Every car needs a battery for it to function appropriately. But, you cannot just pick any battery and expect it to work in your vehicle. There are car battery group sizes that fit into different vehicles. With this in mind, do you understand what the different sizes are and how they work?
By understanding a BCI battery chart, you will understand how to replace the life source in your vehicle. Batteries differ in a few ways like cell type, purpose, and even chemistry, too. But, ultimately, when you understand how the grouping works, then you will be good to go wherever you roam.
How to Find Your Car Battery Group Size
When it comes to getting the right car battery group size, there are different physical dimensions that you should know about. There is an organization that can help with this. The Battery Council International (BCI) determines letters and numbers for the size of the battery group.
Usually, the car battery group size is sized up by the engine, make, and model of your vehicle. In some cases, some cars can use a variety of batteries. Still, know which batteries work or not. This way, you will not have to worry about your car to have some awful problems.
With the help of a replacement guide, you will get the correct battery size with ease. To this point, all you need to know if the battery will fit under your engine’s hood or not. This can all come together with the help of the vehicle’s manufacturer’s designations.
Types of Car Batteries
Knowing what type of battery can be an overwhelming thing. Of course, every brand of battery, from Firestone to Odyssey, has its successes and failures. Today, we will talk through some of the main classifications of batteries. There are dozens of machine-based batteries, but here are the top-7.
Group 8D – This type of battery is very large and used for commercial purposes. A battery like this is used for recreation vehicles (RVs), security systems, and medical applications. One of the most used 8D batteries includes the Gel-Cell Sealed Lead Acid (SLA), which has lithium iron phosphate.
Group 24 – A multipurpose battery, like Group 24, is used for the United Parcel Service (UPS). Additionally, these batteries can be used for wheelchairs and other industrial technologies. As a mid-sized battery, there are a lot of different dimensions. This can cause issues when trying to fit a Group 24 battery in the battery compartment.
Group 27 – A Group 27 battery is also really large, like the 8D version. This battery has an Ah range from 66 to 110. Furthermore, they are extremely heavy. They can range from 54 to 70 pounds. When it comes to Group 27 batteries, there are 3 types: Group 27, 27H, and 27F.
Group 31 – If you own a boat or other marine technology, a Group 31 battery might be right up your alley. Truly, this is a very popular model on the market today. This is a decently large battery, but it varies in design, use, and chemistry.
Group 34 – A group 34 battery is not as large as a Group 31 battery, but it is a solid medium to a large battery. With an Ah range from 50 to 75, you will love the reserve capacity from 100 to 145 minutes. The nice thing about this battery is it is not that heavy, as it ranges from 37 to 51 pounds. This type of battery is perfect as a deep cycle option and it has amazing cranking properties.
Group 35 – If you own a truck, car, and/or RV, there is a good chance that a Group 35 battery could be good for you. As a dual-purpose battery, this option can also be used as a great back-up battery if you ever need an extra one. Some of the best Group 35 batteries are an Absorbent Glass Mat (AGM), as well as the SLA battery.
Group 65 – Another industrial battery is a Group 65. But, automotive and marine options can use this type of battery, too. With a range of 750 to 950 CCA, you will also be impressed by the weight only going from 45 to 55 pounds per battery.
Differentiating Group Battery Sizes
There is not a rule of thumb when it comes to differentiating group battery sizes. In terms of length, a battery can range from 7 inches to over 20 inches. The width has a smaller range around 5 inches up over 7 inches. Lastly, the height battery ranges from around 7 inches up to over 9 inches.
Even with the ranges of batteries, there are specific groups you should get acquainted with. These include the side-post, recessed top post, and the standard top post. Let’s start with the side-post option.
Side-post batteries use Group 70, 74, 75, and 78. These batteries have cable ending with the help of a screw pressed into the battery. With a recessed top post battery, this type of battery is ideal for any manufacturer from Europe. These manufacturers include BMW, Audi, Volkswagen, Ferrari, and much more. This includes group size numbers like 41, 42, and 47-49.
Lastly, the standard top post batteries are for Japanese cars. Imports and American vehicles also fit the bill as well. The range of numbers includes 24, 25, 34, 35, a variety of numbers in the 50s, and 65. These batteries make a connection with the metal hood, which causes a great spark.
Various Batteries Options
When it comes to the purpose of a battery, you can buy one to start a vehicle, as well for dual purpose and deep cycle. Also, there are a ton of cell types reaching from AGM, flooded cell, and gel cell.
A gel cell battery uses a purely liquid electrolyte. These batteries are extremely tough. They will not break down when the temperature gets hot or if any physical shock happens. In specific, a gel battery is dry and sealed when it is ready to be used in a vehicle.
On the other hand, an AGM battery uses a glass mat without flooding any plates at all. With the help of thin fibers, they have meshed together for the most efficiency. There will be no spilled battery acid with this option either. Lastly, chemistry uses lead acid, lithium, NiMH, and NiCd.
Final Verdict
Now that you have come to the end of the article, it is up to you to find the right group size battery. When you have the battery in mind, replace it safely. Then, you get to enjoy the roads wherever you travel to. Have a great year knowing your battery will be ready to roll wherever you decide to travel.
