CR2032: lithium manganese dioxide battery is named according to IEC standard. Where C - is the chemical battery system with lithium metal as negative electrode and manganese dioxide as positive electrode, R - is the cylindrical shape of the battery, if it is square, then f is substituted; 20 is the diameter of the battery is 20 mm, 32 is the height of the battery is 3.2 mm. The nominal voltage is 3.0V, the end point voltage is 2.0V, and the rated capacity is 200-240mah, which varies with the level of manufacturers. With the requirements of the new industry, there are also special improved batteries, whose capacity will be very different, mainly to improve their high current output capacity, such as for flash lamp or RF products.
The battery is commonly used in computer motherboard CMOS battery, other memory functions or power-off protection module, electronic scales, calculators, electronic dictionaries and other products. It can also be used in car remote control key.
