How much does a full car battery cost?
The typical replacement price for a standard 12‑volt car battery is around $80 to $200, with premium AGM or branded units often $150 to $350, plus possible installation and core charges.
What you're buying and why prices vary
In most vehicles, the “full battery” refers to the 12‑volt lead‑acid battery that starts the engine and powers accessories. Prices fluctuate based on the battery’s size (group size), chemistry (flooded vs. sealed AGM, and any specialty chemistries), and the brand. Higher‑performance or longer‑lasting options tend to cost more, while basic units are cheaper.
Price ranges by battery type
Prices vary by battery chemistry, size, and performance rating. Here are common options and typical price ranges you’ll see at retailers and service shops.
- Conventional flooded lead‑acid (standard, maintenance‑free units): 50–120 USD
- Sealed maintenance‑free / AGM batteries (higher reliability and power): 120–300 USD
- Premium or brand‑name AGM or high‑CCA units (longer warranty, more power): 180–350 USD
- Specialty or lithium‑based 12V batteries (less common; used in some hybrids and certain cars): 200–650 USD
Note: A core charge (typically about 10–25 USD) is often added at purchase and refunded when you return your old battery. Installation charges may also apply if you’re not buying the battery with a service install.
Prices vary widely by retailer, region, and exact vehicle model. Always verify the correct group size and warranty before purchasing, and factor in any core charge or potential installation fees.
What affects the price
Several factors determine the final price you see at the counter.
- Battery group size (the physical fit required for your vehicle) and desired power (CCA) and capacity (RC)
- Battery chemistry and technology (flooded vs AGM vs lithium, and any hybrid‑specific options)
- Brand, warranty length, and coverage terms
- Retail channel (auto parts store, dealership, online retailer) and any promotions
- Core charge and disposal fees
- Installation services or at‑home delivery options
- Vehicle requirements (start‑stop systems or higher power demands can drive up price)
- Geographic region and seasonal demand (winter shortages can raise prices briefly)
- New versus remanufactured or refurbished options
Bottom line: the right fit for your car, backed by a solid warranty, often matters more than the sticker price alone.
Costs for electric vehicles (EVs) and related notes
For electric vehicles, there are two batteries to consider: the 12‑volt auxiliary battery and the high‑voltage traction battery. Replacing the 12‑volt battery in an EV is similar to conventional cars and tends to cost in the hundreds of dollars, though OEM replacements for the high‑voltage pack are far more expensive. A new traction battery pack can range from roughly 5,000 to 15,000 USD or more, depending on the model, capacity (kWh), and whether the pack is new or refurbished. Warranty terms vary by manufacturer, and some packs are covered for many years or miles.
Tips to save money when replacing a car battery
Before you buy, consider these strategies to manage costs without compromising reliability.
- Shop around and compare prices across auto parts stores, big‑box retailers, independent shops, and dealerships
- Confirm the correct group size and vehicle compatibility before purchase
- Check the warranty length and what it covers (free replacement vs. pro‑rated)
- Ask about core charges and whether they’re refundable when you return the old battery
- Look for installation included in the price or offered as a low‑cost option
- Take advantage of seasonal promotions, coupons, or membership discounts
- Consider reputable aftermarket brands that meet OEM specifications
- Ask for a diagnostic test to confirm the battery is the problem before replacing it
- Ensure proper disposal of the old battery and confirm recycling options
With careful shopping and the right fit, most buyers can secure a reliable replacement at a reasonable price while still benefiting from warranty protection.
Summary
For most petrol‑powered cars, a new 12‑volt battery typically costs about $80 to $200, with AGM or premium models often $150 to $350 plus possible installation and core charges. Costs vary by size, chemistry, and brand, and installation charges can add to the total. In EVs, the 12‑volt battery is relatively affordable, but replacing the high‑voltage traction battery is a major expense that can run into the thousands. Shop around, verify compatibility, and consider warranty and installation options to get the best value.
What is the average cost to replace a car battery?
The average cost to replace a car battery is between $200 and $500, though the final price depends on the battery's cost (typically $75 to $250) and labor costs, which can range from $0 to over $100 depending on the vehicle and service provider. Factors like your car's make and model, the battery's specifications, and your geographic location influence the total price.
Cost breakdown
- Battery: Expect to pay between $75 and $250 for the battery itself, depending on its size, quality, and the vehicle it's for.
- Labor:
- Some auto parts stores and service centers offer free installation.
- Other labor costs can range from around $35 to over $150, depending on how difficult the battery is to access in your specific car.
- Total: The total can range from about $100 to over $500, with a common average falling in the $200-$500 range.
Factors that affect the cost
- Vehicle make and model: Luxury vehicles or hybrids may require more specialized and expensive batteries.
- Battery specifications: Higher-capacity or specialized batteries will cost more.
- Labor: The time it takes to replace the battery is a major factor. Batteries in some cars can be in difficult-to-access locations, increasing labor costs.
- Location: Costs can vary based on your geographic location due to transportation and local labor rates.
Is $300 too much for a car battery?
Overall you can expect to pay somewhere between $100 and $300 on average for a brand-new battery to last you a few years.

How long will a full car battery last?
A fully charged car battery can hold a charge for anywhere from a few weeks to a couple of months if the car is not used, but this depends heavily on its age and condition. A brand new battery in good condition can last about two weeks without driving, while a car with modern electronics or an older battery may lose its charge much faster. Factors like temperature, age, and any "parasitic draws" from onboard electronics or accessories all play a significant role in how long the charge lasts.
Factors that affect how long a battery lasts
- Battery age and condition: An older battery will lose its charge faster and is more susceptible to failure.
- Parasitic drain: Modern cars have constant, small power draws from their computers and security systems. This is called a parasitic drain and it will slowly discharge the battery over time.
- Extreme temperatures: Both extreme heat and cold can accelerate the rate at which a battery self-discharges.
- Short trips: Frequent short trips don't allow the alternator enough time to fully recharge the battery, leading to a gradual drain over time.
How to extend the life of your battery
- Drive regularly: Aim to drive your car for at least 30 minutes a week to ensure the battery gets a full charge.
- Use a trickle charger: If your car is parked for an extended period, a battery maintenance or trickle charger can keep it topped up.
- Check for parasitic drains: If your battery dies frequently, have an auto parts store test it for health and check for any unusual power drains.
- Maintain optimal storage conditions: If storing a vehicle for a long time, keep the battery in a cool, dry place with a consistent temperature between 404040 and 606060 degrees Fahrenheit, and consider disconnecting the negative battery cable.
