CR2032 button cell batteries

Button battery models can be classified from single standards such as structure, voltage, size, etc., and composite button batteries can also be classified. Practical button lithium batteries are generally marked from two aspects of structure and size.

Button batteries can be divided into two types: rechargeable and non-rechargeable. Common rechargeable button batteries include 3.6V LIR series, 3V ML series, and LV series. Non-rechargeable button batteries include 3V CR series, 1.5V LR series, and 1.55V SR series.

The button battery model is composed of English letters and numbers. The first English letters indicate the nature of the chemical power source, and the suffixed four Arabic numerals indicate the battery size. The first two numbers indicate the diameter, and the last two numbers indicate the thickness.

Button batteries are small in size and are generally used as backup power for electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, calculators, etc., with diameters ranging from 4.8mm to 30mm and thicknesses ranging from 1.0mm to 7.7mm.
