Avoid prying near the battery while removing the shields—a punctured or bent battery may leak dangerous chemicals or cause a thermal event.

Note that the shields may fling off of the frame when you detach them. You can place a finger on the shield to prevent it from flinging.

Insert one tine of a pair of pointed tweezers under a corner of the square shield.

Lift up the corner to detach it from the frame.

Continue to pry up additional areas around the edges of the shield until it detaches from the frame.

Remove the square shield.

If you are going to reuse these shields, try to avoid excessively bending them during removal.
