Remove the wide head 6.4 mm T6 Torx screw securing the battery connector to the logic board assembly.

Carefully lift the battery connector board up off the logic board.

It is recommended to bend the battery cables just slightly, to keep the board suspended up above the logic board and out of the way.

Grasp the Interposer with tweezers.

• An interposer is the name for an interface that links one electrical connection to another. In this repair, it is the board connecting the battery to logic board.

Lift the Interposer off the logic board and remove it.

• Removing this board will ensure that the battery remains disconnected throughout your repair, preventing your computer from accidentally powering on. It's also a good idea to take it out so it doesn't fall out unexpectedly.

Wedge the flat end of a spudger beneath the left side of the I/O board data cable connector.

Gently twist the spudger to disconnect the I/O board data cable connector from its socket on the logic board.

Lift and remove the I/O board data cable from the MacBook Pro.

Use the flat end of a spudger to pry the SSD cable connector up from its socket on the logic board.

Move the SSD cable connector out of the way.

Wedge the flat end of a spudger beneath the right speaker cable connector.

Use your thumb or finger to bend the plastic spring bar on the SSD tray, freeing the two clips at the front side of the device.

While holding the spring bar depressed, tilt the SSD assembly up out of its cavity.

Remove the SSD assembly from the upper case.

Remove three 2.2 mm T5 Torx screws from each side of the battery (six screws total).

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

Now that your MacBook Pro is fully prepped, it's time to prep yourself.

Pull off the black rubber stopper from your bottle of adhesive remover.

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.

Apply a few drops of adhesive remover evenly under the edge of the leftmost battery cell.

• 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.

Wait 2-3 minutes for the liquid adhesive remover to penetrate underneath the battery cell before you proceed to the next step.

Insert the flat edge of a spudger or plastic card underneath the leftmost battery cell.

Run your tool along the bottom perimeter of the battery cell and lift to begin separating the adhesive.

Insert the spudger along the left-hand side of the leftmost battery cell.

Run the spudger up along the left side of the leftmost battery cell.

Slightly pry the leftmost battery cell to release it from 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.
• Carefully wedge a spudger or plastic card inwards, being careful to not damage the battery, and separate the battery cell from the adhesive securing it to your MacBook Pro.

Insert the flat end of a spudger underneath the larger leftmost battery cell.

Carefully wedge the spudger inwards, being careful to not damage the battery cells.

Pry the larger leftmost battery cell up off the upper case.

Grasp the battery cells and gently move (but do not remove) them from their recess in the upper case.

Leave the battery cells resting on top of the upper case as shown in the third picture.

Switch sides and repeat the above procedure for the two battery cells on the right-hand side of the MacBook Pro.

• Remember to add a small amount of liquid adhesive remover under each battery cell, and wait 2-3 minutes for it to penetrate before prying up the cell.
• Be careful not to puncture or otherwise damage the battery cells.

Lift the battery as a whole up out of the upper case, and remove the battery.

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%.
