IEC/EN 62133 Certification

IEC 62133 / EN 62133 is the standard for safety requirements of portable sealed secondary battery cells and battery packs containing alkaline or other non-acid electrolytes, developed by the International Electrotechnical Commission (IEC) and the European Committee for Electrotechnical Standardization (CENELEC). The full title of IEC 62133 is "Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications." This standard is one of the most authoritative international standards in the field of battery safety, widely adopted or adapted by major global markets including the EU, USA, Japan, and Korea. The latest versions are IEC 62133-2:2017+AMD1:2021 (for lithium-ion batteries) and IEC 62133-1:2017 (for nickel-based batteries). The older IEC 62133:2012 has been gradually replaced.

IEC/EN 62133 certification is applicable to the following product types: sealed secondary battery cells and battery packs for portable applications, including lithium-ion batteries (including lithium polymer batteries) and nickel-based batteries (Ni Cd, Ni MH). Typical applications include but are not limited to: rechargeable batteries in mobile phones, laptops, tablets, digital cameras, camcorders, Bluetooth devices, portable navigation devices, power tools, portable medical devices, and children's toys. The standard does not apply to electric vehicle power batteries, stationary energy storage systems, or industrial large-scale battery systems. The new IEC 62133-2:2017 further clarifies the definition of portable batteries and defines rated energy limits.

IEC 62133 is one of the core standards of the CB Scheme (IECEE CB Scheme), enabling multi-national mutual recognition. Under the CB Scheme, companies can submit an application to any National Certification Body (NCB) and, after obtaining a CB Test Certificate (CBTC), apply for conversion certification in CB Scheme member countries, avoiding duplicate testing. Currently, more than 50 countries and regions participate in the CB Scheme, including China, the USA, Japan, Korea, Germany, France, and the UK. Through IEC 62133 CB certification, companies can efficiently obtain market access qualifications for multiple target markets, significantly reducing certification costs and time.
