Once the battery has slightly lifted, insert a second opening pick at the bottom left corner.

Slide the opening pick along the edge to the left center and slide it under the battery.

In case you're having trouble to cut the adhesive, reapply the iOpener for another minute to loosen it.

Insert a third opening in the center of the right edge and slide it under the battery to cut the remaining adhesive.

Make sure not to damage the interconnect cable that runs on the right side underneath the battery.
