And into the early iMacs. On some of the first iMacs the battery would 
only last a year or 2, and the machine would not boot when it failed, 
leaving one to go scrambling to source an oddball battery. Seemed to 
last longer in later versions. Today I might find an alternative 
solution rather than buy a new battery, but early iMacs are one machine 
it could be a little awkward to fit an alternative.
