I’m planning a long article about the baghdad battery. But first things first: let me see it working! I don’t care “expert opinion”, facts are facts. So I set up this “baghdad battery” in a rush, as a proof of concept, and TÁDÁMMM! it works. Even this rudimentary setup... show more

There is much older battery as well, mentioned by Sage Agastya in his book Agastya Samhita, his timelines are considered to be 2000 BC. Here is working experiment done by Praveen mohan.

How about trying with natron for an alkaline battery?

Natron? Hmmm

10-15 of these. Not that hard!

Standard of science fairs since at least 1966 in the US...

Did you use fresh squeezed organic orange juice or orange juice from either/and concentrate, has added sugar, grown with pesticides? Just wondering if any of those additives or changes to the orange juice would make a difference in the voltage it produces…

No, the voltage only depends on the two metals. In fact, you can pre-calculate the achievable voltage up front, without any knowledge of the liquid by using the standard elecric potential table. Copper: -0.34, Iron: +0.45, the distance is 0.79 V, the theoretical maximum with these 2 metals. The electrolit can be anything that can ship ions from one to the other. An acidic liquid is good, but salty water (a soup for example) would do the trick as well. This juice is from concentrate. But it doesn’t matter. It’s acidic, that’s the key.

I wonder what did they power with it.

Try lemon juice to see if there is any voltage difference.
