• 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 2012-2013 models have no Auto Boot, so no Terminal commands are needed. Just shut down fully and unplug the charger
• The P5 pentalobe 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 ten P5 pentalobe screws (eight 3.0 mm and two 2.3 mm). Lift it off from the hinge edge
• Before attempting any component removal, peel back the warning label and lever the battery connector straight up with a spudger, then bend the cable away from the board. Use the replacement connector cover tape on reassembly
• This is a full teardown: the fans, AirPort card, SSD, I/O board, logic board and both speakers come out before the battery. Slide the camera and display data cables out parallel to the board, don't lift them
• Before lifting the logic board, check no cables are still connected or trapped (keyboard, trackpad, battery, speakers, backlight, display, mic)
• Remove the two T5 screws holding the battery control board
• The six cells are glued to the top case. Cover the display with foil, prop the MacBook on its side, then work cell by cell: a few drops of adhesive remover or isopropyl alcohol, wait two to three minutes, and slide a plastic card under. Leave the cards in so the cells don't re-stick
• 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. Leave the thin metal plate over the trackpad in place
• Clean off all the old adhesive and let the case dry. Test-fit the new battery before peeling the liners, then press each cell down firmly
• 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
