Carefully pull the battery connector away from the battery to disconnect it from the motherboard. You may find it helpful to insert an iFixit Opening Tool to gently separate the connector from the housing.

Pull parallel to the motherboard, not straight up, or you will damage the socket.

Use a Phillips screwdriver to remove the eight screws securing the battery.

Release the tape underneath the U-shaped hard ribbon connector. There is no need to remove the U-shaped band completely, gently lift the section overhanging the battery and pull back the corners of the tape from the top of the battery upwards. You can use long/fine tweezers to lift the tape completely free of the battery, working from each end.

Lift the battery off the palm-rest assembly.
