Founding

In 2007, a team of professionals with over 20 years of experience in the lead-acid battery field joined forces to start a new company that would focus on automating the battery manufacturing process. Yuan Charm Enterprises Co. Ltd. was thus established, with its factory and HQ in Taichung, Taiwan's industrial center and second largest city.
