Button cell, also known as button cell, refers to the battery whose overall dimension is like a small button. Generally speaking, the diameter is large and the thickness is thin. The size diameter ranges from 4.8mm to 30mm and the thickness ranges from 1.0mm to 7.7mm.
The widespread use of button batteries is particularly common, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controls, electric toys, counters, cameras and so on. It is precisely because of its universality and small shape that children eat by mistake and other safety accidents, which has aroused the attention of consumers, and began to pay more and more attention to how to use button batteries more safely? International, national and regional standards have also been issued to test various measures for button batteries. Therefore, battery products that meet relevant international standards can gain the trust of more consumers.
