Great tutorial. I've followed advice from the comments which warns about isopropyl alcohol leaking to the screen, so I packed it with plastic film. In the end of process, there was isopropyl alcohol leaking from the keyboard, so protecting the screen is mandatory. I ended up replacing the speakers from another tutorial, now my rMBP feels brand new. Thank you!

Definitely worth mentioning to put a sheet of foil between the keyboard and the screen to stop excess IPA from leaking through and damaging the screens anti reflective coating.

Excellent video. I’ve just done mine this evening and it took me approximately an hour. You should add that the new battery needs to be calibrated after it’s been installed though. Also, once the case is open, you should take the opportunity to blow out the dust from the fans and grills. You’d be surprised at how much fluff accumulates in a 2012 laptop.

Thanks for this very clear video, I'm in the process of cleaning the old glue. Two observations: 1) I and my wife between us have taken more than 2 hours to clear the glue from the outer two bays, we still have to tackle the loose central plate !! 2) I now understand why the Apple charge is so high, imagine a qualified technician spending 2 hours + to clear off glue. It is about time that Apple reverted to using screws and straps instead of glue/sticky tape. There is no reason why this battery needs to be glued in place. THe chassis could have ridges to give full lateral location and the vertical security could be by a moulded plastic cover secured by the existing battery screws and the 2 speaker housing screws. This use of glue is why I moved away from an iMac (when my 2008/ failed) to a Hackintosh on a fully customisable PC as all post 2013 iMacs are assembled with double-sided tape for which Apple ask £25.00 for a replacement pack and official repairers have told me that only the Apple tape works !!

I'm so thankful for this video and the helpful comments. I'll be repairing mine soon instead of spending so much more at a repair store.

Worked for me- I had massively swollen batteries. I think make sure you tilt the mac so that excess IPA goes towards the battery side and away from the boards. Just go slow and you'll be fine! Bonus: this fixed my touch pad too (couldn't click due to the older swollen batteries...)

Great video 👍

You are a star! Just purchased a battery, opened the case and looked at the 50 steps iFixIt would have me do to completely remove the motherboard and all modules... but one look and I thought all that seemed unnecessary. One google search later and you've confirmed my thoughts. Cheers!

Thank you, just used your method instead of the full disassembly proposed by other people.

Great video. All advice should be followed. I use isopropyl (rubbing) alcohol (about 1 ounce) to soften the adhesive. I drizzled it over the top of the battery and then used an old, flimsy credit card to push the alcohol into the gaps. My new battery was slightly shorter (front to back) so I was able to line up the two screw holes first and then let the battery flop into place. Once the bottom plate was on I flipped the laptop over and wiped away any alcohol that had seeped through the trackpad. Overall took about an hour including cleanup. Charged overnight and now working perfectly.

Great video doing mine tomorrow Thanks buddy

Thank you!

HELP this won't make the trackpad stop working right? I'm attempting this in a mid 2012 MacBook pro 15 inch a1398....

PC all the way. This is nuts.

Where does that brown card (?) peice over the trackpad back (at 6:17) came from?

Why at minnute 6:17 a black pad appears in the center of the battery space?

Can I use rubbing alcohol instead of the IPA?

How can I get my computer to read the battery percentage? I cannot figure out how to change it in settings. I have no idea if the battery is charged or not.

Nice! How many hours does it run for before needing a charge?

Why does ifixit have you remove so many components not even near the battery??

Minute 5:52 - cleaning the residue. Make sure you emphasize to put the pressure plate back over the trackpad. I missed that step and had to redo it. You show it there at minute 6:20 but you never say to make sure it's there. I missed that once I shut down the laptop to do the process. Oops ! LOL. Easy fix.

Hi, was it an original apple battery or a replacement one? If it was an original one, where did u get one?

what do you mean by game over when referring to damaging the battery. Will that fry the motherboard or something else?

Move your camera to the front i can only see your hands.

1:06 right where you are pointing at, 1cm higher, there is a connector with a 6-wire cable running across the left screw (1). It doesn't seem to exist in your case... 🧐 Remove before unscrewing. It is tricky because the plug is encased in a thin plastic wall. A spudger is too wide to get under the cables, so, gently pulling it in all directions helps and it popps off.

I would have left the plastic on the back side, at least on most of that glue. There is no reason for that much glue, it's just Apple being Apple. I wonder if they make a larger battery for those models. I got a 33% larger battery for my iPhone 6S and there should be one made for this. I just watched another video that removed EVERYTHING before they got to the battery removal... Glad I watched this one :D

Hi At 6:18, there is a new cover over the touch pad. Is that from the old battery?

What is this coverage of your MacBook on its top?? :D

CAUTION: EVMYT indicates his screwdriver is TOREX (6 Teeth). It is a PENTALOBE (5 teeth). They look the same and fine if one comes with your battery but don't use your TOREX bits for this.

what scew driver did you use

I did step by step u.u and didn't work 😭

They won’t even replace the battery on mine they said it’s too old. 😜

Worth pointing out that you have to use the alcohol very, very sparingly and work very, very slowly. I didn't and the excess alcohol seeped under the keyboard and has damaged the logic board. One dead lap top with a new battery!

Is apple battery the best?Or is aftermarket ok ?

Don't you feel even the slightest bit guilty at depriving poor apple of £130 in revenue? Think of all the poor workers at Genius bars who will be made redundant! .... JUST KiDDING 😄. Thank you for going to the effort of making this video and sharing with the KZfaq community. I will be using it to replace the battery in my unit. One small bit of constructive criticism - I would suggest temporarily connecting and testing the new battery BEFORE removing its protective plastic from the adhesive pads. That way you do not have to go through the hassle of remvoing it if it does not work and furthermore you can return it in good condition. PS - If I didn't know any better I would swear that Apple deliberately made replacing the battery as user unfriendly as possible in order to maximise profits from repairs and to encourage purchase of later Macbook Pro models.

That IPA stuff doesn’t mess the board up?

Broke my MacBook yesterday. Alcohol went through the keyboard and damaged my screen. Fuck my life 😫

Handy video but that music was very distracting :(

Your hand is always in the way of the camera.

The music is very annoying.

Jesus dude, your ridiculous music is so loud, I can't even hear what you're saying.

why have you got that f****** music blasting
