BEST technical editor Dr Mike McDonagh provides an overview of the properties of AGM separators that are required to produce VRLA lead-acid batteries. As markets evolve, higher energy throughput and better charge-discharge efficiency will make the storage technology more attractive, particularly where ROI is king.
VRLA AGMs are basically lead-acid batteries with the same requirements as the flooded variety to deliver voltage and capacity. Where they differ is that they have the added feature of preventing or reducing water loss by recombining hydrogen and oxygen released . . .
