• Drain the battery below 25% before you start on this repair. A charged lithium-ion battery can catch fire or explode if punctured or damaged
• These MacBook Pros can power on by themselves when the lid opens or a charger is connected. On macOS Sequoia or later, run sudo nvram BootPreference=%00 in Terminal (undo afterwards with sudo nvram -d BootPreference). Power down, and on older macOS keep the lid closed until the battery is disconnected
• The P5 pentalobe, T3 and T5 Torx screwdrivers you need are included in the box with this battery.
• Always track your screws to avoid putting back in the wrong place and damaging your device. You can draw a picture of your laptop and tape the screws to the right places or use a screw mat
• The bottom case is held by eight P5 pentalobe screws (four 9.1 mm and four 5-6 mm) plus hidden clips. Lift the front edge with a suction cup, slide a pick around the sides to release the clips, then pull the case toward the front to free the sliding clips at the back
• Before any component removal, peel the tape off the battery data cable, flip up the ZIF lock and slide the cable out. Then remove the 3.9 mm T5 pancake screw and lift the battery connector clear of its socket
• Remove the trackpad cable bracket (two 2.1 mm screws) and disconnect the trackpad. The trackpad has to come out (T5 screws of two lengths, 5 mm and 5.8 mm, so keep them apart)
• Remove the two T5 screws holding the battery board
• Pull each stretch-release strip slowly, low and flat. If one snaps, add a few drops of isopropyl alcohol under the cell, wait a minute or two, and lift with a plastic card. Keep the alcohol away from the speakers
• Never pry against a cell with metal tools, and never bend, squeeze or puncture the cells when removing the old battery or fitting the new one
• The new adhesive strips come in the box. Fit them to the new battery, press each cell down, and refit the trackpad screws loosely before tightening so it lines up
• If your newly installed battery is draining fast or shutting off randomly, first try the battery calibration steps found here. Apple silicon Macs have no SMC reset - shut down, wait 30 seconds and restart
