CR2032 button cell battery is a Li-MnO2 battery, which belongs to lithium-manganese dioxide structure, the positive electrode material is manganese dioxide with very stable chemical properties, and the negative electrode material is graphite with high conductivity. Li-MnO2 battery has the characteristic feature of long service life, low self-discharge, and good reliability. It can be applied in various fields such as electric clocks, watches, and hearing aids.


CR2032 button cell battery, where 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; 20 indicates that the diameter of the battery is 20mm, and 32 indicates that the height of the battery is 3.2mm. The nominal voltage is 3.0V, and the rated capacity is 225mAh, depending on the level of the manufacturer. With the requirements of the new industry, there are also especially improved batteries with very different capacities, mainly to improve their high-current output capabilities, such as those used in flashlights or RF products.

How to extend the lifespan of CR2032 button cell batteries?

There are a few things that can be done to help extend the lifespan of CR2032 button cell batteries:

  1. Store them in a cool, dry place: Batteries last longest when stored at room temperature in a dry environment. Avoid storing batteries in direct sunlight or humid locations such as bathrooms.
  2. Follow manufacturer’s instructions: When installing new batteries, be sure to follow the manufacturer’s instructions carefully. This will help ensure that the battery is installed correctly and makes good contact with the device’s terminals. Improper installation can lead to reduced battery life or even damage to the device.


CR2032 button cell batteries are an excellent choice for small electronics such as watches, calculators, and remote controls. Taking simple steps to extend the life of your CR2032 batteries will allow you to get more out of them.
