Sizing Facts for Modern Cars
There are only about 7 sizes of batteries used in 90% of cars today. Most cars built in the last 15 years use one of these sizes.
You might be surprised to know that there are often two names for one battery size. For example, the "Group 48" size used in the USA is also called the "H6" size by European manufacturers.
If you have a European car, your choices will be fairly easy. Most European cars use one of four battery sizes: H5, H6, H7, or H8. These sizes are used in about 95% of all European cars.

A key factor in the ease of battery replacement in European cars is the standardized battery mounts. These mounts are designed to fit the width of the batteries, which is the same for all four sizes. This means you can use any of these sizes in your European car, as long as it fits the width.
The physical dimensions of BCI Group 48 batteries are 278 mm (11 in) in length, 175 mm (6 7/8 in) in width, and 190 mm (7 1/2 in) in height. This size corresponds closely with DIN H6, L3, and EN 66L3 battery standards, allowing for interchangeable use across these formats.
Here are the physical dimensions of Group 48 batteries in both inches and millimeters:
The H6 battery is a popular size used in many mid-size vehicles, including the Volkswagen Jetta, Passat, and Golf, as well as the Audi A3, A4, and Q3. If you're unsure whether your vehicle requires an H6 battery, be sure to check your owner's manual or consult with a professional.
Alternative Sizes
If you're having trouble finding the right battery size for your car, don't worry, there are some alternatives to consider.
Most European cars use one of four battery sizes: H5, H6, H7, or H8, which cover about 95% of all European cars.
If you can't find an H6 battery, you might consider an alternative size, but always confirm dimensions, terminal orientation, and battery tray compatibility before choosing.
Group H5 (47) is a slightly smaller battery, suitable for vehicles with lighter electrical loads, measuring 9.56" x 6.94" x 7.5".
Group H7 (94R) is a larger capacity battery, slightly longer than H6, requiring sufficient tray length, measuring 12.4" x 6.9" x 7.5".
Group 96R is a slightly shorter height battery, comparable in footprint to H6, measuring 9.6" x 6.9" x 6.9".
These alternative sizes can be used if the H6 size is not available, but it's essential to double-check the compatibility of the battery with your vehicle.

Battery Codes and Standards
Battery codes are used to identify specific battery types, and understanding them can be helpful when shopping for replacements.
The code H6 is actually an SAE code, which is one of the standards used to classify batteries.
The H6 code refers to batteries with a specific physical size and terminal placement, making them compatible with BCI Group 48 batteries.
Other codes like L3 and 66L3 are also used to classify batteries, with L3 being the DIN code and 66L3 being the European EN standard.
These codes are essentially alternate designations, but they all refer to batteries with similar characteristics, making them interchangeable in many applications.

L3 and 66L3 Battery Codes for BCI 48
The L3 and 66L3 codes refer to DIN and European EN standards, respectively.
These codes correspond to batteries with similar physical sizes and terminal placements, making them equivalent in size and compatible for the same applications as BCI Group 48 batteries.
The physical dimensions of BCI Group 48 batteries, which are around 11 inches in length, 6 7/8 inches in width, and 7 1/2 inches in height, are closely matched by the L3 and 66L3 codes.
This uniformity in size facilitates replacement compatibility in many cars, trucks, and equipment.
Here's a quick reference to the physical dimensions of BCI Group 48 batteries:
These codes, H6, L3, and 66L3, are alternate designations from different standards, but they all refer to batteries with the same physical sizes and terminal placements, making them interchangeable for BCI Group 48 applications.
T5 T6
T5 and T6 batteries have the exact same footprint as H sizes, but they are about 3/4-inch lower in height.
This means that if you're looking for a replacement battery, you can easily find one that fits the same space, just check the height to ensure it's the correct type.
The difference in height is about 17mm, which is a relatively small change but can make a big difference in the overall size of the battery.
Battery Comparison
Group 47/H5 and group 48/H6 batteries have the same width and height, but differ in length by 36 mm (~1.42 inches).
The main difference in dimensions between these two battery groups is in their length, with group 48/H6 batteries being 1.42 inches longer than group 47/H5 batteries.
Here's a comparison of their dimensions:
- Group 47/H5: 9 9/16 x 6 15/16 x 7 1/2 inches (242 x 175 x 190 mm),
- Group 48/H6: 11 x 6 15/16 x 7 1/2 inches (278 x 175 x 190 mm).
H5 vs Dimensions
The H5 and H6 batteries have some notable differences when it comes to their dimensions. Specifically, the length of the H6 battery is 11 inches, which is 36 mm (or about 1.42 inches) longer than the H5 battery.
Let's take a look at the exact dimensions of each battery:
- Group 47/H5 Battery Size: 9 9/16 x 6 15/16 x 7 1/2 inches (9.5625 x 6.9375 x 7.5 inches, 242 x 175 x 190 mm)
- Group 48/H6 Battery Size: 11 x 6 15/16 x 7 1/2 inches (11 x 6.9375 x 7.5 inches, 278 x 175 x 190 mm)
As you can see, the H5 and H6 batteries have the same width and height, but the H6 battery is noticeably longer. This difference in size affects the internal volume and capacity of the batteries, with the H6 battery having a larger internal volume and thus larger capacity.
H5 vs. Charts
If you're trying to decide between an H5 and an H6 battery, there are some key differences to consider. The H5 vs. H6 Battery Comparison Charts can help you make an informed decision.
One of the main differences between H5 and H6 batteries is their size. H6 batteries tend to be larger than H5 batteries.
When comparing the two, it's essential to look at their specifications. The H5 vs. H6 Battery Comparison Charts list some of the most popular batteries with their most important features and specifications.
The charts show that H5 batteries typically have a higher capacity than H6 batteries. This means they can hold more energy.
Some H5 batteries have a higher voltage than H6 batteries, which can be beneficial in certain situations.
H5 vs. H5 CCA, RC, Weight
