Introduction
Use this guide to replace the upper case. This procedure involves using adhesive remover to remove the battery. Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.
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.

Run your tool along the bottom perimeter of the battery cell and lift to begin separating the adhesive.
-
-
-
Repeat the above steps to separate the adjacent battery cell from its adhesive:
-
Apply a few drops of liquid adhesive remover under the battery cell.
-
Wait 2-3 minutes for the adhesive remover to penetrate and soften the adhesive.

-
-
Lift the battery as a whole up out of the upper case, and remove the battery.
-
With a little luck, you can slowly pull out each strip of adhesive with your fingers.
