AS552540 3.7V 540mAh battery pack has passed UL1642, IEC(17), UN38.3, 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.

IEC: International Electrotechnical Commission creates and publishes international standards for electrical, electronic, and related 

technologies. The IEC's standards cover a wide range of technologies, including power generation, transmission, and distribution, as 

well as home appliances, office equipment, semiconductors, and more.

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.
