Rating: 5/5 Quick delivery, easy to install and provides good working time. April 25, 2018 Order was processed and shipped the same day. Battery came as promised 4 days later. The battery came with small screwdrivers that made removing the old battery from my 2009 MacBook Pro and installation of the new battery quite easy - 10-15 minutes tops. However, I had to use my No 0 Philips head screwdriver, as the one provided didn't fit. Steps to condition the battery were well-described and easy to follow. Able to work 4 hours and only discharge the battery to about 40% charge. Vast improvement.

Rating: 4/5 So far so good.... March 25, 2018 My 2009 15" Macbook Pro's original battery was no longer holding a charge. This battery so far, seems to be doing well. I get about 4 hours of charge out of it, after I had performed the installation and calibration. The only complaint I do have is that this battery is heavier than the original that came with the computer, so that makes the laptop much heavier now.

Rating: 5/5 Battery Lasts About 4 Hours and Came Quickly March 12, 2018 The battery arrived in about 5 days and just from the looks of the box and the packaging you could tell it was much higher quality then the batteries from Amazon. I tried 2 batteries off amazon that were around half the price and they were horrible compared to this one. Not only did this battery get about 3x the battery life, it fit like a charm and was extremely easy to install. So far after calibrating the battery it has lasted around 4 hours. Very happy with this purchase.

Rating: 4/5 This Product Worked flawlessly December 3, 2017 My previous battery was completely dead. I was told (by a Geek at a local store) that my Mac needed to be recycled. Glad I found MacSale.com because my Mac is working perfectly now. The step by step videos on how to install were great. After following the video instructions the battery lasts for hours once Mac is unplugged.

Thanks MacSales.

Reviewer: sliverga Location: East Coast, USA Age: 35-44 Experience Level: Power User Owned Product: over 6 months
Rating: 5/5 Excellent battery. Swelling only began after 2 years but this is not Newer Tech's fault that it causes trackpad problems. August 21, 2017 The battery only started swelling up after 2 years, which causes the battery to physically contact the trackpad and prevents the mechanical trackpad pushbuttons from properly actuating in the 2009/2010 era MacBook Pro models. The lack of room between the battery and the trackpad to accommodate swelling is not Newer Tech's fault, but Apple's. I would much prefer to have a 0.1" thicker laptop, or even thicker, preferably with a removable battery, like all the previous PowerBook models I owned. Bring back the removable battery, Apple!

I purchased the battery in October, 2015 and it only started swelling up in August, 2017. It has 11 cycles on it according to the Coconut Battery program. It currently states design capacity is 7200mAh, is currently at 7273 mAh and full charge capacity is 7273 mAh.

Great battery. Highly recommended. I will continue to purchase these as frequently as necessary to keep this 2010 15" MacBook Pro running as long as possible. I would bet that anyone else who ordered their MacBook with the matte screen is also doing the same thing.

Keep up the great work, NewerTech!

Rating: 5/5 Better than OEM Battery, great overall package! April 27, 2017 Used this battery for a client whose Macbook was down to 67% of original battery capacity. I had read good reviews of the batteries from MacSales.com before purchasing and was not disappointed. The battery fit perfectly, came with all the specialized tools necessary to complete the swap, was packaged securely, and best of all has 113% of the OEM battery's original capacity! I would highly recommend any of the NewerTech NuPower batteries if you have a Macbook with shrinking battery life.

Rating: 5/5 Works as Expected April 4, 2017 AS others have said the battery works as expected and now I can use my MacBook Pro without having to constantly charg the battery. Nice that the battery kit contains all of the needed screwdrivers and it only takes minutes to swap out the batter. I replaced the batter almost a month ago and I have not encountered any issues. I am happy with my purchase.

Rating: 3/5 Battery doesn't last as long as other reviews March 30, 2017 I'm barely getting four hours per charge. I followed the instructions regarding fully charging then draining the battery, helping break it in, but I still get disappointing battery life. Installation was easy and I really appreciated having the tools included. I'm not sure if I'm disappointed, I just know I'm not very satisfied. I could've paid the apple store 50 dollars more for a lot more assurance.

Rating: 5/5 Like a glove. Easy install. Better battery life March 23, 2017 What is there to say that has not been said by others? This was a very straightforward removal and installation. Battery holds a charge for twice as long as the old one did. I am getting 4-5 hours of use compare to the 2.5 I was getting. Highly recommend to other folks with older macs that want to keep using it for a few more years.

Rating: 5/5 Made my laptop a laptop again March 13, 2017 I needed a new battery because my original one was struggling to give more than an hour's worth of power.

At the recommendation of a friend, I ordered from MacSales.com. I found what I needed easily, ordered it, and it came very quickly.(Thanks for the tracking number.)

After arrival, the installation instructions were easy to follow, and I got the old battery out and the new one installed in less than 5 minutes. I followed the battery calibration instructions on the website and have been very pleased with the results. I don't have long-term use stats at this point, as it's only been about three weeks, but so far, so good.
