Battery (electricity)

In science and technology, a battery is a device that stores chemical energy and makes it available in an electrical form. Batteries consist of electrochemical devices such as one or more galvanic cells, fuel cells or flow cells. Strictly, an electrical "battery" is an interconnected array of similar cells, but the term "battery" is also commonly applied to a single cell that is used on its
