My UPS has an LCD that says the battery is 100% and the estimated run time is 12min. The uspc has similar results. The problem is when line power is lost the UPS batter goes to 0% very quickly (seconds). It charged to 85% when power was restored. 86-100% is slower. I did: $ upscmd desktop_ups test.battery.start.deep Username (admin): Password: OK Now the ups.test.result says there is a warning. I suspect this will tell me the error. $ upsc desktop_ups ups.test.result Done and warning How do I get more details about the result? Surely there must be more. Are the symptoms consistent with a failed battery? It is old.

It is old.Yes, these are typical symptoms of an old battery no longer capable of holding charge. Roger

It is possible that there is more information that hasn't been mapped to a NUT variable in upsc, but there really isn't a lot of other standard information to convey. Some UPSes will report a status that we map to the "RB" (replace battery) flag in ups.status.> Are the symptoms consistent with a failed battery? > It is old.Lead-acid batteries are good for about 2-5 years in an UPS.> > _______________________________________________ > Nut-upsuser mailing list > Nut-upsuser at alioth-lists.debian.net > https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
