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.

Rating: 5/5 It's all about the screwdriver (and online video) December 5, 2016 Anyone can sell this battery, but the difference with MacSales is that the box included the screwdrivers and other tools I needed to properly install and calibrate it, The whole install took 10 minutes, but without the included screwdriver -- or video telling me where to find the deviously hidden screw -- it would have been impossible. I also really appreciated being able to get someone online after the order was placed who could confirm for me that the necessary tools were included. The products sold at MacSales are not necessarily "fool-proof," but my experience shows they come pretty darn close. Oh... and the battery worked great. Things are running like new.

Rating: 4/5 Just as good as the original December 3, 2016 The original battery in my MacBook Pro was nearing the end of it's life cycle. When it starting swelling up and affecting the trackpad (became difficult to click), it was time for a replacement. Having good experience with other OWC products, ordering a replacement battery from them seemed like a no-brainer. The installation was fairly straightforward. I followed the calibration instructions and then put the battery to the test. Battery life seems on par with the original battery when the computer was new. So far, I have no complaints. If your computer's battery is ready for replacement, this one is a good choice.

Rating: 3/5 mixed results unfortunately November 20, 2016 Battery performed well for a while but after about 150 cycles (which seemed like way too soon to start having issues ) battery stopped holding a charge for very long (would drain in an hour or less. And the mac data on how much charge not accurate - so machine would suddenly shut down even if said was 60% left...). I tried all possible troubleshooting options i could find (recalibrating battery, SMC & PRAM resets, etc).; nothing improved the battery's performance. Have struggled along (up to 240 cycles now) but has been very frustrating since cannot have laptop off charger for very long, etc. I have no choice but to order another battery and hope for better experience. I have always had great results with products I have ordered from OWC and with OCW customer service. Unfortunate to have my first less than satisfying with something I have gotten from OWC with this battery...

Rating: 5/5 Very good battery October 7, 2016 At first I placed wrong battery model number and had to ship back with my own shipping fee but OWC was nice to do full refund (typically they would charge 15% restocking fee). Then I ordered the second time with the right model but did not work due to defective one. Then contacted OWC and explained they sent me the replacement one within 2 days and I did not have to send back the bad one (save me shipping fee). This time the battery works like a charm. After calibrated battery by watching video on OWC website it seems the battery last very long up to 6 hours (or more). Thanks to all their team to make customer happy. I will recommend my friends.

Rating: 5/5 Great battery! September 24, 2016 It does what a battery should do and certainly delivers a nice long charge. Just make sure you look up how to properly calibrate it once you have installed in order to maximise its efficiency and get an accurate power meter.

Rating: 3/5 Battery drain just as fast as Mac batteries July 12, 2016 I thought I had just bought a new macbook pro. However, after a month goes by I started to notice the battery drained just as fast as the standard macbook pro battery but it wasn't as bad. The battery heats up pretty hot though. The only way to keep it going is to plug the power cable into the laptop at all times. I have a 2009 Macbook Pro, probably best to just upgrade the entire thing.

Rating: 4/5 Battery is Good April 3, 2016 I replaced the battery on a 2009 MBP. This is the 3rd battery that I have replaced and the first from OWC. It does not seem to have the same use life on a charge as an Apple Battery and does not discharge uniformly. Once it gets to 5% it sits there for a long time before it finally drains to zero. My best guess is that it lasts 1 to 1.5 hours less than the apple battery, but the upside is that it was cheaper. I would buy again at this point. It was very easy to DIY install with the tutorial videos.

Rating: 5/5 Quality, Tools and Reputation in One Box! March 14, 2016 I ordered a new battery from OWC after doing several hours of research regarding who offered the best service and product for a replacement battery for my mid-2009 MacBook Pro.

The battery arrived as promised and on time. The packaging was professional and secure. Inside the box was the battery with the tools necessary in order to facilitate easy removal and installation.

I've worked on computers for a good number of years and this was the first time i ordered a replacement part that included such clear instructions and was also packaged with much needed tools to facilitate the removal and installation process.

This company knows their product and I am extremely pleased! OWC is my first choice in replacement parts and upgrades for Mac!
