Introduction

Use this guide to safely remove the glued-in battery from your 16” MacBook Pro with the help of an iFixit kit with adhesive remover. The adhesive remover is designed to weaken the glue securing the battery, allowing you to remove it with ease.

iFixit adhesive remover is flammable. Follow this procedure in a well-ventilated area. Do not smoke or work near an open flame.

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 looks puffy or 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.

    • 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:

    • 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.

    @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!

    Thats right! You don't want power running while working on your logic board.

    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.

    BEFORE YOU START: The included torx head stripped off before I was done (and you might need an additional T4) so stop now and go buy a good one. Also they fail to warn you above to get some blue threadlocker ahead of time.

    This command did not work for me and I read that sometime in later 2020 Apple stopped this command from working…any ideas on a work around?

    If you have a damaged screen you can still use a converter from thunderbolt (USB 3) to HDMI and plug your Macbook Pro to your TV as monitor display. Just make sure to chose the right Source (HDMI IN) in your TV. I did it and to make it work I unplug and plug again in my Macbook and so I could disable the Auto boot

    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 - Reply

    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.

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

    result: `AutoBoot %00`

    Marek Polák - Reply

    Running Big Sur 11.6.7 on a 2019 16" MBP, it's "auto-boot". So it's: nvram -p | grep 'auto-boot' to display the current state, the default is true - and then to change it, sudo nvram auto-boot=false which turns it off.

    Ed Mechem -

    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.

    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.

    I didn’t do this. Mine never auto-booted before I replaced the battery. Now it does.

    BEFORE YOU DO ANYTHING - CHECK THE BATTERY!

    I-fixit sent me a bad battery, which I didn’t realize until it was already install. They sent me a new one, but I wasted hours uninstalling and reinstalled.

    Get a volt meter and measure the voltage on the output of the battery pack. If it reads 0 V, SEND IT BACK. It should read over 2 V.

    When I did this from Terminal.app within Recovery Mode, the “sudo” was not recognized but I could invoke it without the sudo part. It seems to have been accepted when looking at “nvram -p”

    johann beda - Reply

    When in Recovery Mode, you already have superuser powers. So you don't need to prefix commands with the sudo command to invoke them with root privileges; you already have them. Do a pwd (print working directory) after opening Terminal in Recovery Mode, and you'll see that you're in the root user's directory.

    I received the battery kit for my 2018 MacBook Pro and as per the above comment from bcardanha - Oct 12, 2021, I checked the voltage on the pads marked + and - . It was zero volts so I panicked a bit.

    I sent a message on the iFixiT Facebook page and I got no reply. I finally found the customer service email for Ifixit Europe and sent them an email voicing my concern as I was not keen to work for couple of hours just to discover that the battery is faulty. I had an almost instant reply on the email (kudos to them) and they adviced me to go ahead and install the new battery as the voltage measured when battery is not connected is not relevant.

    I took a leap of faith and after two hours… the new battery showed 50% charge and everything seems to be working just fine. I am happy it worked.

    After removing the old battery and installing the new battery I powered up the MBP before screwing the bottom on. I discovered the my keyboard would not function. It took a few hours of investigation and frustration that I discovered the track pad power ribbon had become partially dislodged from the trackpad. I was able to see that this through the little machined slot where the battery sat. I had to remove the trackpad to reinsert the power ribbon back into the connector in the trackpad. after reassembling and reinstalling the battery etc the keyboard worked. Just food for thought if your run into the keyboard issue.

    This should be the default. IMO I tell you to power on - not the lid.

    • Completely power off and unplug your MacBook Pro before you start. Close the display and flip the entire laptop upside-down.

    • Use a P5 Pentalobe driver to remove six screws securing the lower case, of the following lengths:

    • Four 3.7 mm screws

    • Two 7.3 mm screws

    • Note how the screws come out at a slight angle—you must reinstall them the same way.

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

  2. MacBook Pro 16" 2019 Battery Replacement, Unclip lower case: step 3, image 1 of 2 MacBook Pro 16" 2019 Battery Replacement, Unclip lower case: step 3, image 2 of 2
    • Press a suction handle into place near the front edge of the lower case, between the screw holes.

    • Pull up on the suction handle just enough to open a small gap under the lower case.

  3. MacBook Pro 16" 2019 Battery Replacement: step 4, image 1 of 3 MacBook Pro 16" 2019 Battery Replacement: step 4, image 2 of 3 MacBook Pro 16" 2019 Battery Replacement: step 4, image 3 of 3
    • Slide the corner of an opening pick into the gap you just created underneath the lower case.

    • Slide the opening pick around the nearest corner and then halfway up the side of the MacBook Pro.

    • This releases the first of the hidden clips securing the lower case. You should feel and hear the clip pop free.

    I recommend being careful while sliding as you can scratch the speaker. The actual clip is about halfway up the side, whereas the speaker is closer to the front (further from the hinge). So stay very shallow with just the tip of the pick until you get halfway up the side.

    • Repeat the previous step on the other side, using an opening pick to to release the second clip.

    Same advice that I gave for the other side — be careful not to scratch the speaker which is close to the bottom. Keep the pick shallow until you get halfway up the side.

    • Lift the front edge of the lower case (the side opposite the display hinge) enough to slide your fingertips underneath and get a good grip on it.

    • Two additional hidden clips near the middle of the cover should pop free at this point, if they haven't already.

    • Don't lift more than an inch or so, and don't try to remove the lower case yet.

    • Pull firmly to slide the lower case towards the front edge of the MacBook (away from the hinge area) to separate the last of the clips securing the lower case.

    • Pull first at one corner, then the other.

    • Pull to the side—not up.

    • This may require a lot of force.

    This was made a lot easier by using a lever in the hinge area in combination with pulling. The amount of force required was more than the grip I could get on the metal allowed for my macbook.

    • Remove the lower case.

    • To reinstall the lower case:

    • Set it in place and align the sliding clips near the display hinge. Press down and slide the cover toward the hinge. It should stop sliding as the clips engage.

    • When the sliding clips are fully engaged and the lower case looks correctly aligned, press down firmly on the lower case to engage the four hidden clips underneath. You should feel and hear them snap into place.

    • Peel up (but don't remove) the rubber vibration damping strip from the adhesive holding it to the fan.

    • If needed, apply mild heat with an iOpener, hair dryer, or heat gun to soften the adhesive and make the dampers easier to separate.

    • Repeat for the other adhesive strip on the opposite fan.

  64. MacBook Pro 16" 2019 Battery Replacement: step 65, image 1 of 2 MacBook Pro 16" 2019 Battery Replacement: step 65, image 2 of 2
    • The logic board assembly is a tight fit, but you can make it easier to remove by inserting a spudger under the left edge and levering it up slightly.

    • There should be no resistance as you remove the logic board. Check all cables carefully and hold them out of the way if needed so they don't snag on the board.

  65. MacBook Pro 16" 2019 Battery Replacement: step 66, image 1 of 1
    • Lifting from the left side, remove the logic board.

  66. MacBook Pro 16" 2019 Battery Replacement: step 67, image 1 of 2 MacBook Pro 16" 2019 Battery Replacement: step 67, image 2 of 2
    • When reinstalling the logic board assembly:

    • Feed the antenna cable bundle through the gap between the logic board and heat sink, and make sure it lines up correctly as you lower the board into place.

    • Verify that no cables get trapped under the board as you install it. Check each of the fifteen marked locations carefully.

  67. MacBook Pro 16" 2019 Battery Replacement, Battery: step 68, image 1 of 1
    • Use a T5 Torx driver to remove the 5.1 mm screw securing the battery board.

    • The liquid adhesive remover provided in your kit can damage the antireflective coating on your MacBook Pro's display, as well as the plastic keyboard keys.

    • To protect your display, place a sheet of aluminum foil between the display and keyboard and leave it there while you work.

    • Additionally, use painter's tape to seal off the area under the trackpad as best you can. Optionally, you may also layer an absorbent towel directly underneath the trackpad area to soak up any excess adhesive remover.

  69. MacBook Pro 16" 2019 Battery Replacement: step 70, image 1 of 2 MacBook Pro 16" 2019 Battery Replacement: step 70, image 2 of 2
    • To control the flow of adhesive remover, raise the back edge (hinge side) of your MacBook Pro a few inches using a book or foam block.

  70. MacBook Pro 16" 2019 Battery Replacement: step 71, image 1 of 2 MacBook Pro 16" 2019 Battery Replacement: step 71, image 2 of 2
    • Now that your MacBook Pro is fully prepped, it's time to prep yourself.

    • iFixit adhesive remover contains acetone, a mild skin and eye irritant.

    • Wear eye protection when handling and applying the adhesive remover. (Eye protection is included in your kit.)

    • Do not wear contact lenses without eye protection.

    • Protective gloves are also included in your kit. If you are concerned about possible skin irritation, put your gloves on now.

  71. MacBook Pro 16" 2019 Battery Replacement: step 72, image 1 of 3 MacBook Pro 16" 2019 Battery Replacement: step 72, image 2 of 3 MacBook Pro 16" 2019 Battery Replacement: step 72, image 3 of 3
    • Pull off the black rubber stopper from your bottle of adhesive remover.

    • Twist to loosen or remove the bottle cap before you cut the applicator tip.

    • This unseals the bottle and allows the pressure to equalize before you cut the applicator tip. If you skip this step, the adhesive remover may spray out unexpectedly when the tip is cut.

    • Use scissors to cut off the sealed tip of the applicator.

    • Cutting close to the narrow tip will give you better control so you can apply the adhesive remover in small amounts.

    • Twist and close the bottle cap securely before you proceed further.

  72. MacBook Pro 16" 2019 Battery Replacement: step 73, image 1 of 2 MacBook Pro 16" 2019 Battery Replacement: step 73, image 2 of 2
    • Apply a few drops of adhesive remover underneath the two battery cells on the right, starting along the edge nearest the fan.

    • You don't need to use very much. The small bottle contains more than twice the amount of solvent needed to remove all the battery cells.

  73. MacBook Pro 16" 2019 Battery Replacement: step 74, image 1 of 2 MacBook Pro 16" 2019 Battery Replacement: step 74, image 2 of 2
    • Add a few more drops of adhesive remover in between the two battery cells on the right, so that it flows down underneath the lower battery cell.

    • Wait about two minutes for the liquid adhesive remover to penetrate and weaken the battery adhesive before you proceed to the next step.

  74. MacBook Pro 16" 2019 Battery Replacement: step 75, image 1 of 3 MacBook Pro 16" 2019 Battery Replacement: step 75, image 2 of 3 MacBook Pro 16" 2019 Battery Replacement: step 75, image 3 of 3
    • After a couple minutes, insert one corner of a plastic card underneath the battery, starting from the lower edge of the bottom, right-most cell.

    • This shouldn't require much force. If you have trouble, apply more adhesive remover and give it 2-3 additional minutes to penetrate.

    • Try not to deform the battery. A damaged or punctured battery can leak dangerous chemicals and/or catch fire.

    • Wiggle the card from side to side and slide it all the way underneath both battery cells.

    • Lift the cells to fully separate the adhesive, but don't try to remove them from your MacBook yet.

    • Leave the plastic card temporarily underneath the cells to prevent the adhesive from re-bonding as you proceed to the next step.

  75. MacBook Pro 16" 2019 Battery Replacement: step 76, image 1 of 3 MacBook Pro 16" 2019 Battery Replacement: step 76, image 2 of 3 MacBook Pro 16" 2019 Battery Replacement: step 76, image 3 of 3
    • Switch to the left side of the MacBook Pro, and repeat the previous step to separate two more battery cells.

    • Leave the second plastic card in place temporarily.

  76. MacBook Pro 16" 2019 Battery Replacement: step 77, image 1 of 3 MacBook Pro 16" 2019 Battery Replacement: step 77, image 2 of 3 MacBook Pro 16" 2019 Battery Replacement: step 77, image 3 of 3
    • Apply a few drops of adhesive remover along the top edges of the two center battery cells.

    • There are openings in the chassis underneath these two cells, which allow the adhesive remover to leak through and may prevent it from fully penetrating.

    • Be mindful of leaks, and apply more adhesive remover along the side edges if needed.

  77. MacBook Pro 16" 2019 Battery Replacement: step 78, image 1 of 3 MacBook Pro 16" 2019 Battery Replacement: step 78, image 2 of 3 MacBook Pro 16" 2019 Battery Replacement: step 78, image 3 of 3
    • After a couple minutes, retrieve your first plastic card and insert one corner under the top edge of one of the center battery cells.

    • Wiggle it from side to side and slide it underneath the battery cell until all the adhesive separates.

    • If you have trouble, don't use excessive force and don't deform the battery. Apply more adhesive remover and try again, or skip down two steps for an alternate method.

  78. MacBook Pro 16" 2019 Battery Replacement: step 79, image 1 of 3 MacBook Pro 16" 2019 Battery Replacement: step 79, image 2 of 3 MacBook Pro 16" 2019 Battery Replacement: step 79, image 3 of 3
    • Retrieve your second plastic card and repeat the previous step to separate the remaining center battery cell.

  79. MacBook Pro 16" 2019 Battery Replacement: step 80, image 1 of 1
    • If you had trouble getting the card underneath any of the battery cells, try working a piece of floss or wire underneath the battery cell and pull it side-to-side in a sawing motion to separate the adhesive.

    • Wear thick gloves or wrap the floss around a couple of driver handles so as not to hurt your fingers.

  80. MacBook Pro 16" 2019 Battery Replacement: step 81, image 1 of 2 MacBook Pro 16" 2019 Battery Replacement: step 81, image 2 of 2
    • Lift and remove the battery.

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

    • Peel off any large strips of adhesive using tweezers or gloved fingers.

    • Scrape away any remaining chunks of 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 the chassis is clean and ready for your new battery.

    • This can take quite a bit of work, so be patient.

    • Double-check the fit and alignment of your new battery before sticking it down.

    • If your battery came with adhesive pre-installed on the bottom, flip it over and carefully peel away the 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 keep your battery in place.

    • 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.

Amazing. This is truly thorough, and as soon as this battery starts to fail, will come back here. Nice work documenting a whole assembly line.

If I want to replace my fans, it looks like I can follow this guide to step 66 and then just figure it out from there? Is there a guide somewhere on this? Thanks!

Matt - Reply

You can do as you wrote for replacing only the fan. Ther’s nothing more to know about it.

Daniele Carminati -

I see that the MacBook Pro 13 logic board remains in place in iFixit battery replacement guide. Is there any reason why in the MacBook Pro 16 the logic board cannot remain in place while removing and reinstalling the battery?

andremengatti - Reply

Yes, there are two battery cables running under the logic board, clearly visible at step 68. No way to put the battery back with the logic board in place.

I recently did the 15” 2017 Macbook Pro battery replacement and that seemed more difficult than this one due to the speaker connectors. In my opinion, this 16” replacement can be marked as Moderate.

Cristian Caprar -

Great guide! Wow! Definitely not for the faint of heart! Thanks Carsten!
