What does having IEC62619 mean? But no CEC certificate
IEC 62619 is an international safety and performance standard for secondary (rechargeable) lithium-ion batteries used in industrial and stationary applications. Meeting IEC 62619 ensures that the cells and battery packs have been tested against hazards such as overcharge, short-circuit, thermal extremes and mechanical abuse, giving confidence in their safe operation in demanding environments
