Battery (electricity)

In science and technology, a battery is a device that stores chemical energy and makes it available in an electrical form.

It consists of one or more voltaic cells, each of which is composed of two half cells connected in series by the conductive electrolyte.

Even if never taken out of the original package, disposable (or "primary") batteries can lose two to twenty-five percent of their original charge every year.
