The most common battery group sizes are 24, 24F, 25, 34, 35, 51, 51R, 52, 58, 58R, 59, and 65. Manufacturers tend to favor a particular battery group size. Many General Motors vehicles in the US have side-post batteries. These do not have battery posts at the top, instead there are cable ends that screw into the side.

How do you read a battery size?
Understanding the specifications1st digit – Voltage. 1-2 = 6 Volt Battery. 5-7 = 12 Volt Battery.2nd & 3rd digits – Nominal capacity. 560 = 60Ah @ 20 hour rate. 660 = 160Ah @ 20 hour rate.4th & 5th digits – The unique code number referencing battery performance and features.
What are the battery group sizes?
In general, these more-common battery group sizes are 24, 24F, 25, 34, 35, 51, 51R, 52, 58, 58R, 59, and 65. Helpful Hint: Some vehicles can handle a larger battery than was originally installed. A physically larger battery usually has more power and reserve time than a smaller battery.
How do I know what size battery my car needs?
Your car's battery group size can be found in the battery section of the owner's manual. If you no longer have access to your original owner's manual, you may also consult the reference guides provided by battery retailers to determine the appropriate battery group size for your car.
How do I know battery group size?
If the battery that originally came with your car is still in it, look for the group size on a label on the battery. The label may be on the top or on the side of the case. Group sizes are typically a two-digit number and may be followed with a letter.
What is the difference between a Group 24 and Group 35 battery?
The difference between the two batteries lies in their ability to store energy. The Group 24F battery stores more energy because of its high-capacity rating. On the other hand, the Group 35 battery stores less energy because it is rated at a lower capacity.
What is the difference between a group 24 and a group 27 battery?
If you compare a group 24 battery and group 27 deep cycle battery together, you'll notice that the mp hours are slightly higher on the group-27 product. This specification difference is made on purpose by the manufacturers. In general, a group size with a higher number has more amp hours than lower values.
Is a higher CCA battery better?
In general, for both CCA and RC, the higher the number the better. However, if you live in a cold climate, the CCA rating should be an important consideration in choosing a battery.
What happens if you put the wrong size battery in your car?
Battery specifications If you use the wrong size battery, this could cause changes in the flow of electrical currents, resulting in power surges that can damage the onboard computers or other components.
How many CCA do I need?
The standard recommendation is a battery with at least one Cold Cranking Amp (CCA) for every cubic inch of engine displacement (two for diesels). CCA rating is an indication of a battery's ability to deliver a sustained amp output at a specified temperature.
What do battery group numbers mean?
This refers to the battery size that will best fit the physical dimensions, terminal locations and type required for your vehicle. The Battery Council International (BCI) assigns numbers and letters for each battery group size. Group size is typically based on your vehicle's make, model and engine type.
What is the difference between a Group 31 and Group 34 battery?
Their group 31 is a 96 AH battery and the group 34 is a 62 AH battery. I might eventually add a solar panel to supplement this setup and provide additional power for other accessories/gadgets when camped for longer periods of time.
What do battery numbers mean?
The standard rating is a based on how many amps you can pull out of the battery over a 20-hour period. For a 100 AH rated battery this means you can draw from the battery for 20 hours, and it will provide a total of 100-amp hours. That translates to about 5 amps an hour (5 x 20 = 100).
What type of car battery is right for your vehicle?
There are two basic battery types below, wet cell and VRLA batteries. A technician at your preferred garage will evaluate your vehicle’s battery and electrical system and help you select the proper car battery group size to power your ride.
WET CELL BATTERIES
Wet cell batteries (flooded batteries) are lead-acid batteries that are specifically designed for automotive use. It is the original rechargeable battery and contains a liquid electrolyte.
VRLA BATTERIES
A VRLA battery, or valve-regulated lead-acid battery, is a sealed battery with no venting of gases. These batteries are ideal for use in small spaces with no ventilation and since they’re sealed, they can be easily stored. VRLA batteries don’t leak or release hydrogen gas and are considered the safest wet cell lead-acid battery.
What is the best source of information to find the recommended battery group size and specifications?
The best source of information to find the recommended battery group size and specifications is your Owner’s Manual.
What is universal battery number?
A universal battery number is simply another battery naming system. They are still in different sizes and shapes. These numbers usually begin with UB followed by a sequence of five numbers and another set of five letters and numbers separated by a hyphen.
What is a BCI 35 battery?
A BCI Group 35 battery is a standard battery size for a wide range of cars and small trucks. It has a top-post design and fits popular models, including Toyota, Nissan, KIA, Ford, and other models. It is the recommended Honda Accord and CR-V battery for many models.
What does BCI stand for in batteries?
These numbers and letters are the BCI group size of the battery. BCI stands for Battery Council International.
What is BCI in car?
The BCI designations include the group definition, dimensions, measurements, types, sizes, and other characteristics. The battery conversions chart can help you to cross-reference battery sizes, but it is also useful to understand the various group sizes that are designated for different types of vehicles.
What happens if you put a bigger battery in your car?
On the other end of the spectrum, if you put a battery that is larger than recommended, it can cause significant damage to your car. The larger battery can cause spikes and power surges that can damage your electronics, including your onboard computer.
How to clean battery terminals?
How do you clean battery terminals and contacts? 1 Remove the battery cables and inspect them. 2 Spray the battery cleaner on the terminals. You can also mix up one tablespoon of baking soda to one cup of water and apply it to the terminals. 3 Scrub the terminals with an old toothbrush or wire brush that is made for this purpose. Scrub until all of the buildup is removed. 4 Rinse off the residue with plain water and allow the terminals to completely dry. 5 Reconnect the battery cables.
What are the different types of car batteries?
5 Different Types Of Car Battery 1 Starting, Lighting And Ignition Batteries: These type of car batteries are found in most automotive around. They work by starting, powering the ignition and even for the car lights. They are discharged at a fast rate and can only produce high power for short periods. 2 Deep Cycle Car Batteries: They have the ability to deliver sustained power for long periods of time. They are common for marine vehicles. 3 Valve Regulated Lead Acid Car Batteries: These type of car batteries does not require a lot of maintenance that most of the others do. 4 Wet Cell Car Batteries: These are referred to as flooded car batteries. They contain an electrolyte that is a solution of an acid in water. They require high maintenance like regular topping using distilled water. 5 Lithium-ion Batteries: They are popular due to their ability to store significant amount of energy. However, they are not that long lasting and need to be replaced often.
