When "crystal" in the name is a registered trademark, that in itself makes me suspicious. I have an insecticide that is called "Golden Malrin." Of course, gold has nothing to do with it.
I wonder whether the actual battery may be a glass, rather than a crystal? Anyway, I don't consider some free-energy "researcher" much of an authority on anything except selling stuff to the gullible.
EDIT:
Maybe before we get too deeply into discussion of our own interpretations of what a "crystal battery" would be, shob77 should define what he means by that term. And if possible, he should specify what materials are used for the electrodes.
