The more common button cell batteries include AG3, AG10, AG13 used in toys and gifts, CR2032 batteries on computer motherboards, CR2025 used in electronic dictionaries, CR2016 or SR44, SR626 used in electronic watches, etc.;

The button battery case 2016 2025 2032 made of #304 stainless steel is composed of a positive electrode case, a sealing ring and a negative electrode case. The sealing ring is injected on the negative electrode case and is mainly used for the production of button battery and testing and research on the performance of lithium battery materials；

Components such as gaskets, positive and negative electrode shells must be repeatedly cleaned ultrasonically with alcohol before use, and then dried in a forced air drying oven.
