Excerpt: In science and technology, a battery is a device that stores energy and makes it available in an electrical form. Batteries consist of electrochemical devices such as one or more galvanic cells (or, more recently, fuel cells). The earliest known artefacts that may have been batteries are the Baghdad Batteries, from some time between 250 BCE and 640 CE. The modern development of batteries started with the Voltaic pile developed by the Italian physicist Alessandro Volta in 1800. Strictly, an electrical "battery" is an interconnected array of one or more similar "cells." That distinction, however, is considered pedantic in most contexts (other than the expression dry cell), and in current English usage it is more common to call a single cell used on its own a battery than a cell. For example, a hand lamp (flashlight) (torch) is said to take one or more "batteries" even though they may be D cells. A car battery is a true "battery" because it uses multiple cells. Multiple batteries or cells may also be refered to as a battery pack, such as a set of multi-cell 12 V batteries in an electric vehicle. Circuit symbol for a battery; simplified electrical model; and more complex but still incomp...
