What are AGM Batteries?

AGM batteries differ from flooded lead acid batteries in that the electrolyte is held in the glass mats, as opposed to freely flooding the plates. Glass fibres are woven into a mat to increase surface area enough to hold sufficient electrolyte on the cells for their lifetime.
