Rating: 5/5 Totally Awesome! November 29, 2021 OWC made it so easy with their video. I had no problem with the entire process. The best part is the life extension it gave my old 2012 MacBook Air! Saved me from having to spend $1-2k on a new laptop. I am thankful they had the right part. I wouldn’t hesitate to buy from them again and would certainly recommend them to any Mac user!

I would recommend this item to a friend!

Rating: 5/5 New Battery, Mobile MacBook Air Back on the Road Again November 25, 2021 The original, aging (from 2012) battery got about an hour of use, maybe. It had over 600 charge cycles out of 1000. Thought I could still keep it going. But, the 2012 MacBook Air was showing signs of swelling around the case. Went to MacSales (OWC) to get a replacement. Where else can one get new parts for a nine-year-old notebook? Put in the new battery which was easy from their video. Got it all charged up with charge cycle number one. It is a good feeling that my favorite notebook can be used for a very long, long time.

Rating: 5/5 Two weeks, so far, so good… June 26, 2021 I use my laptop mostly docked, closed and attached to an external monitor. I opened it a few weeks ago and noticed the keyboard was bowed. Hmm. Wonder what’s going on there? A little google foo later and I discovered I had a very swollen battery! OWC to the rescue.

OWC shipped quickly. The replacement battery for my 2015 MacBook Air arrived well packed and in short order.

Installation was a breeze. It was so easy in fact, I opened it back up after to install a larger Apple SSD after replacing the battery - it’s super easy just pay attention to where the different length screws go and don’t over tighten. I did use my iFixit pentlobe and torx kit instead of the included tools. The included tools were adequate, but the other tools I used are magnetized and easier to use.

After the battery replacement I followed the fully charge, charge an extra few hours, fully drain and recharge procedure. This apparently calibrates the battery (see instructions for full details).

Since replacing this a few weeks ago my poor MacBook and its new battery are working perfectly. Hopefully this battery has a good service life, but after the short time I’ve had it, I’m very pleased.

Response from OWC, Support June 28, 2021 We are so happy to be there to save the day and your MacBook Air!

Rating: 4/5 Easily Replaced April 27, 2021 Purchasing this battery and having my computer guru friend install it worked out very well. I just thought the new battery would last longer as I use the MacBook. I find I have to charge it after an hour. Not sure if it is due to the sites I use.

Reviewer: ShyWoodchuck-69926
Rating: 3/5 No better than old battery April 23, 2021 The battery arrived as promised and it was very easy to remove the old battery and install the new one in my MacBook Air. However, the performance of the new battery is not much better than the old one. I still need to recharge the battery before the day is over when all I'm doing is reviewing emails, reading online news, etc. I don't do any heavy duty computing or watch videos. Seems like I should have stuck with the old battery.

Response from OWC, Support May 21, 2021 NuPower batteries are designed to meet and exceed factory specifications and we are sorry to hear that you have not seen much of a performance increase. We would be happy to speak with you further and make sure your battery functioning properly! Please email us at support@owc.com, we look forward to hearing from you.

Rating: 5/5 The Rebirth December 7, 2020 I am so happy that I was able to give my 11 inch 2012 MacBook Air life without its lifeline again. This is the second battery that I have purchased for this computer. The first battery was a bargain battery purchased from Amazon that never truly performed well. Initially I was getting two hours worth of use out of it that eventually dwindled to less than an hour within 30 charging cycles. What a waste of money! Anywho, I regathered my senses and went back to what I knew best from my previous Mac purchases. OWC has always provided the best of my Mac needs. The purchase of this NewerTech NuPower battery just proved that theory even more. I installed the battery and did the initial suggested charge cycle and the battery have been pure bliss ever since. I haven't recharged it yet since installation two days ago and I'm still at 48% battery life. A lot of it would probably have to do with the OWC Aura 6G 480GB SSD that I installed a few years ago. Who Knows! All I know is that it is once again Awesome in All Ways! Thank You OWC
