What Is the Difference Between 24 and 27 Marine Batteries?

Group 24 and Group 27 marine batteries are popular choices for boaters, but they serve different needs based on their specifications. Generally, Group 27 batteries provide more capacity and power compared to Group 24 batteries, making them better suited for larger applications. Understanding these differences is crucial for selecting the right battery for your marine needs.

What Are Group 24 and Group 27 Marine Batteries?

Group 24 and Group 27 batteries are standardized sizes defined by the Battery Council International (BCI). They are commonly used in marine applications due to their reliability:

• 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 27: Larger, measuring approximately 12.5 inches long, 6.75 inches wide, and 9.37 inches high, with a capacity of about 85-100 amp-hours.

How Do Their Sizes Compare?

The primary difference in size between the two groups is that the Group 27 battery is larger in both length and height compared to the Group 24 battery:

• The increased size of Group 27 allows for more internal space, which translates to higher capacity.
• This additional capacity makes Group 27 batteries better suited for applications requiring sustained power over longer periods.
