The 2009 Honda Accord uses a standard 12-volt automotive battery. In most trims this is a conventional, maintenance-free flooded lead-acid battery in Group 35 size, though some production runs or trims may use Group 24F. Always verify by checking the current battery label or the owner's manual, and note that the Accord Hybrid (if your model is not the hybrid version) relies on a separate high-voltage battery system.
Identifying the right battery for your car
To ensure you buy the correct replacement, use the following guidelines when selecting a new battery for the 2009 Accord. The details below cover the most common configurations for this model year.
Before listing the options, keep in mind that the exact group size and ratings can vary by production date and trim. Check your existing battery label or the owner's manual to be sure.
- Group size: The typical size for a 2009 Accord is Group 35. Some vehicles may require Group 24F; verify the label on your current battery.
- Battery type and construction: Most are maintenance-free flooded lead-acid (sealed). AGM versions are uncommon on the standard ICE Accord but may be used in specialized or high-demand setups.
- Key electrical ratings: Look for cold-cranking amps (CCA) and reserve capacity (RC) on the battery label and choose a replacement that meets or exceeds the OEM specifications in your manual.

Additional tips for installation and maintenance
When replacing the battery, follow proper safety steps: wear eye protection and gloves, disconnect the negative terminal first, then the positive, and reconnect in reverse order. Dispose of the old battery at an approved recycling facility or the store where you purchase the new one.
