The U.S. EPA estimates that more than 350 million rechargeable batteries, made of heavy metals like nickel cadmium, lithium ion, mercury, nickel metal hydride and lead acid, are bought each year in the United States. If they are not properly managed, these elements can:
Pollute the lakes and streams
Cause issues at solid waste landfills
Bring lead and acid into the environment and water
Expose corrosive acids
Burn or harm the eyes and skin
Battery users must take responsibility for protecting the environment. Be sure to return your spent battery when you purchase a new one. You can always contact your local government or local battery supplier for additional information.
