Here's my (free) solution for keeping spare NP-95 (and equivalent batteries) from colliding and igniting! Use empty tictac containers. Just cut open the foil label and hack back the plug top to just under the 'snap' bump. To access, flip open the small 'door' and pull to remove the whole top plug. Secure and smells minty. Cat for scale only.
