   I've run into a related battery problem with a decade old Macbook.   
      
   I just replaced the battery with a noname.   
      
   It works fine, and gives me a couple of hours of run time   
   (not sure how it compares to the "real" ones, but it's adequate).   
      
   HOWEVER, some of the programs (that's you, Firefox) are running   
   a lot slower.   
      
   Why?   
      
   I ran some diagnostics and pulled up the logs via Terminal,   
   and discovered a huge chunk of error messages that were   
   apparently generated by the operating system trying to   
   talk to the battery.  And these were displaying with   
   the "previous message repeated 100 times" line.   
      
   It looked like it was enough to mess things up.   
      
   Afraid I don't have the laptop here so can't quote it   
   exactly, but when I did a deep Duck search, some other   
   people suggested it was a battery deal.   
      
   Sure enough, when I slapped in my old battery (it still   
   works, but only for 15 minutes...) those messages vanished.
