No luck calibrating SU2200I after battery exchange

Anonymous user · ‎2021-06-29

Hello, I tried to run the UPS (SU2200I) after battery exchange at approx half load (900W) on battery till it turned itself off, unfortunatelly it still kept the old settings. The battery leds are gone in a while, and the UPS runs most of the time thinking that it is almost empty (1 last battery led blinking) and beeping constantly. It is very annoying.

How to perforn the calibration correctly? Or is there some button or jumper inside that can be pushed/shorted so that the UPS resets itself?

There is a way to reset the calibration using a terminal program like putty or hyperterminal.

You are going to have to search. I have the procedure for a different smart UPS. Because it is not the same model as yours, I can't post it.

If not done correctly, you can render your UPS completely non-operational.

The information you seek is available.
