24f vs 35 Battery, What Is the Difference?

Do you know the difference between 24F and 35 battery? If not, you’re not alone. A lot of people don’t know the difference or what those numbers even mean. But it’s important to understand the difference so you can make an informed decision when it comes time to buy a battery. In this blog post, we’ll break down everything you need to know about 24F and 35 batteries so you can choose the right one for your needs. Stay tuned!

What is the difference between battery size 24F and 35?

The distinctions between Group 24F and Group 35 batteries are very minor. But knowing their differences can help you when it comes time to choose the perfect battery for your needs. The three sections below will give you a better understanding of these two battery types.

Physical Size and Weight:

The physical size of Group 24F battery is typically longer than that of a Group 35 battery. This makes the Group 35 battery an ideal option for applications where space is limited, such as in motorcycles or small boats.

The weight of a Group 24F battery is also typically heavier than that of a Group 35 battery. This difference in weight may be important if you are looking for a lightweight battery to save on overall transportation costs.

CCA Rating:

The cold-cranking amps (CCA) rating is the measure of a battery’s ability to start an engine in cold weather. A Group 24F battery will typically have a higher CCA rating than a Group 35 battery. This may be important if you live in a colder climate or use your vehicle in extreme weather conditions.

When it comes to changing your battery, it is always recommended to choose the same group size that is already in your vehicle. This way, you can ensure that you are getting a battery that is compatible with the electrical system and will not require any additional modifications. Should you decide to choose a battery that is a different CCA rating than what is already in your vehicle, it is important to consult with an automotive technician to ensure that the change will be safe and effective.

Reserve Capacity:

The reserve capacity (RC) of a battery is the amount of time that the battery will continue to provide power after it has been fully discharged. A Group 24F battery typically has a higher RC rating than a Group 35 battery. This may be important if you need a battery that can provide backup power for an extended period of time.

In addition to the above categories, Group 24F batteries are typically used in light-duty applications such as small cars, motorcycles, and boats. Group 35 batteries are more commonly used in heavy-duty applications such as large trucks, construction equipment, and boats.

Choosing the right battery for your needs can be tricky. But with a little bit of knowledge about the different types of batteries available, you will be able to make an informed decision that fits your specific needs.

What does 35 mean on a battery?

When you see 35 on a battery, it means that the battery is rated for 35 amps. This rating is important because it tells you how much current the battery can provide. A higher amp rating means that the battery can provide more power and is better suited for high-demand applications.

Group 35 batteries are often found in cars from the early to mid-1990s. They may be common as other batteries, but you can still find them if you look for them. These batteries are commonly found in Japanese and American cars.

Group 35 batteries are also best used in applications that require a high amount of power, such as starting large engines or running multiple electrical devices. If you need a battery for a boat, RV, or tractor, then you’ll want to choose a group 35 battery. Just make sure that it will fit in the space you have available.

Can you use a Group 35 battery in a car instead of Group 24F?

Yes, you can use a Group 35 battery in a car instead of Group 24F. However, it’s important to make sure that the battery is compatible with the vehicle’s electrical system. Also, make sure that it fits the battery compartment. Group 35 batteries are typically shorter than Group 24F batteries. A car battery should be installed perfectly to avoid vibration, sparks, and leakage. If the car is moving and the battery is shaking, it could cause a dangerous situation.

In addition, Group 35 batteries are typically used in commercial vehicles, so check with your vehicle manufacturer to make sure that it will work correctly.

What does 24F mean on a car battery?

Car battery size refers to the physical dimensions of the battery. The Battery Council International standardized battery sizes so that consumers could easily compare and purchase the correct battery. The first two numbers indicate the group size, and the F stands for the degree of measurement of energy in the battery.

The group size is important because it determines how much current a battery can deliver. Batteries with a higher group size will be able to deliver more current than those with a lower group size. The most common sizes are 24F, 27, 31, 34, and 78.

The 24F battery is a great choice for drivers who are looking for an affordable, high-quality option. It offers superior performance and longer life than traditional lead-acid batteries, making it the perfect choice for drivers who are looking to save money on gas and reduce their environmental impact.


When it comes to choosing a battery, the most important thing to consider is your individual needs. The distinctions between Group 24F and Group 35 batteries are minor, but knowing their differences can help you make the best decision for your specific application. You can always check with a battery specialist to make sure you’re getting the right battery for your needs.

As always, choosing the same brand of battery for your vehicle will give you the best performance. Should you wish to get a different brand, always use the compatible type, which is usually written on the battery.
