15" MacBook Pro (mid2010). I need to replace the battery.
I have inherited my deceased brother's 15" MacBook Pro (mid2010). The battery no longer keeps a charge, so it must stay plugged in. Can I change the battery myself? If so, must I use an apple battery to replace? Please advise.
MacBook Pro, OS X Mountain Lion (10.8.2), 2.53 Ghz intel core i5
