UL 4200A:2021 PDF Download

UL 4200A:2021 is a standard that specifies safety requirements for household type products that incorporate or may use button or coin cell batteries of lithium technologies. The standard covers the use of lithium button or coin cells in consumer products, but it does not apply to products that exclusively use other types of batteries.

The scope of the standard is limited to products intended for household use and does not cover products designed for dedicated professional use or commercial use where children are not normally present.

It is important to note that UL 4200A:2021 is meant to supplement other safety requirements for products that incorporate button or coin cell batteries and does not replace specific requirements outlined in other safety standards. The purpose of this standard is to ensure the safe use and operation of products containing button or coin cell batteries, addressing potential physiological hazards associated with these types of batteries.
