How much does a new battery for a Subaru Forester cost?
A new Subaru Forester battery usually costs about $150 to $300 for the battery itself, with installed prices typically ranging from $200 to $500 depending on battery type and labor.
The price varies by model year, battery group size, and whether you choose a standard flooded lead-acid battery or an upgraded AGM battery. It also depends on where you buy it and whether you install it yourself or have it installed by a shop. Below we break down the factors and current price ranges to help you budget.
What determines the price
Prices are shaped by several factors, including battery type, group size, brand, and installation method.
- Battery type: flooded lead-acid versus AGM. AGM batteries are more expensive but are often required for newer Forester models or vehicles with start-stop systems.
- Battery group size: Forester batteries come in specific group sizes (such as 35/35R or 24F, depending on year and trim); using the correct size is essential for fit and performance.
- Brand and retailer: OEM (dealer) batteries tend to cost more but may come with broader warranties; aftermarket brands at auto parts stores are typically cheaper but vary in warranty and performance.
- Warranty and service options: longer or more comprehensive warranties add value but raise upfront cost.
- Installation method: DIY only requires the battery; professional installation adds labor charges and may include disposal fees or battery recycling.
- Core charge and recycling: many retailers apply a core deposit (often $5–$20) refunded when you return the old battery.
All of these factors interact to set the final price, so it’s worth shopping around and asking for quotes that include the core charge and any disposal fees.
Typical price ranges
Across the United States as of 2025, here are ballpark ranges you can expect. Prices vary by location, retailer, and whether you choose a conventional or AGM battery.
- Conventional flooded lead-acid battery: roughly $90–$180
- Upgraded AGM battery: roughly $160–$300
- OEM Subaru battery from a dealer: typically around $170–$260
- Installed cost (DIY): battery price only
- Installed cost (professional): labor typically adds about $60–$150, depending on shop and locale
Some promotions or regional pricing can shift these ranges by $20–$50, so it pays to compare several sources and check for promotions or loyalty discounts.
Where to buy and how to save
Options include Subaru dealerships, national auto parts retailers (such as AutoZone, Advance Auto Parts, and O'Reilly), and online retailers. Here are tips to save on a Forester battery purchase:
- Shop around and obtain quotes from at least three sources, including installation costs.
- Choose AGM only if your Forester requires it or if you want longer life in cold climates; it costs more upfront but can be worth it over time.
- Look for promotions, price matching, and loyalty programs; combine with a battery installed to maximize value.
- Ask about the core charge and ensure you receive full credit for returning the old battery.
- Verify the correct group size and terminal orientation for your exact model year and trim to avoid fitment issues and warranty problems.
With careful shopping and a clear understanding of your Forester’s needs, you can secure reliable starting power at a sensible price.
Summary
For most Subaru Forester owners, budgeting $150–$300 for the battery itself and $200–$500 for installed cost is a reasonable expectation, with higher end figures tied to AGM batteries, dealership pricing, and labor charges. Always confirm the correct battery group size, consider whether AGM is necessary for your model, and compare quotes to lock in the best overall price and warranty coverage.
