A 2017 Honda Fit uses a standard 12-volt automotive battery (lead-acid) for starting and onboard electronics; there is no hybrid high-voltage battery in this model.
Battery basics for the 2017 Honda Fit
Understanding the 12V battery helps with replacement, maintenance, and troubleshooting for day-to-day reliability.
What you should know
The Fit’s 12V system powers starting, lights, and accessories while the engine is off. The high-voltage battery used in hybrids is not present in the standard gasoline model.
These are the typical specifications to know when shopping for a replacement:
- Battery type: 12-volt automotive battery, lead-acid and sealed (maintenance-free).
- Group size: Most replacements are Group 35 (or an equivalent size recommended for your market). Always verify the exact OEM part number for your vehicle.
- Capacity: Usually in the ~35–45 Ah range; check the label or owner’s manual for the precise rating.
- Voltage: 12V system; no high-voltage traction battery.
- Expected lifespan: About 3–5 years under typical driving conditions.
When in doubt, consult the owner’s manual or a Honda dealer to confirm the exact spec for your VIN.
Choosing and installing a replacement
Before purchasing a replacement, confirm the correct battery size and terminals, and plan for safe installation.
- Check the OEM part number or Group Size in the owner's manual or by contacting a dealer.
- Choose a reputable brand with a compatible 12V AGM or flooded lead-acid option if you want longer life in extreme climates.
- Ensure correct terminal orientation (positive/negative) and compatible connector types.
- Follow safety precautions: disconnect the negative terminal first, then the positive; wear eye protection and gloves.
- Have the alternator and charging system tested if the battery frequently dies or won’t hold a charge.
Using the right battery and proper installation reduces risk of failure and protects other electrical systems.
Maintenance tips
Routine care can extend battery life and reliability for the Fit’s 12V system.
- Keep terminals clean and tight to prevent parasitic drain and starting issues.
- Look for white or blue corrosion; clean with a baking soda solution and a wire brush if needed.
- Ensure the charging system maintains about 13.5–14.5 volts when the engine is running.
- In very cold climates, consider a battery with higher cold-cranking amps (CCA) for easier starting in winter.
Proper maintenance helps ensure dependable starts and minimizes unexpected battery failures.
Summary
The 2017 Honda Fit relies on a standard 12-volt lead-acid automotive battery (sealed, maintenance-free) for starting and accessory power. Replacement parts are typically Group Size 35 (or an equivalent) with a capacity generally in the 35–45 Ah range; always confirm the exact part number for your market. For best results, follow the manufacturer’s guidance and recycle old batteries responsibly.
