CB Certification for Lithium Batteries

Product Scope of cb certification for Batteries

CB certification covers portable sealed secondary cells and batteries that contain alkaline or non-acid electrolytes, including:

- Nickel cells

- Nickel batteries (packs)

- Lithium-ion cells

- Lithium-ion batteries (packs)

- Rechargeable batteries and battery packs used in portable devices

Key Considerations for CB Certification

1. cb test Certificate Application

 - The CB test certificate can be applied through any National Certification Body (NCB) that covers the relevant product category.

 - The applicant may be the manufacturer or an authorized representative of the manufacturer.

 - If the applicant, manufacturer, or factory is located in a country without an IECEE member body, an additional fee must be paid per cb certificate to cover system operation costs. This fee is collected by the issuing NCB and paid to the IECEE.

 - Applicants may request testing for national differences according to the target country.

2. Certification Process for Target Markets

 - Submit an application to the certification body in the destination country.

 - Provide the CB Test Certificate.

 - Provide the cb test report (including national differences, if applicable).

 - If required by the destination country’s NCB, submit product samples.

 _Note: The sample submission helps verify that the product matches the version tested by the issuing NCB and that all national differences are covered._

3. National Differences

 - These refer to deviations between national regulations or standards and the corresponding international standards. All CB Scheme countries must submit their national differences to the IECEE Secretariat. These are published in the CB Bulletin.

4. No Factory Inspection Required

 - CB certification does notrequire a factory inspection.
