With the popularization of electronic devices and the rapid development of the new energy industry, batteries— As core energy components—have attracted significant attention regarding their safety and reliability. In China, batteries such as power banks and lithium-ion batteries for electric bicycles must obtain Compulsory Product Certification (3C Certification) to be sold in the market. As a professional testing and certification institution, Guangdong Energy Storage Testing Technology Co., Ltd. is committed to providing comprehensive and efficient 3C certification services for battery enterprises, helping them enhance product competitiveness and safeguard consumer safety.

I. What Is 3C Certification?

3C Certification, officially known as "China Compulsory Product Certification," is a conformity assessment system implemented by the Chinese government to protect consumers’ personal safety and national security, and strengthen product quality management. For battery products, 3C Certification is a critical market access threshold—batteries that fail to obtain certification are prohibited from being sold or imported in China.

The scope of 3C Certification for batteries mainly covers portable lithium-ion batteries, particularly widely used products such as lithium-ion batteries and power banks. Obtaining 3C Certification means the battery product complies with national standards in terms of safety performance, environmental adaptability, and electrical characteristics.

II. The Importance of Battery 3C Certification

1. Safeguarding Consumer Safety

As high-energy carriers, batteries pose risks such as overheating, short circuits, fire, or even explosion if improperly designed or manufactured. Through rigorous testing, 3C Certification ensures that battery products remain safe and stable during normal use and fault conditions, effectively reducing the probability of accidents.

2. Complying with Legal and Regulatory Requirements

According to the Administrative Regulations on Compulsory Product Certification, battery products without 3C Certification are not allowed to be sold in China. Enterprises that violate this regulation face consequences such as product removal, fines, or even legal liability. Obtaining certification is a basic prerequisite for enterprises to operate legally.

3. Enhancing Market Competitiveness

The 3C Certification mark is a symbol of product quality, which strengthens consumer trust and helps enterprises expand their markets. Especially in the highly competitive electronic product and new energy sectors, certified products are more likely to be favored by customers and partners.

4. Promoting Industry Technological Upgrading

3C Certification requires enterprises to continuously optimize product design and production processes, thereby driving the improvement of the industry’s overall technological level. Through the certification process, enterprises can identify and resolve potential product issues in a timely manner, improving product quality and reliability.

III. Testing Content for Battery 3C Certification

The testing items for battery 3C Certification are comprehensive and rigorous, mainly including the following aspects:

1. Electrical Performance Testing

Covers tests for capacity, cycle life, internal resistance, and charge-discharge performance. These ensure the battery performs stably in practical use and meets user needs.

2. Safety Performance Testing

Includes short-circuit testing, overcharge/over-discharge testing, high-temperature testing, and mechanical impact testing. These simulate extreme usage conditions to verify the battery’s safety and durability.

3. Environmental Adaptability Testing

Encompasses high-low temperature cycling, damp-heat testing, and vibration testing. These evaluate the battery’s performance under different environmental conditions.

4. Chemical Testing

Detects the content of hazardous substances in the battery to ensure the product complies with environmental protection requirements.

IV. How to Efficiently Obtain Battery 3C Certification?

1. Choose a Professional Testing Institution
