In 1938, an Austrian archaeologist Wilhelm Konig made an astonishing discovery while rummaging through the basement of a museum in Baghdad. A small pot of bright yellow clay dating back from more than two thousand years ago containing a cylinder of copper. The edge of the cylinder was soldered they things are soldered nowadays.
The iron rod that was suspended into the center of the copper cylinder showed evidence of corrosion. According to Konig, the clay pot was nothing less but an ancient electric battery.
It dates back from the Parthian occupation between 248 BC and 226 CE. Nevertheless, Konig also found copper vases plated with silver in the Baghdad Museum that dates back the at least 25000 BC.
According to many theories, the Parthians inherited this kind of technology from a much older civilization. At the same time, similar batteries like this one can be placed in ancient Egypt since there are many anomalous findings from other regions that suggest the use of electricity by many ancient civilizations.
There is no need to say that the ones found in Baghdad are not too powerful since it is needed a substantial dynamo-generated current.
