2017 Honda Fit Battery Size
The 2017 Honda Fit uses a BCI Group 151R battery (Group 51R also fits), rated about 330-410 cold cranking amps (Flooded).
Key takeaways
- Battery: BCI Group 151R, 330-410 CCA, Flooded.
- Replace with the same Group 151R (Group 51R also fits).
- In cold weather, choose a battery at or above 410 CCA.
- It comes with a flooded battery; you can upgrade to AGM in the same group size.
- Battery type (OEM)
- Flooded
- Cold cranking amps (CCA)
- 330-410
- Terminal position
- Reversed-terminal layout (R)
- Dimensions (L×W×H)
- 207×174×175 mm
OEM is the small Group 151R; 51R is a larger upgrade that needs a hold-down/tray adjustment. Always confirm against your owner's manual or current battery label.
The right battery for your 2017 Honda Fit
Match the group size (Group 151R) and aim for at least 330 CCA - more in cold climates. A standard flooded battery is fine, or upgrade to AGM for longer life. A battery is heavy to ship, so buying in person can win once you count free install and the core-charge refund - but to compare prices and reviews:

Shop the Group 151R batteryWhat does a 2017 Honda Fit battery cost?
| Typical price | $80-200 |
| Typical service life | 3-5 years |
| Cost per year | ~$16-67 |
| Core charge | ~$22 (refundable) |
Expect roughly $80-200 for a standard flooded battery in Group 151R, which is what this car takes. Over a typical 3-to-5-year service life that works out to about $16-67 a year. You can fit an AGM in the same Group 151R size if you want the longer service life, and it will cost roughly $125-320 instead. It is an upgrade, not a requirement.
That is typical for Honda: only 6% of the 2015-and-newer Honda vehicles we hold specs for use AGM, so you are usually in the cheaper flooded bracket with this brand.

Do you need to register the battery?
This car came with a flooded battery and no smart charging system to satisfy, so there is nothing to register. Disconnect, swap, reconnect. You may need to reset the clock and radio presets, and that is the extent of it.
What Group 151R means
A BCI group number describes the battery's physical size and terminal layout, not its power. It is what guarantees the battery drops into the tray and the cables reach the right posts. A Group 151R case measures roughly 207 × 174 × 175 mm. Reversed-terminal layout (R).
Group 151R is one of the less common sizes, at 0.5% of the vehicles we hold specs for. It is still a catalogued BCI size rather than anything exotic, but a smaller store may need to order it, so it is worth calling ahead.
Group 51R also fit this vehicle. Alternate groups share the terminal layout and fit the tray, but check the hold-down clamp still engages before you drive off - a battery that shifts is a battery that fails early.
How many cold cranking amps?
Aim for 330 CCA at minimum. Cold cranking amps measure how much current the battery can deliver at 0°F, which is the one moment a battery is really tested. The 330-410 range reflects the different batteries fitted across this vehicle's trims and options. Going above the OEM rating is safe and does no harm - the starter draws what it needs and no more, so a higher-CCA battery is not "too strong" for the car. It is worth paying for if you park outside in a cold climate, and largely wasted money if you do not. Going below 330 is the one thing to avoid, because that is where hard winter starts come from.
How long it should last
A standard flooded battery typically lasts 3 to 5 years. Heat is what kills batteries, not cold - cold just exposes one that was already failing, which is why so many die on the first freezing morning after a hot summer. Short trips that never fully recharge it shorten its life too. Once this battery passes its third year, get it tested annually rather than waiting to be stranded.
The warning signs are worth knowing because they are easy to miss: cranking that sounds slower than it used to, headlights that dim at idle and brighten when you rev, or a car that starts fine every day until the first cold morning and then does not. A battery rarely warns you twice.

Where is the battery located on a 2017 Honda Fit?
Check the engine bay first - that is where most vehicles carry the battery.
