How Much a Battery Costs for a 2015 Honda Odyssey in 2025

Expect to pay about $150–$220 for a standard flooded Group 24F battery and $230–$320 for an AGM (absorbed glass mat) option as of August 2025 in the U.S.; installed prices typically run $220–$380 at independent shops and $280–$420 at dealerships. The 2015 Honda Odyssey uses a Group 24F battery, and pricing varies by battery type, brand, warranty length, and where you buy it.

What the 2015 Odyssey Uses and Why It Matters

The 2015 Honda Odyssey is designed for a Group 24F battery (reverse-terminal orientation). Most models originally shipped with a conventional flooded lead-acid unit, but many owners opt for AGM batteries for better durability under heavy electrical loads or in extreme climates. While AGM is not strictly required, it can provide longer service life and improved performance, especially with frequent short trips or accessory use.

Typical 2025 Price Ranges

The following ranges reflect common retail pricing observed across national chains and warehouse clubs in mid-2025; your final cost will vary by region, brand, and promotions.

• Standard flooded lead-acid (Group 24F): approximately $150–$220
• AGM (Group 24F): approximately $230–$320
• Installed at independent shop: generally $220–$380 (parts and labor)
• Installed at Honda dealership: generally $280–$420 (parts and labor)
• Core charge (refundable when you return the old battery): typically $10–$35

These figures cover mainstream brands sold at retailers such as Walmart, Costco, AutoZone, Advance Auto Parts, O’Reilly, and dealer parts counters; sales, coupons, and membership pricing can shift totals significantly.

Key Specifications to Match

While price is a major factor, aligning the battery to your Odyssey’s requirements ensures reliability and longevity.

• Group size: 24F (do not substitute 24, which has opposite terminal orientation)
• Cold-cranking amps (CCA): look for roughly 600–750 CCA; higher is helpful in cold climates
• Reserve capacity (RC): higher RC provides better support for accessories when idling
• Warranty: 2–3 years free replacement is common; some add prorated coverage beyond that
• Type: flooded is budget-friendly; AGM offers better vibration resistance and deep-cycle tolerance

Matching these specs reduces the risk of starting issues, premature wear, or fitment problems in the battery tray and hold-down.

Where to Buy and What Affects the Final Bill

Consumers can choose between DIY purchase-and-install or having the battery installed professionally; both routes carry tradeoffs that influence cost and convenience.

• Big-box/warehouse clubs (e.g., Costco, Sam’s Club): often the lowest out-the-door price; limited lineup and installation services vary by location
• Auto parts chains (e.g., AutoZone, Advance, O’Reilly): broad selection, testing, and typically free installation on accessible batteries; frequent online coupons
• Dealerships: OEM-branded batteries and system resets included; higher labor rates, but convenient one-stop service
• Mobile installers: convenience at home or work; pricing usually in line with shops plus a service premium

Your ultimate cost will depend on brand, warranty length, whether you choose AGM, installation labor, shop fees, and whether you reclaim the core charge by returning the old battery.

Installation and System Reset Notes

Replacing the Odyssey’s battery is straightforward, but a few steps help protect electronics and ensure the charging system recognizes the new battery.

1. Use a memory saver if possible to preserve radio presets and window/door calibrations.
2. Remove the negative cable first, then positive; swap in the new Group 24F battery and secure the hold-down.
3. Reconnect positive first, then negative; apply anti-corrosion spray if available.
4. Perform an idle relearn and, if equipped with a battery sensor (common on Hondas of this era), execute a battery management/battery sensor reset using a scan tool or the manufacturer-recommended procedure.
5. Test the charging system (alternator output and battery voltage) to confirm proper operation.

Completing these steps helps the vehicle’s electrical system adapt quickly to the new battery and reduces the chance of erratic charging or idle issues.

When to Consider AGM Over Flooded

AGM batteries cost more upfront but can be a sound choice depending on how and where you drive.

• Frequent short trips or heavy accessory use (rear entertainment, phone charging, HVAC at idle)
• Hot or very cold climates that stress batteries
• Preference for longer service life and better vibration resistance

If you mainly drive longer highway trips in moderate weather, a quality flooded 24F unit offers strong value; otherwise, AGM may save hassles over time.

What to Watch for in Promotions and Warranties

Prices swing with promotions; stacking discounts can materially lower your total.

• Online-order discounts with in-store pickup at auto parts chains
• Coupon codes and loyalty rewards programs
• Warranty terms: length of free replacement, prorated coverage, and nationwide support

Combining an online code with a core return and free installation often yields one of the best values for a name-brand battery.

Bottom Line

For a 2015 Honda Odyssey, budget roughly $150–$220 for a quality flooded Group 24F battery or $230–$320 for AGM, with installed totals commonly $220–$380 at independents and $280–$420 at dealers in 2025. Confirm Group 24F fitment, aim for at least ~600 CCA, and consider AGM if your driving or climate is demanding. Returning your old battery for the core refund and timing purchases around promotions can meaningfully reduce the final price.
