    Rating: 5/5 Breathe New Life into an Old Mac! September 17, 2017 Battery life on my 2008 MBP 15" was down to about 45 mins. This replacement gave my trusty MBP a new lease of life. Be sure to carefully follow the instructions relating to calibrating the battery. It's worth the time it takes to discharge, recharge, drain and recharge to get the most out of your new battery. I highly recommend this battery, and OWC!

    Rating: 5/5 Keeps on ticking March 23, 2017 My old MBP Late 2008 battery finally pooped out after some 8 years and I figured I want to wait for the 2017 update to the new MBP later this fall so replacing my battery was a no brainer and this replacement is working better than the original. Glad I got it.

    Rating: 5/5 Three years of abuse November 13, 2016 I've had mine for three years, and I didn't treat it very well. (Left it plugged in for weeks, or even months etc and general battery badness) and I'd say the battery held up quite well. It still works but only lasts a half hour or something, which is totally my fault. I'm about to order my second one...and this time I have a battery management app which will hopefully help me get a little more life out of it. I don't regret a thing though.... when it first came, I was amazed at how well it worked...and it did last longer than my original Apple battery did when the Macbook was new.

    Rating: 5/5 Great Upgrade! March 25, 2016 Upgraded my MacBook Pro with ram, battery, and an SSD. It has been sluggish for quite some time. Now it is very responsive and acts like it did when I purchased it new. The videos and how-to's made this upgrade very easy. Glad that I found MacSales & OWC.

    Rating: 5/5 Perfect replacement for my 5+ years old battery December 28, 2015 The trackpad on my late '08 MBP was giving trouble & I traced the trouble to a swollen 5 year old battery, which was otherwise ok! believe it or not.The new battery arrived as promised & fitted perfectly. My MBP is still fighting fit.

    Rating: 4/5 Don't get the *open box* version August 6, 2015 I originally ordered this open box, since it saved me about 20%. However neither the first one nor the second one OWC sent as a replacement worked in my late 2008 MBP. System profiler could see the battery, but it wouldn't charge. I even had the 2nd one tested at a local Apple dealer since it seemed weird to get 2 defective batteries in a row. In addition, the whole process took a few weeks because OWC won't cross ship replacement open box items. After receiving the 2nd defective open box battery, I decided to return it for refund and instead buy the same item new. Minus 1 star for the hassle, but I am happy with the new battery I eventually received. I get about 4 to 5 hours now per charge instead of 1 on the old one.

    Rating: 5/5 Great battery April 3, 2013 I haven't used this battery for very long, but so far it's working like a dream. I had a swollen macbook pro battery and didn't realize it. I eventually figured it out when my trackpad quit working and back cover wouldn't close. I can finally click my trackpad again. It might be my imagination, but it seems like my computer is running cooler and faster.
