Batteries are banned from the trash and are considered universal household hazardous waste as indicated from the State of California Department of Toxic Controlsl. They are considered hazardous because they contain metals and other toxic and corrosive chemicals (such as manganese, cobalt, and nickel) that can leak into the environment from the landfills, and soak into the soil and water supply and ecosystems. As a result, plants, birds, and animals that may be exposed are unable to survive. In addition, if batteries are not properly secured and disposed of properly, they can cause fires and then cause air contamination. All batteries, including sizes AAA, AA, C, and D, need to be disposed of as Household Hazardous Waste.

As a resident of West Contra Costa County, here are some options and resources available to you to be able to dispose of your batters properly.



ALERT: Department of Transportation (DOT) Law Regarding Battery Disposal

Many types of batteries MUST BE properly secured for disposal to prevent a possible spark. This will reduce the risk of fire during storage and transportation.

Please use clear tape over the positive terminal of the following batteries, or place them individually in clear plastic sealed bags:

  • Alkaline batteries that are 9-volts or greater, including AAA, AA, C, and D.
  • Lithium batteries: found in cameras, computers, watches (for small, circular batteries, tape around the entire battery).
  • NiCad, Zinc Chloride and rechargeable batteries (found in cellphones, power tools, toys).
