Rating: 5/5 Product purchased worked out of the box December 11, 2016 I purchased my first MacBook Air in 2008(original one, Model A 1237) and kept it as part of my collection of Apple hardware. A few weeks ago, I noticed that the battery had swallowed and it died. So I wanted to replace it to keep my MacBook Air operational. I knew OWC for many years and went to their website to look for a new battery. Easy to find, a few clicks and the order was processed ! It only took 5 days for the product to be delivered at my house by UPS. I followed the video instructions of iFixit to open the Mac, extract the old battery and place the new one. I turned the unplugged Mac on, and it started as before. Very happy with this purchase !

Rating: 5/5 This Product is worth the $80! May 14, 2015 I had recently experienced some battery leaking on my mid 2011 Macbook Air. It was slowing down, and only retaining about 2-3 hours of battery life (instead of the expected 12.) At the time, I was also looking to upgrade my hard drive to the Aura Pro 6G 480GB (which is also amazing) and I thought I would look for batteries. I came across this beauty and I decided to take a chance and throw it in my beautiful aluminium chassis and see how it works. It was amazing, very long, full work day battery life, and it fit in my 2011 Macbook Air, as the battery size has not changed over the years. In conclusion, this is an amazing product.

Rating: 5/5 Revived an otherwise dead old laptop May 2, 2015 Brought my Gen 1 Macbook Air back to life as a usable piece of equipment. The battery had completely died and it was only usable while plugged into the wall. With the new battery, I get several hours of use out of it.

The kit came with all the tools needed and the overall install job from start to finish was under 20 minutes.

Rating: 4/5 Great product July 31, 2014 This was for my wife's 1,1 MacBook Air, which she has used almost every day from the day it was born. The original battery lasted till this year when it began losing capacity and I didn't want to spend what I figured Apple would charge.

OWC's installation video explained everything, and I got good, live (chat) tech support when I had a small problem (I hadn't got the internal power connector snapped all the way in). Easier than replacing the disk in this machine which I did last year with an OWC SSD. Run time completely restored after battery replacement.

Overall, 5 stars, EXCEPT new battery seemed to be slightly - as in .001" - larger than the original so going back together everything was really, really tight, including the power connector mentioned above. My guess is the one I got was right at the upper tolerance for size. Minus 1 star for that, & I'm not the first reviewer to mention.

Rating: 4/5 Not Perfect June 11, 2014 I'm always leery of purchasing 3rd party aftermarket batteries for my Mac laptops. I decided to give this one a try because I have found OWC to be an excellent Company offering superior products. The install was a little difficult in that the tolerances on a MacBook Air are very tight and this replacement battery didn't fit as smoothly as the OEM battery. However, I was able to get the battery installed satisfactorily. The problem was the replacement battery may be just a little thicker in width which complicated reinstalling the bottom plate. With some patience however, I was able to get everything back together correctly. As far as performance the battery seems to work well and has extended the time I can work on the Air without attaching the charger. Overall I am satisfied and hope the battery lasts 500 or 600 charge cycles which has been my experience with OEM batteries.

I would recommend this item to a friend!
