A few days ago my wife's indigo clamshell developed some real strangeness regarding battery charging. We have 10.2.8 on it. The battery is a BTI replacement battery. She had the machine plugged in to recharge, and the charge indicator ring switched from amber to green, but charge was frozen at 82%. I tried running it down for a while, got down to 62% and plugged it back in. It charged for a few minutes, back up to 63%, and then swiched from amber to green and froze at 63%. Tried resetting the power management button and nothing changed. Figured we try running the machine to no charge--well, the battery wasn't recharging but certainly could hold a charge. After a couple of hours we needed to go to sleep, and the machine was still at around 13%, so we put it to sleep and finished running it down the next day. Plugged it back in, the ring switched to amber, and then after a few minutes switch back to green. Started the machine up and the charge was frozen at 1%. Unplugged the machine and it ran for 10 minutes or so and then conked out.
The adapter is obviously fine because the machine runs fine on the adapter. The battery appears able to hold a charge--after all, it started having problems at 83% and took hours to run down. Anything to do about this other than just buy a new battery--the machine is out of all applicable warranties.
Wtf?

My Wife's Blueberry is having similar touble. We've have one BTI replacement battery go phut, and yesterday the repalcement started acting up. It would not wake up and when plugged in and showed 0% when it woke up. After being plugged in all day, its showing 2%.
I've tried the NVRAM reset trick in Open Firemware, but that doesn't seem to make a difference.
I don't know if the iBook charging circuit is going wrong, or its the BTI battery which has died. If I'd kept the receipt I might talk to BTI about it.
