Answer: 1 is an array of Leyden jars which look like a “Battey of cannons”. Thus Benjamin Franklin called 1 as “Battery”. The name is used even today.

    1) A “battery” of Leyden Jars derived from a “battery of cannons”

    2) Benjamin Franklin

    Directly quoting from Wikipedia

    The name “battery” was coined by Benjamin Franklin for an arrangement of multiple Leyden jars (an early type of capacitor) after a battery of cannons. Common usage has evolved to include a single electrical cell in the definition.
