MacBook Pro (14-inch PROLED XDR, M5 Pro or M5 Max) Battery Reassembly
Repair procedure with reassembly steps.
Before You Begin
Warning
Read Battery Safety and follow workspace and battery handling guidelines before you begin.
Don’t connect the computer to an external power source during repair.
A battery should be replaced only by individual technicians with the knowledge and experience to repair electronic devices. Improper battery replacement, improper handling of parts, or failure to follow the provided instructions could result in fire, injury, data loss, or damage to the device, parts, or other property.
If the battery is dented, expanded, punctured, or otherwise physically damaged, stop the repair. Don’t remove the battery from the device. Replace the top case with a new top case with battery and keyboard.
Don’t reuse or reinstall a loose battery or a battery that has been removed. Replace it with a new battery.
Remove any protective case from the computer.
Caution
The battery contains six individual battery cells connected by a black frame. Don’t bend or flex the black frame.
When removing battery adhesive strips, don’t press parts in the top case for leverage. Use only the aluminum enclosure if you need to brace yourself while pulling the adhesive strips.

Reassembly
Warning: Use the Battery Discharge Tool to verify that the battery is discharged to 30 percent or less.
Position the computer with the trackpad flex cable closest to you.
Install the battery alignment pins in the front left and right corners of the top case. Hand-tighten the alignment pins.
Ensure that the trackpad flex cable is moved out of the way.
Open the replacement battery shipping box and remove the cardboard insert.
Remove the clear plastic packaging containing the replacement battery from the box and turn it over so the blue-and-pink adhesive release liner faces up and the battery alignment pin holes are positioned closest to the computer (1). Then place the packaging and battery on the table between you and the computer.
Grasp the two corners of the clear plastic packaging as shown and carefully pull them apart. Remove the top of the plastic packaging and set it aside.
- Caution: Gently pull apart the packaging to avoid damaging the battery.
Gently peel the blue-and-pink adhesive release liner off the battery as shown.
- Caution: Don’t remove the clear liner located underneath the battery yet. You’ll use this liner to align the battery during installation.
Lift the battery from the plastic packaging by holding the clear liner on each side. Then turn the battery over so the liner is on top and the battery alignment pin holes are positioned closest to you.
- Caution
While lifting, pull each side of the liner outward to keep the battery from sagging or bending, to protect the connections between battery cells, and to avoid damaging the battery.
Don’t touch the battery adhesive to the ESD-safe mat, computer parts, or tools before installing the battery.
Keeping the trackpad flex cable out of the way, tilt down the edge of the battery facing away from you and slide it under the battery management unit tab. Position the alignment holes on the clear liner over the battery alignment pins on the computer. Then lower the clear liner onto the alignment pins and the battery into the top case.
Important: Press the alignment holes on the clear liner down onto the alignment pins as you lower the battery to ensure proper alignment.
Lightly press down on the foam above each battery cell to begin to adhere the battery adhesive to the top case.
- Caution: Don’t press hard on the battery. Don’t press on the edges of the battery cells.
Pick up the computer and fully open the display. Then place the computer keyboard-side down on a clean surface with the display hanging down over the edge of the table.
- Caution: Ensure that you complete this step to avoid damaging the display while using the adhesive activation roller.
Starting with the left end of the clear liner, gently peel the liner off the battery.
- Caution: The adhesive on the liner is strong. Don’t allow the battery to lift up from the top case. You may need to gently hold down the battery as you peel the liner.
Important: Don’t remove the blue liners beneath the clear liner.
Position the press plate so the side with six battery-cell depressions faces up. Align the battery press plate over the battery alignment pins as shown. Then lower the press plate onto the battery.
Hold both handles of the adhesive activation roller and position it over battery cell 1. Then align the roller with the bottom edge of the cell as shown.
Important: Refer to the Adhesive Activation Roller Operating Manual for detailed instructions on using the adhesive activation roller.
Press down on the adhesive activation roller so the orange stripe on the roller pin aligns with the middle of the white band.
Starting at the left edge of the battery cell as shown, roll the adhesive activation roller across to the right edge of the cell. Then roll back to the left edge of the cell. This is one cycle. Complete five cycles for a total of 10 passes.
Repeat steps 14 through 16 for battery cells 2, 3, and 4. Then continue to step 18.
Hold the adhesive activation roller with both hands and position it over battery cell 5. Then align the roller with the left edge of cell 5 as shown.
Press down on the adhesive activation roller so the orange stripe on the roller pin aligns with the middle of the white band.
Starting at the top edge of the battery cell, roll the adhesive activation roller to the bottom edge of the cell. Then roll back to the top edge of the cell. This is one cycle. Complete five cycles for a total of 10 passes.
Align the adhesive activation roller with the right edge of battery cell 5 as shown.
Press down on the adhesive activation roller so the orange stripe on the roller pin aligns with the middle of the white band.
Starting at the top edge of the battery cell, roll the adhesive activation roller to the bottom edge of the cell. Then roll back to the top edge of the cell. This is one cycle. Complete five cycles for a total of 10 passes.
Repeat steps 18 through 23 for battery cell 6. Then continue to step 25.
Lift the battery press plate off the battery and set it aside.
Pick up the computer and close the display. Position the computer display side down on the table with the hinges facing away from you.
Remove the liner from cell 1 by grasping the blue tab in the upper-left corner and peeling it off. Then repeat for cells 2, 3, 4, 5, and 6.
Unscrew the battery alignment pins and remove them from the top case. The alignment pins can be reused.
Place the battery cover on the battery and press down on the black tabs to lock them in place.
Complete the reassembly steps in Battery Management Unit Flex Cable Reassembly to reinstall the flex cable on the replacement battery. Then continue to step 31.
Set the torque value on the 10–34 Ncm adjustable torque driver to 16 Ncm. Then use the adjustable torque driver and 5IP bit to reinstall the 5IP screw (923-15329) into the battery assembly.
