A 2010 Honda Fit requires a standard 12-volt lead-acid car battery of the correct group size. In North America, Group 51R is the common replacement size, while Group 35 is used in some markets. Always verify the exact size and CCA on your current battery or in the owner's manual before purchasing.
Battery type and OEM specs
The 2010 Honda Fit uses a conventional 12-volt lead-acid battery (flooded type) with no stop-start system. Replacement batteries should match the original group size, cold-cranking amps (CCA), and amp-hour (Ah) rating. While an AGM battery is available, it’s not required for this model unless you have special equipment or preferences.
Common group sizes by market
Before you buy, confirm the exact group size printed on your current battery or in your owner's manual. The two most common options for this model are:
- Group 51R
- Group 35
Note: Availability varies by region and vehicle trim. If your replacement battery doesn’t fit, double-check the measurement and terminal layout or consult a Honda dealer.
CCA and capacity: what to look for
Choosing the right cold-cranking amps (CCA) and capacity (Ah) ensures reliable starts in different climates and enough reserve power for accessories. Use these guidelines when shopping:
- General replacement range for most 2010 Fits: 350–460 CCA and 40–60 Ah
- Cold climates (very cold winters): aim for 520–640 CCA to start reliably in low temperatures
- Ambient conditions and electronics: consider higher Ah (40–60 Ah) if you regularly use features like heated seats, premium audio, or a lot of driving in the cold
Most replacement batteries meet or exceed the original CCA/Ah ratings; avoid underrating and ensure the battery fits the tray and terminals.
Other considerations
When replacing, you may choose standard flooded batteries or, if you prefer, an absorbed glass mat (AGM) battery. AGM can offer longer life and better performance in extreme conditions, but they’re more expensive and not required for a factory-equipment setup.
Installation tips
Always disconnect the negative terminal first and reconnect it last. Clean corrosion, ensure terminals are tight, and apply dielectric grease to prevent future corrosion. If you’re not comfortable replacing it yourself, a professional service can perform the installation and battery registration if required by your car’s electronics.
Warranty and disposal
Most batteries come with a 2–4 year warranty depending on brand and region. Recycle your old battery at an automotive retailer or a hazardous-waste facility for proper disposal.
Where to buy and based on your budget
Popular options include OEM Honda batteries, and aftermarket brands such as Bosch, Duralast, Interstate, Exide, or Yuasa. Prices vary by brand and CCA; consider warranty length when comparing options.
Summary
In short, a 2010 Honda Fit uses a standard 12V lead-acid battery, with Group 51R as common in North America and Group 35 in some markets. Match the CCA and Ah to the original spec, verify fit for your climate, and decide between traditional flooded or AGM if you want higher performance. Always replace with the correct size and maintain proper installation to ensure reliable starts and long life.
