The SSBS are normally housed in a room as a part of a main building or as a standalone enclosure. Typical battery SSBS are composed of batteries of the flooded lead-acid batteries, Valve Regulated Lead-Acid (VRLA), or nickel-Cadmium (Ni-Cd) batteries, a battery charger, rectifiers, inverters, converters, and associated electrical equipment.
