Repeat the procedure from the prior steps to separate the two battery cells on this side:

Apply your adhesive remover to the elevated edge of the outer left battery cell, and wait 2-3 minutes for it to penetrate.

Work one corner of a plastic card underneath the battery cell, and slide the card fully underneath the battery cell to separate it.

Do the same for the adjacent cell.

Leave your plastic card in place or flip the battery cells over to prevent them from re-adhering during the following steps.
