Use an opening pick to pry up the battery from the bottom using firm, constant pressure.

Do not use excessive force or pry at the battery with metal tools.

You will be prying against the case directly above the daughterboard and antenna cables. Pry carefully to avoid damaging either of these components.

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.

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.
