Ni-cads don't last forever.  I just had to replace the batteries in a
shaver; it was only two and a half years old.  Also, two other
characteristics of ni-cads may have made them unsuitable:

1) They discharge themselves after about three months if they're not
   Leave your computer off for that length of time and you'll lose
   whatever is protected by the battery.
2) If you don't completely discharge them between charges, the battery
   develops a "memory" so that it won't accept a full charge in the
   future.  (This is the probable cause of the dead shaver; you could
   prevent it by keeping it out of the charger until the thing needs a
   charge.)
