Right, so I never received a response. I know I can get a new base, but I really only want the battery as a base will add extra bulk to the unit.

@ajb2k3 I haven't, but just did!

My Core2 battery wasn't charging, so I opened it up and saw the battery or all puffy, usually indicating it's broken.

I've looked around but can't find a battery that matches, does anyone know of one?
