You should never throw an old car battery in the regular trash. The safest and most common way to dispose of it is to take it back to where you bought it. Most automotive retailers, like AutoZone, Advance Auto Parts, or O'Reilly Auto Parts, are legally required to accept your old battery when you purchase a new one, and many will take it for recycling even if you aren't buying one. Other excellent options include local household hazardous waste (HHW) collection facilities or authorized scrapyards.
Car batteries are classified as hazardous waste because they contain sulfuric acid and lead. Both are highly toxic and can contaminate soil and groundwater if sent to a landfill. Proper recycling is crucial—over 99% of a typical lead-acid battery can be recycled into new products.
Here’s a quick guide to your disposal options:
| Disposal Location | Typical Cost | Key Requirement / Note |
|---|
| Auto Parts Store (e.g., AutoZone) | Free (often with a core charge refund) | Most accept up to 2-3 batteries per day without a purchase. |
| Big-Box Retailer (e.g., Walmart Auto Care Center) | Free | Usually requires the purchase of a new battery. |
| Local Government Hazardous Waste Facility | Free or small fee | May require scheduling an appointment; best for other hazardous materials too. |
| Scrap Metal Yard / Recycling Center | May pay you a small amount | Prices fluctuate based on lead commodity markets. |
| Car Battery Manufacturer | Free | Some have specific mail-in or drop-off recycling programs. |
Before you go, handle the battery safely. Wear gloves and safety glasses, and place the battery in a sturdy plastic container to prevent tipping and acid leaks. Transport it in your trunk or the bed of a truck, not the passenger cabin. If you're unsure of the closest location, a quick online search for "car battery recycling near me" will provide the most up-to-date options.
