The button batteryThe model is composed of English letters and numbers. The front English letters indicate the nature of the chemical power supply. The suffix four Arabic numerals indicate the size of the battery, the first two digits indicate the diameter, and the last two digits indicate the thickness. The button battery has a small body shape and is generally used as the backup power supply for electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, calculators, etc. The diameter varies from 4.8mm to 30mm, and the thickness varies from 1.0mm to 7.7mm.

Interpretation of CR button battery parameters

CR stands for lithium manganese dioxide battery, and the last four digits stand for size. For example, CR2032 refers to a 3V button battery with a diameter of 20mm and a height of 3.2mm.

Four series of button batteries

3.0V button type lithium manganese battery (CR series), 3.6V button type lithium ion battery (LIR series), 1.5V button type alkaline manganese battery (LR/AG series), 1.55V button type zinc silver battery (SR series).
