When a lead-acid battery runs out of water, it can cause the battery to fail prematurely. When this happens, the electrolyte level inside the cells begins to decrease and eventually will be depleted unless additional water is added to refill them. This process causes corrosion on the cell plates and leads to sulfation which drastically reduces
