How much is a new battery for a Subaru?

Prices for a new Subaru 12-volt battery typically range from about $100 to $350, depending on battery type, model/year, and where you buy; installation can add about $50 to $100.


What affects the price


Several factors influence the final price you’ll pay for a new Subaru battery.



  • Battery type: standard lead-acid versus AGM (absorbent glass mat) batteries; AGM tends to cost more but offers longer life and better performance in cold weather, which Subarus benefit from.

  • Brand and warranty: OEM Subaru batteries tend to be pricier but may come with longer or more comprehensive warranties; aftermarket brands can be cheaper with similar warranty terms.

  • Vehicle model and year: newer models and wagons with more electrical systems may require higher-capacity batteries or different group sizes.

  • Retail channel: dealership, auto parts stores, or online retailers can price-shop differently, and installation costs vary.

  • Core charge and recycling: many retailers charge a core deposit that’s refunded when you return the old battery.


Understanding these factors helps you compare quotes and avoid surprises when replacing the battery.


Typical price ranges by battery type


Here is a general guide for Subaru owners choosing between common battery options.



  • Standard 12-volt lead-acid battery: about $100–$180.

  • AGM battery (common in newer Subarus): about $170–$280.

  • Premium or specialty batteries (high-output AGM or lithium options): typically $230–$350+, though lithium options are less common and can be considerably more expensive.


Note that Subaru dealership OEM batteries usually sit toward the higher end of these ranges, with installation and core charges affecting the total.


Where to buy and installation costs


Options for purchasing and what to expect for installation costs.



  • Dealership: OEM battery, exact fit, and service options; prices commonly in the higher range, roughly $180–$320, with installation often available for an added fee.

  • Auto parts stores and big-box retailers: wide range of aftermarket AGM and standard batteries; typical price range $120–$260; core charges often $5–$20; many offer free installation promotions.

  • Online retailers and installers: competitive pricing; installation can be arranged locally; verify warranty coverage and compatibility before buying.


When replacing the battery, check the warranty length and whether the installation is included or sold separately, and be mindful of the recycling or core-return requirements.


Tips to get the best value


To maximize reliability and value, consider these practical tips.



  • Know your Subaru’s battery group size and required CCA (cold-cranking amps) and reserve capacity, which you can find in the owner’s manual or by checking the existing battery label.

  • Prefer AGM if you live in cold climates or use many electrical accessories, as Subarus often benefit from AGM performance and longer life.

  • Compare warranties: look for at least 3-4 years of coverage; some brands offer longer warranties.


By planning ahead, you can reduce the risk of a premature battery failure and get a price that fits your needs.


Summary


In short, replacing a Subaru battery typically costs between $100 and $350, depending on the battery type, brand, and where you buy. Expect additional costs for installation and possible core charges. Always verify compatibility with your model and check warranty terms to maximize value and reliability.

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 do Subaru batteries last?


Subaru batteries typically last between 3 to 5 years, but this can vary depending on factors like climate, driving habits, and the type of battery. To maximize lifespan, it is important to have your battery regularly inspected and to be aware of signs of a failing battery, such as slow electrical functions or a rotten egg smell.
 
Factors that influence battery life

  • Climate: Extreme heat and cold can both shorten a battery's life. Hot weather can cause fluid evaporation, while cold weather makes batteries work harder. 
  • Driving habits: Frequent short trips limit the time for the alternator to fully recharge the battery, which can lead to premature depletion. 
  • Electrical load: Modern cars with advanced electronics, like driver-assist systems and heated seats, place greater demand on the battery. 
  • Battery condition: A battery that is not tightly fastened can be damaged by vibrations. 

Signs of a failing battery
  • Slow or malfunctioning electrical components (like lights) 
  • A strange or "rotten egg" smell coming from the battery 
  • A build-up of corrosion (an ash-like substance) on the battery terminals 
  • The battery fails to start the car, often with a clicking sound 

How to extend battery life
  • Have your battery inspected at every service visit. 
  • Ensure the battery is securely fastened to prevent vibration damage. 
  • Consider replacing your battery every 3 to 4 years as a preventative measure, even if it seems to be working fine. 



Will Subaru replace my battery for free?


Yes, Subaru will replace your battery for free if it is under the standard warranty (3 years/36,000 miles) or if it qualifies under a specific battery settlement program. A separate warranty for genuine Subaru replacement batteries offers free replacement for 30 months, followed by a prorated warranty for 85 months. 
Under the standard new vehicle warranty

  • Duration: The original equipment battery is covered for three years or 36,000 miles, whichever comes first.
  • Coverage: If the battery fails within this period due to a defect, the dealer should replace it for free. 

Under the Genuine Subaru Battery warranty
  • Free replacement: If you install a Genuine Subaru Replacement Battery, you get a 30-month free replacement warranty, including labor and, in some cases, towing. 
  • Prorated coverage: After the initial 30-month free period, the battery may have prorated warranty coverage for up to 85 months. 

Under the Subaru battery settlement
  • Eligibility: You may be entitled to an extended warranty if your vehicle is part of the settlement class and the battery failed within the last six months. 
  • Extended coverage: This settlement provides extended warranty service for qualifying battery failures, which may include extended coverage for certain drain-related issues. 

Important considerations
  • Dealer inspection: It is recommended to take your vehicle to a dealer to determine the root cause of the issue and see if it is covered under any of these programs. 
  • DIY replacements: If you replaced the battery yourself, the warranty may not apply. It's best to use a Genuine Subaru battery or have a dealer replace it to ensure warranty coverage.
