Apple thinks constant recycling if not as good as leaving it alone and 
using the external  P/S.   On mine if it's below 95% it charges to 99% + 
and then disconnects the battery and stays disconnected 'till the level 
drops below 95% from using w/ o the charger.  It recommends occasionally 
discharging the batt. 'till the computer detects it's dangerously low 
and goes to sleep.  Then one plugs in the supply 'till it's fully 
charged.  This resets the charge level detector.

bc, who still has a charger w/ an auto discharge function for thos oldies.
