UL 810A:2017 PDF Download

The UL 810A:2017 standard establishes requirements for electrochemical capacitors used in various applications such as electronic products, uninterruptible power supplies, emergency lighting, engine starting, and power equipment. The standard covers energy storage capacitors that are also referred to as "electric double layer capacitors," "ultracapacitors," "double layer capacitors," or "supercapacitors." These capacitors can be individual units or multiple units connected in series and/or parallel with or without associated circuitry.

It is important to note that the UL 810A standard does not encompass electrochemical capacitors designed for use in hazardous or classified locations. These specific applications are excluded from the scope of this standard.
