Group 31 generally stores more energy than a group 24 or 27. Generally the higher the group the better the battery. Not all 100ah batteries are created equal. If group 24 and group 31 were the exact specifications, they would not build them for the simple reason that the larger case costs more, and takes up more room when shipping meaning higher mfg. and shipping costs. Imagine how many more group 24 batteries you could get in a container compared to group 31 batteries.
You'll find detailed info on
group 31 battery dimensions, features, and recommendations in the linked article. However, I'll provide a brief overview of what the term "Group 31" means on a battery, its dimensions, and its primary characteristics below.
The term "Group 31" refers to a specific classification in the Battery Council International (BCI) system, which categorizes batteries by their physical size, terminal placement, and other technical specifications. Therefore, a Group 31 battery is a battery that meets the specifications set out for this category.
The dimensions of a standard Group 31 battery typically measure approximately 13 inches in length, 6.72 inches in width, and 9.44 inches in height. However, slight variations may occur depending on the manufacturer.
Group 31 batteries are widely known for their high capacity and resilience, making them highly suitable for heavy-duty applications. Here are some of their key features:
- High Capacity: Group 31 batteries generally have a high power capacity, making them ideal for vehicles and machinery that require a substantial amount of power.
- Deep Cycle Capability: Many Group 31 batteries are designed for deep cycling, making them suitable for applications like solar energy storage or powering trolling motors where frequent charging and discharging are needed.
- Vibration Resistance: These batteries are often built with a robust case and robust internal components that can withstand significant amounts of vibration, making them ideal for heavy-duty vehicular use.
- Maintenance-free: Most Group 31 batteries available today are sealed, lead-acid batteries, which are virtually maintenance-free. This makes them a convenient choice for many applications.
Overall, the Group 31 classification on a battery refers to the BCI's specific physical and technical parameters. Batteries in this category are known for their large size, high capacity, and resilience, making them a favored choice for heavy-duty, high-power-demand applications.
