Batteries are energy storage devices that power consumer electronics and other machines. They come in many shapes, sizes, and capacities.

About Batteries

In electricity, a battery is a device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy. Since the invention of the first battery (or 'voltaic pile') in 1800 by Alessandro Volta and especially since the technically improved Daniell cell in 1836, batteries have become a common power source for many household and industrial applications.
