Carefully insert an opening pick under the bottom of the battery.

You may need to reheat and reapply the iOpener repeatedly to further soften the adhesive. The adhesive is tough and it may take a few tries to get the pick started under the battery. If the battery begins bend out of shape, apply more heat or isopropyl alcohol and pry slower.

Try your best not to deform the battery during this process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools.

Gradually push the pick further under the battery to pry up the bottom edge.

Do not insert the pick more that ~1.5 cm past the edge of the battery to avoid damaging the daughterboard and display ribbon cables.

Slide the pick all along the bottom edge to release the bottom of the battery.
