When it comes to maintaining your Mazda 3, one of the essential components to keep an eye on is the car battery. It’s the heart of the electrical system, and choosing the right size and specifications is crucial for optimal performance. Here’s what you need to know about Mazda 3 car battery sizes.
Battery Size Specifications
The Mazda 3 has been designed to accommodate specific battery group sizes. Depending on the year and model of your Mazda 3, the battery group size may vary:
- Group 35 Battery: This is the most common size for Mazda 3 models from various years. The dimensions for this battery are 9.0625 x 6.9375 x 8.875 inches (230 x 175 x 225 mm)².
- Group 47 Battery: Some models, particularly the 2020 Mazda 3, can also use this battery size, which measures 9.5625 x 6.9375 x 7.5 inches (242 x 175 x 190 mm)².
- Group 21R Battery: This size is compatible with the 2014 Mazda 3, with dimensions of 8.1875 x 6.8125 x 8.75 inches (208 x 173 x 222 mm)².

Power Ratings
Apart from the physical size, the power ratings of the battery are also important:
- 12-volt 60Ah/20HR or 12V-65Ah/20HR SLI battery: These are recommended for the 2.0L or 2.5L Skyactiv engine⁴.
- Q85 type: Required if your Mazda 3 features the i-ELOOP regenerative braking system⁴.
Choosing the Best Option
When selecting a battery, consider the following:
- Compatibility: Ensure the battery size fits your specific Mazda 3 model.
- Cold Cranking Amps (CCA): Higher CCA batteries perform better in cold weather.
- Reserve Capacity (RC): A higher RC means the battery can run longer with the engine off.
- Warranty: Look for batteries with a longer warranty period for added peace of mind.
Conclusion
Your Mazda 3 deserves a reliable and efficient battery that meets its specifications. By understanding the battery group sizes and power ratings, you can make an informed decision that ensures your vehicle runs smoothly.
