Yes, Costco does take old car batteries—especially when you’re buying a new one from them.
They participate in battery recycling programs and typically charge a core fee when you purchase a new battery, which is refundable when you return your old (used) battery.

How It Works at Costco

✅ Core Charge Policy

• When you buy a new car battery at Costco, you’ll pay a core deposit (usually around $10–$15).
• When you bring back your old battery (also called the “core”), Costco refunds the core charge.

✅ Battery Recycling

• Costco sends the old batteries to certified recyclers, where they are safely processed, and materials are reused.
• This keeps lead and acid out of the environment.

Can You Return a Battery Without Buying One?

This varies by location, but generally:

• Costco accepts old batteries even if you didn’t buy the new one there—but they may not refund a core fee unless there’s a purchase record.
• If you’re just looking to dispose of a battery properly, it’s still worth bringing it in.

What You Should Bring

• The old battery (core)
• Your receipt, if you want the core charge refund
• Ideally, return it to the Tire or Automotive Center at your Costco location

Final Thoughts

Yes, Costco accepts old car batteries, especially when tied to a battery purchase. Returning your old battery gets you a core refund and helps ensure it’s recycled responsibly. If you’re unsure about your local store’s policy, you can always ask at the Tire Center for specific guidance.
