Insert your plastic card under the short edge of the lower battery cell to slice the adhesive.

Don't puncture or bend the battery. If it feels stuck, apply a few more drops of isopropyl alcohol or apply a heated iOpener to the back of the frame.

Insert the plastic card again under the long edge of the lower battery cell to slice the remaining adhesive.

Twist your plastic card to lift the short edge of the battery cell from the frame.

Don't try to remove the battery yet—it's still connected to the battery board.
