What is a cell; what is a battery, and what is the difference between the two?
A cell is a device that chemically stores and produces voltage with
an electrode and electrolyte. A battery is a bank of 2 or more cells that
work in unison to generate a greater voltage or amperage depending
on the arrangement of the battery
