I've done purely and noticed that it is a little too big Ansmann batteries. This manifests itself in the fact that I have to turn the box with a little more force, so that it jumps up. Actually, a slight press on to the inside at the closer is necessary to open, so it does not go with the big toys. 1mm more radial game could be enough. I keep the same. For batteries it fits perfectly. The boxes can be mounted side chains. To be listed in the little closet. I like.
