As the global green energy transition accelerates, the international market demand for batteries—core energy components—continues to grow. However, varying certification requirements across countries have become a major challenge for battery enterprises seeking to export. Guangdong Energy Storage Testing Technology Co., Ltd. points out that CB Certification, as a "passport" for battery products to enter the global market, is playing an increasingly critical role.

I. Understanding the Battery CB Certification System

The CB Scheme is a global mutual recognition system established by the IEC System of Conformity Assessment Schemes for Electrotechnical Equipment and Components (IECEE), with over 50 member countries to date. Guided by the principle of "one test, multiple country recognitions," this system helps battery manufacturers avoid repeated testing and certification in different countries, significantly reducing time and costs.

For battery products, CB Certification is primarily evaluated based on international standards such as IEC 62133 and IEC 62619:

• IEC 62133: Focuses on safety requirements for portable batteries;
• IEC 62619: Emphasizes safety standards for industrial-use batteries.

Obtaining CB Certification means the product complies with international safety norms, laying a solid foundation for entering global markets.

II. Core Value of CB Certification

1. Breaking Through Technical Trade Barriers

Countries impose strict access requirements on imported batteries. With its international credibility, CB Certification enables enterprises to quickly obtain certification in multiple countries, effectively avoiding technical trade barriers. Statistics show that battery products with CB certificates can save approximately 60% of time and 40% of costs when applying for other national certifications.

2. Enhancing Product Competitiveness

In international bidding and procurement, CB Certification has become a standard requirement for high-quality battery products. The certificate conveys a clear message to customers: the product meets international safety standards and is reliable in quality. This third-party endorsement greatly enhances the product’s market competitiveness.

3. Optimizing R&D and Production Processes

The CB Certification process helps enterprises identify potential issues in product design, materials, and manufacturing processes. Through continuous improvement, not only is the product’s safety performance improved, but the overall production process is also optimized, achieving quality upgrades.

4. Accelerating Market Access

With CB Certification reports and certificates, enterprises can quickly convert to certification marks of multiple countries, such as CE (Europe), UL (U.S.), and PSE (Japan). This efficient certification conversion mechanism allows enterprises to quickly respond to market opportunities and seize business prospects.

III. Key Technical Requirements for CB Certification

The evaluation of battery products under CB Certification covers multiple dimensions:

1. Electrical Performance Testing

Includes capacity verification, cycle life, internal resistance distribution, and rate performance testing—ensuring the battery meets practical usage needs.

2. Safety Performance Assessment

• Electrical Safety: Overcharge, over-discharge, short-circuit, and forced discharge tests;
• Mechanical Safety: Impact, vibration, crushing, and drop tests;
• Environmental Safety: Thermal shock, temperature cycling, and low-pressure tests.

3. Critical Component Review

Detailed evaluation of key components such as protection circuits, battery cells, and connectors to ensure the overall system’s safety.

IV. Efficient Path to Obtaining CB Certification

1. Choose an Authoritative Certification Institution

As a professional testing and certification organization, Guangdong Energy Storage Testing Technology Co., Ltd. holds the CBTL (CB Testing Laboratory) qualification recognized by IECEE, providing one-stop CB Certification services. Our expert team is familiar with differences in standards across countries and can offer precise technical guidance to enterprises.

2. Conduct Gap Analysis in Advance

Before formal application, it is recommended that enterprises conduct pre-evaluation testing to identify gaps between their products and standard requirements in a timely manner. Targeted improvements can then be made to increase the certification pass rate.

3. Prepare Complete Technical Documents

Include product specifications, circuit diagrams, lists of key components, and material safety data sheets (MSDS). Comprehensive technical documentation is a crucial guarantee for quickly obtaining certification.

4. Establish a Quality Management System

Ensure the production process continuously complies with certification requirements and make relevant preparations for factory audits (if required).

V. Successful Case Sharing

A well-known lithium battery manufacturer, when expanding into the South Korean market, obtained a CB certificate in just 8 weeks through the CB Certification services of Guangdong Energy Storage Testing Technology Co., Ltd. Based on this certificate, the manufacturer quickly obtained market access permits in Germany, France, and other countries—entering the market 3 months earlier than planned and securing important orders.

VI. Future Outlook

With the rapid iteration of battery technology and changes in the global trade pattern, the importance of CB Certification will further increase. Guangdong Energy Storage Testing Technology Co., Ltd. advises battery enterprises to:

1. Integrate CB Certification into the early stages of product R&D;
2. Establish a comprehensive certification management system;
3. Monitor updates to international standards;
4. Select reliable long-term certification partners.

Conclusion

In the global market competition, CB Certification is not only a "golden key" for battery products to enter the international market but also a reflection of an enterprise’s technical strength and quality management level. Relying on its professional technical team, advanced testing equipment, and rich certification experience, Guangdong Energy Storage Testing Technology Co., Ltd. provides efficient and reliable CB Certification services for battery enterprises, helping Chinese battery products go global.
