What Does “31” Mean on a Battery?
The “31” designation on a battery refers to a specific size classification defined by the Battery Council International (BCI). This classification helps standardize battery dimensions and performance characteristics, ensuring compatibility across various applications. A Group 31 battery typically measures approximately 13 x 6.8 x 9.4 inches and is commonly used in marine, RV, and heavy-duty applications.
What Is a Group 31 Battery and Its Designation?
A Group 31 battery is part of a standardized classification system established by the BCI that specifies battery dimensions, terminal placement, and performance characteristics. The number “31” identifies this particular group size, which is designed for heavy-duty applications requiring reliable power.
Key Specifications:
- Dimensions: Approximately 13 inches (330 mm) in length, 6.8 inches (173 mm) in width, and 9.4 inches (240 mm) in height.
- Weight: Typically ranges from 50 to 70 pounds.
- Capacity: Generally offers capacities from 100 to130 amp-hours (Ah).
| Specification | Value |
|---|---|
| Length | ~13 inches |
| Width | ~6.8 inches |
| Height | ~9.4 inches |
| Weight | ~50 -70 pounds |
| Capacity | ~100 -130 Ah |
How Does the “Group” Classification Work in Battery Sizes?
The “group” classification system helps consumers easily identify batteries that will fit their specific needs based on size and performance. Each group number corresponds to specific dimensions and electrical specifications, ensuring that batteries can be interchanged without compatibility issues.
Example of Other Groups:
- Group 24: Measures approximately 10.25 x 6.81 x 8.87 inches, typically used in smaller vehicles.
- Group 27: Measures around 12 x 6.75 x 9 inches, suitable for moderate power needs.
This standardization aids in selecting the right battery for various applications.
| Battery Type | Length (inches) | Width (inches) | Height (inches) |
|---|---|---|---|
| Group 24 | ~10.25 | ~6.81 | ~8.87 |
| Group 27 | ~12 | ~6.75 | ~9 |
| Group 31 | ~13 | ~6.8 | ~9.4 |
What Are the Dimensions and Specifications of a Group 31 Battery?
The dimensions of a Group 31 battery are standardized to ensure compatibility with various applications:
- Length: Approximately 13 inches
- Width: Approximately 6.8 inches
- Height: Approximately 9.4 inches
These dimensions make it suitable for installations where space is limited but high capacity is required.
What Are the Key Features of Group 31 Batteries?
Group 31 batteries are designed with several key features that make them ideal for demanding applications:
- High Capacity: Typically provides between 100 to130 Ah, allowing for extended use without recharging.
- Durability: Built to withstand harsh environments, making them reliable for marine and industrial use.
