South Korea KATS (Korean Agency for Technology and Standard) announced the standard adopted by portable secondary lithium battery packs and lithium batteries: Self-Regulatory Safety Confirmation, Annex 05, which was formally implemented on July 1, 2009. At present, the testing of portable secondary lithium battery packs and lithium batteries must be performed by authorized laboratories in South Korea, and it is not possible to use the IEC62133 CB report to correct. After the product has passed the evaluation, a certificate of conformity declaration valid for 5 years will be issued(Confirmation Letter of Declaration), during which no factory inspection is required. All KC certification procedures need to be completed in South Korea. AGC Battery Division has very good partners who can smoothly help you obtain product certificates.
