A Subaru WRX battery usually costs between about $100 and $350, depending on the battery type and where you buy it. Dealer-supplied OEM/AGM batteries tend to be in the $250–$350 range, aftermarket AGM batteries typically run $150–$250, and standard flooded lead-acid batteries are often $100–$180. If you hire a professional to install it, a shop may add labor fees on top of the battery price.
The following analysis breaks down what drives those price ranges, where to shop, and practical tips for choosing and replacing a WRX battery. Prices can vary by year, region, and retailer, so use these figures as a general guide and verify current quotes before purchasing.
Battery options and price ranges
Prices vary by battery type, brand, and retailer. The list below gives typical price bands you’re likely to encounter when shopping for a WRX battery.
Common WRX battery types
Most recent WRX models use a 12-volt battery, often an absorbed glass mat (AGM) type for better durability and longer life. Some older or lower-spec trims may still use flooded lead-acid batteries. Your exact price will depend on the exact group size and technology required for your car.
- OEM Subaru replacement AGM battery (from a dealer): typically $250–$350
- Aftermarket AGM battery (brand-name such as Interstate, DieHard, Duralast, etc.): typically $150–$250
- Flooded lead-acid battery (non-AGM) from aftermarket: typically $100–$180
- Premium/high-capacity AGM or specialty batteries: typically $280–$350
Prices are indicative and can fluctuate with promotions, location, and year of the WRX. Always confirm the exact group size and warranty when comparing options.
Where to buy and how price varies by retailer
Shopping channels influence price, core charges, and warranty options. The following range reflects typical offerings across common retailers.
- Subaru dealership (OEM): usually $250–$350, with potential installation options
- Auto parts chains (AutoZone, Advance Auto Parts, O'Reilly): often $120–$240 for aftermarket AGM or flooded batteries, with possible core charges
- Online retailers (Amazon, RockAuto, BatteryPros): commonly $100–$230, depending on brand and shipping; watch for core charges and return policies
- Battery specialty shops: typically $150–$260, sometimes with extended warranties
- Warehouse clubs/large retailers (e.g., Costco): often around $150–$230, sometimes with limited brands
Note that many retailers apply a core charge (a refundable deposit) when you return a old battery. Promotions, shipping costs, and install offers can change the final price, so it pays to shop around and ask about current deals.
Installation and maintenance considerations
Whether you install the battery yourself or have a shop do it, there are best practices that affect total cost and performance. The following steps outline a typical DIY replacement and what to expect if you hire a pro.
- Gather basic safety gear and tools: gloves, eye protection, wrenches, and battery terminal cleaner if available.
- Turn off the engine and remove the key, then locate the battery and disconnect the negative (-) terminal first, followed by the positive (+).
- Remove the hold-down bracket or tray, then lift the old battery out of the tray.
- Clean the battery tray and connectors; inspect for corrosion and replace any damaged cables if needed.
- Place the new battery in the tray, secure the hold-down, and connect the positive terminal first, then the negative terminal.
- Reset or reprogram any electronics if required by your model (radio codes, TPMS, etc.), and test the electrical system to ensure proper startup and charging.
- Dispose of the old battery at a proper recycling facility or return to the retailer for recycling; many places offer a core return or recycling credit.
Labor costs for professional installation vary by shop and region, but expect a modest service charge in addition to the battery price if you don’t DIY.
Summary
For a Subaru WRX, anticipate a total outlay in the approximate range of $100 to $350 for a new battery, depending on whether you choose a flooded or AGM design and whether you buy from a dealer, a big-box retailer, or an online seller. OEM/AGM batteries purchased from a dealer tend to be toward the higher end, while aftermarket AGM or flooded options from auto parts stores or online retailers offer broader price flexibility. Always verify the correct battery group size and check for core charges, warranties, and installation options to determine your true total cost.
