It could be that the UPS has performed an automatic battery test or  
runtime calibration in the mean time (which is not unusual for many  
higher end devices).

Note that in general, you'd be interested in changes in the trend,  
rather than absolute values. This not only counts for battery charge,  
but for most other readings as well. If there is a significant change  
in a value without you doing something, it's worth investigating what  
causes it.
