The two most prevalent and well-liked battery sizes that we encounter in RVs, watercraft, backup power systems, and medical devices are group 24 and group 27 batteries. includes vehicles such vacation trailers, boats, and RVs. But how do group 24 and group 27 batteries differ from one another? Some of these variations will be covered in this post so you can be certain you’re choosing the appropriate battery for your automobile or truck.
Group 24 battery
Standard model Group 24 batteries have dimensions of 10.5′′L x 6.1875′′W x 8.875′′H. a particular battery size that is frequently used in cars, backup power systems, and medical equipment. Instead of starting the engine, Group 24 batteries are frequently employed as deep cycle batteries.
Group 27 battery
Generally speaking, the group 27 battery, which has dimensions of 12.5′′L x 6.75′′W x 9.37′′H, is likewise a typical model. A particular size of battery that is frequently used for backup power systems, off-the-grid RVs, automotive, marine, and related applications. it exceeds group 24 batteries in size. In general, bigger group sizes have more amp hours than smaller values.
Group 24 vs 27 Deep Cycle Batteries, What Are The Differences?
Lead-acid battery banks may employ both Group 24 and Group 27 deep cycle batteries. Although their performance requirements are comparable, they differ in some significant ways.
Depending on the kind of vehicle you need it for, Group 24 batteries’ smaller size, lower power capacity, and lower weight can be a game-changer. You would believe that the larger the battery, the better, but on a yacht with a weight restriction, excess weight might be hazardous. You should be aware that making a sensible decision now might end up saving you a lot of money later.
Generally speaking, the group 24 battery’s applications are as follows:
Large UPS systems for backup power Applications for wheelchairs in the medical, security, and industrial fields In addition to this, you may observe its use as a cranking or starting battery.
However, the group 27 battery is also used in off-grid, RV, automotive, marine, and other related applications.
The most popular BCI Group battery chemistries, regardless of whether they are group 24 batteries or group 27 batteries, are and Sealed Lead Acid (SLA).
- AGM (AGM) Absorbent Glass Mat Batteries
- Lead Acid Sealed (SLA) Batteries
- Lithium-ion batteries
- Gel cell batteries
- Flooded batteries
Lead-acid batteries are the most affordable among them, but lithium batteries have a long cycle life and have drawn a lot of consumers’ attention due to their environmental friendliness and capacity to be recycled.
Weight and physical dimensions
The dimensions of a group 24 battery are around 11 inches long, 7 inches wide, and 9.5 inches high. Marine batteries in the Group 24 family generally weigh between 40 and 50 pounds.
The dimensions of Group 27 are generally 12 x 7 x 9 inches (300 x 170 x 225 mm). These batteries often weigh 60 to 75 pounds.
Even though there isn’t much of a difference between these batteries, on sometimes a few millimetres can make a difference in whether the battery fits in the battery slot. Before buying a new battery, measure the size of your engine compartment as most manufacturers mark their batteries with dimensions (both in inches and millimetres).
If you’re looking for a deep cycle battery, you might be thinking which group battery is appropriate for your requirements. There are numerous possibilities available, however Group 24 and Group 27 batteries differ significantly in terms of price: Group 27 batteries are more costly.
A new battery with group 24 costs between $50 and $100, whereas a battery with group 27 might cost as much as $300. They are more capable per weight and have a higher CCA than Group 24. This makes them perfect for heavy-duty and long-lasting applications like electric and golf carts.
Group 27 batteries have a little higher capacity than group 24 batteries. Any group size with a higher number often contains more amp hours than groups with smaller values.
Pros and Cons of Group 24 and Group 27
What battery is superior? Of course, the response varies depending on the various application cases. To be sure you are getting great service for your investment, you must first understand how batteries are classified and how they operate.
The group 27 battery has a greater output current than the group 24 battery. Therefore, group 27 batteries are designed for large commercial and industrial machinery. As a result of their increased capacity, they also produce more power and last longer. The group 27 battery can be the solution if you’re seeking for a battery that offers the best long-term performance for years to come.
Because group 24 batteries are now found in the majority of autos, most people are familiar with them. Batteries of group 24 should not be used in high current applications. However, certain versions have CCA and MCA (Marine Cranking Amps) ratings of 500–840 amps and 625–100 amps, respectively, allowing them to be used as starting batteries for small petrol or diesel engines. They may be utilised in tiny machines that don’t need a lot of power, such snowmobiles or motorbikes.
