Valve Regulated Lead Acid Battery

5 Valve-regulated lead–acid batteries with absorptive glass mat separators. The great majority of VRLA batteries produced, either as cells or as monoblocs, use pasted plates with Pb-Ca-Sn grids and AGM separators ( Fig. 5 ). Sizes range from 12 V, 1 Ah monoblocs to single cells with a capacity of 4000 Ah or more.
