Fancy Buying A1417 Laptop Battery Replacement for MacBook Pro 15 inch Retina A1398 [ Mid 2012 Early 2013], fits MD831LL/A MC975LL/A MC976LL/A ME665LL/A ME664LL/A

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.

Woke up and MacBook was dead. After some research it appeared that the battery was no longer working. I needed a replacement quickly! So Amazon it was. I was a little skeptical of the battery replacements available but I chose one with a lot of good reviews. Ordered it and it came the next day. Took about 2 hours to install. It went pretty smoothly. After resetting the pram it showed that the new battery was working normal. At the moment it actually lasts quite a while compared to the old Apple battery and it also charges fine. So far I am very happy with this battery especially for the price. Apple wanted a lot more money and it would take a while to get back.

Works exactly as described. Be sure to check out some videos that show you how to properly charge these up to start. That will lengthen the life of your battery! People still leave these charging overnight or even longer allowing the cells inside to burn out prematurely and then wonder why their batteries don't seem to last very long. A little common sense goes a long way when it comes to battery maintenance. I currently have a 13 yr old laptop which is still using it's own OEM battery. Yes, the same on that came with it! Luck? No, properly using it as it should be. Never charge to 100% unless absolutely necessary. 80-85% charge limit will make your battery last for MANY YEARS! In special cases (limited), if you don't have access to a charger you can charge to 100% but don't do it regularly, it will kill the battery lifespan! These work and I expect it to get a good 5-10 years of use easily.

Well, I'm not sure how to rate this battery. I installed it into my wifes Gateway NV57H13u laptop and it fit perfectly. Powered it up... nothing. I plugged the charger into laptop and it booted right up. Quickly checked the battery level and it indicated 1%. So clearly the battery was delivered dead. I charged it up to 100% and used the laptop for 3 hours before charging it again at 8%. It charged up fine. That was only part of my concern, I'm wondering how the service life will be affected. These batteries do not like going flat for any period of time. As I said, form, fit, function was excellent after charging. Delivery was to wrong address--but that is on Amazon, not the seller. Update: Charged battery to 100%, used for 2 1/2 hrs (30%). Laptop shut off and on plugging in and restart battery showed 1%. This battery is bad.

The battery works and the kit came with all the things needed to do the job. It is, however, one of the worst batteries ever to install. The battery does not seem to last as long as the original did new but it does the job and runs all the features. I have had some batteries that fail fail when the GPU kicks in, this one seems to do the job.

I bought this battery for an old Gateway NV57H laptop. Came in a sealed box and the battery was in a sealed anti-static bag. Was easy to install since there is just a sliding lock mechanism to remove the old battery. It fits like a glove. Battery had about 40 percent charge and I charged it to 100 percent after installing per document that came with the battery. Disconnected the laptop power adapter and the laptop ran on battery for several hours before going down to 20 percent charge, so now charging it back up. Not sure how long it will last but so far all is good.

Works as it should. Good product!

Battery came almost fully charged, used it in the laptop for the last 3 days and it's still holding more than 50% of its power.
