Pull on the yellow adhesive pull tab with slow steady force. Try your best to pull it as shallow of an angle (vs. straight up) as possible.

As you pull on the adhesive tab, maintain pressure on the opening pick to wedge it underneath the battery as much as possible.

If the adhesive feels stuck, you can apply a few drops of adhesive remover or high concentration isopropyl alcohol into the gap to help loosen the battery. Doing this will most likely loosen both strips at once.

Repeat the process with the second adhesive pull tab.
