Use this guide to remove and replace the glued-in battery from your 12-inch MacBook with Retina Display. This is best done with the help of an iFixit battery replacement kit; the liquid adhesive remover in your kit will dissolve the adhesive securing the battery, allowing you to remove it with ease.
iFixit adhesive remover is flammable. Perform this procedure in a well-ventilated area. Do not smoke or work near an open flame during this procedure.
For your safety, drain your MacBook Pro's battery before you begin this procedure. A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured.
The MacBook's battery contacts are located under the logic board, and this guide recommends removing the logic board completely for battery replacement. While it's possible to remove the logic board screws and simply tip the board up slightly to remove the battery, it's very difficult to install a new battery correctly with the logic board still in place.
Note: The solvent used to dissolve the battery adhesive can damage and/or discolor certain plastics. Take care where you apply the solvent.

Remove the following eight screws securing the lower case:
-
Two 1.8 mm P5 Pentalobe screws
-
Four 2.9 mm P5 Pentalobe screws
-
Two 6.1 mm P5 Pentalobe screws
IMPORTANT. You’re not removing the bottom, yet. This step is solely to separate the panel from its clips, permitting inside access.
The screws go in tangent to the curve of the case. If you aren’t used to handling small hardware try turning the screw counterclockwise while you feel for the hole until you feel it drop, that means the threads have aligned. It takes only light finger torque when they are threaded correctly

Use the flat end of a spudger to press and hold the small gold 'battery disconnect' button.
-
If the power LED is lit up, continue holding the button until the LED goes dark, and then release. This may take up to 10 seconds.
-
If the LED does not light, release the button after 5-10 seconds. Press and hold it again for 5-10 seconds, and release. Finally, press and hold it a third time for 5-10 seconds, and release.
cannot turn on the led after replacing the new screen, even after following the turn on instructions upper…
on reassembly, I had to plug my laptop in to reactivate the LED light
After reassembly I could not restart my MacBook using the power button or after SMC reset (shift-ctrl-option-pwr). I had to connect my MacBook to its charging cable to get the battery LED to re-illuminate. After that it was all normal.
mine doesnt turn on w anything, i forgot to click the buton to disconnect :_/
Same issue as above peeps. Followed ifixit directions verbatim and wasn't getting anything after screwing everything back in. Plugged in original 45W power block and waited, after few minutes battery LED came on and a min. or two after that, was able to get screen to turn on. Hope this helps somebody else.
May I ask how to get screen to turn on. I cannot get it work..
There needs to be mention of procedure for getting the repaired MacBook to power up again after the repair is completed.
I also am running into the issue described by others. MB will not come on again, even after being plugged into power and performing an SMC reset.
Kinda stuck….

Use tweezers to peel back the tape covering the trackpad cable ZIF connector.
-
-
-
Use a spudger to carefully flip up the retaining flap on the trackpad cable ZIF connector.
-
-
-
Carefully close the MacBook and flip it over once again, so that the Apple logo faces up.
-
Lifting from the front edge, raise the upper case/display assembly to about a 90° angle, and prop it up against something sturdy so you don't have to hold it.
-
Add a piece of tape near the track pad to secure the upper case and prevent accidental movement.

Remove the single 2.9 mm T5 Torx screw securing the battery connector to the logic board.
From my experience it’s important to carefully press and hold the small button above left of the Battery Discharge label. Use a plastic spudger or finger tip. The illuminated yellow LED to the right will go off. I believe this discharges remaining electricity from logic board protecting it during repair.
* I cannot find any documentation to support this, but I have damaged boards by not including this step.
What is with the all plastic end of this cable that appears to just be glued right on top of its connector?
Does the new one just stick back right on top?
(In this photo it is the bottom side of the cable below the white water indicator sticker)

As an added precaution, you may physically disconnect the battery by inserting a battery isolation pick between the logic board and the battery connector.
What happen if you don’t disconnect the battery? I didn’t and I saw smoke coming out when I connected the pad flex cable and the computer still started up
If you don’t disconnect the battery you might accidentally short something on the logic board since power is still running through everything while you’re working on it. You can complete the repair without disconnecting the battery, but you risk accidentally breaking your logic board. It’s much safer to keep the battery disconnected while you’re working.

Remove the two screws securing the USB-C port cable bracket:
-
1.1 mm Phillips #00 screw
-
3.5 mm T5 Torx screw
I’m at this point and the 1.1 mm Phillips #00 screw won’t budge and now I fear it could be stripped? Now what???
You could try to cover the tip of your screwdriver with a thin rubber glove to improve the grip on the screw while applying a little more downward force for the initial jolt. That might loosen the screw.
With my iFixit screwdriver kit, these were Philips #000, not #00.

Use the flat end of a spudger to disconnect the USB-C port cable bracket by prying it straight up from the logic board.
At re-assembling, when you reconnect this cable, pressing centre of metal plat is extremely important. You should feel tiny click when it connected properly. I encountered unrecognised external HDD and external monitor through USB-C even though charging in/out was OK, i.e failure of data transmission. I needed to re-open the back cover and pressed the metal plate again, then USB-C connection worked properly.

Disconnect the audio jack board ribbon cable by pulling it straight back out of the ZIF connector.
Make sure at reassembly that you insert the ribbon cable in to the jack board fully. It seems to take an extra push. The white line should disappear when it is seated properly. I didn’t get it in all the way by a fraction of a mm and had no sound (internal speakers weren’t even recognized). Went back and seated the cable fully and sound was back.

Use tweezers to peel back the tape covering the display cable connector.
I won’t have my daughter’s MacBook with its banana encrusted USB-C port until she returns home during spring break — just doing some homework before then. But if the case can lie flat after the audio board ZIF cable is detached, why do you need to detach the display cable connector (Steps 19-24)? It seems that you could jump straight to Step 25 to replace the USB-C port and avoid those steps.
Hi John, disconnecting the display cable is not necessary, but is recommended to avoid accidental damage to the cable during the rest of the procedure. If you feel confident in the safety of the cable then you can skip ahead. Good luck with the repair!

Carefully slide the flat end of a spudger underneath the display cable to separate the adhesive holding it to the lower case.

Disconnect the display cable by gently pulling it straight out of its connector.
I’m pretty sure I understand the instructions here, but I had to think about it a little longer because “… must remain closed when the cable is reinserted during reassembly …” was not clear to me right away. The retaining flap I discovered, is super delicate, and hence my paranoia, so I wanted to point this out in case anyone else felt like me: ''''Is it correct to assume that your instructions could be interpreted as:
“After disconnecting the cable, close the retaining flap for now to avoid damaging it. When reinstalling the cable, flip up the retaining flap once again, realign and slide the cable with gold contacts facing down.”
I bent the USB-C corner of the lower case from a short drop onto laminate flooring, so in I went to shape it so the edge wouldn’t snag or scratch things. I am typing on my MacBook that received the body work.
Thank you for your guidance!
For @seriouslyjohn and anyone else who might be wondering: “the flap must remain closed when the cable is reinserted” means keep it closed. Do not reopen the flap to insert the cable; just insert it carefully while leaving the flap closed. I know it probably runs counter to the procedure you’re used to, but Apple’s documentation is very clear on this, and I have to think it’s for a reason. My advice is to follow the instructions as written and don’t try to reinterpret them ;) Congrats on a successful repair!
Oops! I most definitely did NOT reinsert the cable into a closed connector. We can only wonder why Apple instructed this step to be counter-intuitive. I’ll pay closer attention to any weirdness that may arise, but the MacBook has been traveling and performing as it should; I’m going to avoid reopening the case, as easy as it is, until I have a good reason to do so. Thank you for replying and updating the guide!
I would argue that you should NOT close the retaining flap. I followed the directions to the letter, and when I started up the MacBook, the display did not register since the I wasn’t able to reseed the cable fully without worrying about tearing the cable. I did hear the computer charging and saw that the keyboard lit up, so I knew the MacBook was working besides the display. I looked up another video on Youtube that left the retaining flap open when reinstalling, so I took apart the Macbook again and tried it that way, and IT WORKED! The cable wasn’t fully reseated with the retainer open and I’m not sure if that was my fault or not, but with the retainer flap open, it was easier to see that. My 2 cents. Good luck everyone!

Use tweezers to peel up the tape covering the two ZIF connectors—one for the right speaker cable, and one for the audio jack board cable.

Use tweezers to disconnect the first antenna connector by lifting it straight up from its socket.
The supplied tweezer is no good. You need one with grooves as shown in the picture. When re-inserting the antenna connectors, make sure that they are seated properly before pushing down. If you have magnifying equipment, use that to get visual confirmation. I used tactile feedback from my fingers to discern proper alignment. Try not to force it.
I used the tweezers provided by iFixit. I struggled with both connectors and finally managed to disconnect both, but when I came back to reconnect them, I realized that both connectors on the logic board were loose. Long story short, it turns out that my little exciting adventure changing the battery cost me $530 to send it for repair at Apple Care. I am quite good at troubleshooting Mac and used to work for Apple for many years. This one step is more dangerous than it seems, because you can end up like me, without wifi on your mac. Honestly, for those who think they can do it, think twice. You can thank me later…

Once the logic board has been replaced, when following these instructions in the reverse order it should be pointed out that the all the flaps are flipped down. A distracted person might try to force in the flat connector before realising that he has to flip up the flap of the new logic board.

Remove the logic board.
If you are replacing the logic board once the machine has been rebuild the 2015 model has to have a 5W power adapter plugged into the machine first before the full 29W power supply otherwise there is a risk of damaging the logic board. Once the power is supplied the battery disconnect LED will switch on and once this has occurred you can remove the 5W and supply the machine with the full 29W power adapter.
While it’s true that the internal documentation specifies this for a 2015, after frying 2 motherboards with a normal charger, I spoke with the engineers and they told me that this also applies to 2016 and 2017 macbook main logic boards. I say- It can’t hurt to try to wake them up with a 5 watt charger first! Please take 5 minutes to save your motherboard.

Lift the back edge of the lower case assembly and prop it up at an angle using a book or foam block.

Apply a few drops of adhesive remover along the top edge of the front right battery cell.
-
Wait 2-3 minutes for the liquid adhesive remover to penetrate underneath the battery cell before you proceed to the next step.
Das ist nicht nötig. Ich habe mit einer schmalen Spachtel die Akkus sehr gut und vorsichtig vom Klebstoff getrennt.
Hat wunderbar geklappt.

Remove the battery by lifting it away from the speaker and logic board area.
-
Peel off larger pieces of adhesive using tweezers or gloved fingers.
-
Scrape away any remaining adhesive with a plastic tool, and clean the underlying areas with adhesive remover or isopropyl alcohol. Wipe in one direction, not back and forth, until all the adhesive residue is gone.
I used citrus oil. It’s vegan. Mr Jobs would approve ;) Made it very easy - less than an hour. After removing battery with the method shown in this iFixit, apply oil to remaining adhesive (black stuff included). Wait five minutes. Scrape black stuff away with plastic card etc. Wipe glue residue from edges towards middle (of each cell) with cloth. I used an old face washer. The nap picks up the clumps of dissolved glue residue nicely. Finish with clean cloth and alcohol. Looks like new!

Test your new battery's fit and alignment carefully before installing it.
-
Your replacement battery may come affixed to a thick plastic top liner to help keep the individual cells in position as you install it. Don't remove this liner until after the battery is installed.
-
If your battery came with adhesive pre-installed on the bottom, peel away the bottom plastic liner to expose the adhesive. If your battery did not come with adhesive, apply a thin double-sided adhesive tape such as Tesa 61395 to the lower case in the areas marked in red.
-
Carefully position the battery and set it into place. Press and hold each cell firmly for 5-10 seconds to secure it to the lower case. Afterward, peel off the plastic top liner along with any foam padding.

Calibrate your newly installed battery: charge it to 100%, and keep charging it for at least 2 more hours. Unplug and use it normally to drain the battery. When you see the low battery warning, save your work, and keep your laptop on until it goes to sleep due to low battery. Wait at least 5 hours, then charge your laptop uninterrupted to 100%.
hola a todos, yo le he cambiado la batería a todos mis Macbook pero el cambio de esta batería fue verdaderamente aterrador, les recomiendo que si está en su posibilidad económica pagar a un agente autorizado o una macstore hagalo, el cambio de mi batería lo realice yo y fue satisfactorio, pero me faltaron muchas herramientas. el Macbook no encendido a la primera destapar revisar volver a cerrar. la batería tiene una pega extremadamente dura y me costo mucho sacarla Suerte
hello to all, I have changed the battery to all my Macbook but the change of this battery was truly terrifying, I recommend that if it is in your financial possibility to pay an authorized agent or a macstore do it, the change of my battery makes it me and it was satisfactory, but I lacked many tools. the Macbook not turned on the first uncover review close again. the battery has an extremely hard tack and it cost me a lot to take it out, luck
To remove the battery, I applied acetone on the edges of the battery. Kept it tilted fir a few minutes and started prying with a credit card. Reapply acetone to the edge of the card, pry again, wait a few minutes and pry again. I thought it would be harder than it was. Removing the battery and all adhesive probably cost 30 minutes work.

When will the battery Start to swell?
Any warning sign for emergency replacement?
Is this Battery compatible with my Macbook 12-inch 2015 Retina?
Absolutely fantastic instructions. Just follow step by step. There will be no surprises. Took about 2-2,5 hours.
Guys! I did it! took me 2.5 hrs. really appreciate the thorough instructions!
Is this step necessary? I can’t perform this step as I am attempting to repair water damage and need to remove logic board & most likely replace the battery.
lamajr - 답글
@mac_medic You definitely don’t want the power coming on while the board is wet. In your case, I think powering on the machine to disable Auto Boot would do more damage than it prevents. I agree, skip this step and be prepared to disconnect the battery quickly if the laptop automatically powers on. Good luck!

Tried this on a 2018 MBP 13” Touchbar (there’s no iFixit guide for this model yet). Need to replace a broken screen.
Luckily I managed to connect to an external screen (Cmd-Down Brightness to switch displays) and enter above command. Seems to work, but there’s another problem with this model - it powers up as soon as any key is pressed……. ffs <gnashes teeth>

I unscrew the battery first and wrap electrical tape over the logic board battery connector before attempting any repairs to the board. Haven’t had any problems yet and I’ve worked on about 10 of these models already. Also when you open the bottom case use a suction cup at the bottom and pull up then run a plastic spudger along the edges to disconnect the clips. Also only use a plastic spudger on the board. Saw a youtube video from a repair shop and he did not disconnect the power and used all metal tools during the entire process of removing the board. His last step was to disconnect the battery terminal.

Hi. This does not work on 2018 13” MacBook Pro with Touch Bar. I did exactly this to disable auto boot. But when I check by using nvram -p it says: auto-boot true. Am I doing something incorrectly? I did everything step by step. Copied and pasted the sudo command, pressed enter and then entered my password. I have Big Sur 11.1 installed. Is there any other way since I need to replace the screen. Thank you. Adrian

Hi everyone. This is also a little pointless if you can’t see anything on the screen, and you don’t have a display adapter to USB C to display it. I agree with Brian about removing the back and disconnecting the battery cable before you even think about opening the lid of the MacBook. Applying the insulation tape is also a handy little tip that just makes sure there is no way to discharge from either the board or battery.

This step is completely unnecessary if you follow the guide to disconnect the battery properly. Just put some tape between the battery and logic board connection to prevent it from accidentally touching and therefore powering on the laptop.
