Mercury-free and environment friendly

In 1980, ChungPak was founded in Hong Kong. The company’s main focus was button cell production, with watch manufacturers as its target customers.　Since 2004, Vinnic developed superior Primary Button Cell by using first-rank material. While the safety standard of heavy metal for mercury is 5 ppm, lead is 40 ppm and cadmium is 20 ppm, the relevant contents in Vinnic's Primary Button Cell are much lower than the standard. This is a further milestone in the development of high performance, reliable and environment friendly batteries.
