I know this about ni-cads, what I ment was why didn't apple choose to use 
a rechargable battery ( there are better alternatives to ni-cads ) this 
would have made the battery at least last the ten years or more.  Anyway,
Anything would have been better than soldering a battery to the mother
board!  A replacable watch type battery would have been better than this!
