Battery upgrade question

[mayakukla]

I bought mine in nov '09. There was a refresh with a higher capacity battery. Can i buy this on ebay and pop it in? I belive it takes it from 6 to 10hrs, correct? What is the apple part number so i can get an oem battey?

The built-in batteries are not user-replaceable.
