Battery Recycling
Lead-Acid Automobile Batteries
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.
Non-Automotive Lead-Based Batteries
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
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.
- Alkaline and Zinc-Carbon Batteries
Alkaline batteries, the everyday household batteries used in flashlights, remote controls, and other appliances. Several reclamation companies now process these batteries. - Button-Cell Batteries
Most small, round “button-cell” type batteries found in items such as watches and hearing aids contain mercury, silver, cadmium, lithium, or other heavy metals as their main component. Button cells are increasingly targeted for recycling because of the value of recoverable materials, their small size, and their easy handling relative to other battery types. - Rechargeable Batteries
The Rechargeable Battery Recycling Corporation (RBRC), a nonprofit public service organization, targets four kinds of rechargeable batteries for recycling: nickel-cadmium (Ni-CD), nickel metal hydride, lithium ion, and small-sealed lead. Its “Charge Up to Recycle!” program offers various recycling plans for communities, retailers, businesses, and public agencies.
