Use this guide to safely remove the glued-in battery from your MacBook Pro with the help of an iFixit kit with adhesive remover. The adhesive remover 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.

To minimize risk of damage, turn on your MacBook and allow the battery to fully discharge before starting this procedure. A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured. If your battery is swollen, take extra precautions.

Note: The solvent used to dissolve the battery adhesive can damage certain plastics. Follow all instructions and take care where you apply the adhesive remover.

  1. Before starting this procedure, you must disable your Mac's Auto Boot feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. Use this guide or follow the abbreviated instructions below to disable Auto Boot. This command may not work on all Macs. Power on your Mac and launch Terminal. Copy and paste the following command (or type it exactly) into Terminal:

    • Power on your Mac and launch Terminal.

    • Copy and paste the following command (or type it exactly) into Terminal:

    • sudo nvram AutoBoot=%00

    • Press [return]. If prompted, enter your administrator password and press [return] again. Note: Your return key may also be labeled ⏎ or "enter."

    • You can now safely power down your Mac and open the bottom case, without it accidentally powering on.

    • When your repair is complete and your Mac is successfully reassembled, re-enable Auto Boot with the following command:

    • sudo nvram AutoBoot=%03

    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 - Antwort

    @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>

    Cool_Breeze - Antwort

    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

    Adrian Vizik - Antwort

    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.

    Roberto Enrieu - Antwort

    running `nvram -p | grep 'AutoBoot'` in terminal verifies that it was accepted

    result: `AutoBoot %00`

    Marek Polák - Antwort

    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.

    Grant Ormsby - Antwort

    It took me a few tries to make this command work, as I was able to copy and paste the command into Terminal, but could not type in my laptop’s password. I finally typed my password into a text document, copied it (command C), and then pasted it into Terminal and it worked.

    • Before proceeding, unplug and power down your MacBook. Close the display and lay it on a soft surface, top-side down.

    • Use a P5 Pentalobe driver to remove the six screws securing the lower case:

    • Two 6.2 mm screws

    • Two 5.3 mm screws

    • Two 3.4 mm screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

    Before any repair is carried out that involves removing the bottom case, the machines auto-boot function has be disabled. This can be disabled via the terminal command “sudo nvram AutoBoot=%00” once the repair has been completed the auto-boot function can be re-enabled via the vermin command “sudo nvram AutoBoot=%03”.

    Aaron Dalziel - Antwort

    I recommend that you have an organizer tray for all the small parts, and label it in advance with the numbered “step” associated with each removal of screws and other parts. It really helped me when I needed to put everything back in reverse order, after the new battery is glued in place.

    I initially tried shifting the whole panel off the front after using the separating tool to make some space at the back where the hinges are. I only had luck when I pushed the panel back to it’s normal state and using the separating tool again to open the front, then getting my fingers underneath the slide it off the front was easy. I guess the lesson is to not use the separating tool to “push from the back“.

    The tape will likely not adhere as well as when it came out of the factory. This isnt an issue! As long as the tape is in place when the lower cover is put back on the device you should be good to go.

    The underside of the tape is not uniform. Therefore, pay attention to which direction it is placed by looking at the underside when you remove it. Possibly mark one edge so that you can replace in the same direction during reassembly.

    the cable connector (where the twizzer tip is) should be cleaned with alcohol or acetone before insertion because the cover (where the tip is holding it back) will have glue deposit smeared on top of the connector circuit traces. Glue will prevent a good connection with the BMS.

    tarex7 - Antwort

    The little tab that you pull back on, at least in my cable, was simple glued onto the rest of the cable. I tried to carefully remove the cable, and the tab came off. I did not have flat tweezers in the ifixit replacement kit and did not want to pinch the cable with sharp instruments. Therefore, be extremely careful when removing the tab as it is difficult to reattach the cable without it.

    Rick Jaffe - Antwort

    Same problem with the tape coming loose and the cable not coming out. Go further back along the cable and pull gently on the cable with your fingers and the connector will come out easily.

  12. Fold the battery board data cable back and out of the way.
    • Fold the battery board data cable back and out of the way.

    • If you're replacing your battery, you may need to completely remove and transfer this cable to your new battery. Disconnect both ends and carefully remove the cable. During installation, be careful not to install it upside-down or backwards—note the orientation in the photos.

    The new battery I received did not come with the battery board data cable, so I had to remove the existing one and transfer it. The lock at the smaller end is the same mechanism as the one at the end shown in steps 11 and 12, but smaller (and harder to see. It helps to gently straighten the left end of the cable before trying to insert it in the end of the replacement circuit board.

    MikeG1 - Antwort

    I can corroborate MikeG1’s comment. My battery came without the long data cable as well. I had to remove it from the fried battery. Plastic lock tab mechanism on the ZIF connector is smaller. My inspection microscope helped to transfer the cable to the new battery board. Thanks Mike!

    lamajr - Antwort

    Likewise - the new battery came without a data cable. The cable was successfully removed from the old battery assembly and installed on the new battery, but it was tricky and nerve-racking (the cable is delicate and the connectors are very small) without instruction provided! The instructions should be updated to highlight the missing cable possibility, and provide information/illustration on transferring the cable.

    Marc - Antwort

    In step 13, notice the amount of the data cable that sticks out of the connector. When moving this cable to the new battery, it is difficult to tell how far to push the cable into the connector or when it is fully inserted because the cable is so bendable.

    Rick Jaffe - Antwort

    AMEN!! This was the hardest part of the ENTIRE process! Hard to know when the small end of the cable was “fully” inserted. Cable is SOOOOO delicate!

    • Use a T5 Torx driver to remove the 3.7 mm pancake screw securing the battery power connector.

    When the battery management “BMS” circuit board is re-installed, loosely install the two 3.7 mm screws, put a spudger on the left side of the BMS board to wedge theBMS board to the right then tighten the two 3.7 mm screws. The reason for doing this is that the two power traces on the board may not make physical contact with the battery connector (connector at where the spudger is on step 15). One clue that you didn’t have physical contact is if you reinstalled everything but there is no power unless the AC supply is plugged in (with battery meter on the top at 0%). This was what happened to me. The reason is that when you bend the battery connector in step 15, it’s no longer in alignment with the traces on the BMS board and hence, you have to shift the BMS board to the right to compensate. Once I did this, voila 64% power.

    At this point I Jump to step 30 . I do not use the liquid adhesive remover method. I use a silicone rubber kitchen food scooper. The scoop end is a soft, silicone rubber material with a beveled edge. The handle is a hard plastic. This tool I’ve used in about 50 retina battery swaps. No floss, credit cards or metal spatulas for me.. The angle of the ends and the rubber pliability combined with the hard plastic handle is ideal. After a few repairs you will get better at it. Be careful when applying pressure or leveraging to get between battery and base. You don’t want to slip & “overshoot” the scoop end into the logic board. EASY DOES IT…Save yourself the mess of applying the liquid. I can remove a battery in 10 minutes. Here’s the link to this tool that I found in my GF’s kitchen:

    I started from the top. To do so, I had to lift the battery control card (step 24) enough to be able to put the power connector (step 15) back below it. That way I could slide the card all the way.

    Because of the way the tutorial describe it, I was conservative on the quantity of remover. That may be why this step was not easy.

    • Lift and remove the battery.

    • Before installing your new battery, remove all the old adhesive from the MacBook Pro's case.

    • With a little luck, you can slowly pull out each strip of adhesive with your fingers.

    • Otherwise, soak each strip of adhesive with a bit of adhesive remover for 2-3 minutes, and then scrape it out with a plastic tool. This can take quite a bit of work, so be patient.

    • Mop up any remaining adhesive remover and give your MacBook Pro a few minutes to air dry.

    • The replacement battery included in your iFixit kit comes with adhesive pre-installed. Test the battery's fit and alignment carefully before peeling off the film covering the adhesive, and then press each cell firmly into place. If any additional films/liners are present that weren't on your original battery, remove them now.

    • 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%.

    • If you notice any unusual behavior or problems after installing your new battery, you may need to reset your MacBook Pro's SMC.

    Hi Jeff,

    Thank you for the great instructions! With a piece of dental floss it goes even better. Also it’s good to explain to shift the back cover out after removing the bolts. At the moment to put in the new batteries it’s the best to tighten the batteryprint first and at last to fix the batteries. Put three pieces of plastic under the batteries to prevent fixing too early to the bottom.

    Frans.

    Thanks for your comment! It was really essential since dropping the battery in the case without its control card being attached could have resulted in the impossibility to connect it.

    I had a non-ifixit battery replacement fail due to battery wiring (flat coated copper) touching the sharp edge of the case aluminum. Eventually vibration caused the insulation to wear off and short the middle cell to the case. Failure after a couple weeks.

    J’ai remplacé la batterie de mon MacBook Pro en suivant à la lettre ce Tuto.

    Un grand merci.

    Stephane RUE - Antwort

    Overall good guide. The battery removal was by far the most difficult and time consuming.

    It's important to understand stand that the battery is separate from the mother board so you can get somewhat aggressive when removing the old battery without worrying about damaging it.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted back to 100%.

Take your e-waste to an R2 or e-Stewards certified recycler.

Does the replacement battery comes with the same strong adhesive as the original battery?

Surgie - Antwort

I ordered my battery for the 2017 version of the Macbook Pro with function keys from ebay and it didn’t came with a adhesive strip. I am sure you can use your own adhesive strips or double sided tape, as long as you mind the gabs on the aluminum frame,

Serj Nko -

Thanks for the great guide! Can you copy the guide to the Macbook Pro 2017 thread, as it’s exactly the same procedure for the function key version? It might be obvious for some “Pros” but I realized it after some trial and error odyssey.

Serj Nko - Antwort

Hi Jeff,

Thank you for this great work to beat Apple greediness. I followed the exact steps and everything went well, but my battery is not charging nor the status is shown on the bar! I tried restarting and resetting and even restoring and it did not work would that be something you can help me with?

Bashar Khiatah - Antwort

If the old battery still works, try putting it back in, and see if that clears up the problem. If it does, the new battery is defective.

i did this one today with just 1 bankcard in 30min time no adhesive loosener needed no head needed…. you don’t even have to remove the mousepad…

i might have to start making my own repair guide….

demeyermike - Antwort

Glad yours was easy! The strength of the adhesive can vary a lot depending on age, heat cycles, how much was applied at the factory, etc. I’ve seen a few that were easy and quite a few that were absolute monsters to remove. Most fall somewhere in between. This guide should have you covered in all cases, but it probably doesn’t hurt to poke and pry a little before you start, in case you lucked out and got an easy one. Just be very careful not to puncture the battery. Thanks for your comment!

Jeff Suovanen -

I can confirm that this guide also works word for word for a 2017 MacBook Pro with function keys. All I would add is that Step 7 requires considerable force!

Jon Worth - Antwort

I did not remove the trackpad or use adhesive remover (Macbook Pro late 2017). Just need to get underneath the battery cells and push through the factory adhesive/tape. The entire process took around 30 min doing it this way; I’m handy, though no pro.

renob - Antwort

Thank you! This excellent guide gave me a lot of confidence in the replacement of the battery. All went precisely according to plan.

Giovanni Gervasio - Antwort

Excellent instructions. I did it slowly as it’s my first time with a Macbook Pro. Took me 90 minutes. I added some comments in steps 13-15 because the battery wasn’t connected properly on the first time.

tarex7 - Antwort

I just completed the swap… awesome guide and really easy.

The only Problem i had was the missing data cable from the battery board to the logic board which was not included with the new battery. Thanks to some comments from other users I used the cable from the old battery.

Everything Else worked as described.

Mirko Bjelic - Antwort

Great guide, thank you. I am replacing my battery and have a question about Step 13. Would it be possible to show how to disconnect this end of the cable (the hook end). I am having a hard time getting it out.

Thank you in advance for any help/advice.

Worked just perfectly, thank you iFIXIT for doing what you do. Truly appreciated. Perfect instructions- just perfect!!

tgsavel - Antwort

Thank you for the great guide! I did not want to ship my Mac to official Apple service centre - as I was advised I would need to wait one week for battery replacement and I needed laptop for my daily work. Decided to replace battery on my own. Thanks to this comprehensive guide I made it in 2 hours. I do appreciate clear and comprehensive way author has explained the procedure. Again big thank you! Also useful comments of users are appreciated. Thanks. Andrew
