    The Road to Safety Compliance for coin batteries: An overview of UL 4200A standards

    Author:中認聯(lián)科 time:2025-02-11 Ctr:1221

    In the field of consumer electronics and medical devices, button or coin batteries are widely used due to their small size, portability, and high energy density. However, the safety performance and quality control of these batteries have been the focus of manufacturers.

    Meaning of UL 4200A certification

    The UL 4200A certification is a standard developed by Underwriter Laboratories (UL), a world-renowned third-party safety certification body, specifically for evaluating and certifying the safety performance of low-voltage DC power supplies, including button and coin batteries. The standard not only requires the safety of the battery under normal conditions of use, but also covers the performance and durability of the battery under abnormal conditions. With UL 4200A certification, manufacturers can demonstrate to the market the reliability and safety of their products, thereby enhancing customer trust and expanding market share.
