If you are having a difficult time finding out what to
do with used batteries and where you can take them to be recycled or
safely treated and disposed, then you should find a solution here on
this page. Whether you have a AAA, AA, C, D, watch, button, hearing aid
or car battery, there is a solution.
Use the links below to jump ahead to the summary table if you are not interested in the background information.
People are using more and more household batteries. The average person owns about two button batteries, ten normal (A, AA, AAA, C, D, 9V, etc.) batteries, and throws out about eight household batteries per year. About three billion batteries are sold annually in the U.S. averaging about 32 per family or ten per person. A battery is an electrochemical device with the ability to convert chemical energy to electrical energy to provide power to electronic devices. Batteries contain heavy metals such as mercury, lead, cadmium, and nickel, which can contaminate the environment when batteries are improperly disposed of. When incinerated, certain metals might be released into the air or can concentrate in the ash produced by the combustion process.
Batteries may produce the following potential problems or hazards:
In landfills, heavy metals have the potential to leach slowly into soil, groundwater or surface water. Dry cell batteries contribute about 88 percent of the total mercury and 50 percent of the cadmium in the municipal solid waste stream. In the past, batteries accounted for nearly half of the mercury used in the United States and over half of the mercury and cadmium in the municipal solid waste stream. When burned, some heavy metals such as mercury may vaporize and escape into the air, and cadmium and lead may end up in the ash.
This may change now that California has mandated recycling for "dry cell" batteries.
Many states have regulations in place requiring some form of battery recycling. California mandates recycling for almost all battery types.
The U.S. Congress passed the Mercury-Containing and Rechargeable Battery Management Act in 1996 to make it easier for rechargeable battery and product manufacturers to collect and recycle Ni-CD batteries and certain small sealed lead-acid batteries. For these regulated batteries, the act requires the following:
Nearly 90 percent of all lead-acid batteries are recycled. Almost any retailer that sells lead-acid batteries collects used batteries for recycling, as required by most state laws. Reclaimers crush batteries into nickel-sized pieces and separate the plastic components. They send the plastic to a reprocessor for manufacture into new plastic products and deliver purified lead to battery manufacturers and other industries. A typical lead-acid battery contains 60 to 80 percent recycled lead and plastic.
Gel cells and sealed lead-acid batteries are commonly used to power industrial equipment, emergency lighting, and alarm systems. The same recycling process applies as with automotive batteries. An automotive store or a local waste agency may accept the batteries for recycling.
Dry-cell batteries include alkaline and carbon zinc (9-volt, D, C, AA, AAA), mercuric-oxide (button, some cylindrical and rectangular), silver-oxide and zinc-air (button), and lithium (9-volt, C, AA, coin, button, rechargeable). On average, each person in the United States discards eight dry-cell batteries per year.
Primary batteries include alkaline/manganese, carbon-zinc, mercuric-oxide, zinc-air, silver-oxide, and other types of button batteries. Secondary batteries (rechargeable) include lead-acid, nickel-cadmium, and potentially nickel-hydrogen.
|Typical Types of Household Batteries|
|Alkaline*||Cassettes players, radios, appliances|
|Carbon-zinc||Flashlights, toys, etc.|
|Lithium||Cameras, calculators, watches, computers, etc.|
|Mercury||Hearing aids, pacemakers, cameras, calculators, watches, etc.|
|Silver||Hearing aids, watches, cameras, calculators|
|Zinc||Hearing aids, pagers|
|Nickel-cadmium||Cameras, rechargeable appliances such as portable power tools, hand held vacuums, etc.|
|Small sealed lead-acid||Camcorders, computers, portable radios and tape players, cellular phones, lawn mower starters, etc.|
|*Some rechargeable alkaline batteries are available, but they are pretty rare.|
Recycling and Disposal
Mercuric-oxide batteries are being gradually replaced by new technology such as silver-oxide and zinc-air button batteries that contain less mercury.
Nickel-cadmium rechargeable batteries are being researched. Alternatives such as cadmium free nickel and nickel-hydride system are being researched, but nickel-cadmium are unlikely to be totally replaced. Nickel-cadmium batteries can be reprocessed to reclaim the nickel. However, currently approximately 80 percent of all nickel-cadmium batteries are permanently sealed in appliances. Changing regulations may result in easier access to the nickel-cadmium batteries for recycling.
To reduce waste, start with prevention. Starting with prevention creates less or no leftover waste to become potentially hazardous waste. The following are steps to take to prevent household battery waste.
As of 2015, the state of California is the only state in where you must receyycle over-the-counter consumer alakaline batteries (AAA, AA, C, D, 9volt, etc.) . In California it is illegal to throw any type of battery (including disposable single-use batteries) in the trash. Proven cost-effective and environmentally safe recycling processes are not yet universally available for alkaline batteries. A few communities offer recycling or collection of alkaline batteries, contact your local government for disposal practices in your area.
Alkaline batteries can be safely disposed of with normal household waste, since the Mercury-Containing and Rechargeable Battery Management Act passed in 1996 that phased out the use of mercury in alkaline batteries. That means they aren't nearly so toxic when disposed in landfills. Alkaline batteries are composed primarily of common metals—steel, zinc, and manganese—that do not pose a health or environmental risk during normal use or disposal.
Here is the bottom line:
The use of rechargeable nickel-cadmium batteries can reduce the number of batteries entering the waste stream, but may increase the amount of heavy metals entering the waste stream unless they are more effectively recycled. As of 1992, the percentage of cadmium in nickel-cadmium batteries was higher than the percentage of mercury in alkaline batteries, so substitution might only replace one heavy metal for another, and rechargeable batteries do use energy resources in recharging.
Rechargeable alkaline batteries are available along with rechargers.
Recycling of non rechargeable batteries is becoming more commonplace, but it can still be a challenge to find a local drop-off location. Recycling used RECHARGEABLE household batteries is now possible! The battery manufacturers have funded a joint recycling center. To find a center near you that will take them, click here! (in the US or Canada))( Which types do they take? Nickel Cadmium (Ni-Cd), Nickel Metal Hydride (Ni-MH), Lithium Ion (Li-ion), and Small Sealed Lead* (Pb) rechargeable batteries are commonly found in cordless power tools, cellular and cordless phones, laptop computers, digital cameras, two-way radios, camcorders and remote control toys.
Note that California is a bit of a special case. California regulations require recycling for more types of batteries than other states. See this page for detailed information about how and where to recycle batteries in California.

Use the RBRC collection site locator, or call the consumer helpline, 1-800-8-BATTERY, to find the retail collection site nearest you.
Non-rechargeable (typically "alkaline batteries") still don't have a recycler and general just must be disposed in the trash. If you have large quantities or are a business, talk with your permitted sanitary landfill operator (otherwise known as "sanitation services", the "dump" or "landfill"). Waste batteries should not be burned because of the metals, and they could explode. When burned, some heavy metals such as mercury may vaporize and escape into the air, and cadmium and lead may end up in the ash.

|Contact your local or county health department, waste disposal operator, extension educator, recycling facility, call the EPA Hotline and ask for a copy of the publication: "Used Dry Cell Batteries" - phone (800) 424-9346. This publication does not address nonhousehold waste battery sources such as medical, business, etc.|
Check with your local solid waste management district (listed under County Government in your phone book) for any outlets for household battery recycling. See if your local jeweler, pharmacy or battery retailer will accept button batteries for recycling. Ohio EPA keeps a list of battery recycling and disposal companies on file; however, these companies are usually set up to serve industrial or municipal customers with bulk amounts of batteries rather than individuals.
