A used car battery is not ordinary trash. Most contain lead and acid, which can harm people and the environment if they end up in a landfill. The good news is that car batteries are widely recycled, and getting rid of one is usually easy.
Never put it in the trash or curbside bin
Car batteries are generally classified as hazardous waste, and in many places it is illegal to throw them away with household garbage. Rules vary by location, so check with your local waste authority if you are unsure. Also avoid leaving one in the garage or yard, where it can leak.
Where to take an old car battery
- Auto parts stores and battery retailers. Many accept used batteries, often whether or not you bought the new one from them. Policies differ, so call ahead.
- Repair shops and dealerships. If a shop replaces your battery, they normally take the old one.
- Recycling centers and scrap yards. Many accept lead-acid batteries.
- Household hazardous waste sites. Many local governments run collection days or drop-off points.
- Large retailers. Some home improvement and general retailers take batteries, but it differs by store and country. Check your nearest branch first.
Core charges and trade-ins
When you buy a new battery, you may pay a refundable deposit called a core charge, which is returned when you bring in an old one. If you swap at home, keep your receipt and bring the old battery back to the seller to get the deposit refunded, if there is one. Terms vary.
Prepare and transport it safely
- Wear gloves and eye protection when handling it.
- Keep the battery upright. Do not tip it.
- Place it in a sturdy plastic tub, box or battery tray so any leak is contained.
- Secure it in the trunk or truck bed so it cannot slide.
- Take it directly to the drop-off point and do not stack heavy items on top.

What if it is leaking or damaged?
Handle it with gloves and eye protection, keep it upright in a leak-proof container, and avoid touching the fluid. Call the recycler or your local hazardous waste program before you go, because they may have specific instructions. Do not pour the liquid on the ground or down a drain.
What happens during recycling
Lead-acid batteries are typically broken apart, and the lead, plastic and acid are separated and processed. The lead and plastic can be reused to make new batteries, which is why recycling is such a common route for these batteries.
