Rating: 5/5 So far, so good July 31, 2014 The battery replaces the original in my MacBookPro 5,4. I was a little reluctant to change it myself, because, according to Apple, it is not "user-replaceable". Nevertheless, I did it. The video supplied by OWC is perfect. It told me everything I needed to know. The tools that I needed were included with the battery. I have only had it for two days now, so I can't judge reliability, but I can say that installling it was, as OWC would say, "straightforward".

I would recommend this item to a friend! This review is from NewerTech NuPower 78 Watt-Hour Replacement Battery for MacBook Pro 15" Unibody (Mid 2009 - Mid 2010).
