Thecertification in North America for lithium battery 

InNorth America, Lithium battery is not within the limited product range of NRTL,namely it does belong to mandatory products for certification. However, thelocal people will not buy product without safety mark, because of their strongsafety consciousness. So it’s necessary to apply the testing and certification,or the product will have difficulty in entering the market of North America.
