The 2020 Honda Fit uses a standard 12-volt automotive battery to power starting and onboard electronics. The most common replacement sizes are Group 51R or Group 35, depending on the market and trim.
Battery type and replacement considerations
The Fit is not a hybrid or electric vehicle, so its main traction system does not involve a high-voltage battery. The exact group size and rating are specified by Honda in the owner's manual and are typically printed on the current battery label. When replacing, you should match the OEM specifications for fit, capacity, and terminal layout to ensure reliable starting and electronics performance.
Common replacement sizes
For most 2020 Fits, the replacement options you’re likely to encounter fall into these two 12-volt group sizes. Always verify the exact size for your specific vehicle before purchasing.
- Group 51R 12V battery — a compact option that fits the Honda Fit’s engine bay layout.
- Group 35 12V battery — a slightly larger option that may be used when space allows or higher electrical demand is indicated.
Bottom line: Group 51R is common for this model, but Group 35 can be an appropriate alternative depending on market and trim. Always confirm the exact group size from the current battery label or the owner's manual.
How to verify the right battery for your car
To ensure you buy the correct battery, follow these steps:
- Check the owner's manual or Honda's official specifications for the exact battery group size and recommended CCA.
- Inspect the label on your current 12-volt battery for the group size and CCA rating.
- Measure the battery compartment dimensions (length, width, height) to ensure the replacement will fit under the hood and align with the terminals.
- Confirm terminal layout and polarity match your vehicle’s configuration (positive and negative terminal positions).
- Consider climate and electrical load: in very cold climates or with additional electrical accessories, an upgrade in capacity may be advisable.
Bottom line: always match the replacement to the OEM specifications to ensure proper fit and reliable starting performance.
Summary
The 2020 Honda Fit uses a conventional 12-volt lead-acid battery, not a high-voltage traction battery. The most common replacement sizes are Group 51R or Group 35, with the exact size depending on market and trim. Verify the precise group size and rating from the owner’s manual or the current battery label before purchasing, and ensure the replacement fits the space and terminal configuration. Regular maintenance and clean connections help ensure reliability.
