That is bad. In that case we need the output of

     /path/to/usbhid-ups -DD -a upsname

Note that I want exactly *two* debug flags here. Not more, not less.  
You'll want to stop all parts of NUT, fire up the above command and  
leave that running for about thirty seconds. Then kill the driver with  
ctrl-C and post the results here, so we can have a look what is going  
on.

No, that's the job of the UPS.

It's the HID path 'UPS.PowerSummary.WarningCapacityLimit' as read by  
NUT. If you're interested in finding out what it means, I suggest the  
USB HID Power Device Class specifications. These are available online  
(Google is your friend).
