Use this guide to safely remove the glued-in battery from your MacBook Pro with the help of an iFixit battery replacement kit. The adhesive remover in your kit will dissolve the adhesive securing the battery, allowing you to remove it with ease.

Apple issued a battery recall for this model in June of 2019—so before replacing your battery, you can check to see if you are eligible to receive a replacement for free from Apple.

iFixit adhesive remover is highly 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 your speakers if it comes in contact with the plastic speaker enclosures. Therefore, this guide instructs you to remove the speakers before proceeding to the battery. Removing the speakers requires also removing several other components including the logic board.

Paso 29  ¶ 

  • 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.
