MacBook Pro Retina 15 inch (Mid 2015)Battery Replacement
- The adhesive remover is highly flammable. Please work in a clear, open and well-ventilated area.
- The solvent used to dissolve the battery adhesive might be damaging to certain plastics such as the MacBook Pro’s plastic speaker enclosures. Take extra care when applying the solvent.
- Allow the battery to fully discharge before starting this repair. A charged lithium-ion battery can create a dangerous fire if accidentally punctured.
Remove the following P5 pentalobe screws:
- Eight x 3.0 mm (red)
- Two x 2.3 mm (yellow)
Lifting from the edge nearest the clutch cover, lift the lower case off the MacBook Pro.
Set the lower case aside.
Peel back the warning label covering the battery connector.
Gently pry the battery connector straight up out of its socket on the logic board.
Bend the battery cables back and out of the way, ensuring that the battery connector doesn't accidentally make contact with the logic board.
Remove the two 2.2 mm Torx T5 screws securing the touchpad cable connector cover to the logic board.
Remove the cover.
Use the flat end of a spudger to disconnect the touchpad cable connector from its socket in the logic board.
Use the tip of a spudger to flip up the black locking tab on the trackpad ribbon cable ZIF connector.
Remove the trackpad ribbon cable.
Remove the two 3.2 mm T5 Torx screws securing the battery board.
Place a sheet of aluminium foil covering the entire display, between the display and the keyboard. The adhesive remover might damage the anti-reflective coating of the display.
If you are using the adhesive remover, follow these instructions.
*If you are using a hair dryer, jump to step 12.
The adhesive remover contains acetone, a mild skin and eye irritant. Ensure that you have ensured the following:
- Work in a well-ventilated area.
- Wear protective gloves if you are concerned about skin irritation.
- Apply a few drops of adhesive remover evenly under the edge of the rightmost battery cell.
- Wait 2-3 minutes for the liquid adhesive remover to penetrate the adhesive under the battery before proceeding.
- Use more adhesive remover if needed but apply only a few drops at a time to prevent it from seeping into other components.
Heat the rightmost battery cell gently with a hair dryer until it is uncomfortable to touch to warn and soften the section of adhesive securing the battery.
Ensure that you apply the heat gently as too high heat may cause the battery to be flammable.
Once the adhesive has sufficiently weakened, slide a plastic card between the rightmost battery cell, cutting the adhesive between the battery and the case.
If there is significant resistance, you may either apply a few more drops of adhesive remover or gently heat the section again.
Throughout this procedure, take extra care not to damage any of the battery cells. A damaged lithium-ion battery may leak dangerous chemicals and/or catch fire. Use only plastic pry tools.
Use the plastic card to pry the rightmost battery cell up from the rear case.
Repeat the procedure with the adjacent battery cell:
Weaken the adhesive either by using the adhesive remover or heating the section gently.
Push a plastic card about an inch between the battery cell and the case, and slowly pry the cell up to separate the adhesive.
Repeat step 11 to 15 on the leftmost 2 battery cells.
To separate the adhesive securing the middle 2 cells, apply a few more drops of adhesive remover to each cell.
It may help to elevate one side of your device so that the adhesive remover flows in the correct direction underneath the battery cell.
Insert the card about an inch between both of the battery cells and the case, one at a time, separating the adhesive between the cell and the case.
Pry out the middle cells
Remove the battery.
