In the future, the time will come when you need to replace your vehicle’s battery. If you own a medium-sized SUV such as a Toyota RAV 4, the manufacturer’s battery installed in the car will be a Group 24F model.
However, you may be surprised to find out that when it comes to replacing the battery in your car, you don’t need to go like for like. You could replace it with one from another battery group. Therefore, we look at the Group 24F battery vs. Group 35 battery.
Before you go out and spend cash on replacing your current car battery with a new one, you need to be aware of certain things, all of which will help you make a more informed decision about which battery is best for your vehicle.
As well as looking at the key differences that you’ll find between the Group 24F battery and the Group 35 battery. We will also look at whether it is a good idea to install a more powerful battery in your car.
Finally, we will then provide you with a few batteries that we would consider worth buying to replace the one you currently have in your vehicle.
What Is The Difference Between Group 24F and Group 35 Batteries?
The differences, as you will soon see between these two groups of batteries, are pretty minimal. So it would be best if you still were careful about which one you choose to buy.
#1 Difference: Physical Appearance
Dimensions
With these two batteries, the difference in size is relatively minute. Group 24F batteries measure 10.3 x 6.8 x 8.9, whereas the Group 35 batteries measure 9.1 x 6.9 x 8.9.
Immediately you can see that the 24F battery is that bit longer than the Group 35 battery. So if you were to buy a Group 35 battery, you might need to make some adjustments to the battery box to ensure that it cannot move around.
Weight
Although the Group 24F battery is only around an inch longer than the Group 35 battery, it weighs more. A Group 24F battery weighs around 4 lbs more than the Group 35 battery does.
Terminal Positions
The terminal arrangement for these batteries appears to be the same, meaning that the positive terminal is on the right-hand side of the battery.
If you consider replacing a Group 35 with a Group 24F, you will need to either alter the battery box already fitted in your vehicle or replace it.

#2 Difference: CCA Rating
The first actual difference between the Group 24F battery vs. Group 35 battery is the CCA rating. 24F batteries have a much higher CCA rating compared to the 35 batteries.
It is vital that when you are replacing the battery in your car, you go for one that has the same or a slightly higher CCA rating than the one in it now. It will ensure that you will not have any problems with you starting your car.
Also, think about where you live. If you live somewhere that gets cold, you need a battery with a high CCA rating. So it would be advisable to say a Group 24F battery with an 840 CCA rating. It will help ensure that the battery has enough power to help get your car’s engine started.
#3 Difference: RC Rating/Ah Rating
The third difference between these two batteries is that the 24F comes with a higher RC rating. The highest rating for a Group 24F battery is 160 minutes, whereas, for a Group 35 battery, it only has an RC rating of 130 minutes.
You must be aware that both the RC rating and Ah rating on a battery are essential as part of the battery’s deep cycling feature. The only difference between them is that Ah = (RC: 2) + 16.
Can You Put A More Powerful Battery In Your Car?
You can replace a Group 35 battery in your car with a Group 24F one if you want to. But before doing this, you need to look closely at the size of the battery box in which the battery will sit.
As the Group 24F battery is slightly longer than the Group 35, you may need to make alterations to the battery box to get it in. The other thing you could do is choose to replace the battery box altogether with one specifically designed for a Group 24F battery to sit in.
Only consider replacing the battery box if you intend to continue using a Group 24F battery from now on in your vehicle.
