The 2004 Honda Pilot uses a standard 12-volt automotive battery. The most common replacement group sizes are 24F or 35, with cold-cranking amps typically around 600–700. Always confirm the exact size by checking the battery label or the owner's manual.
The following report explains the battery type, the typical sizes for this model year, and how to ensure you buy the right unit for your vehicle.
Battery type and fit
For most 2004 Pilots, you’ll be replacing a conventional flooded 12-volt battery. These are sealed, maintenance-free lead-acid units designed to start a gasoline engine in a wide range of climates. They are not hybrid or plug-in batteries.
Common replacement group sizes
When shopping, you’re most likely to encounter two group sizes that fit the Pilot’s battery tray. The under-hood label on your current battery will specify the exact size.
- Group Size 24F — a common size for mid-size SUVs; typically about 650–700 CCA; may be top-post or side-terminal depending on the brand
- Group Size 35 — another widely used option; typically about 600–650 CCA; terminal configuration varies by supplier
Regardless of size, ensure the replacement matches the vehicle’s CCA rating, reserve capacity, and terminal layout to avoid fitment or starting issues.
How to pick the right battery
Check the owner’s manual or the current battery’s label for the exact group size and CCA recommendation. If you’re replacing on your own, a reputable auto parts store can confirm compatibility by year, make, model, and engine size. When in doubt, choose a maintenance-free, 12-volt flooded lead-acid battery with the preferred group size and CCA.
Installation tips and maintenance
Safety first: disconnect the negative terminal first, then the positive; reinstall in reverse order. After installation, check for clean terminals and secure mounting. Periodically inspect the battery for corrosion, clean the terminals, and test the charging system to ensure the alternator is maintaining proper voltage.
Where to buy
Reliable options include auto parts chains, Honda authorized parts, or OEM replacements. Always cross-check the battery size, CCA, and warranty when shopping.
Summary
A 2004 Honda Pilot uses a standard 12-volt lead-acid automotive battery, with common group sizes 24F or 35 and a typical CCA range around 600–700. Verify the exact specification on the existing battery label or in the owner’s manual to ensure a proper fit and reliable starting performance.
