Because heat is required to remove the screen and LCD, it is advisable to remove the battery entirely as well.

It is important to be very careful and use little force in this step. Too much force can damage the battery. A damaged battery can lead to an electrical fire or explosion of the battery.

Carefully and slowly work the iFixit Opening Tool down the edge of the battery pack. Angle the tool to pry it up.

When you have successfully lifted the battery pack up on one side or corner, carefully wedge the iFixit Opening Tool under the pack about 1/2" and work around the rest of the sides.

Be careful not to bend the battery pack.
