Does Costco Install Car Batteries? (Prices & Where to Get It Done)
Costco does not install car batteries — their Tire and Battery Center sells Interstate brand batteries only, with no installation service. Skipping this detail could leave you stuck with a new battery and no one to put it in. AutoZone installs batteries free with any purchase; Walmart charges $10–$25. This guide covers Costco’s Interstate battery prices ($90–$180), their 36-month warranty, and exactly where to get a Costco battery installed.
Quick Answer
Costco does not install car batteries. They sell Interstate brand standard and AGM batteries ($90–$180) at their Tire and Battery Center with a 36-month warranty. To get your Costco battery installed, take it to AutoZone (free with their battery purchase) or Walmart Auto Care ($10–$25).
Does Costco Sell Car Batteries?
Interstate Battery is a leading U.S. automotive battery brand sold exclusively at Costco’s Tire and Battery Center — available in standard flooded and AGM configurations for most cars, trucks, SUVs, and recreational vehicles. Costco does not carry any other battery brands.
- Standard Flooded Battery: Best for most everyday vehicles. Group 35 example: ~$110, 640 CCA, 800 CA.
- AGM (Absorbed Glass Mat) Battery: Required for vehicles with start-stop technology, push-button ignition, or heavy electronics. Group 35 AGM: ~$180, 650 CCA, 800 CA.
To find the right battery, use Costco’s online battery finder or ask an employee at the Tire Center. Batteries are warehouse-only — no online ordering for home delivery. You can also learn which terminal to connect first before installation.
Does Costco Install Car Batteries?
No — Costco does not install car batteries. Their Tire and Battery Center sells batteries and handles tire services, but battery installation is not offered at any Costco location. This applies whether you are buying a new battery or bringing one in from another retailer.
Why Doesn’t Costco Offer Battery Installation?
Costco’s business model focuses on high-volume, low-margin product sales. Offering installation would require certified technicians, expanded liability coverage, and longer service appointments — all of which raise costs. Their tire installation is a separate, insured operation integrated into the warehouse layout. Battery installation has never been part of that model.
How Much Do Costco Car Batteries Cost?
Costco Interstate batteries typically cost $90–$180 depending on group size and type, plus a $10–$15 core charge refunded when you return your old battery. Compared to the same Interstate batteries at O’Reilly ($180–$230) or AutoZone ($150–$210), Costco members save $30–$60 on average.

|---|---|---|---|
| Standard Flooded | ~$90–$120 | 640 CCA | Most everyday vehicles |

A Costco membership ($65/year for Gold Star) is required. Non-members cannot buy batteries at Costco.

How to Install a Car Battery Yourself
Installing a car battery takes 20–30 minutes and requires only a wrench and gloves. Always disconnect the negative (black) cable first and reconnect it last.
- Turn off the vehicle and remove the keys from the ignition.
- Locate the battery — usually under the hood, sometimes in the trunk or under a seat.
- Disconnect the negative cable (black, marked –) first, then the positive cable (red, marked +).
- Remove any hold-down clamp and lift out the old battery. Batteries weigh 30–50 lbs — lift carefully.
- Clean the battery terminals with a wire brush and baking soda solution to remove corrosion.
- Place the new battery in the tray and secure the hold-down clamp.
- Reconnect the positive cable (red) first, then the negative cable (black).
- Start the vehicle to confirm it works. Return the old battery to Costco for the core charge refund.

Costco’s Battery Warranty and Return Policy
All Costco Interstate batteries carry a 36-month limited warranty serviced through your local Costco warehouse — no receipt required, as purchases are tracked by membership account. The warranty covers defects in materials and workmanship; it does not cover damage from improper installation, deep discharge, or physical damage.
Both standard and AGM batteries carry the same 36-month coverage. If your battery fails within the warranty period, Costco replaces it at no charge. There is no prorated extension after 36 months.
How to Choose the Right Battery at Costco
Check your owner’s manual for the required group size (e.g., Group 35, Group 51R) and minimum Cold Cranking Amps (CCA). CCA measures how many amps a battery delivers at 0°F for 30 seconds — higher CCA matters most in cold climates. If your vehicle has start-stop technology, push-button ignition, or significant aftermarket electronics, choose AGM over standard flooded.
Costco’s Tire Center staff can confirm the correct battery for your vehicle’s make, model, and year.
