How long is the life of the button battery CR2032 on the computer motherboard?

CR2032 is used to store the time and startup sequence of integrated circuit system on computer motherboard according to different service life. Because the computer motherboard has an external power supply to charge the battery, it has a long service life and can be replaced in 7-10 years.

CR2032 The storage life of is usually 5 years. If the manufacturer's manufacturing level is not high or the quality control is not good, the service life will be greatly shortened. At present, domestic first-line brand batteries can basically guarantee this service life. If the service environment is ideal (sealed, normal temperature, no interference, etc.), the service life will be further extended, up to 8 years or even 10 years.

CR2032 lithium manganese battery, named according to IEC standard. In the formula, C - represents the chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode, R - represents the shape of the battery is cylindrical, if it is square, replace f; 20 means the diameter of the battery is 20mm, and 32 means the height of the battery is 3.2mm. The nominal voltage is 3.0V, the terminal voltage is 2.0V, and the rated capacity is 200-240mah, which varies according to the manufacturer's level. With the requirements of new industries, there are also specially improved batteries. Their capacities will vary greatly, mainly to improve their high current output capacity, such as those used in flash lamps or RF products.

CR2032 battery is commonly used for CMOS battery of computer motherboard, other storage functions or power-off protection modules, electronic scales, calculators, electronic dictionaries and other products.
