Battery Certification Introduction | UL & IEC

In today’s rapidly evolving market, where technological advancements are shaping every facet of our lives, the need for stringent quality control and safety measures cannot be emphasized enough. The surge in demand for batteries, especially in applications ranging from portable electronics to electric vehicles, has ushered in a crucial aspect of product certification – battery certification.

Why battery certification is necessary

Definition of battery certification

The activity of a third party that can be trusted to verify that a product or service complies with a specific standard or other technical specification.

Battery certification is divided into compulsory certification and voluntary certification.

Purpose of battery certification

If an enterprise’s product has passed the product certification of the famous national certification body, it can obtain the “certificate of authentication” issued by the national certification body, and allow the certification mark to be affixed to the certified product.

This internationally recognized and effective certification method can enable enterprises or organizations to establish a good reputation and brand image through product certification. At the same time let customers and consumers to identify the quality and safety of goods through certification marks.

At present, governments around the world have established such a product certification system through the form of legislation to ensure the quality and safety of products and safeguard the vital interests of consumers. This has become a new international trade barrier.

National battery standard system


IEC Standards system

The IEC standard is developed by the IECEE (International Electrotechnical Commission), and implemented by its accredited qualified organizations or third-party laboratories, currently the mainstream UL/CSA/TUV/SGS/Intertek/BV/Nemko.
IECEE Committee for the member states to develop a CB system, IECEE member states certification bodies to IEC standards based on the safety performance of electrical products for testing, the test results that CB test reports and CB test certificates, in the IECEE member states to get mutual recognition of the system.
The purpose is to reduce barriers to international trade arising from the need to meet different national certification or approval criteria.

UL listed system

UL (underwrite lab) is both the U.S. product safety testing and certification organization, but also the founder of the U.S. product safety standards.
Its ultimate goal is to get for the market with a considerable level of safety of goods, to ensure the safety of human health and property to contribute to the product safety certification as an effective means of eliminating technical barriers to international trade.
The UL system can be described as a system of access to two markets, including Canada.

Battery Certification Process and Precautions

UL Certification Process

  1. Submission of company and product information by the applicant
  2. Based on the product information provided, determine: UL standards, engineering costs of testing, time of testing, number of samples, etc.
  3. Product testing (generally directly in the UL test, or UL authorized testing qualification of third-party laboratories)
  4. If the test passes, UL will issue a test report and tracking service details (the test report will detail the test situation, samples to achieve the indicators, product structure and safety signs suitable for the use of the product, etc.). Follow-up service details include a description of the product and instructions to the UL regional inspector)
  5. Factory audit, audit passes, the applicant is authorized to use the UL logo
  6. Post-license supervision

Certification Application Information

Specification – product name, model number, specifications are consistent with the application form
Circuit diagram – bit number is consistent with BOM
Layout drawings, BOM lists – key parts lists, product structure drawings (UN certification is not required)
Instruction manual – corresponding to the language of the country or region, pay attention to the warning language requirements and font size requirements
Product labeling – Voltage and capacity labeling to meet the requirements of the battery indicator code, must correspond to the national language, pay attention to the size of the certification mark requirements. CB labeling examples are as follows:

cb label

Certification Sample Preparation

  • Finalized samples as far as possible
  • For UN testing, you need to consider disengaging the communication to facilitate the test.
  • Consider preparing several unsealed, unglued samples.
  • Have enough test ports and accessories, such as charging and discharging cables and chargers.
  • The product should have the final shipping label (especially important for UN certification).

UL certification auditing requirements

Requirements for factory inspection:
Before the first factory inspection, the factory should prepare the following documents for inspection:

  • Company organization chart
  • Quality control flow chart
  • Production flow chart
  • Product change flow chart or document
  • QC personnel and key personnel training records
  • Documents related to incoming material inspection (e.g. standards, work instructions, etc.)
  • Process (production) inspection related documents
  • Documents related to shipment inspection
  • Equipment management related files (such as calibration certificates, equipment account, etc.)
  • Non-conforming goods control

Annual Factory Inspection
The annual factory inspection requires the preparation of data and the process is basically the same as the first factory inspection, but the annual factory inspection must be carried out product consistency check, factories need to submit the required documentation for consistency check, the specific requirements of the factory inspection user manual.

Note: Most types of products are inspected at least four times a year, the inspector’s inspection is to ensure that the product continues to be consistent with the UL requirements, before you plan to change the structure or components of the product, please notify UL, for small changes do not require the repetition of any experiments, UL can quickly modify the rules of tracking service, so that the inspector can accept such changes. When UL believes that the changes affect the safety performance of the product, it is necessary for the applicant company to resubmit samples for the necessary tests.

UL certification audit content

Approved methods and records for major equipment

Internal approval methods and records

8. Certified products consistency test (for annual inspection)

Whether to retain and be able to provide UL-issued CDF, photos and copies of certificates

Whether to retain and be able to provide records of conformance checks carried out within the factory

Arrangements for the production of certified products or in the warehouse to retain the pre-production of certified products

UL inspectors check with structural and photographic data for discrepancies or safety violations.

Precautions for UL certification

  • When applying for UL certification, the applicant must find a third-party laboratory authorized by UL for processing
  • Receiving the confirmation letter of passing the test does not mean that you have obtained the UL certificate. Please be sure to pass the factory inspection before shipping to the United States
