STEPS:

Tools You Need

For this repair, you will need a pentalobe screwdriver for opening the back panel, a T5 Torx screwdriver for internal screws, isopropyl alcohol (98%) to loosen adhesive, a plastic spudger for safe disconnection of internal cables, and a wide plastic flat-edge pry tool to safely lift the battery without puncturing it.

---

Remove the Bottom Case

• Flip the MacBook over and remove all 10 pentalobe screws using the appropriate screwdriver.
• Carefully pop off the bottom case to reveal the internal components.
• Set the bottom cover aside in a safe place.

---

Disconnect the Battery

• Use a plastic pry tool or your fingernail to disconnect the battery connector from the logic board.
• Gently pull the connector away to ensure it’s completely detached.
• This step is critical to avoid any electrical shorts during the process.

---

Remove the Battery Retention Bracket

• Use the T5 Torx screwdriver to remove the screw holding the center battery retention bracket.
• Lift and remove the retention bracket from the device.
• Set it aside safely for reinstallation later.

---

Disconnect the Trackpad Cable

• Use the plastic spudger to carefully disconnect the trackpad cable from the logic board.
• Trace the cable down and unplug it from the trackpad itself to fully detach it.
• This prevents accidental damage while removing the battery.

---

Remove the Battery Daughter Board Screw

• Using the T5 screwdriver again, remove the screw securing the battery daughter board.
• Gently lift the board to confirm it’s free.
• Set the screw aside for reassembly.

---

Soften the Battery Adhesive

• Apply 98% isopropyl alcohol around the edges of the battery to soak the adhesive strips.
• Let the alcohol sit for a few minutes to loosen the bond.
• This will make the battery removal much easier and safer.

---

Pry Up the Battery

• Use a wide plastic flat-edge pry tool to lift the center battery cell first.
• Avoid using metal tools to prevent puncturing the battery.
• Work your way from the center out to the left and right cells.

---

Remove the Old Battery

• Once all cells are loosened, lift the battery out of the chassis.
• Discard the old battery according to your local regulations.
• Prepare the surface for the new battery installation.

---

Clean the Adhesive Residue

• Soak remaining adhesive strips with isopropyl alcohol to soften them further.
• Use a flat-edge metal pry tool to carefully scrape off the adhesive.
• Ensure the surface is clean and smooth for proper adhesion.

---

Install the New Battery

• Peel off the protective strips on the adhesive backing of the new battery.
• Carefully position and press the battery into place.
• Ensure it sits flat and securely in the chassis.

---

Secure the Battery Board

• Reinstall the screw that holds the battery daughter board using the T5 screwdriver.
• Double-check that the board is firmly attached.
• This step is essential for proper power delivery.

---

Reconnect the Trackpad Cable

• Start by plugging the cable into the trackpad at the bottom of the MacBook.
• Then reconnect the cable to the logic board.
• Be sure the connections are tight and secure.

---

Reinstall the Retention Bracket

• Position the battery retention bracket back in place.
• Secure it using the original screw and the T5 screwdriver.
• Confirm that it’s firmly holding the battery in place.

---

Reconnect the Battery

• Plug the battery connector back into the logic board.
• Press it down gently to ensure a solid connection.
• This re-establishes power to the device.

---

Test the Battery Connection

• Plug in a charger and observe the LED indicator.
• A green light confirms a connection; orange indicates charging.
• Power on the MacBook to verify the battery works.

---

Final Check and Reassembly

• Unplug the charger and confirm the MacBook holds a charge.
• Plug it back in and verify that it resumes charging.
• Once everything is tested, reinstall the bottom case.

---

Reinstall the Bottom Case

• Position the bottom case back onto the MacBook.
