The Comprehensive Guide to Group 24 Batteries

Group 24 batteries are automotive lead-acid batteries that are typically utilized in heavy vehicles such as trucks, RVs, agricultural machinery, and similar heavy-duty applications. Their designation as “Group 24” indicates that they conform to a standardized size determined by the Battery Council International. This article will delve into the details of what defines Group 24 batteries and why they are favored for providing power to larger vehicles.

What is Group Size?

The group size of a battery refers to its standardized physical dimensions that are assigned by the Battery Council International (BCI). There are several common group size designations for lead-acid automotive starter batteries:

• Group 24 - A large battery commonly used in heavy-duty vehicles like trucks. It has dimensions of about 10" x 7" x 9".
• Group 27 - An even larger battery used for commercial vehicles and trucks. Approximately 12" x 7" x 9" in size.
• Group 35 - A mid-sized battery used in many passenger cars. Around 10" x 7" x 7" in dimensions.
• Group 51R - A small battery for compact cars and some motorcycles. Common dimensions of 5" x 5" x 4".
• Group 65 - A large battery used in performance cars, trucks, or diesel vehicles. Approximately 12" x 6" x 9" in size.

Everything You Need to Know about Group 24 Battery

Specs and Technical Details

Traditional group 24 lead-acid batteries have the following specifications:

• Voltage: 12V
• Capacity: 50-100 Ah
• Dimensions: 10" x 6 7/8" x 8 15/16"
• Terminal type: SAE / GM posts
• Average weight: 50-60 lbs

The high CCA provides the power to start diesel engines. The size offers the capacity to run accessories.

However, lithium batteries are gaining popularity due to their benefits, take GrenerPower 12V100Ah Group 24 LiFePO4 lithium battery for example:

• Voltage: 12V
• Capacity: 100 Ah 
• Dimensions: Identical to group 24
• Terminals: Compatible with lead-acid
• Average weight: Only 21 lbs

While lead-acid group 24 batteries are a trusted solution, lithium is an increasingly attractive upgrade for maximum power-to-weight and reduced long-term costs.

Applications and Vehicle Compatibility

Group 24 batteries are most commonly found in:

• Heavy-duty trucks like semi-trucks and dump trucks
• RV motorhomes
• Buses
• Commercial work vans
• Agricultural equipment Diesel pickup trucks

Advantages of Group 24 Batteries

Group 24 batteries offer numerous advantages for automotive and marine use. They have a higher capacity, allowing for longer run times before needing recharge. They also provide sufficient power output for engine starting efficiency. These batteries are compact and easy to install in tight spaces. They are built to withstand tough environments and extreme temperatures.

Many Group 24 batteries are maintenance-free, eliminating the need for regular upkeep. Moreover, they are easily accessible, making them convenient to replace or upgrade when necessary.

In summary, Group 24 batteries offer a well-rounded combination of power, size, and durability, making them a popular choice for automotive and marine applications.
