I have a MacBook Pro Early 2013 Retina which for a while has been giving me battery issues, and won't hold charge long if unplugged, so decided to gamble and buy a new battery for it. This is not OEM, but gets the job done.For me the work I got it to fit was to lined it up correctly where I needed, test it out a few times and then I took out the adhesive from the back and laid it against the Mac softly so I could adjust it left or right as needed to fit the screws toby the connector (the piece that connects the battery to the motherboard). then I added simple pressure to the rest of the pack. Noticed on the pictures that the battery does not cover all the space at the bottom, there is a gap compared to the original battery, however everything else matches up.I did have a bit of trouble getting the connector in, notice your original battery how the connector wires are actually bent to let it fit down, where this , since is new, the connector wires all came straight so at first seems like its he wrong connector or won't fit, but what you have to do is easily bent them down allow it to the connector to fit/click in place ( just take note of how your old battery's connector wire is bent and try to form the shame shame). I used the small plastic stick that came with the package , to help add pressure down to hold the connector wires down while I bent it down with my fingers. Once you get that done and plug it in, no issues.Took about 1hr to full charge. (when I first plugged in it was charged showing at 66%). The instructions recommends you let it drain away to 2% (no 0%) and then do a full charge.Also the battery (as I mentioned above) comes with an adhesive which you remove and makes it stick to the motherboard (above the trackpad), however on top of it there is also a small plastic clear thin film, which you also remove after you are all done, before closing the case.see the pictures of the installed new battery vs my old all swollen battery. On a scale from 1-10 to replace this battery, (1 very easy , 10 very hard), I rate it about a "4" , however removing the old battery itself I rate it a "6". Do be careful when you remove the 2 middle batteries , do it slowly and carefully otherwise you will rip off the metal plate that sits between the trackpad and the battery. I mostly followed the advise of videos I found on line to use a string and put it under and slowly pull/saw left to right to help remove the old battery.

CHECK UNDER THE FOAM! When installing it would have been so much easier if I had the spatula tool under the foam. I can see people not checking and just throwing it away. And of course I didn’t see it until I was done. But my track pad is working again and no problems so far.

Just know you're getting into some work removing the old battery. There are some good videos on YouTube to help, don't follow iFitIt's 74 step process.With that said, the battery seems to fit. I'm working with the seller to see what can be done since the wires are too long to make the connector line up with the pins on the motherboard.

I'm an experienced Mac technician, so battery replacements are pretty easy. Installation was easy with this battery, although the adhesive isn't the best. I fully calibrated the battery per the instructions, but I am VERY frustrated with this "brand new" battery. My MacBook Pro will shutdown at about 50% battery. A battery information app I use shows that this battery is way under capacity (at about 85%). My Mac runs slow when on battery power and dies randomly. Clearly this is a battery issue. Save your money and purchase from a more reputable brand.

Works well. Great price. Does not last nearly as long as OEM battery but for the price it is a great value.

Good battery, easy to swap. We'll see how longevity is with it.

The sticky backing on these batteries is weak. I very carefully cleaned the inside of the case with alcohol and dried it thoroughly, but one of the battery segments keeps coming unstuck. I'm going to try again to secure it with some two-sided tape. Still giving three stars since the battery holds a charge and works fine so far.
