Safety Features

AS352728 3.7V 240mAh battery pack has passed CE, CB(IEC62133), UN38.3 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.

CB: The IEC has established an arrangement for the mutual acceptance of test reports in the field of electrical and electronic equipment: the 

IECEE Certification Body(CB) Scheme.

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.
