How much does a Subaru battery cost?
Typically a replacement Subaru 12-volt battery costs around $100 to $350, depending on the battery type and model, with additional charges for installation or disposal.
What determines the price
Battery type
Standard lead-acid, maintenance-free batteries are usually cheaper, while AGM (absorbent glass mat) batteries—which offer better cold-weather performance and longer life—tend to cost more.
Vehicle model and group size
Different Subaru models require different battery sizes and cold-cranking amps (CCA). The exact size and rating needed are shown on the current battery label or in the owner's manual, and they significantly influence price.
Brand, warranty, and retailer
OEM Subaru batteries (or OEM-equivalent AGM units) typically cost more but may come with longer warranties and guaranteed compatibility. Retailer specials, memberships, and installation deals also affect final pricing.
Typical price ranges
Prices vary by battery configuration; the ballpark ranges below reflect common options for Subaru owners in the U.S. and Canada.
- Standard maintenance-free lead-acid battery: roughly $100–$150
- AGM battery (preferred for newer Subarus and cold climates): roughly $180–$260
- OEM Subaru or premium aftermarket AGM: roughly $200–$350
- Installation or disposal fees when purchased from a shop: roughly $20–$100
Keep in mind that prices fluctuate by region and retailer, and some outlets include installation in the price or offer free installation with purchase.
Where to buy and what to expect
Where you buy a Subaru battery matters for price, warranty, and service. Common options include:
- Authorized Subaru dealers or service centers
- Auto parts chains (AutoZone, Advance Auto Parts, O'Reilly)
- Warehouse clubs and big-box retailers (Costco, Sam's Club, Walmart)
- Online retailers with local pickup or installation services
Dealer prices tend to be higher but may include installation help and more comprehensive warranties. Aftermarket retailers often offer lower prices with a range of warranty options.
Tips to ensure you buy the right battery
Before purchasing, verify the correct size, capacity, and warranty. Use these steps:
- Check your owner's manual or the current battery label to confirm the group size and CCA rating.
- Match the CCA and reserve capacity to your climate and driving needs.
- Choose a warranty length that fits your budget and peace of mind (3–4 years is common; longer is better for AGM).
- Ask about installation services and whether core charges are waived or credited.
Following these guidelines helps ensure compatibility and the best overall value.
Lifespan and maintenance considerations
Most Subaru batteries last about 3–5 years under typical use. Extreme temperatures, frequent short trips, or heavy electrical loads can shorten lifespan. Regular inspection and clean terminal connections can help maintain performance.
Summary
For most Subaru owners, planning for a replacement battery in the range of $100 to $350 covers standard lead-acid and AGM configurations, with installation and regional factors shaping the final price. Prioritize the correct size and CCA for your model, weigh OEM versus aftermarket options, and consider warranty length to maximize reliability and value over the vehicle’s lifetime.
