Rating: 5/5 Excellent battery life. Great Service from MacSales... March 17, 2017 I recently wrote a poor review for this battery because the battery indicator was going down to 10% after an hour and a half of use. MacSales tech support immediately contacted me to help me resolve the issue. Turns out even though the batter indicator on my MacbookPro was showing 10%, there' was plenty of juice left. I put the battery through a few cycles of deep discharge and charge (I did only one deep dicharge/charge when I first got the battery but apparently one is not enough). By the third cycle, the batter indicator caught up to the capacity and is now showing the correct percentage. The battery provides more than four hours of battery for my MacbookPro. Very happy with both the quality of the product and the helpfulness of support

Rating: 4/5 Outperforms the Apple battery for less March 15, 2017 Includes decent quality tools for the job as you may need a tri-lobe screw driver... Has better battery life than the original Apple battery. Unlike the Apple battery, this one needs to be "conditioned" before use so plan to install when you won't need the laptop for a day. Drop the old battery off at an Apple Store so that it is recycled and disposed of properly.

Rating: 5/5 No problems March 11, 2017 So far, so good. By all indications, this battery is just fine. Of course, the proof will lie in how it's doing a couple of years from now. One nice touch was that the two special screwdrivers were included in the package. The OWC installation video was excellent and helpful. I watched it before ordering the battery, to make sure there was nothing beyond my abilities. Now I need to follow their links to find where to recycle the old battery.

Rating: 5/5 Exactly what I hoped for. February 15, 2017 This battery is awesome. I bought it alongside a new SSD, and was slightly nervous as it was the first time I have opened up a Mac. However there was no need to worry- MacSales has tons of videos to ensure installation was a piece of cake, and a representative even contacted me to ensure that everything went smoothly. My battery life skyrocketed to around 3-4 hours from 1 hour at the max, before. Like brand new. If you're looking to replace your battery, you couldn't ask for much more when it comes to quality and customer service.

Rating: 5/5 Quality product refresh of Mac January 26, 2017 Replaced old battery that was beyond its "cycle" life. Determining correct replacement on website was simple and easy. After reviewing claims of performance, I expected some bump of performance in terms of battery life before requiring another charge but not seeing it. Maybe expecting too much. Install instructions were easy to read.

Rating: 5/5 Works great in my old MBP January 17, 2017 My second battery (for a different computer) that I bought from MacSales. Both NewerTech batteries have been working great so far. Easy to install. They included a tri-lobe screwdriver, and another screwdriver for taking out the tiny screws. Packaging was good quality. When it comes to batteries I'm glad to see they don't cheap out. I don't want my laptops catching fire.

Rating: 4/5 A little disappointing January 3, 2017 I received the battery promptly. A+ for speed of delivery. I was looking forward to installing this battery in my macbook pro. Installation was a breeze with the screwdrivers that were supplied with the battery. I followed the instructions of the online video for battery conditioning. I must say I am somewhat disappointed with the fact that it doesn't seem to hold its charge very long – a couple of hours when I use my computer as I normally do.

Rating: 5/5 Wow! November 23, 2016 Can't believe I didn't do this sooner.. Very easy to do the installation! I used coconutBattery to check the status of my old battery and compared it to this one after installation. Besides the higher mAh capacity, I feel like I can go for hours on end without having to plug in. Amazing considering my MacBook Pro is pushing 6yrs!

Rating: 5/5 Great Product! November 8, 2016 Only took 2 weeks to ship to Canada and out of the box came with 105.5% max capacity (diagnosed by CoconutBattery). So far so good, only time will tell it's actual lifespan. Definitely a cheaper alternative if you don't want to invest in brand new macbook.

Rating: 5/5 Came in under 5 business days and fit perfectly September 25, 2016 UPS Sure Post can take a while getting to me but this was delivered to my local post office and came next day. It went in very easily. The construction is better than the original. After the initial calibration and full charge, I let the Late 2011 Macbook pro play Youtube videos for seven hours before shutdown. How well it lasts is to be seen but I suspect it will last longer than the Macbook will be supported. The supplied trilobe and precision phillips screwdrivers were perfectly adequate for this onetime use. Being magnetized was a definite plus.

Rating: 5/5 You get what you expect April 19, 2016 What is there to say except that the batteries arrived earlier than expected and the package was complete with two screwdrivers and the videos are available online to support the replacement. The added advantage was that there was at least 60% charge in the battery when it arrived.

Rating: 5/5 Only this replacement battery worked! April 3, 2016 I ordered a replacement battery from amazon, guaranteed to work, but it did not, something drove the processor into overdrive, using 100% at all times, scared the heck out of me, super slow to start up and react, fan's blasting, mouse erratic. Returned this battery, ordered a second one from another suppler who guaranteed it to work. Same deal, slow start up, cpu going crazy. Returned this one too. Spoke to a local Mac expert and he recommended this specific battery as a replacement, he had used it many times with optimal results. 2 day delivery to the door. Awesome

Rating: 5/5 Comes with Everything You Need February 8, 2016 I ordered this battery while I was traveling, due to the dismal performance of my existing battery. The battery arrived with all the tools I needed to perform the replacement, including both the removal of the cover of my Macbook, as well as the battery.

The instructions provided were simple but also sufficient to ensure that I could easily complete the process without damaging the internal components.

Within minutes I had completed the battery change, and was up and running again!

Rating: 5/5 A perfect replacement for my laptop January 7, 2016 I own a 2011 MacBook Pro which typically is closed as I use an external monitor, mouse and keyboard. This resulted in the battery eventually overheating and expanding causing the trackpad to no longer recognize mouse clicks. The replacement battery installed with no problems (thanks to the included Tri-Lobe screwdriver) and is working as expected. I recommend this battery for anyone with issues similiar to mine. The price is reasonable, the instructions are descriptive. I did check out a few online videos to know what to expect once I removed the back case. One of the screws holding in the factory installed battery is hidden by a label (do not remove this battery) which the instructions did not indicate. I would order again.
