APC SURT 8000 xli fault code
Hello! I know this is not an information consumer should know, but my case is not trivial. What I have - an UPS out of warranty, few years it was just lied in a corner powered down.
Now I try to power it up. It started up with no loads seems ok. Then I connect input power, and it shows Fault led and error code is 01001 (upside-down). I connect a load to ups (about 1000 VA) and it beeps about low battery and keep it working online 5 minutes.
The nearest service is far away, I think the game is not worth the candle to transport it. So please could you say is this error could be fixed "in place" (say, by changing batteries to all new) or it requires complex diagnostics?
