I have a Back-UPS CS 500 attached to a Linux PC (openSUSE 13.1 x86_64) that since this morning reports

BCHARGE  : 000.0 Percent
TIMELEFT :   0.0 Minutes

The other values seem normal to me:

Is this maybe some firmware bug? The value "000.0" seems really odd...


Update

Now the battery seems to have recharged a bit, but it seems stuck at 14%:

No, this is normal behavior.

Your battery dates from 2010 and it simply died. A battery expectancy date for a UPS is typically about 5 to 6 years.

Your battery needs replacement. I'm not familiar with this type of UPS, so I don't know if they sell replacement batteries or that you need to replace the whole unit. If replacing the battery is possible, it will be cheaper.

  • Generally, APC are pretty good about replacement batteries. – a CVn Jun 16 '16 at 11:08
  • Yeah, I didn't noticed it was an APC. – LPChip Jun 16 '16 at 14:18
