Use a T5 Torx driver to remove the two 3.2 mm screws from the battery board.

The liquid adhesive remover provided in your kit can cause damage if it contacts the MacBook Pro's display or keyboard.

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

Additionally, use some tape and/or foil to seal off the area under the trackpad. Optionally, you may also layer an [https://d3nevzfk7ii3be.cloudfront.net/igi/XDsygIdWSReZvSyK.full|absorbent towel|new_window=true] directly underneath the trackpad area to soak up any excess adhesive remover.

Before removing the battery, it's important to protect the speakers on either side. The speakers are glued down just like the battery—so if the liquid adhesive remover gets under the speakers, they may come loose and rattle after your repair.

Cut a length of packing tape or painter's tape, and slide one edge between the battery and the speaker on the left side.

Press all along the edge of the tape with your spudger to stick it securely to the MacBook Pro's aluminum case, sealing off the speaker from the battery.

Be careful not to poke or puncture the battery.

Fold the tape over and lightly adhere it to the speaker to keep it out of the way.

The foam bumpers on top of the speaker may tear when peeling the tape off. Don't press the tape directly onto the bumpers.

Repeat the previous two steps on the opposite side in order to seal off the other speaker from the battery.

To control the flow of adhesive remover and direct it away from the speaker, raise the right edge of your MacBook Pro a few inches using a book or foam block.

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 possible 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 underneath the far 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 about two minutes for the adhesive remover to penetrate and soften the battery adhesive before you proceed to the next step.

After a couple minutes, insert one corner of a [product|IF145-101|plastic card] underneath the far right battery cell, starting from the front edge.

This shouldn't require much force. If you have trouble, apply more adhesive remover and give it 2-3 additional minutes to penetrate.

Try not to deform the battery. A damaged battery can leak dangerous chemicals and/or catch fire.

Wiggle the card from side to side and slide it all the way under the battery cell.

Lift to fully separate the adhesive, but don't try to remove the battery cell yet.

Leave the plastic card temporarily underneath the cell to prevent it from re-adhering while you continue.

If you have difficulty getting the card underneath any of the battery cells, try working a piece of floss or wire underneath the battery cell. Pull it side-to-side in a sawing motion to separate the adhesive.

Wear thick gloves or wrap the floss around a couple of driver handles so as not to hurt your fingers.

Repeat the last few steps to separate the far left battery cell.

Begin by elevating the left side of the MacBook Pro to direct the flow of adhesive remover away from the speaker.

Apply a few drops of adhesive remover under the far left battery cell, and wait about two minutes for it to penetrate.

Slide one corner of a plastic card underneath the far left battery cell, and carefully separate the adhesive holding it in place.

Leave the plastic card temporarily underneath the cell to prevent it from re-adhering while you continue.

Next, raise the back edge of your MacBook Pro to direct the flow of adhesive remover away from the keyboard/logic board area.

Apply a few drops of adhesive remover under each of the remaining three battery cells.

There are openings in the aluminum case underneath these cells, so some of the adhesive remover may leak out instead of penetrating underneath the battery.

Be mindful of leaks, and apply more adhesive remover in the following steps if needed.

Wait about two minutes before you continue.

The remaining two smaller battery cells each sit on a slightly raised portion of the MacBook's aluminum frame.

Slide a plastic card all the way underneath the far left battery cell—which you already separated in the previous steps—and then insert it carefully between the remaining left-side battery cell and the MacBook Pro's aluminum case.

Use your plastic card to fully separate the remaining battery cell on the left side.

Leave your plastic card in place temporarily to prevent the left-side battery cells from re-adhering.

Repeat the previous two steps to separate the remaining battery cell on the right.

The final battery cell can be more difficult to remove. If needed, apply more adhesive remover to make the job easier.

Slide the corner of one of your plastic cards underneath the top edge of the large center battery cell.

Wiggle the card from side to side and slide it underneath the battery cell to fully separate the adhesive holding it in place.

Remove the battery.

Before installing a new battery, remove all remaining adhesive from the MacBook Pro's case.

Peel off any large strips of adhesive using [product|IF145-020|tweezers] or gloved fingers.

Scrape away any remaining chunks of adhesive with a plastic tool, and clean the underlying areas with adhesive remover or isopropyl alcohol. Wipe in one direction (not back and forth) until the chassis is clean and ready for your new battery.

This can take quite a bit of work, so be patient.

When you're done, carefully [https://d3nevzfk7ii3be.cloudfront.net/igi/efNOlQed6oPpmimH.full|remove the protective tape|new_window=true] from the speakers.

Double-check the fit and alignment of your new battery before sticking it down.

Be mindful of the [https://d3nevzfk7ii3be.cloudfront.net/igi/esXkLWGcE6MS4nUY.full|battery data cable|new_window=true] and make sure it doesn't get pinched or trapped under the battery board.

If your battery came with adhesive pre-installed on the bottom, flip it over and carefully peel away the liner to expose the adhesive. If your battery did not come with adhesive, apply a thin double-sided adhesive tape such as [https://www.ifixit.com/Store/Tools/Tesa-61395-Tape/IF317-072-4|Tesa 61395|new_window=true] to keep your battery in place.

Carefully position the battery and set it into place.

Press and hold each cell firmly for 5-10 seconds to secure it to the lower case.
