Watch, “coin-size,” AAAA, AAA, AA, C, and D sized single electrochemical cells are marketed and sold as “batteries.”

The cell’s voltage and amperage are dependent upon chemistry of its electrodes and electrolyte (including surface area, chemical purity, and volume) as well as its storage and operation conditions.

Technically a battery is made from multiple cells connected in series or parallel. A twelve volt automobile battery and a nine-volt battery are examples of batteries comprised from multiple single cells.
