Carefully insert a plastic card under the bottom right corner of the battery.

Slowly slide the plastic card across the bottom edge of the battery to make a gap for the liquid adhesive remover.

At this point, you do not need to push the card very deep under the battery. 0.5 inches (13 mm) is more than sufficient.

While some bending of the battery pack will be inevitable, try not to form any sharp creases, which will compromise the battery structure and potentially trigger a fire hazard.
