How Much Should a Honda Battery Cost?

For most Honda cars and SUVs, a standard 12‑volt replacement battery typically costs $120–$230 for the part alone, or $220–$450 installed at a dealership or service shop. Absorbent Glass Mat (AGM) batteries used in some newer idle‑stop models usually run $220–$330 for the battery. High‑voltage hybrid traction batteries (not the 12‑volt) can cost $2,000–$6,000+ installed if out of warranty, while key‑fob coin cell batteries are about $2–$8. Below is a detailed breakdown of what drives the price and how to get a fair deal in 2025.

What “Honda battery” can mean

People often mean different things by “Honda battery.” Most owners are referring to the 12‑volt starter battery found in every Honda. Hybrid and plug‑in models also have a high‑voltage traction battery that’s entirely separate and far more expensive. Finally, key fobs use inexpensive coin-cell batteries.

Typical prices in 2025 (United States)

12‑volt battery (most Hondas)

The majority of Hondas use a conventional 12‑volt lead‑acid battery. Some newer trims with idle‑stop or higher electrical loads require AGM batteries, which cost more than traditional flooded batteries. Here are common price ranges you’ll encounter:

• Economy flooded (common sizes like Group 51R, 35, 24F): $120–$170 at big-box stores and warehouse clubs (Walmart, Costco/Interstate), typically parts only.
• Midrange flooded: $170–$230 from auto parts retailers (AutoZone, Advance, O’Reilly, NAPA) and many independents; often includes better CCA/RC and longer warranties.
• AGM (often Group 47/H5 or H6 for idle‑stop or higher‑load models): $220–$330 for the battery; installation may add $30–$120 depending on shop and any BMS reset.
• Dealer-installed packages: $250–$450 total, depending on battery type, model, and region; typically includes installation, battery sensor/BMS reset, and warranty handling.
• Labor, fees, and core charge: Installation $20–$60 at independents, $40–$120 at dealers; core deposit $10–$30 (refunded when you return the old battery); taxes vary by state.

Prices vary by region and supply. Expect seasonal sales, especially before winter and during holiday weekends. Always compare the out‑the‑door price, including taxes, core charges, and installation.

Hybrid and EV high‑voltage batteries

Honda hybrids (e.g., Accord Hybrid, CR‑V Hybrid, Insight) and older IMA models (e.g., Civic Hybrid) use high‑voltage traction packs separate from the 12‑volt battery. These are costly and usually covered by longer emissions warranties when newer. Out of warranty, ballpark costs are:

• Modern Honda hybrid traction batteries (lithium-ion in Accord Hybrid, CR‑V Hybrid, Insight): roughly $2,500–$5,500 for parts plus $300–$1,000 labor; $2,000–$6,500 total is typical.
• Older Civic Hybrid IMA packs (NiMH): often $1,500–$3,000 for remanufactured packs; OEM new can be higher.
• Warranty coverage: Generally 8 years/100,000 miles in most states; up to 10 years/150,000 miles in CARB states. Confirm your VIN-specific coverage.

Because diagnostics, calibration, and safety procedures are involved, traction battery work should be performed by qualified shops or dealers. Always verify warranty status before paying out of pocket.

Key fob batteries

Honda key fobs typically use coin cells (often CR2032 or CR2025). You can replace these yourself with a small screwdriver.

• Coin-cell battery: $2–$8 each at retailers or online.
• Dealer or locksmith replacement service: $10–$25, sometimes bundled with a quick inspection.
• No reprogramming is required for simple battery swaps; just replace the cell and reassemble the fob.

Buying a multi-pack coin cell can reduce the per‑battery cost and ensures you have a spare on hand.

What affects the price of a Honda 12‑volt battery

Several technical and market factors determine what you’ll pay. Knowing these helps you choose the right battery without overspending.

• Battery group size and fitment: Common Honda sizes include 51R, 35, 24F, and for newer idle‑stop models, 47/H5 or H6. Correct fit and terminals are essential.
• Type and performance: AGM costs more than flooded; higher cold‑cranking amps (CCA) and reserve capacity (RC) also increase price.
• Brand and warranty: Premium brands with longer free‑replacement periods (e.g., 36 months) are priced higher.
• Retailer vs. dealer: Dealers bundle installation and BMS reset; parts stores may offer lower battery prices and free testing/installation on accessible layouts.
• Installation complexity: Some models are straightforward; others need trim removal and a battery management system (BMS) reset.
• Region, demand, and timing: Hot climates shorten battery life, increasing demand; seasonal sales can lower prices.
• Core charges and recycling: Returning your old battery secures a core refund and avoids extra cost.

If your Honda uses idle‑stop, stick with the required AGM type; downgrading to flooded can shorten battery life and cause system faults, erasing any initial savings.

How to get the best deal

You can often save money and still get a high-quality battery by following a few practical steps.

1. Check your owner’s manual or use a fitment guide to confirm the exact group size and whether AGM is required.
2. Compare total out‑the‑door prices, including installation, BMS reset, taxes, and core charges.
3. Look for promotions: warehouse clubs (Costco/Interstate), big-box stores (Walmart EverStart), and parts retailers often run battery sales and coupon deals.
4. Ask about warranty terms (free replacement period vs. pro‑rated) and keep your receipt in your glovebox.
5. Verify battery age: choose one manufactured within the last 3–6 months (check date codes on the case).
6. Request a system test: many parts stores do free battery/alternator checks to confirm a weak battery before you buy.
7. Ensure a BMS/battery sensor reset after installation on newer Hondas so the charging system calibrates correctly.

A little homework can easily shave $30–$100 off the price while ensuring you get the right battery with solid warranty coverage.

Signs your Honda needs a new 12‑volt battery

Catching early symptoms helps you avoid a no‑start situation and protects electronic systems.

• Slow cranking, dim interior lights, or flickering headlights at idle.
• Electrical warnings, unstable idle‑stop operation, or repeated jump‑starts.
• Battery older than 3–5 years, especially in hot climates.
• Low state of charge after sitting; visible corrosion or swelling.

If you notice these signs, have the battery load‑tested and the charging system checked before replacing parts.

Model-specific quick notes

While exact fitment varies by year and trim, these guidelines cover many popular Hondas:

• Civic, older CR‑V, and many Fits/HR‑V: commonly Group 51R flooded; some trims may accept AGM upgrades.
• Accord (older gas models): often Group 24F or 35 flooded; check under-hood label or manual.
• Newer Accord, CR‑V, and other trims with idle‑stop: frequently Group 47/H5 (AGM) or similar; AGM is typically required.
• Hybrids: still use a 12‑volt battery (often AGM) in addition to the high‑voltage pack; follow the manual’s specification.

Always confirm with your owner’s manual, the under‑hood battery label, or a reputable fitment database using your VIN.

Expected lifespan

Battery life depends greatly on climate and driving patterns, which can influence when you’ll face replacement costs.

• Conventional flooded 12‑volt: typically 3–5 years; shorter in very hot regions or with frequent short trips.
• AGM 12‑volt: often 4–6 years thanks to better cycle durability.
• High‑voltage hybrid packs: designed for long life; many exceed warranty periods but replacement costs are significant once due.

Regular driving, avoiding deep discharges, and keeping terminals clean can extend battery life and delay replacement expenses.

Bottom line

For a typical Honda, budget $120–$230 for a quality 12‑volt battery or $220–$330 if your model requires AGM, with installed totals commonly $220–$450 depending on where you go. Hybrid traction batteries are a separate, far costlier item—often $2,000–$6,000+ out of warranty—while key‑fob batteries are just a few dollars. Confirm your exact battery type, compare out‑the‑door quotes, and ensure a proper BMS reset for the best results and value.

Summary

Most Honda 12‑volt batteries cost $120–$230 (flooded) or $220–$330 (AGM), with dealer-installed totals usually $250–$450. Hybrid traction batteries are far more expensive at $2,000–$6,000+ when not covered by warranty. Key‑fob batteries are $2–$8. Prices depend on battery type, group size, warranty, installation, and region; always verify fitment, compare all-in quotes, and ensure the BMS is reset after installation.
