So, I recently procured a MB 2gHzC2D. It had a dead battery. Being a late '06 MacBook, it falls into the batch of bad batteries that Apple got. I called Apple and the support guy basically said I was screwed. Then I told the support guy about this web page: Here's a quote:
If Apple or an AASP determines that your battery is eligible for replacement, you will receive a new battery, free of charge, even if your MacBook or MacBook Pro is out of warranty.

The page even shows that 300 cycle count. After I pointed that out, the support guy sent me over to a tech guy who said I was right. Now they're air mailing me a new battery for free. ;D
