Background

Every year in the United States, millions of single use and rechargeable batteries are bought, used and recycled or disposed of in the trash. Batteries come in various chemistries, types and sizes to fit their use.

Single-use batteries can generally be removed from the device when they stop powering the device.
Rechargeable batteries may be removable or permanently attached to the device.

The increased demand for batteries can be traced largely to the rapid increase in use of small portable electronics, power tools, and other everyday items, as well as the increase in “smart” products, such as small and large appliances and automobiles.

Batteries are manufactured using different mixtures of chemical elements designed to meet customers’ power and performance needs. Batteries can contain metals such as mercury, lead, cadmium, nickel and silver, which can pose a threat to human health or the environment when improperly managed at the end of their service life. Battery types are identified by marking and labeling, not by the battery’s shape or the color of the label.

Some batteries may also contain materials such as cobalt, lithium and graphite that are considered critical minerals by the United States Geological Survey. Critical minerals are raw materials that are economically and strategically important to the United States and have a high supply risk potential and for which there are no easy substitutes. Consequently, every effort should be made to recycle and recover these materials to ensure they will be available for generations to come.

Once a battery is no longer useful, the type and chemistry of the battery determines which of the various waste management options to use. It is important to manage batteries correctly according to their type because some batteries can cause a risk to safety and health if mismanaged at the end of their lives. Batteries can have enough energy to injure or start fires even when used and when they appear to be discharged. For safety, remember that not all batteries are removable or serviceable by the user—heed battery and product markings regarding safety and use for all types of batteries.

Single-Use Batteries

TypeUses and DescriptionDisposal

Alkaline and Zinc-Carbon

These common everyday batteries can be used in products such as alarm clocks, calculators, flashlights, TV remote controls, radios, remote-control products, children’s toys and other items.
For example, some common alkaline and zinc-carbon batteries include 9 Volt, AA, AAA, C, D and some button cells.

Some reclamation companies recycle these batteries; check with your local or state solid waste authority for management options. In most communities, alkaline and zinc carbon batteries can be safely put in your household trash.

EPA recommendation: send used alkaline and zinc carbon batteries to battery recyclers or check with your local or state solid waste authority.

Button-Cell or Coin

These small, round batteries have historically contained silver, cadmium, mercury or other heavy metals as their main component.
Today, the majority are made of lithium metal. These batteries are commonly used in products such as watches, hearing aids, car keyless entry remotes, medical devices and calculators.

Button-cell or coin batteries can be a potential swallowing hazard; store them out of the reach of young children.

Management requirements are based on the battery’s chemistry. They can be brought to specialized battery recyclers, participating retailers that provide battery takeback services or local household hazardous waste collection programs. Contact the manufacturer or local solid waste authority for additional management options.

Handling precautions: Place each battery in separate plastic bags or place non-conductive tape (e.g., electrical tape) over the battery’s terminals or around the entire button. A lithium battery may spark and cause fires if damaged or the terminal ends touch. If the battery becomes damaged, contact the manufacturer for specific handling information.

EPA recommendation: Check for the word “lithium” marked on the battery. Do not put button-cell, coin, or lithium single use batteries in the trash or municipal recycling bins. Find a recycling location near you:

Lithium Single-Use

These common batteries are made with lithium (Li) metal and are single-use and non-rechargeable
They are used in products such as cameras, watches, remote controls, handheld games and smoke detectors.
These batteries may be difficult to distinguish from common alkaline batteries, but may also have specialized shapes for specific equipment, such as some types of cameras and calculators.

Rechargeable Batteries
