What Does the UL 1973 Designation for Lithionics Batteries Used in Winnebago RVs Mean?    

Winnebago equips many of its motorhomes with Lithionics lithium batteries, recognized for their quality, reliability, and safety. When you’re exploring off-grid destinations, having a power system that performs consistently and safely under pressure is essential – and Lithionics batteries deliver exactly that. These advanced lithium battery systems are featured in a range of Winnebago models, including the Winnebago Revel, Winnebago Travato 59KL, Winnebago EKKO, Winnebago View & Navion, and Winnebago Vista and Sunstar National Park Foundation Limited Edition. Each of these models incorporates UL 1973 Certified Lithionics lithium batteries. The UL 1973 designation highlights compliance with rigorous safety and performance standards. So what does this mean?  Continue reading to find out.

UL 1973 is a safety certification standard developed by Underwriters Laboratories that applies to stationary and motive battery systems. Lithionics lithium batteries are the first in the industry to achieve full UL 1973 certification for both stationary (i.e. energy storage) and moving applications (i.e. RVs), ensuring the lithium batteries in your Winnebago motorhome are safe and dependable.  

The only way to obtain this certification is through extensive testing. The testing process to obtain this certification is not only lengthy, but expensive. UL testing evaluates the electrical, mechanical, structural and environmental safety of battery modules and packs. The big takeaway from the UL Testing is that Lithionics batteries are engineered for exceptional safety and reliability – even under extreme conditions.  Whether they are dropped, punctured, submerged, or burned, these batteries demonstrate that they will not catch fire, explode, enter thermal runaway, or leak hazardous materials. Their performance under stress highlights the robust engineering behind their safety design.

Whether you’re thinking about buying an RV with lithium power or upgrading your current battery system, safety should lead your decision-making process. You can travel in your Winnebago RV with full confidence knowing Lithionics goes beyond the industry standard to obtain UL 1973 Certification.
