Lift the battery and pull it towards the bottom of your laptop so the battery cable slides out from under the logic board.

Remove the battery.

Remove any remaining adhesive from the frame and clean up the residue with a few drops of isopropyl alcohol and a microfiber cloth.

Before removing any adhesive liners, place the battery in its recess and make sure it fits.

If your replacement battery comes with adhesive, remove the plastic liners and firmly press each cell into place.

If your replacement battery doesn't come with adhesive, secure it with stretch-release adhesive or double-sided tape.
