Safety assurance: UL 1973 demonstrates that a battery system can resist hazards such as thermal runaway, fire, and electrical faults. Regulatory compliance: Building codes and standards, such as NFPA 855, reference UL 9540 as the system-level requirement. To achieve UL 9540, the battery subsystem must already meet UL 1973.
UL1973 (the Standard for Batteries for Use in Stationary, Vehicle Auxiliary Power and Light Electric Rail (LER) Applications) is a safety standard for energy storage systems. It specifies detailed requirements that manufacturers of ESS must meet to qualify for safety certification.
The risks of failing to meet UL 1973 requirements are significant. A battery system without certification cannot be legally marketed or deployed in most of North America. Beyond that, uncertified systems may struggle to secure insurance, financing, or regulatory approval.
UL 1973 is the gold standard for battery safety in energy storage. For developers and C&I customers, certification ensures regulatory approval, market access, and system reliability. EticaAG’s immersion cooled lithium ion battery racks are now UL 1973:2022 certified, delivering unmatched protection against thermal runaway and fire propagation.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
