CR1632: Lithium manganese dioxide battery, which is named according to the IEC standard. C- indicates a chemical battery system with lithium metal as a negative electrode and manganese dioxide as a positive electrode, R- indicates that the shape of the battery is cylindrical, and F is replaced if it is square; 16 indicates that the diameter of the battery is 16mm, and 32 indicates that the height of the battery is 3.2mm. The nominal voltage is 3.0V, the end point voltage is 2.0V, and the rated capacity is 120mAh, which varies according to the manufacturer level. With the requirements of the new industry, there are also special improved batteries, whose capacity will be very different, mainly to improve its high current output capacity, such as applied to flash lights or RF products.

The battery is often used in computer motherboard CMOS batteries, other memory functions or power failure protection modules, electronic scales, calculators, electronic dictionaries and other products.

The storage period of CR1632 is usually 5 years or more, if the manufacturer's manufacturing level is not high, or the quality control is not good, its life will be greatly shortened. The batteries of Liyuan Battery Technology can basically guarantee this period. If the use environment is very ideal (sealed, normal temperature, no moisture and other interference), the storage life of the lithium metal battery will be further extended, up to 8 to 10 years.
