Household Batteries- Alkaline batteries are not accepted at the DPW or as Hazardous Household Waste. 

These batteries go in the trash.

Alkaline Batteries (AAA, AA, C, D, & 9 Volts) 

Batteries currently manufactured in the United States, AAA, AA, C, D, and 9-volt, contain no mercury and can be put in the trash. These batteries are not accepted at the DPW for recycling. Since 1994, most types contain no added mercury and contain only trace amounts. 

Automotive Batteries

Automotive batteries contain sulfuric acid that can burn skin. Do not throw them in the trash. Automotive batteries are banned from landfills and combustion facilities in Massachusetts. Most automotive battery retailers will accept your used battery for recycling when you purchase a new one. Many service stations, repair shops, salvage businesses, and scrap yards accept batteries, provided they are not broken or leaking. Use an online search engine such as Google or Bing to find nearby locations. Most community recycling centers and municipal household hazardous waste collection events accept automotive batteries. Handle batteries with acid-resistant or leather gloves. Keep sparks and flames away from batteries and don't smoke nearby. Never place metal objects on top of the battery because it can cause sparks. Remove rings, chains, and other metallic items before handling. Keep batteries right side up. Carry in a non-metallic, leak-proof container. If the battery leaks, neutralize any spilled acid with baking soda or calcium carbonate (lime). Flush the area with water. If acid comes in contact with the skin, flush the area with water immediately and seek medical attention if the burning continues.

Hazardous Waste Batteries

Rechargeable Batteries (Li-Ion, Ni-Cd, Ni-MH, Ni-ZN, & SSLA/Pb)

These are sold in many sizes and shapes and are marked "rechargeable." Some may be built into small appliances. These batteries generally contain metals that pose risks to human health and the environment. These batteries do not go in the trash. When storing rechargeable batteries for collection, keep them in a vented, non-metal container. Place these batteries in plastic bags before storing them with other rechargeables. Take these to a retail collection location or a municipal recycling center that accepts rechargeable batteries. There are more than 400 collection sites in Massachusetts that are free to residents. Search Call2Recycle for the nearest location.

Button Batteries (Small, Round, Silver-Colored, Used in Watches and Hearing Aids)

Many button batteries contain mercury, a metal that is toxic to humans when inhaled or ingested. Do not put them in the trash. Many stores selling watches or hearing aids will accept spent button batteries. If your trash is handled by a waste-to-energy facility, find out if they have a mercury waste collection program, or keep them aside for a local household hazardous waste collection day.

Lithium Batteries (AA, C, 9 Volts, & Button; Mainly Used in Computers, Phones, & Cameras)

Lithium is reactive with water and has caused serious fires. These batteries do not go in the trash. Hold for a local household hazardous waste collection day.

Improper disposal of batteries in landfills and batteries burned in waste combustion facilities can release mercury or cadmium into the air and water. These metals can enter the food chain and pose health threats to people and the environment.
