Battery CQC certification standards and test content——ZRLK

The CQC mark certification is one of the voluntary product certification services carried out by the China Quality Certification Center. The application of the CQC mark indicates that the product meets the relevant quality, safety, performance, electromagnetic compatibility and other certification requirements. The certification scope involves mechanical equipment, electrical equipment , Electrical appliances, electronic products, textiles, building materials and more than 500 products. The CQC mark certification focuses on safety, electromagnetic compatibility, performance, hazardous substance limit (RoHS) and other indicators that directly reflect product quality and affect the personal and property safety of consumers. It aims to protect the interests of consumers, promote the improvement of product quality, and enhance domestic enterprises’ Competitiveness.

The importance of battery CQC certification

CQC certification is a voluntary product certification, but companies applying for CQC certification have greatly improved the quality of their products:

1. The product has passed the CQC certification, indicating that the company's products fully meet or exceed the relevant national or industry standards, which greatly improves the company's image and product quality;

2. Many types of CQC certified products are components. If the company's products have passed the CQC certification, then the customer's complete product does not need to be repeated random tests for finished product certification. On the one hand, it can save test costs, and on the other hand, it can reduce test risks;

3. With the improvement of people's living standards, consumers have higher and higher requirements for product quality and safety, and certified products are more likely to be favored by consumers.

Battery CQC certified product range

Examples of lithium-ion batteries and battery packs for portable electronic products to which the battery CQC certification GB31241 standard applies are as follows:

1. Portable office products: notebook computers, PDAs, etc.;

2. Mobile communication products: mobile phones, cordless phones, Bluetooth headsets, walkie-talkies, etc.;

3. Portable audio/video products: portable TVs, portable DVD players, MP3/MP4 players, cameras, camcorders, voice recorders, etc.;

4. Other portable products: electronic navigator, digital photo frame, game console, e-book, etc.

The above list is only an example, and portable electronic products include the above listed products, but are not limited to the above products.
