## Several characteristics of the well-known lead/acid battery can be improved by developing valve-regulated units (VRLAS) with absorptive glass mat (AGM) separators. In spite of the fact that antimony-free alloys are used, very good cycle-life is achieved. The performance of conventional flooded

Valve-regulated lead/acid (VRLA) batteries provide the very high levels of reliability required for standby service. Various types are available, in particular: cells with lead-calcium-tin alloy grids and absorptive glass-mat (AGM) separators; cells with pure lead grids and AGM separators; cells wit
