Introduction

Follow these instructions to safely remove the glued-in battery from your MacBook Pro using an iFixit kit with adhesive remover. The liquid solvent in the kit dissolves the adhesive securing the battery, allowing you to remove it more easily.

iFixit adhesive remover is flammable—use it in a well-ventilated area, and 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 be very dangerous 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.

  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. 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

    • 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 4.7 mm screws

    • Two 6.6 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. 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.

    • Make sure the liner doesn't accidentally pull off any of the black battery component coverings. If needed, use tweezers to hold them in place as you peel off the liner.

    • 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's SMC.

Conclusion

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

Hey, is it possible to replace battery without removing a logic board? It was possible on 2017 models.

@webcoder It’s similar to the 2017 design. I’m not sure how you’d replace the battery in either model without removing the board first, since the battery cables are routed underneath the board.

Where can I buy the battery? It is not available for iFixit?
