Group 24 batteries are highly sought-after, and selecting the right manufacturer and design for your needs can be overwhelming. This can be especially daunting if you’re new to working with larger cells found in vehicles and watercraft.
So, what exactly does “group size” refer to, and why are group 24 batteries so popular? Let’s take a closer look to find out.
Understanding Battery Group Sizes
Batteries come in a wide range of shapes and sizes, but what exactly does it mean when we refer to a battery “group”? In essence, the term “group” refers to the size classification of automotive batteries.
In the battery industry, “group size” refers to the specific physical characteristics of a battery that make it the best fit for a particular vehicle in terms of size, performance, and terminal placement.
The group size of the batteries in your car can usually be found on the label of the current batteries or in the instruction booklet. While many vehicles can accommodate different group sizes without compromising battery performance, it’s always crucial to choose an appropriate one.
Is Battery Group Size Important for Batteries?
There is a misconception that replacing a Group 24 battery with larger group cells will increase its capacity. However, it’s important to note that battery group size and capacity are not directly linked. Many people are unaware that automotive batteries come in various types and are not interchangeable.
The size of an automotive battery does matter. It significantly impacts the performance of your vehicle. The power requirements for starting the engine vary depending on the size of the vehicle, whether it’s a large work tractor or a smaller car.
Choosing a battery size that is either too small or too large and doesn’t match the power requirements of your vehicle can lead to various issues and adversely affect its performance.
Understanding Group 24 Batteries
Group 24 batteries are a specific size of battery commonly used in automobiles, backup generator systems, and medical instruments. Unlike their usage in engine power, Group 24 batteries are typically employed as rechargeable batteries in various applications.
Advantages of Group 24 Batteries
Group 24 batteries offer several benefits due to their adaptable size, making them suitable for various applications. Whether it’s for camper vans, boats, or any other portable power source, these deep-cycle batteries provide a reliable and sustained electricity supply.
Compared to larger 100Ah batteries, Group 24 batteries are slightly smaller and more compact. This makes them ideal for specific locations or purposes that do not require an extensive amount of power. Additionally, their compact size allows for easy fitting in a wide range of spaces.
Dimensions of Group 24 Batteries
The standard dimensions for a Group 24 battery are approximately 10.5″ in length, 6.1875″ in width, and 8.875″ in height. However, within the Group 24 battery size category, there are several subgroups with different measurements. These subgroups are labeled as 24F, 24H, 24R, and 24T.
While the actual sizes of battery compartments are generally similar, it is important to consider these small differences when selecting the appropriate fully-automatic and worry-free battery charger.
| BCI Group Size | L x W x H (mm) | L x W x H (inches) |
| 24 | 260 x 173 x 225 | 10 1/4 x 6 13/16 x 8 7/8 |
| 24H | 260 x 173 x 238 | 10 1/4 x 6 13/16 x 9 3/8 |
| 24F | 273 x 173 x 229 | 10 3/4 x 6 13/16 x 9 |
| 24T | 260 x 173 x 248 | 10 1/4 x 6 13/16 x 9 3/4 |
| 24R | 260 x 173 x 229 | 10 1/4 x 6 13/16 x 9 |
Common Specifications of Group 24 Batteries
When purchasing Group 24 deep cycle batteries, it is essential to consider your specific requirements rather than making an impulsive decision at the store.
The most commonly found type of Group 24 battery is the AGM (Absorbent Glass Mat) SLA (Sealed Lead Acid) battery. However, other types and chemistries are also available, such as gel-cell batteries, flooded batteries, and even battery packs.
While these batteries share similarities, it’s important to note that the BCI Group 24F is larger and longer compared to other groups.
In terms of capacity, Group 24 batteries typically range from 135 minutes of energy storage (RC – Reserve Capacity) to 160 RC, 500 Cold Cranking Amps (CCA) to 850 CCA, and 70 Ampere-hours (Ah) to 85 Ah. These specifications may vary depending on whether the battery is a thick panel deep cycle battery, flat plate stop/start battery, or a hybrid variant.
Are Group 24 Lithium Battery Designs Available on the Market?
Absolutely! There are various options available, including the Battle Born Group 24 Cells, for those seeking a Group 24-compatible battery but are interested in transitioning to a lead-acid and lithium-ion battery. These batteries come in both 50Ah and 75Ah versions, providing users with flexibility and choice.
Drawbacks of Group 24 Batteries
Group 24 batteries, like other deep-cycle batteries, have both advantages and disadvantages due to their specific size. One drawback is that they typically have a shorter lifespan compared to larger capacity batteries. However, they make up for this by being more cost-effective. Their smaller size allows for greater flexibility in terms of installation and fitting into various spaces.
What Vehicles Utilize Group 24 Batteries?
Group 24 batteries are commonly used in automobiles that require an additional power source beyond their standard starting battery. This includes trucks, vans, and commercial vehicles, where they serve as auxiliary battery systems.
These batteries are also found in watercraft that operate in a similar manner. Group 24 batteries are often utilized to power boat trolling engines for activities such as kayaking, fishing, or leisurely sailing.
What Factors to Consider Before Purchasing Group 24 Batteries?
Before investing in a group 24 battery, it is essential to consider the following factors:
Durability: The durability of the battery should be a top priority. It should be made of high-quality components to ensure long-lasting performance and reliability.
Quality: Assess the features and quality of the group 24 deep cycle battery before making a purchase. Even if a battery has all the desired features, a low-quality build can diminish its value.
Affordable Price: Consider the price of the battery and compare it to your budget. Look for the best group 24 battery that offers a balance between quality and affordability.
Customer Reviews: Reading online reviews from customers can provide valuable insights into a product’s performance and reliability. Platforms like Amazon often have customer reviews that can help you make an informed decision before buying.
