H5 Vs H6 Battery. Which is Better?

I have seen people get confused by the different sizes of batteries when talking to others. There are around 7 different sizes of batteries in the majority of cars.

There is not much to choose from when it comes to the size of the battery.

The batteries have different names and cause confusion between the customers. The H series battery is the most used in modern European and American cars.

They are available in a variety of sizes. The H configuration battery sizes have the same height and width. The main difference is the length. 

The BCI Group Sizes are the batteries that are used. There are two different names for the same battery.

Group 47 is also known as Group 48, H6 is also known as Group 48, H7 is also known as 94R, and H8 is also known as 49.

Among the different sizes of batteries, H5 and H6 are the most commonly used. In this article, we will help you understand the differences between the two batteries.

H5 vs H6

The weight of h5 and h6 batteries is the biggest difference between them. H5 batteries are light, but h6 batteries are heavier.

Racing and performance-based use are what h5 batteries are mainly used for.

If you are driving in cold areas, H6 batteries are better because they are heavier and give you more capacity.

It is better to go for the h6 batteries if you own a car that has more than one accessory.

H5 Battery Overview

Medium-size batteries are H5 batteries or group 47 batteries. They are used in light industrial applications like cranking or automotive.

When the primary engine is turned off, these are used in gas engines, mid-range diesel engines, and for power to various electronic and electrical devices.

Many of the h5 batteries are spill-proof and maintenance-free. The dimensions of the group 47 batteries are similar to those of the L2 battery and the EN 55L2 battery.

The battery’s positive terminal is located on the right side of the screen. There are automotive terminals for these batteries. Some of them have nut and bolts terminals as well.

The h5 battery has an average MCA value of 700-750 Amperes, 20-hour capacity in 50-60 Amperes hours, RC or Reserve Capacity of around 115 to 115 minutes, and it weighs around 17 to 19 kilograms.

It can be difficult to distinguish between dual-purpose and starting batteries.

There is no exception for the h5 batteries. Some of these batteries are called starting. These are used in the start & go application.

The batteries allow medium to deep discharges and have a charge well. The dual-purpose batteries can crank internal firing engines and can tolerate cycle application.

When the primary engine is off, you’ll often find these batteries in single battery systems that need the battery to power different systems.

H6 Battery Overview

The H6 batteries and the group 48 batteries are mid-range. They are used as starting batteries as well as dual-purpose batteries.

When the main power is not present, these batteries are often used to power electronic and electric devices. Most of the batteries have spill-proof designs and are maintenance-free.

They come with increased resistance to mechanical shocks. The features of the standard h6 batteries are the same as those of the standard H6 batteries.

The L3 or h6 and EN standards are considered to be group 48 batteries due to their similarity in size.

The positive terminal of the h6 batteries is placed in front of the user.

H6 batteries have an average MCA rating of 800 to 930 Amperes, a nominal capacity of 60 to 72 Ampere hours, an RC or Reserve Capacity value of 120 to 140 minutes and a weight of around 20 to 24 lbs.

The dual-purpose h6 batteries are very versatile and high-end. They have the strength to resist deep discharge applications and provide a large starting current.

The h6 dual-purpose batteries can be used for a variety of applications, including cranking or starting use for security and medical systems, as well as several off-grid implementations, and many more.

Conclusion

Both h5 and h6 batteries are popular in American vehicles. Both have advantages and disadvantages and are used in different ways.

Before buying an h5 battery, make sure to check the base hold-down type, CCA/Ah rating, terminal type, and orientation.

Before buying an h6 battery make sure to check the nominal capacity of the battery, the battery’s RC ratings, the base-hold down type, terminal types as well as orientation, etc.
