Car batteries are the silent heroes of every vehicle — they start the engine, power lights, and keep electronics running smoothly. But when the battery weakens, you’ll quickly feel the difference. This guide explains how much a car battery costs, and how to replace your car battery, and what factors affect the price — so you can make a smart, budget-friendly decision.
How Much Is a Car Battery?
The average car battery price ranges from $70 to $250, depending on the type, brand, and size of your vehicle.
- Standard lead-acid batteries (used in most cars) cost around $70–$120.
- AGM (Absorbent Glass Mat) batteries, known for better performance and durability, typically cost $150–$250.
- Electric or hybrid vehicle batteries can range from $1,000 to over $6,000, depending on make and model.
When buying, always check your car’s manual to confirm the right group size and specifications before purchase.
How Much Does It Cost to Replace a Car Battery?
The total cost to replace a car battery includes both the price of the battery and installation service. On average, expect to pay:
- DIY replacement: $80–$200 (you buy and install it yourself).
- Professional replacement: $150–$350 (includes labor and battery).
Luxury cars, hybrid systems, and vehicles with tight engine compartments may cost more due to extra labor or special battery types.
Does Costco Install Car Batteries
Costco sells car batteries, primarily the popular Interstate brand, at competitive prices. However, Costco does not install car batteries at most locations.
They provide battery testing and exchange services but you’ll need to visit a mechanic, auto shop, or service center for installation.
If you prefer both purchase and installation in one place, stores like AutoZone, Advance Auto Parts, or Pep Boys offer this service.
How to Replace a Car Battery
Replacing a car battery is simple if done safely. Here’s how to do it yourself:
- Turn off the engine and put the car in park with the parking brake on.
- Locate the battery, usually under the hood or sometimes in the trunk.
- Disconnect the negative cable (black) first, then the positive (red).
- Remove the old battery and clean any corrosion from the terminals.
- Insert the new battery and reconnect cables — positive first, then negative.
- Tighten the clamps and ensure the battery is secure before starting the car.
Tip: Always wear safety gloves and goggles to protect yourself from acid or sparks.
Where to Buy Car Batteries Online or In-Store

Factors That Affect Car Battery Price
Several factors influence the cost of a new battery:
- Type & Technology: AGM and EFB batteries are more expensive than standard ones.
- Brand & Warranty: Premium brands offer longer warranties (up to 5 years).
- Vehicle Type: Trucks, SUVs, and electric vehicles require higher capacity batteries.
- Cold Cranking Amps (CCA): A higher CCA rating provides better starting power in cold weather, increasing the price.
- Eco Fees & Core Charges: Some stores charge refundable fees for old battery recycling.
Understanding these factors helps you balance performance with budget.
