When replacing the battery in your car, you will often choose to go with the same make and model. However, sometimes it may be worth considering choosing a different group battery altogether.
Below we look at a Group 24 vs. 34 battery and why you should consider each one for your vehicle.
This will help ensure that you choose the right one to provide you with all the power that your car’s engine and electronics need.
Group 24 vs. 34 Battery: 4 Differences To Consider Before Replacing Your Battery?
One of the first things to note is that Group 34 batteries are much more common than the Group 24 models for use in vehicles such as cars, SUVs, and trucks. More often, you’ll find that Group 24 batteries are the kind of battery that will be used in motorboats, speed boats, and jet skis.
When it comes to replacing the old battery in your car with a new one, you need to make sure that the new one is the same as the old one. However, when it comes to deciding to go with a battery from a different group, there are certain things you need to consider.
The main features that you need to look at closely, especially if you are thinking of replacing a Group 24 battery with a Group 34 battery, are as follows.
#1 Difference: Physical Size – Dimensions
- Group 24: 10.3 x 6.8 x 8.9 (inches)
- Group 34: 10.3 x 6.8 x 7.9 (inches)
There isn’t that much difference in their dimensions when it comes to Group 24 vs. 34 batteries. The only real difference between these two particular batteries is that the 24 is slightly taller than the 34.
This means that the Group 34 battery will fit easily into the battery box already in your car.
#2 Difference: Terminal Positions
When it comes to the position of the terminals, you will find that with most Group 24 and Group 34 batteries, the positive terminal is located on the left-hand side.
However, be aware that if you purchase either a Group 24F or a Group 34R battery, the positive terminal is located on the right-hand side.

#3 Difference: CCA Rating
If you consider replacing your Group 24 battery with a Group 34 one or vice versa, this is an important feature to consider. You will find that the CCA rating for each of these types of batteries does vary, although not by a great deal.
But it would help if you chose a battery that comes with the same CCA rating as the current battery in your car. It is best to choose a battery with the same or a higher CCA rating for replacing your car’s old one.
If you choose one with a lower rating, it could lead to performance problems in the future. Plus, you may find starting your car a problem.
#4 Difference: RC Rating
Again you’ll find that the RC rating on either of these batteries is very much the same. However, when you look closely at Group 24 vs. 34 battery RC rating, sometimes the 24 comes with a better one than the 34.
It is important that you look closely at any battery’s RC rating. This indicates just how long the battery can power a vehicle should its charging system fail. So the longer it runs for means, the more chance you get your vehicle where it can be repaired.
Which Group Size Battery Is Better: 24 or 34?
Whether you are considering replacing an old Group 24 battery with another one, or a 34, you are probably wondering which would be better?
Well, as already mentioned, you’ll find that these two Group batteries don’t differ very much. So being able to replace a 24 with a 34 is acceptable, and the same goes for replacing a 34 with a 24.
However, when deciding which one is better, it depends on making sure that it meets your vehicle’s requirements, and keep the following in mind:
- Choose the battery that fits easily into the battery box already in your car first.
- When you need a battery to only run the radio/AC and other electrical components when the engine isn’t running, get a deep cycle battery. These batteries come with a higher RC/Ah rating and yet cost less than a conventional battery.
- If you live where it is cold most of the time, go for a battery with a high CCA rating.
- Need a battery to both start and power other electrical equipment in your car, go for a dual-purpose battery.

Yet, it still only measures 10.85 x 6.99 x 7.82 inches and weighs in at just 51.5 lbs. But unlike some other Group 34 batteries, this one only has a CCA rating of 850 and an RC rating of 135 minutes.
What Is The Best Group 24 Battery?
Again, when deciding which Group 24 battery to buy, you have many options to choose from. But here are 3 we think are worth considering investing in.
Best Battery For Deep Cycling
This is a great battery and will provide your vehicle with power for much longer periods. As well as being suitable for use in cars, also ideal for use in smaller vehicles such as mobility wheelchairs, solar systems and even trolling motors.
This sealed lead acid battery measures 10.02 x 6.65 x 8.94 inches and weighs in at just 46 lbs.

Another great battery that can provide power to your car for much longer periods. This is a very versatile general-purpose Group 24 battery that you can mount in any position. It is also able to tolerate a wide range of temperatures. It can also be used for both cycle and float applications.
