OverviewSafetyHistoryElectrochemistryMeasuring the charge levelVoltages for common usageConstructionApplications
Excessive charging causes electrolysis, emitting hydrogen and oxygen in a process known as gassing. Wet cells have open vents to release any gas produced, and VRLA batteries rely on valves fitted to each cell. Catalytic caps are available for flooded cells to recombine hydrogen and oxygen. A VRLA cell normally recombines any hydrogen and oxygen produced inside the cell, but ma…
