Introduction
Use this guide to safely remove the glued-in battery from your MacBook Pro with the help of an iFixit kit with adhesive remover. The adhesive remover is designed to weaken the glue securing the battery, allowing you to remove it with ease.
iFixit adhesive remover is flammable. Follow this procedure in a well-ventilated area. Do not smoke or work near an open flame.
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 looks puffy or swollen, take extra precautions.
Note: The solvent used to dissolve the battery adhesive can damage certain plastics. Follow all instructions and take care where you apply the adhesive remover.

If the cover doesn't peel up easily, apply mild heat with an iOpener, hair dryer, or heat gun to soften the adhesive underneath, and try again.

Additionally, use painter's tape to seal off the area under the trackpad as best you can. Optionally, you may also layer an absorbent towel directly underneath the trackpad area to soak up any excess adhesive remover.

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

Tool used on this step:Plastic Cards$2.99
-
After a couple minutes, insert one corner of a plastic card underneath the battery, starting from the lower edge of the bottom, right-most cell.
-
Wiggle the card from side to side and slide it all the way underneath both battery cells.
-
Lift the cells to fully separate the adhesive, but don't try to remove them from your MacBook yet.
-
Leave the plastic card temporarily underneath the cells to prevent the adhesive from re-bonding as you proceed to the next step.

-
Tool used on this step:Tweezers$4.99
-
Lift and remove the battery.
-
Peel off any large strips of adhesive using 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.

Tool used on this step:Tesa 61395 Tape$12.99
-
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 Tesa 61395 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.
-
-
-
After your battery is properly positioned and installed, peel off and discard the clear plastic liner from the top.
-
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%.

This is an awesome guide. My girlfriend’s MacBook Pro was diagnosed with a logic board failure by the repair centre. The repair cost was going to be more than a new 6-core Mac Mini.
I tinkered with the device, and thanks to the help of the iFixit community, a battery fault was diagnosed. Installed a new battery and the problem was solved!
Everything went perfectly. Thanks for the great guide :)
Hello I bougth the battery on this site my model is A1707, I followed the procedure and when I turned it on it stays in 1% and says condition: Replace now… what can I do?
Hi Rafael, make sure you’ve calibrated your battery first. If that doesn’t fix anything and you’re using an iFixit battery, contact our customer support team and they’ll help you out. Otherwise you can post your question on the Answers Forum—there are a bunch of experts there that can offer advice.
My late 2016 model MBP’s battery had swollen after 3 years (2 months out of warranty). Apple wanted $850 to send it in and replace it. I purchased a new battery and it’s kit for a fourth of the price from iFixit. 2.5 hours later, and everything seems to be working smoothly. The guide was spot on.
