Very Quick iBook Battery Question

[ChrisFromCanada]

I have a very quick question about ibook batteries. I just ordered the new G4 ibook. I want a second battery and I have found some apple batteries "Model #: A1008 LI-ION 10.8V" I am betting these are batteries for G3 ibooks but will they be compatible with my new G4 and are there any differences between the G3 and G4 batteries?

FWIW, my brand new iBook G4 12" has a model no. A1061 10.8V battery.

The original battery in my G3 iBook is a model M8403 10.8V battery. However, Apple no longer sells that part number, and claims (correctly, as I've found) that the modern A1061 works fine in a G3 iBook. Now, whether an old iBook battery will work in a new iBook I don't have any way to judge (since my wife's new G4 iBook is a 14" and my G3 is a 12"). However, I strongly suspect that the only difference is whether the plastic is brilliant white or antique white (or whatever they called the color of the older iBooks).

Okay so I need a 10.8V battery and model number A1061 is what I need but it is expensive and I need to find out if A1008 is compatable. Does anyone out there know?

Thanks for your help...
