What is A Group 24 Battery? Dimension and Features

If you're not familiar with dealing with larger batteries like the ones found in RVs and boats, it can be overwhelming. You may find yourself having to consider various factors, such as style, capacity, voltage, and the battery's group size. But what does group size actually refer to? And why is it common for boaters and RVers to encounter Group 24 batteries? Let's dig deeper into these questions.

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 Group 24 Batteries

BCI Group 24 batteries have 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.

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.

One of the most prevalent battery group sizes in the market is BCI Group 24. This group encompasses various types of batteries, 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.

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's important to note that there may be subgroups or variations within this size category as well.

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 Batteries 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.

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 to Maintain Group 24 Battery

Maintaining a Group 24 battery is crucial for ensuring its longevity and optimal performance. Here are some essential tips to help you maintain your Group 24 battery:

Keep it clean: Regularly inspect the battery terminals and cables for signs of corrosion or buildup. If you notice any, clean them with a mixture of baking soda and water. Use a wire brush to scrub off the corrosion, rinse with clean water, and dry the terminals thoroughly.

Check the electrolyte level: If your battery has removable caps, regularly check the electrolyte level. Ensure it is above the plates and add distilled water if needed. Avoid overfilling the battery.

Avoid deep discharges: Group 24 batteries perform best when they are not deeply discharged. Try to keep the battery charged above 50% to increase its lifespan. Consider using a battery maintainer or charger if the battery discharges frequently to keep it topped up.

Charge properly: When charging the battery, make sure you use a compatible charger that matches the battery's voltage and charging requirements. Follow the manufacturer's instructions and avoid overcharging the battery.

Store in a cool, dry place: If you need to store the battery for an extended period, find a cool and dry location. Extreme temperatures can negatively affect the battery's performance and lifespan.

Perform regular inspections: Check the battery for any physical damage, leaks, or signs of wear. If you notice any issues, it may be necessary to replace the battery.

Remember, specific maintenance requirements may vary depending on the manufacturer's recommendations and the battery type. Always consult the battery's manual or contact the manufacturer for specific maintenance instructions.
