Coin button batteries look like a button, hence the name. Their small circular size ranges from 5 to 25 millimetres in diameter, and 1 to 6 millimeters in height, and they’re single cell, which means they are single-use and disposable.  




There are three main materials used in coin button batteries: alkaline, lithium and silver oxide. A metal can forms the bottom body and positive terminal of the cell, while an insulated top cap forms the negative terminal.
