UL 1989:2018 PDF Download

The UL 1989:2018 standard covers the requirements for valve regulated or vented batteries used in various applications such as instrument batteries, enclosed batteries, emergency lighting and power batteries, and uninterruptible power supply batteries. It specifically addresses the unique risks associated with using battery supplies in products.

The standard focuses on aqueous electrolyte valve regulated or vented batteries, including lead acid, nickel-metal hydride, nickel zinc, or nickel cadmium, among others. However, it does not cover the risks associated with lithium batteries, such as fire and explosion risks. Lithium batteries are outside the scope of this standard, and their specific requirements are addressed in other standards.

The investigation of a family or group of batteries can be based on the investigation of representative batteries from that family or group.
