"KC" certification is a national unified certification mark implemented by the Korean National Standards Committee, and lithium batteries are included in the KC certification catalog as a compulsory certification product.

Ⅰ.Scope of KC certification for battery products

1. Single battery: carrying;
2. Battery: single cell straight parallel assembly manufacturing;
3. Lithium single batteries with navigation functions or batteries that have nothing to do with the energy density per volume are applicable objects;
4. Single batteries and batteries used in portable medical devices, barcode and credit card readers and other products are applicable;
5. Portable machines: MP3, electronic dictionary, PMP, laptop, digital camera, etc.;
6. Breakdown of portable products: batteries used in mobile products also belong to the certification object;
7. Non-certification objects: vehicle drive, industrial, medical.

Ⅱ.Lithium battery to do KC certification precautions

1. Models cannot be applied for in the same institution.
2. KC certificate does not accept any changes involving the basic model, if you need to change the certificate:
A.Only the series models can be considered
B. You can only cancel the original certificate and reapply
3. It is recommended that lithium battery products do not directly apply for KC certification, but can apply for CB certification first, and then use CB certification to convert to KC certification, which has the following benefits:
A. The fees are comparatively cheaper. The cost of KC directly is more expensive, and it is necessary to send samples to South Korea for testing, which increases the courier fee and the difficulty of certification. By doing CB first, and then using CB to apply for KC certification, the cost is relatively cheaper, and there is no need to send samples to Korea.
B. The cycle is comparatively shorter. To do KC certification directly, you need to send samples to South Korea for testing, and the sample plus test cycle basically takes more than 3 months, while through CB to apply for KC, CB certification cycle is 3-4 weeks, and it only takes a few weeks to transfer to KC, and KC certification can be done in more than a month, which is more efficient.

Ⅲ.Updates to the KC 62133-02 (2020) regulation for the certification requirements for coin cell batteries

On January 4, 2021, KATS clarified the requirements for rechargeable button batteries to apply for KC safety certification in South Korea. Batteries with pouch shape and thickness smaller than diameter fall within the scope of KC 62133-02 (2020).
