Baghdad Battery or Parthian Battery are the terms used to refer the artifacts that were created long ago in the early years AD. However, these relics were discovered after many centuries in 1936 in Baghdad. Each of these jars were as tall as 5 inches. Due to its archeological importance, these artifacts were placed in Baghdad museum.

What is Baghdad BatteryTwo years later, Wilhelm Konig, a German archeologist, visited the museum to witness the masterpiece. However, he noticed something that rest failed to observe. These jars were not anything else but batteries that were used during the third century AD. Inside the jar, there was a tall iron rod, insulated by copper. These metal rods were connected to the top end with an asphalt stopper. When one fills the Parthian battery with an electrolyte like vinegar, difference in voltage takes place.

Konig later published papers on how these batteries operate and used to store electricity. As soon as the word spread, people began to build up new stories. Some mentioned that similar batteries were used by Egyptians to light electric bulbs in the pyramid. However, the people who started spreading such rumors failed to recollect that mummifying was a tradition practiced about 2,000 years ago, when even irons were not in use, let alone electric bulbs.

An engineer from General Electric, in 1948, tried to replicate the process and successful generated electricity of 2 volts. However, capacity of thie power was considerably low, about 1/40th the capacity of triple-A batteries. But a German scientist later discovered that using such batteries in more number can help Baghdad Batteryelectroplate sheets of silver and gold.

Although this artifact serves as a proof that people in ancient era made use of electricity, many archeologists fail to believe that they actually did that, and this might just be an attempt to store electricity. These archeologists have logical arguments to support their views. There are no archeological wires found, which is an important element to collect or transmit power. Besides, the bitumen covers the copper insulation completely, which makes it impossible to draw electricity without altering the design. There are no archeological electrical equipments, which might have been operated on this electricity.

The mystery of Baghdad battery is yet to be solved. Archeologists and scientists around the world are trying hard to come up with a logical answer. But attempts so far have been futile.
