Rating: 2/5 Not impressed March 20, 2020 I purchased this battery just over 2 years ago. Installation was fine. It seemed to fit well. I was overall happy, until about 3 months ago. The battery swelled up so much the track pad on my laptop became unclickable. I understand batteries are not permanent pieces. But under 2 years for a laptop battery is not by any measure a great life. Especially considering the inconvenience of having to install/remove the part. I was hoping after my hard drive upgrade and battery replacement that I'd never need to open my unibody macbook pro again. Guess that was too much to hope for

Rating: 5/5 You get what you pay for....so get this! December 20, 2019 I originally purchased a "Genuine OEM" battery for my 2011 15" MacBook Pro off eBay for $40. Thought it was a really great deal if it was genuine. Turns out, it was not genuine. Also, it would not hold a charge for more than about 5 minutes after fully charging. I returned it and got by money back, then decided to spend more money for a NuPower Aftermarket Battery! This Battery is 1000x better! Battery performs just like the original one did when it was new! Don't go the cheap way out by getting a "too good to be true" price on eBay. Buy this one instead and don't look back!

Rating: 3/5 meh October 8, 2019 I bought this to replace an Apple OEM replacement battery that was badly swollen (the touchpad couldn't be clicked) after about 2 years.

My first disappointment was that the tri-Y driver provided was the wrong size for the battery hold-down screws. Really, OWC, how hard is it to get this right?

Second observation was that the battery arrived stone dead -- 0% charge -- so the "power-up and see if it starts" test of proper installation didn't succeed. I had to use AC power to get things going. Aside from being an annoyance, this makes me wonder how long this unit had been sitting on the shelf in a fully discharged state, and how that may have affected its life expectancy.

So, overall, this experience was less than I'd expect from OWC. Only time will tell how the battery lasts. Given the poor performance of the Apple battery, this may be the only game in town.

Rating: 5/5 Works as promised July 20, 2019 While "Works as promised" may not seem like high praise, it actually is. My mid-2012 began to suffer with random shutdown syndrome when my original battery hit the 5 year mark. When I decided to replace it I went to a reputable shop in Canada and bought what appeared to be a genuine Apple replacement. But although it looked like the real deal, it caused my laptop to shut down 2 or 3 times per day. I returned 3 batteries because of this, and that's when I decided to try the NewerTech NuPower battery. I've had zero issues, its capacity is 7307mAh compared to the original's 7200mAh. It just works, as promised. No more random shutdown issues, and my laptop has a second life. Thank you.

Rating: 5/5 Expensive but looks reliable April 9, 2019 Macbook Pro 2012 2.6ghz with GT650m I've spent 200$ CDN on this, and this is really the most expensive battery I've ever bought. In light browsing, 5h of juice at my 7th cycle. Performance looks good but with the dgpu ON, it dies in less than 1 hour... more apple's fault than the battery. Reviews are good all over the place. I hope it will stay good for a 1000 cycles.

Rating: 5/5 Don't cheap out! February 11, 2019 My MacBook Pro battery needed to be replaced and I initially ordered an inexpensive battery from Amazon. After installing it, my Mac would intermittently shut off, so I removed it and returned it for a replacement. The replacement had the same problem, so I returned it for a refund. Time is money and you'd think I would have learned that by now. Having to take the time to pack something up and drop it off to be shipped takes time not including the labor in installing and removing the battery twice.

The battery I received from OWC is working great. I should have ordered from OWC from the start and saved myself the time it took to install and return two faulty cheap batteries to Amazon.

Rating: 5/5 The Best Replacement Battery for my MBP 15 October 21, 2018 Tried other lower cost batteries sold on eBay that did not measure up to the quality and capacity of this battery. I have been using my MacBook Pro 15 now a couple weeks since the install with over 3 charge/discharge cycles and it is still at 102% health and lasts longer than the original Apple battery it replaced. I highly recommend it. It may cost you a bit more, but it is definitely worth the extra investment. Great value and piece of mind knowing that you can install it and go...no hassle or worry over quick battery drain like the other knockoffs out there at lower costs. Buy it and you won't be disappointed.

Rating: 5/5 The only game in town August 21, 2018 I recently bought this replacement battery for a 2012 macbook pro, but only after I first bought the budget battery from Amazon. Five days later, after calibration and smc reset, I had learned my lesson when the budget battery was only lasting 40 mins on a full charge with light web browsing. OWC is really the only game in town for replacement batteries if you want to get performance equal to the original OEM battery.

Rating: 5/5 Charging June 24, 2018 Seems to be working just fine. Calibrated it according to directions provided and all seems well. Was a little disappointed that I received an open box item but apparently clearance items are just that. Watch what you click on. I guess I wasn't paying that good of attention. It came with 0% charge instead of 30% so I was concerned, called about it and was assured it was ok. Box and battery were all sealed. It is working great

Rating: 5/5 Trust OWC! April 19, 2018 I bought 2 batteries off of eBay from a seller who was selling "OEM" batteries for about $45 (Check for yourself, theres lots of sellers). Compared to OWC's $99, I thought it was a steal. I'm a firm believer in "you get what you pay for" but seeing that "OEM" buzzword plastered all over the ad gave me that gooey, warm, happy peace of mind feeling. Long story short, the batteries I purchased were crap. The seller/ company did have excellent customer support, I'll give them that, but their product sucked. The batteries took about 5hrs to fully charge and would only last about 3hrs tops. Not to mention the battery would drop from 40% to 7% instantly. BOTH BATTERIES!

So I went back to OWC, bought this battery you're reading the review for. I should have done that from the get-go. I was a little worried when I took the battery out of its packaging because the build quality felt exactly like those eBay batteries... cheap plastic, nothing like the battery that initially came with my MBP, sorry OWC. This battery I purchased performs on par with the original battery, maybe better. I strongly recommend this product!

Rating: 5/5 Easy install and works better than original December 19, 2017 My daughter's 2011 15" Macbook Pro stopped booting as the battery was no longer chargeable. Ordered the NewerTech NuPower 77.5 Wh battery to replace the original Apple battery. Great that they include screwdrivers to remove the bottom plate and the actual battery pack. That went very easy and installing the new battery was easy except for a problem screwing back in the last screw. I had to loosen all the screws and pull the battery as far as possible to align the holes in the Macbook and the battery pack. Then I put the back plate back on and charged the new battery fully. It was a relief to see the battery charging. After draining the battery and recharging and then resetting the SMC the battery now shows about 4.5 hours of usage which my daughter thinks is more than the original usage.
