I have a 14" G3 iBook 700Mhz iBook which I love dearly.
However, the battery life is completely shot. It lasts about 20 minutes before pooching out. Any way I can fix this without having to buy a completely new battery? My bf mentioned something about Radio Shack rebuilding it. Is that safe? How much would it cost? Nothing seems to help, even draining it completely and recharging.
I brought my clamshell ibook's battery to a battery store when it died on me, hoping they would be able to rebuild it. The guy told me the cost of rebuilding it is just as much as getting a new one. So I decided then to open it up and see what's inside - the batteries used were special Sony batteries that couldn't be found in stores, so I doubt they could be rebuilt. I'm not so sure if that's the case with the newer iBooks like yours though.
Sadly, your battery is likely worn out. Mine did the same thing a year ago and the only cure was to get a new one.
I also learned that you should not fully discharge the battery every time it is used because that wears out the current technology faster. You do need to do full cycles the first couple times, but after that you should keep the laptop plugged in whenever you can. Each full cycle will cause irreversible damage to the chemical structure of the batteries.
