Properly disposing of batteries is important for both environmental and safety reasons. Here are some general guidelines for disposing of different types of batteries:

Alkaline Batteries (AA, AAA, etc.):
  • Alkaline batteries are non-hazardous and can usually be disposed of in your regular household trash.
  • However, it's a good idea to tape the terminals (the ends) of the battery with electrical or duct tape before disposal to prevent short circuits.
Rechargeable Batteries (NiMH, NiCd, Lithium-ion, etc.):
  • Rechargeable batteries contain heavy metals and other toxic materials, so they should not be thrown in the regular trash.
  • Many communities have special recycling programs or drop-off locations for rechargeable batteries. Check with your local recycling center or municipality for guidance on where to recycle them.
  • Some electronics stores or battery retailers also accept rechargeable batteries for recycling.
Button Cell Batteries:
  • Button cell batteries, commonly found in watches, calculators, and other small electronics, contain mercury or other hazardous materials.
  • They should be recycled rather than thrown in the trash.
  • Many retailers or electronics stores offer recycling programs for button cell batteries.
Car Batteries:
  • Car batteries contain lead and sulfuric acid, both of which are hazardous materials.
  • Many auto parts stores, service stations, or recycling centers will accept old car batteries
