Ok, so my [correct] output is below.  Is there a way to disable a  
battery?  It's really more just so I can get the correct output from KDE's  
battery monitor.  It currently recognizes the two batteries, and when I  
have the AC adapter unplugged it shows 50% (I'm assuming because one  
battery is full, the other empty -- or unrecognized -- rather than 100%).
