Development of the Modern Battery

I found this clip explaining a theory on Egyptian batteries and the possibility that they powered light bulbs. Ignore the alien stuff at the end because I really don't think it's relevant to the main idea. Very interesting stuff!

The accepted battery timeline shows Voltaic pile as the first battery able to provide a current to a circuit continuously. It looked something like this...

This was followed by the Daniell Cell, which improved upon the Voltaic pile by using different metals.

Bunsen created the first liquid battery in 1842.

Leclanche created the first dry cell and therefore portable battery in 1866...

Carl Gassner invented the first first commercial battery in 1881 and the rest is history...
