[Nut-upsuser] APC ups reports "OL DISCHRG" as its normal status, even when plugged into mains

[Jim Klimov]

Adding to Greg's good questions, is the UPS (battery) new or old? Perhaps
the PbAc worked over ~3 years and indeed the UPS became a glorified power
strip? I had some BackUPSes do that every couple of years a decade to two
ago...

Hope this helps,
Jim Klimov
