Upgrade Your Apple MacBook Pro Retina 13" With NinjaBatt A1502 A1582 Battery - Long Lasting [71.8Wh/11.43V] Review

My battery came with no instructions--not even a link to additional information. Fortunately, a family member directed me to Ifixtit.com, which has excellent, highly detailed instructions. In fact, I bought another battery from Ifixit and installed it after removing the battery from Revain. I just felt more comfortable about the safety aspect, since a lithium ion battery can be extremely dangerous--not just during installation, but long term. I should note It's not an easy install--it took a…

Installed this in my 2013 MacPro and it worked perfectly. Instructions were easy to follow and I can keep using my MacBook for a few more years!

This battery was purchased in March, 2022, and installed in a MacBook Pro model A1502. It worked perfectly until very recently, August 7, 2022 when it caught on fire charring the inside and melting keys on the keyboard and melting a portion of the screen. At the time of the fire, the computer was sitting on the kitchen counter, closed and not plugged in. Smoke started coming up from the unit and it got very hot to the point where it could only be picked up by using hot pads.

I replaced the battery on my MacBook although after opening it, I found out only professionals are supposed to do it. I looked online on how to replace the battery and I’ve been using for almost a year now with no complaints

So far so good. My laptop didn’t die for 3 days now! My old battery needed to be charged daily. We will see how it does in a year or two

Replaced battery in MBA, worked well first 6 mos. Off charger life degraded quickly to less than an hour, eventually after 12mos to less than 10 minutes.Replaced battery in MBPr - Essentially the same results. Unfortunately I replaced the MBPr battery about 3 mos after the successful effort on the MBA. Gave these folks the opportunity to support the product before I wrote this review, that was 3 weeks ago now, with no reply. So, I say Don't Buy! It's a fair amount of delicate work to replace…

This is my first ever MacBook battery install, and it went without a hitch. I took a gamble because there were no previous reviews on this particular product. For the price it fit perfect and has decent battery life so far in my 2015 MacBook pro. The included screwdrivers were a nice bonus. Getting the old battery out was much harder than putting this new one in. I used 91% isopropyl alcohol to loosen the adhesive and an old debit card to get underneath. Only time will tell if it last. I'll…

I am using the battery only for two weeks but it works well so far. I did stress testing with Prime95 and the whole system (MBP 13" 2015, A1502) worked well. The installation was not difficult (if you did similar type of work with electronics before).

Replace my old battery as it was swollen and would not hold a charge. After putting all pieces back together, the Ninja battery worked fine, but the keyboard and track pad were inoperative. Disappointing. Reading the web, decided to replace the trackpad ribbon cable which runs over the battery (bad design). Then replaced the track pad ribbon cable, but no joy. The keyboard and track pad were still inoperative. Very disappointing. Then read web again and found that trackpad might need to be…

Followed the instructions to a tee to remove and install, removing adhesive was the hardest part but possible with the right tool and solvent 99% alcholol.Has worked without major problems and seems to hold charge well.

I loved that the "NinjaBatt” was so easy to install that a "Caveman” could do it! As soon as I tightened all the screws to the laptop. The problem that I had my MacBook Pro "Booting up and shutting down” was over! The laptop booted up just like new!
