Battery CQC certification

The importance of battery CQC certification

In view of the current national policies and a series of urgent requirements, whether you are a complete machine manufacturer or a large battery and mobile power manufacturer, distributor or trader, as long as the product is sold in the domestic market, you need to do CQC or GB31241, GB/T 35590 report. Batteries, mobile power supplies, etc. must be listed on Taobao Tmall Jingdong, and the commissioned inspection reports of GB31241 and GB/T 35590 are also required. Now customers have more and more stringent requirements for supplier battery products and mobile power supplies. Battery products and mobile power supplies have undergone CQC certification, which is conducive to increasing the brand awareness of certified products, enhancing product market competitiveness, and increasing market share.

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, but are not limited to, the above products.
