Free Battery Drop off. Household batteries contain at least 22 toxic elements including mercury, lead, cadmium, and more. Recycle your old household batteries by dropping them off at our treatment plant or at the Marin Sanitary Hazardous Waste drop-off location or at any County of Marin Bulb and Battery Take Back Locations 

Please make sure to tape the terminals first with either duct, masking or scotch tape. We cannot accept untaped batteries as the Department of Transportation no longer allows waste haulers to transport them without this additional step. Thank you!!
