Thank you everyone for sharing your experience and thoughts on my battery problem. Obviously after 3+ years I have just reached the end of my battery's life in my iBook 500. As a matter of fact, it has now gone from lasting one hour on full charge to only 37 minutes, so the downhill slope is getting steeper. Of all the responses, the following intrigued me the most. It seems that I don't have to replace my battery with the original part used on the iBook 500. I could even get the current G4 iBook battery and it should work. Has anyone tried getting the G4 12" Powerbook silver battery and changing the outer casing to the white casing??? Will it even fit?
