    That is a good question. I made this battery one night and the next day it had a much lower voltage even though it wasn't hooked up to anything overnight. There were obviously some reactions happening overnight though since the water was more green the next day. It may have "recharged" by sanding the metal pieces off but I didn't get to test it. Of course battery life also has to do with how much current you are pulling too. I'm thinking of doing a follow up video that looks at the chemistry of this battery and talks about how and why it works so I can get some ideas of what might work better.
