Is a Group 31 Battery Better Than a Group 24?

When comparing Group 31 and Group 24 batteries, it’s essential to understand their specifications, applications, and performance characteristics. Generally, Group 31 batteries offer higher capacity and longer runtimes compared to Group 24 batteries, making them suitable for more demanding applications. This guide will help you determine which battery type is better suited for your needs.

What Are Group 31 and Group 24 Batteries?

Group 31 and Group 24 batteries are standardized sizes defined by the Battery Council International (BCI). They are commonly used in marine and automotive applications:

• Group 24: Typically measures about 10.25 inches long, 6.75 inches wide, and 8.875 inches high, with a capacity of around 70-85 amp-hours.
• Group 31: Larger, measuring approximately 12.9 inches long, 6.8 inches wide, and 9.4 inches high, with a capacity of about 100-130 amp-hours.
