Many batteries contain toxic chemicals like mercury, nickel, and cadmium. If such batteries end up in a landfill, those chemicals can leach into the soil or water system. Always take rechargeable batteries to your nearest local recycling drop-off, which you can find at Call2Recycle. Although alkaline batteries are less harmful, homeowners should still deliver them to a Household Hazardous Waste (HHW) facility for safe disposal.
