The liquid adhesive remover provided in your kit can affect the antireflective coating on your MacBook Pro's display.

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

With the front edge of the MacBook Pro facing you, lift the right side and prop it up at a slight angle, using a sturdy foam block or book.

In the following steps, you'll apply liquid adhesive remover to the right (outer) edge of the battery. Keeping this side of the MacBook Pro elevated will help the adhesive remover flow underneath the battery.

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

iFixit adhesive remover contains acetone, a mild skin and eye irritant.

Wear eye protection when handling and applying the adhesive remover. (Eye protection is included in your kit.)

'''Do not''' wear contact lenses without eye protection.

Protective gloves are also included in your kit. If you are concerned about skin irritation, put your gloves on now.

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.'''

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.

Twist and close the bottle cap securely before you proceed further.

Apply a few drops of adhesive remover evenly along the elevated edge of the outer right 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.

Slide one corner of a [product|IF145-101|plastic card] under the outer edge of the battery cell.

It may help to gently twist the card to open up a slight gap between the battery cell and the MacBook Pro's case.

Slide the card farther underneath the battery cell to separate it from the adhesive securing it to the MacBook Pro's upper case.

Lift the battery cell to separate it from the MacBook Pro's upper case, but don't try to remove it.

Leave the plastic card underneath the battery cell to prevent it from re-adhering as you proceed to the next step.

Apply a few drops of adhesive remover evenly along the elevated edge of the next battery cell.

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

Slide one corner of your plastic card underneath the second battery cell.

Push the card underneath the second battery cell, and slide it side to side to separate the adhesive underneath.

Leave the plastic card underneath both battery cells (or [https://d3nevzfk7ii3be.cloudfront.net/igi/HdJgFHfXyTbjfOTD.huge|flip them over|new_window=true]) to prevent them from re-adhering as you proceed to the next step.

It's time to switch sides. Remove your book or foam block and place it under the opposite side of your MacBook Pro.

Repeat the procedure from the prior steps to separate the two battery cells on this side:

Apply your adhesive remover to the elevated edge of the outer left battery cell, and wait 2-3 minutes for it to penetrate.

Work one corner of a plastic card underneath the battery cell, and slide the card fully underneath the battery cell to separate it.

Do the same for the adjacent cell.

Leave your plastic card in place or flip the battery cells over to prevent them from re-adhering during the following steps.

With the left edge of your MacBook Pro still propped up, apply a few drops of adhesive remover down the center line between the two middle battery cells.

Wait 2-3 minutes for the adhesive remover to penetrate before you continue.

Slide one corner of a plastic card between the middle two cells, and under the elevated edge of the center-right battery cell.

Slide the card farther underneath the battery cell to slice through the adhesive securing it in place.

Don't try to fully separate this battery cell yet. Leave your plastic card in place to prevent it from re-adhering.

Flip the two de-adhered right-hand battery cells over the front edge of the MacBook Pro, if you haven’t already. This will allow access to the outside edge of the center cell.

Push one corner of a plastic card below the plastic battery frame and underneath the remaining adhered edge of the lower center cell.

Do not pry along the edge nearest the battery connector, or you risk damaging the keyboard ribbon cable.

Slide your card all the way under the battery cell, and leave it to prevent the battery cell from re-adhering.

Remove the first plastic card that you inserted under the center-right battery cell.

Push the other card in a little further and leave it in place to prevent the battery cell from re-adhering as you continue.

Remove your book or foam block.

With the front edge of the MacBook Pro facing you, lift the right side and prop it up once again.

Apply a few drops of adhesive remover between the two center battery cells, so that it flows underneath the remaining battery cell.

Wait 2-3 minutes for the adhesive remover to penetrate before you continue.

Slide one corner of a plastic card under the elevated edge of the final battery cell.

Push the card farther underneath the battery cell to slice through the adhesive securing it in place.

Don't try to fully separate this battery cell yet. Leave your plastic card in place to prevent it from re-adhering.

If you haven't already done so, lift and flip the two outer left battery cells to clear access to the outside edge of the final battery cell.

Repeat the process you used on the center-right battery cell to finish separating the adhesive on the center-left cell:

Push one corner of a plastic card below the plastic battery frame and underneath the remaining adhered edge of the final battery cell.

Slide your card all the way underneath the battery cell, and leave it to prevent the battery cell from re-adhering.

Remove the first card that you inserted under the final battery cell.

With one plastic card underneath each of the two center battery cells, twist and lift both cards to fully separate the battery cells, together with the plastic frame and battery board, from the MacBook Pro.

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.

If you notice any unusual behavior or problems after installing your new battery, you may need to [https://support.apple.com/en-gb/HT201295|reset your MacBook Pro's SMC|new_window=true].
