I've had my blackbook for a little over two years now and the battery is down to ~ 1 hour per charge and I would like to buy a new one before I get deployed. I'm gonna call Applecare tomorrow just to try to talk them into a new one (fat chance, i konw) but where should I buy the new battery? The ones on apple.com have lots of complaints, should I get one there or take a chance on e-bay? What's been your experiences?
