What is the UL 4200A Warning Label?

Products exported to the United States that contain button cell batteries, such as quartz watches, locators, music boxes, etc., are required to have a UL 4200a warning label. This is to prevent button batteries from falling out and being swallowed by children, which could pose a life-threatening risk. Below are the requirements for the UL 4200A warning label. If you need assistance, you can directly contact JJR Laboratory in China.
