Rating: 5/5 4 years still going August 4, 2018 Late review, but probably more useful. I am on my 4th year with the replacement and even now the battery status is still good. It has lasted longer than several cel phone batteries at this point. Scoop one up, and keep that old MBP going!

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 Great replacement battery! January 7, 2018 This is the second battery I've ordered from OWC to keep my aging MBP running happily. I live in a hot, humid tropical climate that causes early death for many laptop batteries. I'm so glad they keep this model in stock for our older laptops! I run mine hard and heavy and it still keeps up with my demands.

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.

Rating: 5/5 Renewed my MacBook Pro November 18, 2017 It was an easy install, a seamless startup, and is working great now. The package came with the two screw drivers necessary to remove the cover and the battery screws. It also provided a link to information about how to cycle the charge on the new battery to give it full charging capacity and to sync it with the laptop.

Rating: 5/5 Replaced an expanding/exploding battery October 15, 2017 Noticed my MB Pro was looking warped and the lid wasn't flush. Found that the battery was expanding and pushing the case to be misshapen. Ordered the Newer tech battery. Easy to install with included tools. Worked like a charm. Follow the instructions to condition the battery.

Rating: 5/5 New battery has put new life into my Macbook Pro.. September 12, 2017 I knew my battery was failing. It has been pretty much in constant use for over 6 years, and was starting to cause power related issues. Put in a new replacement from OWC, and it is acting like a new Macbook Pro again. That isn't the only thing I replaced, but it is one of the most important. My 6 year old battery was down to 87%, which is enough to cause some things to hiccup. Never anything that killed the computer, but enough of an issue to warrant more restarts than normal. All good again.

Rating: 5/5 Just what the doctor ordered!!! September 3, 2017 I could not be happier with this battery. My 2011 Macbook Pro wasnt lasting 30 minutes on a supposed 100% charge so I figured I got my monies worth out of the original battery. I considered taking it to Apple but for the cost Macsales was a much better deal I ordered the battery it arrived in a few days just as promised. The install took 5 minutes tops then I proceeded to run through the calibration process which took a day and a half but I was able to use the laptop the entire time. Now the laptop lasts for hours just like when it was new. I would recommend OWC's batteries to anyone its a cost effective repair well worth it.

Rating: 5/5 Yes, you can restore your old MacBook! August 27, 2017 I didn't realize my 2011 laptop had a burst battery until I had already bought a replacement computer. When I opened the case of my bloated old Mac, it was obvious it could be salvaged. Thanks to the Newertech NuPower replacement, I now have a repurposed unit for sale on eBay in near perfect condition.

Rating: 5/5 Good as OEM August 17, 2017 This is my second replacement battery for my MacBook. The first replacement I bought a cheaper "uBatteries" third party battery from Amazon. It was junk!!! Freshly installed, it would only provide enough power for a couple hours and quickly deteriorated until it had to be plugged in constantly. This Newertech battery behaves just like I remember the original Apple battery. I can depend on it providing power for a good while. It's really easy to install too – screwdrivers are included. It's really worth spending a little more on this battery than other options.

Rating: 5/5 Great Product Easy to Install July 18, 2017 Really nice battery was easy to install by watching the videos on the Mac Sales site. It was well packed and well made its seems to work great and fixed the processor cycling problems I was experiencing from trying to use a MacBook Pro with a zonked battery. Now my computer works GREAT!

PS It was nice that they included the two screwdrivers in the box!

Rating: 5/5 Great replacement Battery May 17, 2017 Don't waste your time on Amazon or ebay because I bought a batter on each of those sites only to realize that I wasted my money buying junk that barely lasted an hour. This new battery from OWC has restored my 2011 MBP to being able to use my mac for 3 - 5 hours depending on use.

I will only buy replacement items from OWC in the future. Thanks.

Rating: 5/5 Great installation video/customer support! May 2, 2017 I was a bit nervous, even though installation of a new battery is supposed to be "straightforward" and reasonably easy. The new battery came with the necessary tools, a card listing the steps to follow -- and a computer link to a short, excellent installation video. All this relieved this first-time newbie's concerns, and my installation went without a hitch. The video (which you can pause anywhere along the way as necessary) took me smoothly through all the steps (including a reminder that some of the screws on the back of my MacBook Pro are longer than others, and need to go back correctly) and included instructions on how to correctly calibrate the new battery (and explained why this very important step can't be skipped). I'm very, very impressed at how user-friendly MacSales/OWC made the whole process. They also gave plenty of specifics about the new battery itself -- and instructions on what to do if I had any issues whatsoever with the battery. But so far I'm very impressed by the battery's quality and durability. (It was also easy to find the right battery on the customer-order site. The order process was smooth and direct. This company makes everything easy, from start to finish.)

Rating: 5/5 Works well April 19, 2017 I installed this in my Macbook Pro from 2012. I've only been using it for a few weeks but so far it's working perfectly and has greatly improved the time I can work before I need to recharge. One thing to be aware of -- you'll need to condition the new battery, but OWC includes instructions for that. Overall, OWC did a great job with this, as they do with all their products.
