Introduction

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.

For your safety, discharge 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.

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. Power on your Mac and launch Terminal. Copy and paste the following command (or type it exactly) into Terminal:

  • Press [return]. If prompted, enter your administrator password and press [return] again.

  • 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

  • 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”.

Insert one corner of an opening pick into the space between the lower case and the chassis. Slide the opening pick around the nearest corner and halfway up the side of the case. This releases the first of the hidden clips securing the lower case to the chassis. You should feel and hear the clip pop free.

Insert your opening pick once again under the front edge of the lower case, near one of the two centermost screw holes. Give the pick a firm twist to pop free the third clip securing the lower case to the chassis. Repeat this procedure near the other of the two centermost screw holes, popping the fourth clip free.

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.

Apply a few drops of adhesive remover underneath the front edge of the battery cell that lies 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.

Gently work the card deeper under the battery cell to break up the adhesive securing it in place. This should not require much force—the adhesive remover does most of the work. If you aren't able to get your card under the battery cell, apply a bit more adhesive remover as instructed above and wait 2-3 minutes before trying again.

  • 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 battery before using it: allow it to drain overnight, then charge it to 100% and drain it again until your MacBook Pro shuts down automatically. Charge it again and use it normally.

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

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