    My MBA Rev A's 37WH battery is dying and since I need to replace it I was thinking about buying the bigger 40WH battery from the MBA Rev C to eek out a little more juice. Has anyone already been able to figure out if this will work?

    It should work. I don't see any differences in the plug or screw positions

    Thanks for the response!....Before I posted this thread I called a couple of third party Mac service shops and they said it could not be done. I wonder if this was just a standard response.

    I can't answer for service providers. Honestly, I'm not 100% sure. Theoretically, if all the screws are in the right position and the plug is the same, theres no reason why it shouldn't work.

    There was speculation that SMC update for older MBA's released soon after revision C added compatibility for new battery, so they'd be able to use new batteries for replacements when they run out of original ones - it would make sense since it'd be cheaper for Apple to order more of one part, not two different ones. Of course we won't know for sure until someone tries it (or gets a new battery as a replacement).

    Well the Rev. B and C machines are essentially the same.

    bumping an old thread

    has anyone actually tried this? I've got a rev b, and I'd like to get as much battery life as possible. If it does work, anyone know where I can order a rev c battery?

    I'm interested in this too. Also, what is a good place to order a new battery in Canada? If I get one from Ebay, what should I look for?

    Purchased a used 40Whr apple battery from ebay. Installed fine and works so far on my early rev A. 31 cycle count used battery, seller had a picture of the apple logo and 40wHr label.
