What is A Group 24 Battery? Dimensions and Features

Group 24 battery is a popular choice for a wide range of applications, from automotive and marine use to renewable energy systems. In this article, we’ll explore the key aspects of Group 24 batteries dimensions, features, sizes, and maintenance, helping you determine if it's the right fit for your needs.

What Does Group Size Mean on A Battery?

Group size is a standardized classification system that denotes a battery's physical dimensions and terminal location, determining its compatibility with specific vehicles or equipment. This industry-wide code, established by organizations like the Battery Council International (BCI) for automotive and marine batteries, ensures compatibility and interchangeability among batteries from different manufacturers. Ultimately, understanding battery group sizes is crucial for selecting the right battery to power various devices.

What is A Group 24 Battery?

BCI Group 24 battery has a wide range of applications, including large UPS systems, medical and security systems, wheelchairs, vehicles, and industrial equipment. However, they are not commonly used as starting batteries but are more frequently utilized in deep cycle standby or float applications.

Group 24 battery is one of the most prevalent battery group sizes in the market, with the commonly used chemistry being AGM (Absorbent Glass Mat) SLA (Sealed Lead Acid) batteries. However, other chemistries/types such as gel-cell batteries, flooded batteries, and even lithium-ion batteries are also available within this group.

The Dimensions of Group 24 Battery

BCI Group 24 batteries have specific dimensions that are generally 10.25 x 6.8125 x 8.875 inches (260 x 173 x 225 mm). 

However, it is important to note that within the Group 24 category, there are various subgroups with slight variations in dimensions. When selecting a battery, precision is necessary to ensure it fits properly into its designated compartment. Even minor size differences can result in a battery not fitting correctly.

Here is the chart of common battery sizes:

In many cases, battery compartments have enough extra height to accommodate a Group 24 battery, which has a height of 8 7/8 inches. This means that they can generally also accommodate batteries from the Group 24T category, which have a height of 9 3/4 inches. The Group 24T battery is only 7/8 inches (or 0.875 inches, approximately 22 mm) taller than the standard Group 24 battery. 

Group 24 Battery VS Other Battery Groups Size

Battery compartments designed for Group 24 batteries may also be compatible with Group 34 batteries, as they have the same length and width but are one inch shorter in height. Additionally, Group 25/35 batteries have the same height of 8.875 inches (22.5 cm) as Group 24 batteries.

While they may be slightly shorter (~1.2 inches or 3 cm), they are also slightly wider by 0.0625 inches (0.16 cm). However, this width difference is so small that it can be practically ignored.

Features of a Group 24 Battery

Group 24 batteries come with a variety of features that make them suitable for different applications. Some of the key features include:

1. High Capacity and Performance

Group 24 battery offers a substantial capacity, typically ranging from 70 to 85 amp-hours (Ah). This makes it ideal for applications that require sustained power over a longer period, such as RVs, boats, and backup power systems.

2. Durability and Longevity

These batteries are designed to withstand harsh conditions and frequent cycling. Lithium-ion versions are particularly known for their durability and long lifespan, as they are less prone to damage from vibration and deep discharges compared to flooded lead-acid batteries.

3. Versatility

Group 24 batteries are versatile and can be used in various applications, including automotive, marine, RVs, solar power systems, and backup power. Their standardized size and capacity make them a go-to choice for many different uses.

4. Safety Features

Many Group 24 batteries come equipped with safety features such as spill-proof designs, low self-discharge rates, and built-in protection against overcharging and short circuits. These features enhance the safety and reliability of the batteries.

Can Group Sizes Be Used Interchangeably?

Group sizes cannot be used interchangeably without careful consideration. While some group sizes may have similar dimensions, variations in height, width, and length can impact compatibility with battery compartments or connections. It's essential to choose a battery that matches the specifications and requirements of your device or vehicle to ensure optimal performance and safety.

How Much Does a Group 24 Battery Weigh?

On average, a Group 24 battery weighs between 40 to 50 pounds (18 to 23 kg). AGM and gel versions might be heavier due to their construction and materials. For example, Redodo Group 24 LiFePO4 Battery weights only 21.6lbs, 2/3 lighter than the same capacity of AGM battery.

Upgrade to Group 24 Lithium Battery

Battery technology has significantly evolved over the years, and one of the latest and most popular advancements is the Group 24 Lithium Battery.

This type of battery offers numerous advantages over traditional lead-acid batteries, including enhanced performance, longer lifespan, and minimal maintenance requirements.
