The 2017 Honda Fit uses a standard 12-volt automotive battery. In the United States, the typical replacement size is Group Size 51R, but you should verify the exact fit with your owner's manual or the battery label to be certain.
Understanding the battery needs of the 2017 Fit
The Fit is a compact hatchback with a conventional 12-volt lead-acid battery located in the engine bay. The correct battery size depends on tray space, terminal layout, and electrical requirements rather than engine size alone. Getting the right group size ensures the battery fits properly and connects without issue.
Market variations exist. In North America, 51R is the most commonly recommended size for the Fit, while some regions may list alternative group sizes due to different suppliers or packaging. When shopping, always compare the group size, cold-cranking amps (CCA), reserve capacity (RC), and terminal configuration to your current battery.
Here are replacement battery sizes that are commonly cited for the 2017 Fit. These options are general fits used by retailers; always confirm compatibility with your VIN and tray dimensions.
- Group Size 51R — widely recommended for the 2017 Fit in North America; typically offers a suitable balance of power and fit.
- Group Size 35 — listed for some markets; verify that the dimensions and terminals match your vehicle before purchasing.
Note: The exact group size for your car can vary by market and trim. Always verify with the dealer, owner’s manual, or the current battery label.
How to verify the exact size for your car
To determine the precise group size for your 2017 Honda Fit, use these steps:
- Inspect the current battery label for the Group Size marked on the case (for example, "51R" or "35").
- Consult the owner's manual, which lists the recommended battery group size and specifications for your trim and market.
- Enter your VIN on a reputable auto parts retailer or Honda dealership site to pull the exact fitment requirements for your vehicle.
- When in doubt, have a professional verify the fit by comparing dimensions and terminal layout to your current battery.
Once you identify the correct group size, you can select a replacement battery with matching CCA and RC to suit your climate and driving needs.
Battery specifications to consider
Apart from group size, you should evaluate cold-cranking amps (CCA) and reserve capacity (RC). For the Fit, replacement batteries typically range in CCA from roughly 300 to 550, depending on the model and brand, with RC often around 60 to 100 minutes. If you drive in very cold weather or rely heavily on electrical accessories, a higher-CCA battery may be beneficial. Ensure the battery terminals align with your vehicle’s wiring and that the overall dimensions fit the engine bay tray.
Summary
The 2017 Honda Fit uses a 12-volt automotive battery, with Group Size 51R being the most common replacement in North America. Always verify the exact size via the owner's manual, current battery label, or VIN-based parts lookup, and consider CCA and RC to match your climate and driving needs.
