Use this guide to remove and replace the glued-in battery from your 12-inch MacBook with Retina Display. This is best done with the help of an iFixit battery replacement kit; the liquid adhesive remover in your kit will dissolve the adhesive securing the battery, allowing you to remove it with ease.
iFixit adhesive remover is flammable. Perform this procedure in a well-ventilated area. Do not smoke or work near an open flame during this procedure.
For your safety, drain your MacBook's battery before you begin this procedure. A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured.
The MacBook's battery contacts are located under the logic board, and this guide recommends removing the logic board completely for battery replacement. While it's possible to remove the logic board screws and simply tip the board up slightly to remove the battery, it's very difficult to install a new battery correctly with the logic board still in place.
Note: The solvent used to dissolve the battery adhesive can damage and/or discolor certain plastics. Take care where you apply the solvent.
To avoid logic board damage, when your MacBook repair is complete but before powering it on, connect it to low-voltage power using a 5-Watt iPhone charger and a USB-C to USB-A cable. These accessories are not included with your MacBook, so make sure you have them ready before you begin.

Beautiful. ‘Followed the instructions to a T. No issues at all. Thanks!
Everything worked, except the keyboard. No backlight, no power. Using remote keyboard for now. Any ideas? Trackpad works fine.
@nabrams1 Check both cables that connect to the trackpad—make sure all four connectors are clean and fully seated, and that the cables aren’t damaged in any way. The first cable connects the keyboard to the trackpad, and should not have been disconnected, but check it anyway. The second cable connects both keyboard + trackpad to the logic board. Good luck!
I did try all of those and checked the cables and ZIF connectors under a microscope. I am thinking a bad trackpad now since it works fine, but the keyboard does not respond. The only way I have figured out o use the machine is to disconnect and reconnect the battery, which is not easy. Otherwise, I cannot power it on myself since the power button is part of the keyboard. Apple won’t touch this now since I replaced the battery myself, so it is kind of a brick. I can’t run AHT since the keyboard doesn’t respond (command-D). Any ideas?
Bad trackpad seems possible. If the keyboard was working before the repair, there may be damage to the trackpad or the logic board itself. It’s hard to say without swapping out parts to test, unless you have a microscope + multimeter + board schematic, and we’re rapidly getting out of DIY territory there. I’d probably take another look at the cables and sockets just to make extra sure it’s not something simple. Hope this helps!
