Rating: 5/5 Great battery for my 2012 11” MacBook Air August 19, 2018 My Air is 6 years old and the battery longevity was just over an hour with under moderate use. I just bought a new 13” Air and hadn’t figured out what to do with the 11”? My daughters 10 year old MacBook Pro I bought her for college finally had an issue with the keyboard having several keys fail. It had been a great laptop through college for her and afterwards, but it was time to retire it. She always liked the size of the 11” Air and she thought about buying one, but was disappointed when I told her they had discontinued the 11”. This was a good time to pass on my 11” because she will hold onto it until it fails. I wanted to replace the battery before giving it to her, so I looked on line and read reviews. Poor fit and heat we’re mentioned in some reviews. I knew an OWC replacement would by high quality and a trusted replacement. Battery installed easily with the included tools and after conditioning the new battery it was ready to be passed on. She loves the 11” and I know it will faithfully serve her for several more years. Thanks Mac Sales...

Rating: 5/5 Perfect July 23, 2018 As always, this battery fits perfectly, takes a charge smoothly and has good discharge time. Ironically, the battery that I replaced, which I think also came from MacSales, is probably OK. It was charging and discharging erratically. After I got this new battery, the erratic performance resumed, and my testing discovered that it is almost 100% sure that there is a fault in the low-voltage cable of the MagSafe Power supply, which also came from MacSales**. I found an intermittent hot spot in the wire. This most probably came from damage in use. I have a replacement wire on order. In the past, I have had faulty MagSafe shoes, and successfully spliced in new wires to recover the use of the power supply units. ================================ **Brand: Apple OWC Item #: APLMB283LLA Order #: 107-1681213-3649013 placed on March 6, 2014

Rating: 5/5 New Life for Old Mac July 11, 2018 Easy to install with tools provided. Had to search a bit for the install video but once I had access to that install was easy. My little 11” MacAir has a new lease on life. Battery charge lasts all day with intermittent usage versus prior original battery that might let me work unplugged for an hour or two.

Rating: 5/5 Easy Instructions - Easy Installation April 5, 2018 Apple told me that my 6-year old MacAir could not be serviced by them since it was 'vintage." It only needed a new battery and MacSales made the process easy. I had a problem with the first battery not charging correctly and Customer Service shipped a new one ASAP. Very happy.

Rating: 5/5 Saved my bacon February 12, 2018 Apple wanted my 11" Air for FIVE DAYS and would charge $129 for a 20-minute battery change service. I hunted online to find out whether one could change the battery oneself and sho nuf, you guys were the winners. The battery is wonderful; Spousenik put it in very quickly AND the replacement came with its own Torx screwdriver. Way to go, guys! Have already recommended this to two of my children with battery issues.

Rating: 5/5 Quick and easy installation February 8, 2018 The battery comes with everything you need to easily install it into your Macbook Air. In addition, it comes with some helpful pointers on how to calibrate the new battery to get the most life out of it. I thought that was a nice touch. The battery fit perfectly and seems to have the same life as I remember the Air having when it was new in 2011.

Rating: 5/5 Never buy batteries from non-trusted brands July 28, 2017 I had to change my OEM battery, and chose a very poor "high grade reviewed" replacement. This one was back ordered for months. I got burned, I left the laptop in the car overnight around 30 degrees. Yes my neglect, but I have never suffered a complete malfunction in one wrong doing. Apple's OEM is a high grade, therefore can take the fluctuations of temps. I've done several battery replacements, and it's better to recommend this one for the continuity of product quality. I have some photos posted to show the performance reports. I've rendered a screen capture of what is running in the background to get a better deal of power consumption.

Rating: 5/5 Fantastic upgrade July 8, 2017 Kudos to MacSales for a great product :-) Easy to install, great directions from MacSales. My "NewerTech NuPower 39 Watt-Hour Replacement Battery" for my 2012 11" MacBook Air has exceed all my expectations. After 41 charges, over 7 months, the capacity has increased to 5325 mAh - from 5267 mAh. Significantly more than the stock Apple battery maximum capacity. I've used the FruitJuice battery app to recommend charging cycles - to a great result.

Rating: 5/5 Love the new battery on my Mac Air 11 June 1, 2017 First of all, I love the product I received. The NewerTech battery on my Mac Air 11 made it work just like new. I get up to 8 hours battery life and can go through the entire day working on my laptop without any issues.

Secondly I wanted to give a shout out to MacSales customer support team. I haven't had such a delightful customer service experience from any other vendor besides Amazon. Please keep up the great service and needless to say customers like myself will always keep coming back.

Thank you!

Rating: 5/5 My old MacBook Air could barely hold a charge February 14, 2017 My 2012 MacBook Aire would last anywhere from 1-1.5 hours per charge. I had a charger in the office and at home, sometimes carried it with me. With the new battery, I was getting battery life better than when it was new. No more carrying my charger, and I only have to plug in at night when I'm home.

Rating: 5/5 Direct replacement and perfect fit. November 8, 2016 Although this battery is made up of only 4 cells vs. the 6 cells of the original Mac battery, the 4 cells are much larger and equal the same mAh as intended. This was a direct fit for my swollen battery that managed to swell up all 6 cells, bending the keyboard upwards and swelling the bottom, which made it rock like a rocking chair, w/o all 4 rubber feet ever able to touch my desktop surface.

Took me only 5 minutes to unfasten the back, unscrew the battery from the chassis, unplug the battery and replace. Works great and was way cheaper than the deductible Apple was charging despite still being under Apple Care (will never pay for that garbage again). Would definitely recommend anyone who needs a new battery.

Rating: 5/5 Battery Works Great! May 26, 2016 It's only been 3 months but the battery is working as promised! Installation was super easy and battery came with a about half a charge which was nice. I'm a student and I get about 6-7 hours on a full charge with mostly internet and Google doc work. I still bring my charger with me just in case I want to kill time on Youtube or Netflix . Happy I took a chance with MacSales.com as it was a straightforward, inexpensive choice compared to other independent retailers and the Apple Store. It should be noted Apple's warranty on a new battery was 90 days, not 1 year like MacSales. Glad I went for it:)
