AS603030 3.7V 520mAh battery pack has passed UL1642, CB(17), UN38.3, CE and multi-safety inspections .

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.

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.

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.
