The 2004 Honda CR-V generally uses a standard 12-volt lead-acid battery, typically sized as Group 35.
Typical battery size and specs
The group size defines the fit in the engine bay and the terminal layout. Cold-cranking amps (CCA) indicate starting power, and reserve capacity (RC) reflects how long the battery can run essential systems if the alternator isn’t charging.
- Group size: Group 35 is the common replacement size for most 2004 CR-V models. In some markets or configurations, Group 24F may be encountered; always confirm fit against your current battery or vehicle documentation.
- Battery type and voltage: 12-volt sealed lead-acid (maintenance-free) battery.
- CCA range: Replacement batteries typically span roughly 350–600 CCA, with higher CCA preferred in colder climates to improve starting performance.
- Reserve capacity: RC is usually in the 60–100 minute range depending on the exact battery model.
When replacing, aim for a Group 35 battery with a CCA rating appropriate for your climate and electrical needs, and ensure the dimensions and terminal layout match your CR-V’s tray and connections.
How to verify the exact size for your vehicle
To be certain you buy the correct battery, use these quick verification steps.
- Check the battery label: Look for "Group Size" or a code like "35" or "24F" on the top or side of the battery.
- Consult the owner's manual or a Honda replacement parts catalog for the exact group size for your trim and engine.
- Provide your VIN to an auto parts store or Honda dealer to receive the correct battery model.
- Measure or compare terminal arrangement to ensure proper fit and avoid interference with wrenches and hoses.
Having verified the correct size and CCA, you can select a compatible battery with confidence and ensure proper fit and performance.
OEM vs aftermarket considerations
OEM batteries are designed to match Honda specifications exactly, ensuring fit and discharge characteristics. Aftermarket options can offer similar or higher CCA and sometimes lower price, but verify fit, warranty terms, and corrosion resistance. Always choose a Group 35, 12V battery with a CCA rating that meets or exceeds your vehicle’s requirements.
Summary
For a 2004 CR-V, the standard replacement battery is a 12-volt lead-acid unit in Group 35. Always confirm the exact group size and CCA for your climate and vehicle configuration by checking the battery label, the owner's manual, or a parts professional. Choosing the correct Group 35 battery with adequate CCA ensures reliable starts and performance across seasons.
