AS502030 3.7V 250mAh battery pack has passed UL1642, BIS, 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.

UN38.3: Battery chemistries that are lithium-based must undergo UN38.3 testing requirements before being transported. This testing certifies that 

the batteries are safe and will not pose a safety risk during shipping over air, water, rail, or road transportation methods.

WERCS: It stands for Worldwide Environmental Regulatory Compliance Solutions. Manufacturers submit regulatory information to WERCS for 

certification.This information allows retailers to understand the requirements for shipping, handling, storing, and disposing of WERC-certified 

products. It also aids in a retailer’s sustainability goals and compliance with all federal, state, and local regulations.

Bureau of Indian Standards (BIS): The national standards body of India, responsible for the development and implementation of standards for 

various products and services.
