In fact, many archaeologists now believe that the Baghdad Battery had no electrical purpose at all. The usability of the ancient batteries has been proven in various scientific and entertainment arenas, but so far all that can be said is that it was possible to produce electricity with these primitive cells. Whether they were ever used for that purpose – and what, exactly, they may have powered – may never be known. Like the Antikythera Mechanism and so many other ancient gadgets, its function may be forever lost to time.
