Common Battery Certification Types

In this comprehensive guide, we’ll explore everything you need to know about battery certifications, their importance, and how they impact various industries and applications.

  • UL Certification: UL 1642 / UL 2054

Description:  UL certification, issued by Underwriters Laboratories, is a globally recognized safety certification organization that tests and certifies products for compliance with specific safety standards. For batteries, UL certification rigorously tests and evaluates lithium batteries to ensure compliance with safety and performance standard.

Details:  UL certification involves rigorous testing for electrical, mechanical, and fire safety, as well as compliance with specific standards such as UL 1642 and UL 2054 for lithium batteries. UL 1642 covers safety standards for lithium batteries, while UL 2054 is specific to portable battery packs. These certifications ensure that batteries meet safety and performance standards for use in various applications.

Requirements: Testing covers aspects such as electrical safety, fire resistance, chemical composition analysis, and thermal stability to ensure battery safety under normal and abusive conditions.

UL2054 is mainly for Lithium Battery Packs or Li-ion Battery Packs (Battery Pack). Applicable to products used as a power source of primary (non-rechargeable) and secondary (rechargeable) batteries. These batteries can be composed of a single electro chemical battery or two or more lithium-ion batteries connected in parallel or series through a chemical reaction that converts chemical energy into electrical energy.

UL2054 Testing Items mainly include Electrical Testing (short circuit test, overcharge test, abuse of overcharge test, over discharge test, limit power source test), Mechanical Testing (squeeze test, impact test, acceleration test, vibration test) Battery Pack Shell test, drop test, 250N static test, mold pressure release test, fire test, projectile test, environmental test, high temperature test, temperature cycling test and so on.

Target Markets: Global

  • CB (Certification Body)

Description:  The CB Scheme is an international system for the mutual acceptance of product safety test results among participating certification organizations.

Requirements: Certification based on IEC standards, allowing manufacturers to obtain multiple national certifications using a single test report.

Target Markets: Global.

Battery Application Examples: Lithium batteries and battery-powered products seeking international market access.

  • CE Marking

Description: The CE marking indicates compliance with EU directives regarding safety, health, and environmental protection for products sold within the European Economic Area (EEA).

Details: CE marking indicates that lithium batteries comply with European Union (EU) directives regarding health, safety, and environmental protection.

Requirements: Compliance with relevant EU directives, including the Low Voltage Directive (LVD), ElectroMagnetic Compatibility (EMC) and the Restriction of Hazardous Substances (RoHS) Directive.

Target Markets: European Union and EEA countries.

  • IEC Battery Certification:  IEC 62133

Description:  International Electrotechnical Commission (IEC), is an international standards organization that develops and publishes standards for electrical, electronic, and related technologies, including safety standards for batteries.

Details: Compliance with specific IEC standards such as IEC 62133, is an international safety standard specifically for lithium batteries used in portable applications, ensuring their safety and reliability.

Requirements:  Testing for mechanical, electrical, and environmental safety under different conditions, including overcharge, short-circuit, mechanical shock, vibration, temperature extremes, and impact.

Target Markets: Global

  • UKCA (UK Conformity Assessed)

Description: UKCA marking is a UK product marking used for goods placed on the market in Great Britain (England, Scotland, and Wales) after Brexit, indicating compliance with applicable UK regulations.

Requirements:  Compliance with UK regulations, including safety standards for batteries and electrical equipment, replacing the CE marking in Great Britain.

Target Markets: Great Britain (UK), including England, Scotland, and Wales.

  • RoHS Compliance

Description:  Restriction of Hazardous Substances (RoHS), the RoHs Directive restricts the use of certain hazardous materials, including lead, mercury, and certain flame retardants, in electrical and electronic equipment.

Requirements:  Compliance with maximum concentration limits for restricted substances in batteries and battery-powered products sold within the EU and EEA countries.

Target Markets: European Union and EEA countries..

  • MSDS

Description:  Material Safety Data Sheet (MSDS), also known as Safety Data Sheets (SDS) in some regions, are comprehensive documents that provides detailed information about the properties, and potential hazards of a substance, including safety precautions for handling, emergency procedures, health hazards, and proper storage and disposal methods related to lithium batteries. It’s a standard and necessary documents for the shipment of lithium-ion batteries.

Requirements:  Preparation and provision of MSDS containing information on battery composition, hazards, safe handling, and disposal.

Target Markets: Global, providing essential safety information to users, handlers, and emergency responders.

  • UN38.3 Certification

Description:  UN38.3 is a standard set by the United Nations (UN) for the safe transport of lithium-ion batteries during transportation by air, sea or ground transportation. UN38.3 refers to the UN Manual of Tests and Criteria, subsection 38.3. It ensures that lithium-ion batteries comply with international regulations (United Nations requirements) for safe transport, including packaging, labeling, and testing requirements for vibration, shock, thermal stability, and transportation safety.

Requirements: Compliance with testing criteria for lithium battery safety during transportation, including mechanical shock, vibration, and environmental tests. Testing for altitude simulation, thermal cycling, vibration, shock, and external short circuit to ensure safe transport.

UN Standards:

  • UN 3480: For lithium-ion batteries.
  • UN 3481: For lithium-ion batteries contained or packed with equipment (applicable in the European Union)3.
