This artifact discovered in Iraq near Baghdad in 1936, is said to be a 1800-year-old electric cell. When tested by scientist, it produced a current of up to one volts.
Spoiler for AMAZING:
The Baghdad Battery is believed to be about 2000 years old (from the Parthian period, roughly 250 BCE to CE 250). The jar was found in Khujut Rabu just outside Baghdad and is composed of a clay jar with a stopper made of asphalt. Sticking through the asphalt is an iron rod surrounded by a copper cylinder. When filled with vinegar - orany other electrolytic solution - the jar produces about 1.1 volts.
Spoiler for AMAZING:
here is no written record as to the exact function of the jar, but the best guess is that it was a type of battery. Scientists believe the batteries (if that is their correct function) were used to electroplate items such as putting a layer of one metal (gold) onto the surface of another (silver), a method still practiced in Iraq today.

Baterai atau sel listrik pertama yang diakui dunia adalah yang ditemukan pada tahun 1800 M, jarak penemuannya hingga kini tidak sampai 200 tahun.
