1. CR2032 and CR1632 batteries are named according to IEC standards. Among them, C-indicates the chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode, R-indicates that the shape of the battery is cylindrical, and if it is square, replace it with F; 20 indicates that the diameter of the battery is 20mm, and 32 indicates the diameter of the battery The height is 3.2mm.

2. The nominal voltage of CR2032 and CR1632 batteries is 3.0V, and the working current and rated capacity vary with the manufacturers. With the requirements of the new industry, there are also specially improved batteries with very different capacities, mainly to improve their high-current output capabilities, such as those used in flashlights or RF products.

3. The battery is often used in CMOS batteries of computer motherboards, other memory functions or power-off protection modules, electronic scales, calculators, electronic dictionaries and other products.
