Battery Group Code 24 refers to a standardized classification for automotive batteries based on size, terminal placement, and power capacity. It ensures compatibility with specific vehicle models, particularly compact cars, motorcycles, and some marine applications. This code helps users select the correct battery, ensuring optimal performance and safety. Always check your vehicle manual to confirm Group 24 compatibility.
What Is a Group Size 24 Battery?
How Is Battery Group Code 24 Defined?
Battery Group 24 is defined by its physical dimensions: approximately 10.25 inches long, 6.8 inches wide, and 8.9 inches tall. It features top-mounted terminals (positive on the left) and delivers 70-85 Ah capacity with 650-800 CCA. These specifications ensure it fits designated battery trays and meets electrical demands for engines in smaller vehicles.
The standardization process for Group 24 batteries follows guidelines set by the Battery Council International (BCI). This ensures uniformity across manufacturers, allowing consumers to compare products reliably. For example, while weight may vary slightly between flooded and AGM variants, the core dimensions remain fixed. The 20-hour discharge rate (measured in amp-hours) and cold cranking amps (CCA) are critical metrics for evaluating performance in extreme temperatures. Below is a comparison of Group 24 with similar battery groups:

Terminal placement is another defining factor. Reverse terminal configurations (negative on the left) are sometimes labeled as “Group 24R” and require explicit compatibility checks.
Which Vehicles Use Battery Group Code 24?
Common applications include Honda Civic models (2012-2018), select Yamaha motorcycles, and smaller marine vessels like fishing boats. European compact cars such as the Volkswagen Golf often utilize this size due to limited engine compartment space.
Beyond automotive uses, Group 24 batteries power auxiliary systems in RVs and solar storage setups. Their moderate capacity makes them ideal for applications requiring consistent energy without excessive weight. For marine environments, they’re frequently used in trolling motors and onboard electronics. Below are specific vehicle models known to use Group 24 batteries:
| Vehicle Type | Models |
|---|---|
| Compact Cars | Toyota Corolla (2010-2015), Subaru Impreza |
| Motorcycles | Harley-Davidson Street 750, Kawasaki Vulcan S |
| Marine | Tracker Pro Team 175, Lund 1600 Rebel |
Hybrid vehicles with smaller engines may also employ Group 24 batteries for secondary systems. Always confirm terminal orientation and voltage requirements before installation.
Expert Views
“Battery Group 24 remains a cornerstone for compact automotive systems due to its balance of size and output. However, advancements in lithium-ion technology are challenging traditional lead-acid designs. We recommend consumers prioritize RC (reserve capacity) over CCA alone for modern electronics-heavy vehicles.” — Industry Expert, PowerSource Battery Technologies
Conclusion
Understanding Battery Group Code 24 ensures proper vehicle operation and longevity. From compatibility checks to maintenance practices, selecting the right battery involves balancing technical specifications with real-world usage demands. As battery technology evolves, staying informed about emerging alternatives will become increasingly critical for optimal performance.
