Battery options for the Accord Sport
Below are the common battery types you’ll encounter when replacing a Honda Accord Sport battery, along with typical price ranges for parts.
- OEM Honda battery (12V, AGM, often group size 51R) — typically $180–$320 for parts; installation may add $60–$150.
- Aftermarket AGM battery (brands like ACDelco, Bosch, Motorcraft, etc.) — generally $150–$250 for parts; some shops include installation.
- Conventional flooded lead-acid battery (less common for current start-stop models) — commonly $100–$180 for parts; installation extra; availability varies by retailer.
- High‑end premium AGM or specialty batteries — usually $250–$350+ for parts; installation extra; offered by some retailers for longer warranties.
- Lithium 12V battery options (rare for this application) — typically $400–$600+; installation varies; not standard for most Accord Sport models.
Bottom line: for most Accord Sport owners, an AGM battery—whether OEM Honda or a reputable aftermarket AGM—is the standard choice due to start-stop system requirements and reliability.
Cost overview: parts and installation
Here are typical price ranges for batteries and professional installation, reflecting differences between retailers, locations, and service options.
- Conventional flooded 12V battery (parts only) — about $100–$180
- AGM replacement (non-OEM brands) — about $150–$250
- OEM Honda AGM replacement (parts only) — about $180–$320
- Labor/installation — about $60–$150 at independent shops; dealership install may be higher
- Total installed price (battery plus labor) — roughly $240–$470 depending on options and location
Prices vary by region, retailer, and whether core charges or disposal fees apply. Warranties typically range from 1 to 4 years, with longer coverage often available on OEM or premium AGM units.
Battery size and compatibility
The Accord Sport’s 12V battery must fit the vehicle’s group size and terminal layout. Common group sizes printed on batteries include 51R or 35, but the exact specification depends on the model year and equipment. Always verify the correct group size and hold-down fit before purchasing to ensure compatibility with clamps and connectors.
Warranty and service considerations
Most aftermarket AGM batteries come with 2–4 year replacement warranties (often prorated), while OEM replacements can offer longer coverage. If you opt for dealership installation, you’ll typically pay more in labor, but you may gain bundled diagnostics or disposal services. If you DIY, plan for proper recycling of the old battery and adherence to safety guidelines.
Summary
For a Honda Accord Sport, replacing the battery typically falls in the mid-range of consumer auto parts pricing. Most buyers choose an AGM battery to ensure compatibility with the car’s start-stop system, with total installed costs commonly running between $240 and $470, depending on brand, year, and service location. Always confirm the correct group size, start-stop compatibility, and warranty terms when shopping, and weigh OEM versus aftermarket options based on your priorities for reliability and coverage.
