Insert the long edge of an opening pick between the battery and its housing at the side opposite the battery cable.

Push the opening pick under the battery and lift up to pry the battery out of its housing.

Make sure you push underneath the battery and not into it. Don't bend, crease, deform, poke, or puncture the battery—a damaged battery is a potential fire hazard.

If you encounter significant resistance, pause and reheat the adhesive.
