What Type of Battery Does a Honda Pilot Use?

Most Honda Pilot models use a 12-volt Group 24F automotive battery. Trims equipped with Auto Idle Stop (start/stop) typically require an AGM (Absorbent Glass Mat) Group 24F battery, while non–Idle Stop models can use either AGM or conventional flooded lead-acid in Group 24F. Always confirm in your owner’s manual or under-hood label for your specific model year and trim.

The standard 12‑volt battery specification

Across generations, the Pilot’s under-hood starter battery has remained a conventional 12‑volt unit sized to Group 24F. Below are the key specs that apply to most Pilots, useful when shopping for a replacement.

• Group size: 24F (reverse-terminal layout, typically with the positive post on the left when the posts face you)
• Chemistry: AGM required or strongly recommended for models with Auto Idle Stop; flooded lead-acid acceptable for many non–Idle Stop trims
• Cold Cranking Amps (CCA): commonly 550–800 CCA; 650+ CCA is advisable in cold climates
• Reserve Capacity (RC): typically around 120 minutes or higher
• Physical dimensions (approx.): 10.25 × 6.8 × 8.9 inches (260 × 173 × 225 mm)

These specifications ensure proper fit, electrical performance, and terminal orientation for the Pilot’s battery tray and cables, reducing risk of installation or reliability issues.

Model-year and trim nuances

While Group 24F is consistent, battery chemistry and features may vary by generation and equipment such as Auto Idle Stop. Here’s a high-level guide to help narrow your choice.

• 2003–2008: Group 24F flooded lead-acid standard; AGM optional and compatible.
• 2009–2015: Group 24F remains standard; AGM can improve durability if the vehicle sees short trips or heavy accessory use.
• 2016–2022 (3rd gen): Group 24F across trims; models equipped with Auto Idle Stop generally specify AGM for the added cycling demands.
• 2023–2025 (4th gen): Group 24F continues; AGM is commonly fitted or recommended on trims with Auto Idle Stop. Check the under-hood label or manual.

Because equipment packages vary by trim and market, the most reliable source for your exact requirement is the owner’s manual and the battery label installed from the factory.

Choosing the right replacement

To avoid fitment problems and ensure your Pilot’s electrical systems perform correctly, follow these steps when selecting a battery.

1. Confirm group size: Verify Group 24F in your owner’s manual or the existing battery label.
2. Identify Auto Idle Stop: If your Pilot has start/stop, choose an AGM battery designed for deep cycling.
3. Match or exceed ratings: Choose a battery that meets or exceeds the original CCA and RC specifications.
4. Check terminal orientation: Ensure reverse-terminal (24F) layout to match cable reach and polarity.
5. Fitment and hold-down: Confirm the case height and base match the tray and hold-down clamp.
6. Perform BMS reset: After installation, have a shop or scan tool reset the Battery Management System (if applicable) to ensure proper charging and Idle Stop operation.

Taking these precautions helps maximize battery life, prevents electrical faults, and ensures safety features like Auto Idle Stop work as intended.

What about the key fob?

If you were asking about the remote, most Honda Pilot key fobs use a single CR2032 coin cell battery.

• Common coin cell: CR2032 for most recent Pilots; verify by opening the fob or checking the manual.
• Less common variants: Some older fobs may use CR1616 or another coin size—always confirm before buying.
• Handling tip: Avoid touching the flat faces of the new coin cell with bare fingers to prevent residue reducing contact.
• No reprogramming: Replacing the coin cell does not typically require reprogramming the fob.

A quick visual check of the old coin cell or a glance at the manual ensures you purchase the correct size and avoid repeated trips.

Cost, lifespan, and maintenance

Understanding typical costs and service intervals can help you plan replacements and avoid unexpected no-starts.

• Typical cost: Flooded Group 24F batteries often run $120–$200; AGM versions about $180–$300, depending on brand and warranty.
• Lifespan: Expect roughly 3–5 years; AGM can offer better durability, especially with frequent start/stop cycles.
• Environment impact: Extreme heat, deep discharges, and many short trips shorten battery life.
• Warning signs: Slow cranking, dimming lights at idle, or frequent Auto Idle Stop deactivation can indicate a weak battery.
• Warranty: Many batteries include 2–3 years of free replacement; keep your receipt for claims.

Regular checks of resting voltage and charging-system health can extend battery life and reduce roadside surprises.

Summary

The Honda Pilot generally uses a 12‑volt Group 24F battery. For trims with Auto Idle Stop, choose an AGM Group 24F to handle increased cycling; non–Idle Stop models can use either AGM or flooded in the same group size. Verify your exact requirement in the owner’s manual or on the battery label, and consider a BMS reset after installation for optimal performance. For the key fob, most Pilots use a CR2032 coin cell.
