Recycling household batteries is preferable to disposal. Most batteries contain harmful substances such as mercury, cadmium and lead. If they go to landfill these might contaminate the land or groundwater. Three companies in Australia reprocess old batteries to extract sulfuric acid, lead and plastic casing to sell.
