CR2025 battery

Several common button battery models:

1. CR button battery model: commonly used are CR2016, CR2032, CR2025, where CR means lithium manganese dioxide battery, and the last four digits indicate the size, for example, CR2032 refers to a 3V button with a diameter of 20mm and a height of 3.2mm Battery.

2. AG series button battery model: The AG battery commonly called in China is essentially an alkaline zinc-manganese battery. There are 14 product series from AG0 to AG33. However, in the IEC standard, the labeling method for alkaline batteries is still followed by " LR" letters for identification, where L stands for alkaline and R stands for round.

3. Zinc-silver oxide battery: The size of silver oxide battery can be made into the same size as alkaline zinc-manganese button battery, but the voltage platform of zinc-silver oxide battery is relatively higher, and the working voltage is more stable. Its naming method is similar to that of LR The series are basically the same, such as "SR44" means zinc-silver oxide battery, which is both the size of LR44 and the size of AG33.
