Universally recognized as the global leader in battery safety testing, UL helps battery product manufacturers gain fast, unrestricted access to the global market.

UL not only tests and certifies batteries, but also contributes to the development and international harmonization of industry safety and performance standards.

UL Certifications of Lithium Battery


What is Underwriters Laboratories (UL) ?

UL is an independent product safety certification organization which, in conjunction with other organizations and industry experts, publishes consensus-based safety standards.  For lithium batteries, key standards are: UL 1642 (Lithium Batteries) – This standard is used for testing lithium cells.  Battery level tests are covered by UL 2054.  UL2054 (Household and Commercial Batteries) – For lithium batteries, UL 2054 defers all component cell level testing to UL 1642. UL 2580 (Batteries for use in Electric Vehicle


What is UL 1642 (Lithium Batteries)?

UL 1642 (Lithium Batteries) – This standard is used for testing lithium cells. Battery level tests are covered by UL 2054. ... IEC 62281 (Safety of primary and secondary lithium cells and batteries during transport) This standard is similar to UN/DOT 38.3.


What is UL 2054 (Lithium Batteries)?

UL1642 deals with individual cells while UL2054 is for small rechargeable battery packs. ... Although UL2054 is not a mandated test for products shipped into the US, it is often mandated by US end device standards and it is a pretty severe test as it requires a single fault to be applied on the battery pack


Why is Battery Safety Testing Important?

Mobile devices have become essential tools for business and leisure. The safety, efficiency and reliability of the batteries that power cellphones and other devices play a key role in continued market growth. UL offers more than 30 years’ experience in battery performance testing, helping to foster innovation and boost confidence in quality.
