Actually, early "batteries" discovered in the 1960s that were found in the the region of modern Bagdad, middle-east, have been dated to about 250 BC!
And no one has yet figured out what they were used for. They remain in a museum in Berlin, Germany. Clay pots surrounding a rolled copper cylinder, with an iron rod through the center, and a lid to hold in whatever acidic liquid (sea water; lemon juice?) was placed inside. They actually generate electron flow.
History is lots of fun!!
And humans have been smarter than we suspect, for far longer than we know.

Too bad they never found the light bulb that went with it!
That would mess up the Edison fans!
(That's the one that looked more akin to a hand grenade than a battery is it not?)
I was thinking on the lines of commercially sold batteries. If I remember right, invented in the late 1700's, and became available in the early 1800's.
