When it comes to lithium batteries, people might first think of the models in mobile phones and power banks. However, in devices such as power tools and smart home appliances, the 2650 battery is a "practical player". It has a diameter of 26mm and a height of 50mm. Its capacity and discharge performance are suitable for a variety of small and medium-sized devices. Many enterprises will sell it to the global market, and the CB certification is an important pass for its "going global" and compliant sales.
First, understand: What is a 2650 battery?
The 2650 battery is a type of cylindrical lithium battery, named for its size (26mm in diameter × 50mm in height). Unlike mobile phone batteries that pursue extreme compactness, it focuses more on "stable battery life and wide adaptability", and is commonly found in portable small household appliances, outdoor lamps, small power tools and other products. Nowadays, many enterprises sell products equipped with 2650 batteries to different countries. At this point, CB certification becomes an unavoidable step.
Ii. Why do 2650 batteries need to obtain CB certification?
1. Open up market access in multiple countries: CB certification is a global mutual recognition system of the International Electrotechnical Commission (IECEE). After obtaining the certificate, when going to multiple countries/regions such as the European Union, the United States, and Japan, only a small amount of local difference tests need to be supplemented, and it can be quickly converted to local certification (such as EU CE, US UL), without having to repeat the full set of tests.
2. Enhance customer trust: Whether it's overseas distributors or end users, seeing the CB certification mark will make them more convinced of the product's safety performance - after all, the certification process will test various safety scenarios such as overcharging, short circuits, high and low temperatures, which is equivalent to providing a "guarantee" for the product's safety.
3. Reduce compliance risks: Nowadays, many countries have increasingly strict safety requirements for battery products. Products without authoritative certification may face the risks of being detained by customs and failing market spot checks. CB certification can help enterprises avoid these problems in advance.
Iii. What documents are needed to apply for CB certification?
1. Basic product information: Specification sheet of 2650 battery (such as capacity, voltage, charging current, etc.), structure diagram (marking the positions of key components), appearance photos;
2. Enterprise qualifications: Copy of business license (if it is entrusted certification, an entrustment agreement is also required);
3. Testing-related: Battery cell specifications, protection circuit design description (Some institutions may require samples, please refer to the specific requirements).
Iv. The process for obtaining CB Certification for 2650 Batteries
1. Consultation and confirmation: First, communicate with the certification body (such as China Certification Union) to clarify the specific model of the 2650 battery, the testing standard (usually IEC 62133), and confirm the required documents and fees;
2. Submit materials and samples: Send the prepared materials and samples to the institution. The institution will first verify whether the materials are complete and whether the samples meet the testing requirements.
3. Laboratory testing: The institution conducts safety tests in accordance with standards, such as overcharge tests, temperature cycling tests, short-circuit tests, etc. After passing the tests, a test report will be issued.
4. Certificate Review and Issuance: After the test report is verified to be correct, the CB certification certificate will be issued. The entire process usually takes 4 to 6 weeks (the exact time depends on the test situation and the speed of document preparation).
In conclusion, for 2650 batteries to be more popular in the global market, CB certification is a very practical boost - it not only helps the product comply with market access regulations but also gives customers a sense of security. If enterprises still have doubts about the certification process, seeking assistance from professional testing and certification institutions can save them a lot of detours.
