Why UL Marks are Important for Lithium-ion Batteries in Industrial Applications / Walkie Pallet Jacks

Underwriter Laboratories (UL) is an organization whose mission is “to build a safer, more secure and more sustainable today and tomorrow” by helping companies establish trustworthy products in the marketplace. To achieve this mission UL requires products go through rigorous testing by industry-standard UL test labs.

To better understand why UL is important, it is best to understand what certifications are offered and how they differ. Currently UL offers two different certifications detailed below.

UL Listed

Products with a UL Listing have been tested to meet nationally recognized safety standards. They have been tested as complete final products, and found to be free from reasonably foreseeable risk of fire, electric shock and other hazards; and display the UL Listed Mark on product packaging and marketing materials (shown above).

UL Listed lithium-ion walkie pallet truck batteries can be used in all brands currently available, giving the end user a tremendous level of confidence that any equipment will run safely and ensure the protection of employees and property.

UL Recognized Component

Components covered by UL’s “Recognized Component” program are intended to be installed in another device, system or end product and are not a final product. They must be factory installed (no field installation) and they may have restricted performance capabilities that limit their use.

When looking at industrial lithium-ion batteries for walkie pallet trucks, this mark restricts which trucks the battery is compatible with, and further testing of the end product is required to obtain a full UL Listing.


UL Experience and Expertise

UL is the global standard for certifying the compliance and safety of electronic equipment. UL invests its resources in making sure it’s standards are up to date in today’s rapidly changing market ensuring tested products are safe for users. To help maintain trust, UL partners with law enforcement worldwide to seize counterfeit products that attempt to fraudulently bear UL marks.


Why Use a UL Listed Lithium-Ion Battery?

UL Listed lithium-ion batteries are creating a paradigm shift not only in the consumer world, but in the material handling industry as well. The long run times, no maintenance, fast-charge capability and reduced cost of ownership make lithium-ion an attractive choice for industrial equipment such as walkie pallet trucks and forklifts.

As with any new technology, questions about safety arise and it is informative and helpful having a trusted independent third-party such as UL conduct extensive product testing and certification. End users then have confidence in the safety of their employees and operation.
