Ok well i have a macbook a1278 macbook pro from 2009. Well I just upgraded ram to 8gb and now i wanna replace the battery since the battery life isnt up to par like it use to be. I was gonna have my friend who works as a geeksquad agent to order me one using his protection plan because he has the same macbook battery and he use to be able to order as many a/c adapter and batteries. But they finally caught on as a company and changed the parts order procedure. You now have to call in and they check your history. He's still trying to maybe get it for me, but if it doesnt work I have to just buy it myself. Im gonna ask my friends that work at apple store if they can get me a discount. Does anyone know how much of a discount they get on batteries? But if that doesnt pull through i might go on amazon/ebay. How are 3rd party batteries? Any site that has them for a reasonable price/cheap?
