Not Rechargeable

Alkaline Batteries

Common household batteries are also called alkaline batteries; the chemical type is important in choosing proper disposal options.

While “regular” batteries - AA, AAA, C, D, 9-volt - contained high levels of mercury until approximately 1997, today’s contain just trace elements of toxins. They are no longer considered a threat to properly equipped modern landfills. Dispose of standard alkaline batteries in the regular trash.

Rechargeable Lithium batteries are considered Household Hazardous Waste and must be disposed of accordingly.

9-Volt Batteries

When disposing of 9-volt batteries, always tape over the terminals with masking, duct, or electrical tape. Because both terminals are on the same end of the battery, even a “dead” 9-volt has enough power to spark a fire!

After the positive and negative posts are securely taped, 9-volt batteries can be disposed of in your regular trash. Read more about 9-volt battery safety (PDF).
