Did they check the cycles? Back then the batteries were only rated for 300 cycles so if you were above that they wouldn’t exchange it. Apple did exchange the battery in my MacBook Pro (2007) three or four times or so (I had Apple Care, so warranty for three years) because I had similar problems you had – but each time my battery was below 300 cycles. As far as I know that is official Apple policy. I never had to convince or smooth talk anyone, they just exchanged in, no questions asked. And I didn’t exchange the battery always in the same place, once or twice over telephone, at an Apple Authorised Service Provider, at an Apple Store.
