There are three main types of UPS batteries: valve-regulated lead–acid (VRLA), flooded cell or VLA batteries, and lithium-ion batteries. The run-time for a battery-operated UPS depends on the type and size of batteries and rate of discharge, and the efficiency of the inverter. The total capacity of a lead–acid battery is a function of the rate at which it is discharged, which is described as Peukert''s law.
