AS553640 3.7V 850mAh battery pack has passed UL1642, UL2054, CB(17), CCC, KC, UN38.3, WERCS, CE and multi-safety inspections.

CE: Conformité Européenne (CE) certification is a regulatory standard that verifies certain products are safe for sale and use in the European 

Economic Area (EEA). Manufacturers place a CE marking on certified products to indicate that the product complies with European safety 

rules and can be traded freely within the EEA.

UL1642 certification is essential for manufacturers and consumers of batteries, as it signifies that a battery has undergone thorough testing 

and meets safety criteria for consumer electronics, electric vehicles, and medical devices. The certification requirements cover lithium-ion 

batteries to avoid the risk of fire or explosion when they are used in products.

UL2054 certification requirements cover portable primary (non-rechargeable) and secondary (rechargeable) lithium-ion batteries for use as 

a power supply in goods. These lithium-ion batteries consist of either a single electrochemical cell or two or more lithium-ion cells connected 

in parallels or series, or both, that convert chemical energy into electrical energy by chemical reaction.It intends to reduce the risk of explosion 

or fire when lithium-ion batteries are working in a device. The proper use of these lithium-ion batteries in a particular application is dependent 

on their use in a complete product that complies with the requirements applicable to such a product.

CB certification is a globally recognized certification scheme that allows products to be sold in over 50 countries. It's issued by a certification 

body (NCB) under the IECEE (IEC System for Conformity Testing and Certification of Electrical and Electronic Equipment).

UN 38.3 details environmental, mechanical, and electrical requirements for all lithium cells and batteries. Manufacturers of lithium batteries 

and products using lithium batteries must demonstrate compliance in the design, manufacturing and distribution of their products to ensure 

the safety of lithium batteries during transportation.

WERCS, or Worldwide Environmental Regulatory Compliance Solutions, is a company that helps manufacturers and distributors in the 

electrical and electronics sector comply with environmental regulations.

KC certification, or Korea Certification, is a product certification which ensures the conformity of products to Korean safety standards – called 

K Standards. The KC Certification (KC Mark Korea Certification) focuses on prevention and reduction of risks regarding safety, health or 

impact on the environment.

CCC: The China Compulsory Certification is a mandatory certification including product testing in China, an initial factory audit and 

subsequent annual follow-up inspections for products that are listed in the CCC catalogue.
