✦ Synopsis

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 systems of the same design is inferior. Additional advantages of VRLAs are: absolutely maintenance-free operation during battery service life; very low self-discharge; ability to be used in any position; excellent charge acceptance; deep-discharge resistance: Furthermore, the VRLA system may be designed to meet stated, specific requirements. Different test results show that VRLAs with AGM separators can be used for standby, automotive, and deep-discharge cycling applications.
