How long would this kind of battery last before unrecoverable failure? From what I can tell, this is essentially a potato battery where the paper is the potato and the penny and nail are printed on the paper. Eventually the printed zinc and graphite terminals are going to corrode completely (well maybe not so much the graphite). Once all the zinc is oxidized, that's it.

It isn't intended to be recharged.
