What size battery is in a 2014 Honda Accord?

A 2014 Honda Accord uses a 12-volt lead-acid battery. The exact group size varies by engine and trim, but common replacements are Group 35 or Group 51R. Always verify with the battery label or the owner's manual to get the correct size for your specific model.

Battery size by engine and trim

The Accord lineup in 2014 offered a 2.4-liter four-cylinder engine and a 3.5-liter V6, plus a Hybrid variant. The 12-volt battery that powers the starter and electrical accessories is the same family, but the exact group size can differ by engine configuration and trim. Some owners report Group 35, while others report Group 51R. To ensure proper fit and performance, confirm the exact size from the battery label or Honda’s OEM specifications.

• Group 35: A commonly used size for mid-size sedans with similar electrical load, often found in 2.4L gasoline models.


• Group 51R: A slightly smaller footprint used on certain trims or configurations, sometimes seen in V6 or specific equipment packages.

Note: The 12-volt battery is separate from the hybrid high-voltage battery used in the Accord Hybrid, which has its own specifications and maintenance considerations.

How to verify the correct size

Before replacing or ordering a battery, check these sources to confirm the correct group size for your specific car:

• Inspect the battery itself for a label that reads "Group Size" (for example, 35 or 51R).


• Consult the owner's manual or the Honda Genuine Parts catalog for your exact VIN.


• Bring the existing battery or the vehicle information to an auto parts store to match the size and CCA rating.

Using the correct size ensures proper fit, electrical performance, and warranty compliance.

Hybrid variant note

The 2014 Honda Accord Hybrid uses a high-voltage traction battery for propulsion, while the standard 12-volt battery powers accessories and starting circuitry. If you own a hybrid, refer to the hybrid-specific maintenance guide for the exact battery specs and replacement procedures.

Summary

The 2014 Honda Accord's standard 12-volt battery size is not fixed to one single group size; it commonly falls within Group 35 or Group 51R depending on engine and trim. Verify the exact size by checking the battery label, the owner's manual, or Honda’s parts catalog. The hybrid variant uses a separate high-voltage system in addition to the conventional 12-volt battery.
