A galvanic cell produces lower voltage than the earlier electrostatic generators, but the miraculous thing is that the electricity is produced merely by combining two different metals and a substance through which the metals connect.

During this era, the scientific community referred to the electric battery as a ‘pile’ or an ‘accumulator’, as well as an ‘artificial electrical organ’. All batteries use a direct current system where electrons flow in only one direction.

As times have advanced, we’ve seen batteries that last longer, have more voltage and even the advent of consumer rechargeable batteries for everything from watches to digital cameras.
