BacUPS XS1000G Battery not charging

This was originally posted on APC forums on 3/7/2016


The battery icon on the front of unit is not showing.  I never got a "replace battery" message. But the battery remains at "0%".  It was at 100% no more than a few weeks ago.  Only noticed it was at "0%" during a recent power outage.  Using on a Mac so I can't use software.  Anything I can do?  Or do I need a new battery.

Thank you,

CK

If the unit is three years or older, it might be time for a new battery. Battery lifetimes varies depending upon the power quality in your area.

A good way to test the battery is to use a non-critical load such as a lamp. Turn the unit on, load it to about 30% of its capacity and pull the UPS plug from the wall outlet. If the battery is good, the UPS should hold this load for several minutes. This will result in additional wear on the battery, though you will be sure of its condition after this test.

I've had one of these units get out of calibration, so much so that it always displayed an empty battery icon even though the batteries were good and it was charging. The fix, which might involve temporary use of another computer, was to use PowerChute to indicate that I'd replaced the battery. apcupsd is cross platform software (not sure how well it works on Mac OS X) that could do the same, if you're comfortable with using the Terminal.

You could also try what is called a "braindead". Disconnect all loads from the UPS, turn it off, unplug it from the wall and remove the battery pack. With the battery pack out of the unit, press and hold the power button for a few seconds. Don't be surprised if the unit squeals or tries to power up. That's normal. Wait a bit longer and put the battery back in. Then hook everything up as it was.
