Allow your MacBook's battery to drain below 25% before starting this repair—a charged battery may catch fire if damaged.
Unplug all cables and fully power off your MacBook.
Close the display and lay your MacBook upside down. Keep your laptop closed until you've physically disconnected the battery.

Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.
Use a P5 pentalobe screwdriver to remove the four 6.4 mm‑long screws securing the lower case.

Apply a suction handle to the center of the lower case's front edge.
Pull up on the suction handle to create a gap between the lower case and the frame.
Insert an opening pick into the gap.

During the next two steps you'll feel and hear six snapping clips release. If a clip doesn't release, insert your opening pick farther and try again.
Slide the pick to the bottom right corner to release the first clip.
Slide the pick around the corner and up the right edge to release the next two clips.

Insert the opening pick in the original gap created with the suction handle.
Slide the opening pick to the bottom left corner and up the left edge to release the three remaining snapping clips.

Four sliding tabs along the back edge of the MacBook firmly secure the lower case. Separating these tabs requires a lot of force—consider using gloves to protect your hands from the sharp edges of the lower case.
Keep the lower case flat to the frame and firmly slide it straight away from the back edge, one corner at a time, to disengage the sliding tabs.
Don't pull up until the cover is completely separated.

Remove the lower case.
During reassembly:
Set the lower case in place and align the sliding tabs with the screw heads they slide over. Press down and slide the lower case toward the back edge to engage the tabs—it'll stop sliding as the tabs engage.
When one side is engaged, it may push the other out of alignment. Check both sides as you push, there should be no gap along the back edge.
Once the lower case is flush with the frame, press down firmly along the perimeter to engage the six snapping clips.
You'll hear and feel a distinct click as each clip snaps into place.

Tweezers

$4.99

Use blunt nose tweezers or your fingers to remove the piece of tape covering the battery connector cover.
During reassembly, use the leftover adhesive to secure the tape to the cover.

Use a 3IP Torx Plus screwdriver to remove the two 1.5 mm‑long screws securing the battery connector cover.
Remove the cover.

Use an opening pick to pry up and disconnect the battery connector.
To reconnect a press connector, align it over the socket and gently press down on one side until it clicks into place, then press down on the other side. It might take a few tries to align the connector.
