What not to have in the dry box

I got my Nikon only 2 weeks back. I also got a 'free' dry box (not the sophisticated one, simple one). I was just wondering what and what should and should not be kept in the dry box with the camera and lenses.

At the moment, I have the charger, Nikon remote controller and extra battery also in the dry box. May be they are perfectly safe to have inside it together with the camera and lenses. But i'd like to hear the expert advice. Please help...

It depends why you need to keep all the kit in there at the same time, but going off the info given thus far, I would say there's no reason why you can't keep all the kit in there at the same time

Obviously cover your battery terminals so they don't short out with anything they might come in contact with etc

For sure you can have the battery and charger in the dry box together with the body and lens. I do not see any issue with that. But don't keep your camera in there for too long - it is meant to be out there taking pictures.
