I've have a old video of one of my attempts at making the same metal water battery into a real battery by putting many cells together. You'll notice I call the same metal water battery a water captret, it was because at the time i was dealing with the captret idea and it seem to act like the captret. I've come to know now that the captret and the this same metal water battery are not really the same, but they do share a lot of similarities. In this video below I show that the battery outputs more power over time when given a load. This is something that normal batteries or even normal water batteries can't do, thus showing that my cells are doing something special.
