Apply a few drops of adhesive remover evenly under the edge of the rightmost battery cell.

You don't need to use very much. The small bottle contains more than twice the amount of solvent needed to remove all the battery cells.

Wait 2-3 minutes for the liquid adhesive remover to penetrate underneath the battery cell before you proceed to the next step.

Use more adhesive remover if needed, but do not apply more than a few drops at a time. Using too much can allow the adhesive remover to make its way to the backside of your keyboard and potentially damage it.
