The bcmxcp driver reports directly what the UPS is telling us. If the  
algorithm used for battery charge calculation is voltage based (not  
entirely unlikely), small variations in the battery voltage may make  
it jump between two fixed values all the time. I have a very strong  
opinion about 'correcting' such behavior, since it can also be an  
indication of imminent battery failure.
