A mercury battery (also called mercuric oxide battery, or mercury cell) is a non-rechargeable electrochemical battery, a primary cell.
Mercury batteries were used in the shape of button cells for watches, hearing aids, and calculators, and in larger forms for other applications.
Due to the content of mercury, and the resulting environmental concerns, the sale of mercury batteries is banned in many countries. Both ANSI and IEC have withdrawn standards for mercury batteries.
