I have a Dynamix 1800A UPS looking after a home machine. A sticker on the side reads :

That bit about "repeat the process" - I'm assuming that's meant to be read "repeat the process after having fully drained the UPS battery" ? It just seems a bit pointless otherwise as surely the battery is being topped up with charge as long as it's connected to the mains ?

haha, yeah so you're supposed to disconnect all the UPS load twice in the first 5 months of operation? Like that's going to happen.

The battery should indeed remain topped off. I suggest you ignore the label. UPS batteries usually need replacing every 3-4 years regardless.

edit: assuming they're lead acid batteries, no sense in draining them, they prefer to remain topped off.

I've never seen this on any other brand of UPS, though we stick to the 'better' brands like APC.

Just a heads-up re lesser-known UPS devices like the Dynamix ones. In my experience they are absolutely shocking at reporting a failing battery. In earlier times when visiting a new site I would run a self-test on the server's UPS. With the first three of the lesser-known-brand UPS devices I came across and did this with the server would lose power within the 10-30 second self test period.

As a consequence I now schedule this during a brief shutdown period, put the server into a pre-boot state go into BIOS for example) so it is consuming nearly full power and then kills the mains power to give it a real-world test without risking data corruption.

My Dynamix had another sticker that required the user to write down when they ran down their UPS at x monthly intervals...

It eventually sacrificed itself in a power surge: saved the computers but fried itself. When I move to the states I'll get a new UPS (they're much more affordable there), but it'll be an APC.
