With the in-depth implementation of the "Safety Technical Specification for Lithium-ion Batteries and Battery Packs for Portable Electronic Products" (GB 31241-2022), starting from 2026, batteries and power banks without CCC certification are strictly prohibited from being manufactured and sold. The editor of Chengce Battery Certification Institution will provide a detailed interpretation of the new standard requirements, applicable scope and specific processing steps for battery 3C certification.

I. Which batteries need to obtain 3C certification?
According to the Compulsory Product Certification Catalogue released by the Certification and Accreditation Administration of the People's Republic of China, the current scope of supervision mainly includes
Lithium-ion batteries and battery packs for portable electronic products: such as mobile phone batteries, laptop batteries, tablet computer batteries, Bluetooth headset batteries, wearable device batteries, etc.
Power banks (Class 0914) : including power banks, portable energy storage power sources (mass ≤18kg), camping power banks, etc.
Note: Batteries for electronic cigarettes are not currently included in the list of mandatory 3C certification, but they must comply with relevant industry standards.

Ii. Core Changes of the New 3C Certification Standard for Batteries (GB 31241-2022
The focus of compliance checks in 2026 has shifted to the GB 31241-2022 standard. Compared with the old version, the new standard has put forward higher requirements in terms of security:
Overcharge protection upgrade: The test voltage is raised to 1.3 times the charging limit voltage, and a dual protection circuit is required.
New lithium plating detection: Conduct lithium plating detection on batteries after 300 charge and discharge cycles to strictly prevent the risk of thermal runaway after long-term use.
Mandatory marking of safety period: Power banks must prominently mark "Recommended safe service life" to remind consumers to replace old products in a timely manner.
Traceability uniqueness: The product must have a unique code, covering the information of the battery cell manufacturer, to achieve full life cycle traceability.

Iii. Illustrated Process for Obtaining 3C Certification for Batteries
Certification application: Submit the application form online to the certification body designated by the Certification and Accreditation Administration of the People's Republic of China (such as CQC, CESI, etc.).
Document review: The institution conducts an initial review of the business license, product manual, and list of key components (battery cells, protection boards, MOSFETs, etc.).
Sample submission for testing: Send the samples to a qualified laboratory to conduct environmental tests, electrical safety tests and battery pack protection circuit tests in accordance with GB 31241-2022.
Factory inspection: Auditors conduct on-site verification of the quality assurance capabilities of manufacturing enterprises (some small and micro enterprises may apply for simplified procedures in 2026).
Assessment and Certification: After passing the inspection and factory audit, a CCC certification certificate will be issued.

Iv. List of Core Materials Required for Application
Basic proof: Business licenses and organization code of the applicant, manufacturer and production plant.
Technical documents: Product specification sheet, circuit diagram, assembly drawing, Chinese nameplate (including rated energy Wh, production date, etc.).
List of key components: including battery cell specifications, protection IC model, fire resistance rating certificate of the casing, etc.
Quality documents: Description of factory quality assurance capability or ISO 9001 system certificate (if any).

V. Suggestions from CCJC Certification Body: How to Increase the Audit Pass Rate?
Battery cell first: Ensure that the battery cells used have obtained separate CCC certification in advance or meet the requirements of GB 31241. This can significantly shorten the certification cycle of the entire machine.
Marking standards: Starting from 2026, customs and market inspections will impose very strict requirements on the font size and rated capacity marking method of Chinese markings. It is essential to strictly design and layout in accordance with the standards.
Pre-test: Conduct simulated overcharge and squeeze tests before the official sample submission to avoid additional costs resulting from retesting due to non-compliance.

The 3C certification for batteries is not only a legal document for entering the market, but also a strong endorsement for product safety. In the highly competitive market of 2026, obtaining licenses and permits as early as possible is the core competitiveness for enterprises to avoid the risk of delisting and win the trust of consumers.
