VRLA battery

OverviewConstructionHistoryBasic principleAbsorbent glass mat (AGM)Gel batteryApplicationsComparison with flooded lead-acid cells

Each cell in a VRLA battery has a pressure relief valve which will activate when the battery starts building pressure of hydrogen gas, generally a result of being recharged. The cell covers typically have gas diffusers built into them that allow safe dispersal of any excess hydrogen that may be formed during overcharge. They are not permanently sealed, but are designated to be maintenance free. They can be oriented in any manner, unlike normal lead-aci…
