As you slice through the adhesive with the opening pick, try your best not to bend the battery pack. Soft shell lithium-ion batteries are highly susceptible to damage and can ignite when compromised.

Insert another opening pick into the right edge, near the first opening pick.

Slide the opening pick down along the right edge to loosen the right adhesive strip.

If the slicing feels difficult, apply a few more drops of isopropyl alcohol into the edge, wait a minute for it to seep in, and try again.
