Proper handling of used batteries

Batteries used in many household and office products, as well as motor vehicle batteries, contain a variety of heavy metals and other materials that can be harmful to human health and the environment if not handled properly. Many of these materials can be recovered and reused by specialized recyclers.

Note that there are different requirements for batteries from households and batteries from businesses and other non-households. Many batteries, including lead-acid batteries, are regulated as universal (hazardous) waste when not generated by households. Visit Managing universal waste in Wisconsin for additional information on recycling/disposal requirements for non-households.

Dry cell batteries

Batteries used in homes, businesses and schools

Household AA batteries

Dry cell batteries are batteries used in many products – including portable electronics, power tools, watches, calculators, hand-held vacuum cleaners, lawn care equipment, flashlights, toys and hearing aids. They come in a variety of sizes and shapes and include both rechargeable and non-rechargeable battery types. They include alkaline, alkaline rechargeable, lithium, lithium-ion, metal hydride, mercuric oxide, nickel-cadmium, silver oxide and zinc-air batteries. They include AAA, AA, C, D, 9V, button, coin and other sizes, and may also be incorporated in products (such as cellphones and laptops).

Reduce waste by buying rechargeable batteries when possible. When rechargeable batteries come to the end of their lifespan, they can be recycled.

Alkaline batteries may be put in the trash, but some battery retailers or other recycling locations may accept alkaline batteries for a fee.

Environmental and safety impacts of dry cell batteries

The materials in many types of dry cell batteries – including mercury, lithium, cadmium, lead and acids – have the potential to be hazardous wastes. If these batteries are burned or landfilled, the heavy metals in them can be released into the environment.

Many batteries, particularly rechargeable lithium-ion batteries used in many electronics, present a significant risk of fire if they are mishandled or damaged. For that reason, it is important to handle used batteries properly.

Safe management of used batteries from households

Wisconsin has no legal requirements for the disposal of household-generated dry-cell batteries or for household-generated hazardous wastes. While households are not required to recycle batteries, putting non-alkaline batteries in the trash or curbside recycling carts/bins can pose a risk to garbage collectors, solid waste transfer stations and landfills because of the potential for the batteries to catch on fire, especially if damaged by equipment.

Many types of consumer electronics are banned from landfill or incinerator disposal in Wisconsin and can be recycled through the E-Cycle Wisconsin program. Homeowners should check with their local recycling program to see if there are additional restrictions.

The publication below includes a guide to managing different types of batteries.

If storing batteries for recycling, you can reduce fire risk by taping ends of batteries with clear packing tape or putting each battery in an individual plastic bag, and storing them in a non-metal leakproof container with a lid (such as a plastic bucket).

Requirements for managing batteries from non-households

Batteries generated by businesses, schools, institutions, governments and other non-households are subject to hazardous waste requirements, which allow for certain wastes to be managed under universal waste requirements. Alkaline batteries may be put in the trash, but others must be recycled or managed as universal waste. See the publications below for a guide to managing different battery types and a printable poster with collection and storage requirements and best management practices.

Find battery recycling locations

Do NOT place batteries or electronics in curbside recycling carts or bins, because they may cause a fire if damaged by equipment in recycling trucks or facilities.

Requirements and safety procedures for battery collectors, transporters and recyclers

Battery collectors, transporters and recyclers must follow universal and hazardous waste requirements and U.S. Department of Transportation regulations for used batteries from both households and businesses/non-households. There are also several best management practices designed to prevent fires.

Automotive (lead-acid) batteries

Batteries used in motor vehicles and engines

Lead-acid batteries, or "automotive type batteries," are found in cars, trucks, motorcycles, boats and vehicles and devices with internal combustion engines.

Car battery

Chapter 287.07(1m), Wis. Stats., bans lead-acid batteries from landfill disposal and incineration at a solid waste incinerator. They can be collected for recycling or regeneration under hazardous and universal waste rules.

Storage, transport, collection, recycling and regeneration of lead-acid batteries is regulated under ch. NR 673 or subch. G of ch. NR 666, Wis. Adm. Code.

Safe handling of lead-acid batteries

When handling a used lead-acid battery, use rubber gloves and eye protection and always wash hands immediately after handling the battery. Acid from leaking batteries can burn the eyes and skin.

Store used batteries in a cool, dry, well-ventilated area on a leak-proof surface or in a leak-proof container to protect against exposure and ensure that acid and lead will not leak into soil or groundwater. Do not short circuit battery terminals or remove vent caps. If stored improperly, lead-acid batteries may leak or spill and cause lead and/or acid contamination of the soil and groundwater. If the battery is cracked or leaking, store and/or transport it in a sealed five-gallon plastic pail. Take the battery directly to a retailer/recycler to avoid long-term storage damage and leakage.

Retailer battery recycling program

Consumers may bring lead-acid batteries to any Wisconsin retailer that sells these batteries, during normal business hours, for recycling. This service is free to customers who purchase a new battery when they bring in a used one. Customers may be charged a fee of up to $3 if they bring in a used battery without purchasing a new one.

Retailers must charge a deposit of $10 on the sale of an automotive type replacement battery and must refund the deposit if the customer returns to the same retailer, at any location owned or operated by the retailer, with a used battery. The retailer may require proof that the consumer purchased a battery from the retailer.

The state recycling law requires battery retailers to post a sign stating "Recycle Automotive Batteries Here." The sign must be 8.5 x 11 inches and be visible to customers.
