replacement battery for dual-usb iBook

Message #1 - Posted 2003/12/09 - BreadWithSpam

So my 2+ year old dual USB iBook doesn't hold that much of a charge anymore.

Sleeping overnight, it's down to like 50% the next day.

And actually working off the battery, I'd be very lucky to get most of an hour.

I'm told that this isn't surprising for a 2+ year old LiIon battery. Not a big deal.

So I'm looking at getting a new battery (much as I'd like to pick up a new G4 iBook or even a 15"pBook...).

Apple's own battery seems to be $129 and readily available.

I've only found one alternative - BTI (Battery Technology) makes one and Amazon's got that listed at $116.09.

Now, I don't mind paying a little more or less if one or the other is actually better. Does anyone know? Are they really identical?

Want to try my tricke calibration battery rejuvenation? What's your capacity? Try:

ioreg -p IODeviceTree -n battery -w0 | grep Bat
