Button, coin, or watch cells. A button cell, watch battery, or coin battery is a small battery made of a single electrochemical cell and shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high – resembling a button.
Also called CR1/3N because it is 1 ⁄ 3 rd the height of an alkaline N cell, and a stack of three of them will form a battery with the same dimensions as an N cell, but with 9 V terminal voltage. Such 9 V batteries in a single package do exist but are rare and only usually found in specialist applications; they can be referred to as 3CR1/3N.
Mercury battery "РЦ-53М"(RTs-53M), Russian manufactured in 1989.
