Answer - C - Always refer to the manufacturer’s instructions to dispose of the battery using the correct procedure.

Key Takeaway: A battery contains strong corrosive acids and harmful chemicals like lead, cadmium, mercury and nickel. Disposing of a battery in the open may cause environmental hazards like:

-Polluting the lakes and streams as the metals vaporize into the air.
-Contributing to heavy metals that potentially leach from solid waste landfills.
-Exposing the environment and water to lead and acid.
-Causing burns or danger to eyes and skin.

It is extremely important to refer to environment organization websites and manufacturer's documentation to know the proper disposal procedures.
