I had over 9500 cycles on my iBook G4 before I finally replaced the battery. I bought the computer in March of 2004, and I replaced the battery in August 2008. I got a whopping 21 minutes of life on a full charge. It was heaven when I plugged in the new one and got 5:21 on it!!!!!!!

Thats 5+ cycles a day...what the hell were you doing?
