Replacing the 12-volt battery in a Honda Accord Sport typically costs between $100 and $250 for the battery itself, depending on brand and type; installation and service fees can add to the total.
What determines the price
The cost of a replacement battery hinges on factors such as the battery type (standard flooded vs AGM), whether you buy an OEM Honda battery or an aftermarket equivalent, the retailer, your location, and whether professional installation is included. Labor charges are common if you have a shop install it, and some sellers apply a core charge when you return an old battery.
Battery types and price ranges
Prices shown reflect typical U.S. market pricing as of 2024–2026, before tax and labor. They vary by retailer and promotions.
- Conventional flooded 12V battery (non-AGM): commonly around $90–$150 at discount retailers; about $100–$180 at major auto parts stores.
- AGM (absorbed glass mat) battery: commonly around $150–$260 at auto parts stores; $180–$300 for OEM or premium aftermarket models.
- OEM Honda replacement battery: typically about $150–$230 at a dealer, sometimes higher with installation included; warranty terms vary by seller.
Note: Core charges may apply (often $5–$15) and taxes vary by location. Always check current prices at your preferred retailer right before purchase.
Finding the right size for your Accord Sport
The exact group size and part number depend on the model year and trim. The Accord’s battery is a 12V lead-acid unit, and common group sizes for mid-size Hondas include options such as 35 and 51R, but this can vary. Confirm the correct size by checking the owner’s manual, the current battery label, or using a VIN-based lookup at a retailer.
How to verify the right fit
Look for the “Group Size” on the label, compare cold-cranking amps (CCA) and reserve capacity with the replacement you’re considering, and verify compatibility using the retailer’s online lookup with your vehicle’s year, model, and engine.
Where to buy and what to expect during installation
Buy options range from Honda dealers to independent shops and big-box auto parts chains. Prices and installation charges vary by location and service level.
- Honda dealership: Higher battery prices, but OEM fit guaranteed; installation may be included in the service or billed separately (often $20–$60 in many markets).
- Auto parts stores (AutoZone, Advance Auto Parts, O'Reilly): Competitive pricing for both standard and AGM batteries; installation sometimes offered for a small fee if purchased there, otherwise DIY is common.
- Online retailers and warehouse clubs (Costco, Amazon, etc.): Often the lowest headline prices; confirm local availability, warranty terms, and whether installation is needed from a local shop.
Warranties for batteries commonly range from 2 to 4 years for standard units and longer for AGM or OEM models. Check the warranty terms before purchase.
Summary
For a Honda Accord Sport, plan on spending roughly $100–$250 for the battery itself, with total cost including installation typically higher. Always verify the correct group size and capacity for your specific model year and trim, compare dealer vs aftermarket options, and consider an AGM if you want longer life and better performance in extreme temperatures.
