• 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 bottom case comes off or a charger is connected. Before you start, turn off AutoBoot in Terminal with sudo nvram AutoBoot=%00, then power down. Turn it back on afterwards with sudo nvram AutoBoot=%03
• The P5 pentalobe, T3, T5 and T8 Torx screwdrivers you need are included in the box
• 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 six P5 pentalobe screws (four 3.7 mm, two 7.3 mm, fitted at an angle) and hidden clips. Lift the front edge with a suction cup, release the side clips with a pick, then slide the case towards the front rather than lifting it up. On reassembly, hook the hinge-side clips first
• Disconnect the battery first: peel the control board sticker and data cable tape, flip up both ZIF flaps, slide the cable out, then remove the T5 screw on the power connector and lift it. A damaged cable or unlatched ZIF is the most common reason a new battery isn't recognised
• The trackpad has to come out (13 T5 screws). Its cable is glued to the battery, so warm it gently and peel it off slowly. Keep the nine small washers from the screw posts
• The logic board also has to come out (mixed T3, T5 and T8 screws). The keyboard ZIF flap is long and fragile, and the Touch ID and headphone connectors can catch under the board on reassembly
• Remove the T5 screw holding the battery control board
• The cells are glued to the top case. Cover the display with foil, tape over the trackpad opening and prop the hinge end up, then work in pairs (right, left, centre): a few drops of adhesive remover or isopropyl alcohol, wait about two minutes, and slide a plastic card under
• 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
• Clean off all the old adhesive, test-fit the new battery and press each cell down. Make sure the trackpad cable isn't trapped under the battery
• If your newly installed battery is draining fast or shutting off randomly, first try the battery calibration steps found here. If that doesn't resolve it, try an SMC reset
