The majority of UTVs will require a 12-volt battery and hence belong to Group 26 of Battery Group Size.
The size of the battery you need will depend upon the specific make and model of your UTV. The general physical dimensions of a UTV Battery are 8.1 X 6.80 X 7.75 (Inches).
However, the dimensions and voltage should always be checked by referring to the user manual as there are variations across different models.
What are Battery Group Sizes?
In general, the exact physical dimensions of a battery are provided by group sizes, which have been established by the Batteries Council International (BCI).
For the length, width, and height, measurements are given in both inches and millimetres.
An industry standard known as the battery group size describes the actual physical dimensions of a car battery (height x width x length), as well as its polarity (where the positive and negative battery posts are located on the battery).
This makes it easier for car, truck, and SUV manufacturers to consider battery size when designing a vehicle.
Battery group sizes offer a streamlined, industry standard for automotive batteries, assisting both the battery and vehicle makers in lowering costs.
It’s simple to replace your battery at your neighbourhood Auto Care since they have standard battery group sizes, and technicians and automotive advisers can make sure your battery is fitted correctly.
After all, it’s unlikely that you are working with your grandfather’s property yacht, which had enough space inside for sleep.
Getting the wrong size battery and installation will feel like putting a square block in a round hole. Newer automobiles pack more equipment into a smaller area.
How Do I Read BCI Group Numbers?
94R is an illustration of a BCI group number. The size of this battery set is 12.4 x 6.9 x 7.5 inches. Its posts are at the top, and the positive terminal is on the right post. One more illustration is a 4D group.
The size of this battery is 20.75 x 8.75 x 9.8 inches, and it is designed for commercial vehicles.
The positive post is on the right of the posts, which are positioned at the top.
The left post is the positive terminal of A Group 100 and 101 automobile batteries, which have their posts on the side.
When hunting for your new battery, this should help you understand what the various BCI group numbers signify.
Additional examples are Group GC8 (marked for golf carts) and Group U1, which are meant for utility vehicles.
It covers a wide range of battery groups with varied sizes and forms that are intended for usage in cars and light trucks.
I never realized how important the dimensions of a UTV battery are until I learned about battery group sizes.
I’ve been down that road before, and believe me, it’s not worth the risk. If I had this How Long Does A UTV Battery Last? back then, I could have avoided a lot of stress. Don’t make the same mistake.
How to Select the Right Battery for Your UTV?
Knowing what size and capacity battery you need is not enough when replacing the battery; there are several other factors you need to consider. Here is the complete list.
Physical Dimensions
The dimensions of a battery include its length, width, and height, excluding the battery connections, to determine its physical size.
UTV batteries are available in a variety of sizes that are tailored for different uses and engine sizes.
Vehicles with power-hungry equipment require a battery with enough capacity to avoid running out of power too quickly.
Larger engines normally require a battery with higher starting power.
Capacity: Amp Hours(Ah)
The amount of electric charge a battery can give at its specified voltage is known as its capacity, and it is commonly measured in amp hours (Ah). Consider it the battery’s capacity for sustained use.
The amount of current the battery can supply continuously for a given amount of time (often 20 hours) is multiplied by that amount of time to determine the battery’s Ah rating.
Since Ah is temperature-dependent, the test is conducted at 68 °F (20 °C) for results that are comparable.
The reliability of my UTV skyrocketed after I upgraded to a battery with the perfect group size.
Cold Cranking Amps (CCA)
The Cold Cranking Amps (CCA) rating describes a battery’s capacity to produce a surge of power over a brief period of time, whereas the Ah-rating indicates how much current the battery can give over a lengthy period of time (usually 30 seconds).
The majority of the UTV’s power comes from the vehicle’s charging system when the engine is running.
Yet, the battery provides all the power needed to operate the UTV’s electric starter when you turn the key. As a result, the CCA rating is equally as significant as the Ah rating, if not more.
When it comes to powering my UTV, I rely on the optimal battery group size for maximum performance.
Battery Type
Battery types and chemistries can be separated. Lead-acid batteries, which make up the majority of UTV batteries, are available in three basic types: flooded cell (conventional), AGM, and GEL cell.
Choose a lithium-based battery if you wish to upgrade to a battery with a bigger capacity and reduced weight.
Other factors like Nominal Voltage, Polarity should also be known but these are the most required to be known.

With the right battery group size, I can confidently tackle any adventure in my trusty UTV.
Kinds of Batteries for UTV’s
FLOODED
In terms of the multitude of applications and industry demands, such batteries have lead plates in construction with Sulfuric Acid electrolytes.
However, available with separate plate separators, yet the question stops at that moment.
In general, this battery is not available in the sealed form, and it is not compatible to transfer gasses to liquids.
As an alternative, its gasses may be executed externally. Internal gasses generated are capable of extracting into the environment directly unless there is an advanced system.
As well as by the path, gasses, acid form and condensation, and steam can be released at ease.
Leading to maintenance, regular replenishing may cause bad electrolytes through the vent.
Lead plates start breaking down easily when it comes to environmental touch, as a result, easy corrosion and failure of batteries can happen.
However, as per the price, quality is very good in terms of containing good electrolytes as well as charge in itself to perform longer and smooth.
● The most cost-effective choice
● The battery with the shortest lifespan is not as durable as an AGM or lithium battery.
● Plates must be frequently topped up with distilled water as part of the needed maintenance.
Exploring different UTV battery group sizes opened my eyes to the intricacies of vehicle maintenance.
AGM
Absorbed Glass Matte, in short, AGM which is the greatest form of lead-acid batteries. The construction separated 2 cells as if the plate and wrapper were with rigid fibreglass.
It ensures the holding capacity and electrolyte presence with capillary action in its place.
Along with 3 parts, for instance, lead plates, electrolytes, and Fiberglass separators create a single physical rigid bond by means of standing for capillary action.
Similar to the hot water absorption ratio by a towel in the bathtub, capillary action holds the electrolyte and in the confined space which is called Glass Matting makes the battery spill-proof.
If the packaging is right, it not only boasts the internal part’s resistance but also makes the border sturdy, in fact, the lower the internal resistance, the higher the output generates.
In contrast, it loses empowerment to boast the entire system and decreases charging time.
● While more expensive than a flooded battery, you will often save money during the battery’s lifespan.
● Greater longevity: lasts 2-3 times longer than flooded batteries
● Completely sealed, maintenance-free, and spill-proof
● More energy is available than with flooded batteries at higher voltage output, making vehicle starting more dependable.
● faster than flooded batteries at charging
● Low self-discharging rates; maintains charge longer when stored
● more resilient to harsh weather and vibrations
My UTV journeys became more enjoyable once I upgraded to the perfect battery group size.
LITHIUM
● The highest initial cost is expected to result in long-term financial savings because lithium has a longer lifetime.
● improved cycle life—lasts for more than 2,000 cycles
● Completely sealed, maintenance-free, and spill-proof
● Most energy-dense output compared to flooded or AGM batteries
● 2X quicker than lead acid batteries at recharging batteries
● Lowest self-discharge rate and superior ability to maintain charge over flooded and AGM batteries make it ideal for seasonal applications.
● About two times as light as identical lead acid batteries
I never thought I’d be so invested in understanding the dimensions of a UTV battery until I started exploring battery group sizes.
