What size battery does a Honda Fit use?

For most Honda Fit models sold in the U.S. and Canada (model years 2007–2020), the correct 12‑volt replacement is a BCI Group 151R battery with reverse terminals; many owners also upgrade to a slightly larger Group 51R with a tray/hold‑down swap. Below, we explain fitment by model year, key specs, and how to confirm the right battery for your specific car and market.

The quick specs most owners need

If you’re replacing the 12‑volt battery in a North American Honda Fit, these are the common sizes and specs you’ll encounter and why they matter.

• Primary fitment (US/Canada 2007–2020): BCI Group 151R, 12 V, reverse polarity (positive post on right)
• Typical dimensions (151R): about 8.94″ L × 5.06″ W × 8.75″ H (227 × 129 × 222 mm)
• Typical ratings (151R): 325–410 CCA; 40–70 minutes reserve capacity, depending on brand
• Common upgrade: BCI Group 51R (slightly longer), usually requires a different tray/hold‑down; offers higher CCA/RC
• Battery type: Flooded lead‑acid is standard; AGM/EFB only if specified (e.g., some start‑stop or hybrid/Jazz markets)

These specs cover the vast majority of routine replacements. Always match terminal orientation and physical size to ensure the leads reach correctly and the hold‑down clamps secure the case.

Year-by-year and market notes

This breakdown helps you match the battery group to your model year and region, and flags exceptions such as hybrid or start‑stop variants found outside North America.

• 2007–2008 Honda Fit (US/Canada): BCI Group 151R
• 2009–2014 Honda Fit (US/Canada): BCI Group 151R
• 2015–2020 Honda Fit (US/Canada): BCI Group 151R; some owners retrofit 51R with tray/hold‑down change
• Honda Fit/Jazz with idle‑stop or hybrid systems (markets outside North America): often require EFB or AGM in a region‑specific size; check the under‑hood label and owner’s manual
• Fourth‑generation Honda Jazz (2020–present, markets outside North America): uses a 12‑V auxiliary battery sized to regional standards (commonly a compact DIN/JIS unit); follow the vehicle label/manual for the exact type

Because battery standards differ by market (BCI in North America, JIS/DIN elsewhere), the safest approach outside the U.S./Canada is to read the existing battery label and confirm the exact spec in the owner’s manual.

How to confirm the correct battery on your car

Before you buy, these quick checks will help you verify compatibility and avoid returns.

1. Read the existing battery’s label: Look for “151R” or “51R” (BCI) in North America, or a JIS/DIN code elsewhere.
2. Check terminal orientation: The Fit typically uses reverse terminals (positive on the right when posts face you).
3. Measure the tray and hold‑down: Ensure length, width, and height match; 51R is longer than 151R.
4. Match battery technology: If your car has start‑stop or is a hybrid/Jazz variant, use the specified EFB/AGM type.
5. Verify CCA for climate: Colder regions benefit from higher CCA within the correct group size.

A few minutes of verification saves time and ensures the posts line up, the cables reach, and the battery clamps secure the case correctly.

Replacement and upgrade tips

These practical pointers cover installation details and considerations if you’re moving from 151R to 51R for more capacity.

• Hold‑down hardware: A 51R typically requires a 51R‑specific tray and clamp to secure the longer case.
• Cable reach: Confirm the positive lead comfortably reaches the right‑side post without strain.
• Electrical memory: Use a memory saver if you want to preserve radio presets and window auto‑up/down calibration.
• Terminal torque: Tighten clamps snugly (about 5–7 N·m/45–60 in‑lb) to avoid loose connections without damaging posts.
• Corrosion prevention: Clean terminals and apply dielectric grease or protectant to reduce future buildup.
• Warranty and spec: Choose a reputable brand with a clear warranty and meet or exceed OE CCA/RC ratings.

Following these tips helps ensure a secure installation, reliable starts, and longer battery life—especially if you opt for a higher‑capacity upgrade.

When to consider AGM or EFB

AGM or EFB batteries are typically only necessary if your specific Fit/Jazz is equipped with start‑stop or specified for enhanced cycling by the manufacturer. In standard U.S./Canada gasoline Fits without start‑stop, a quality flooded 151R is sufficient, while AGM can be an optional durability upgrade for short‑trip or high‑accessory use.

Bottom line

For U.S. and Canadian Honda Fits from 2007–2020, a BCI Group 151R 12‑volt battery with reverse terminals is the direct replacement; a Group 51R can be used with the correct tray/hold‑down for more capacity. Outside North America, verify the region‑specific JIS/DIN size and, for start‑stop or hybrid variants, use the specified EFB or AGM type.

Summary

Most Honda Fits in North America take a BCI Group 151R battery (reverse terminals), with common ratings around 325–410 CCA. A Group 51R is a popular capacity upgrade if you also change the tray/hold‑down. For non‑U.S./Canada models—especially start‑stop or hybrid Jazz variants—confirm the exact JIS/DIN size and battery technology (EFB/AGM) listed on the under‑hood label and in the owner’s manual.

What size battery is in a 2011 Honda Fit?

The standard battery size for a 2011 Honda Fit is a Group Size 151R. This battery features a specific physical size, has a top post terminal, and typically offers around 340 Cold Cranking Amps. Some alternative batteries, like the 51R, are mentioned as possibilities but require modifications for proper fitment.
 
Key Specifications for the Group Size 151R Battery:
