24F Vs. 35 Battery: Detailed Comparison

We all have heard how significant the battery group number is at this point of owning wheelers. It is not only the battery type but also the battery size that matters. If you don’t get the right fit for your car, how is it going to work?

Among different group size batteries, 24F and 35 are the most common ones. That indeed creates a “24F vs 35 battery” debate situation. Both of the batteries have a lot of user fan bases. 

A 24F group size battery is a subgroup of 24. Group 24 also has 24H, 24R, 24T and 25. Group 35 is an individual group size battery. So, let’s dive in and figure out more differences between 24F and 35 group size batteries.

In-depth discussion – 24F vs. 35 Battery

From the comparison chart above, you can quickly view the differences between 24F and 35 group size batteries. Now, let’s know about the specification in detail.

Dimension difference

The BCI numbers, previously called the group size number, are a practical measure of the battery. The Battery Council International sets it. They set the numbers of each battery by its structural specification.

24F batteries have a dimension of 10.3*6.8*8.9. It says about the length, width and height of the battery. On the other hand, the 35 group size battery has a dimension of 9.1*6.9*8.9. So, you can see the 24F is a larger battery than 35. 

Besides the size difference, there is a weight difference too between them. The larger battery, 24F, is heavier by 4lbs or around 35 batteries. As the battery is more extensive, it has more components to make it more weight.

The terminal position is identical in both of the batteries. You will find top terminal options in them. So, you don’t need to bear the hassle to connect the battery with your car.

Cold Cranking Amps and Reverse Capacity

You can see a clear CCA and RC rating difference between the batteries. 24F has a higher Cold Cranking Amps than 35. Generally, CCA refers to the number of amps delivered in 30 seconds at 0 degrees where height.

To better understand general people, CCA takes care of your car in cold temperatures. To be specified, a battery with a higher CCA will last longer than a lower one. Also, higher CCA will prevent the battery from cold weather and make it work through. So, you can see the 24F BCI number battery is more durable and resistant to cold temperatures.

Now, let’s talk about reserve capacity. Well, batteries do not have any function to store or reserve any power. But the reserve capacity means the number of minutes that a battery can deliver 25 Amps at 80 degrees Fahrenheit. A 24F battery has an RC rating of 160 minutes, and a 35 battery has an RC rating of 130 minutes. 

Usage of the batteries

24F batteries are primarily used in different cars like Nissan, Honda, Acura and Toyota. These batteries are also used for general purposes like in an extensive UPS system. You can see the use of 24F batteries in a deep cycle and stand by applications. 

Lead-acid and AGM batteries both are popular in 35 group size batteries. They are used in Cars, Trucks and RVs. These batteries are also used in UPS, wheelchairs and different security systems. Nowadays, you can also get some lithium-ion batteries in 35 group size batteries. 

Replacement in between

You already know that 24F is a larger battery than 35. So, if you are already using a 24F battery, you can replace it with a 35 battery. It would not require any cutting or alterations to your existing battery tray.

But if you are using a 35 battery and want to shift to a 24F battery, check if the existing battery shows any space in the battery tray. If it does, maybe you can fit in the 24F as a replacement. If it doesn’t, you need to make some changes to the space in the battery tray.

Cost comparison

The 35 group size battery is somehow costlier than the 24F group size battery. You can also find better batteries in the 24F group at a similar price.

24F or 35 Battery – Which one to choose?

Investing in a new battery is already a huge decision. Because you are going to consume it for a minimum of 4 years from the installation, it must be a good choice taken sincerely. 

Choosing between 24F and 35 group size batteries is not so difficult. Yet you need to keep something in your mind. Firstly, figure out what you want. If you live in a colder area, you need a battery with excellent CCA. As far we know, 24F has higher CCA, it can be an excellent choice for you,

If you drive in a less cold or hot area, you don’t need a lot of CCA. But still, you need a good one to go. So, 35 group size batteries could be okay for you. Again, consider the budget. If you can get a better battery at a lower price, why not go for it? 


Which battery is better, 24F or 35?

Both 24F and 35 batteries are good. But 24F is better in COLD Cranking Amps. 

What is battery group size 35?

Battery group size 35 refers to a BCI number. That says about the physical dimension of a battery. This battery is standard-sized and is used commonly in vehicles.

What cars take a 35 battery?

35 batteries are used in different brand cars, trucks and SUVs. 

Are 24 and 24F batteries the same?

24F is a subgroup size battery of the 24 groups. They may seem the same, but 24F is a larger battery than the 24 battery. Also, the height of the batteries is nearly identical but different.

What cars take a 24F battery?

Nissan, Honda, Toyota and other brands’ cars take 24F batteries.

Final Words

Now, we have come to the end of the discussion of 24F vs 35 batteries. Hope that this article gives you a vivid idea of both of the batteries. Now you can choose one between them to install in your car.
