indicator came on and after it was charged fully, the charge indicator went off and the FULL indicator came on.
Now -- after it has charged fully, the charge indicator goes off and the FULL indicator comes on. BUT, after 2-3 seconds, it goes into a cycle. The FULL indicator goes off for a split second, the charge indicator comes on, battery charges (all in that second or so), then charge indicator goes off and FULL indicator comes on. Has been doing so continuously every 2-3 seconds. Don't know much about UPS's. Battery fluid level seems fine.
