H6 and H7 batteries are two battery types that are specially designed for the automotive applications.
They are packed with numerous features that make them suitable for this application area.
While both are lead-acid batteries, they tend to differ in many different ways. Anyone who is keen on the battery characteristics should be able to tell the differences.
And it is those differences that will influence your purchasing decision.
In this guide, we are going to discuss the differences between H6 and H7 battery.
From this detailed guide, you will know which one is perfect for you.
We will end the guide by advising you on where to buy the best H6 and H7 batteries in China.
H6 Battery Overview
Also known as the Group 48 batteries, these batteries are quite common in small vehicles.
H6 is a lead-acid battery whose chemical composition is made of lead and sulfuric acid. Lead and acid combine to produce the electrical energy that is needed for starting up a vehicle.
Other than the engine-startup, the battery can also run a couple of the vehicle electronics and accessories such as the headlights and audio system.
You can also find the in light industry applications.
They are called H6 because they comprise of six cells which are H-shaped.
These six cells are arranged in two parallel rows, each row containing three cells.
The H6 batteries are rectangular-shape and the top terminals are kind of recessed.
In terms of the physical dimensions, H6 measure 278mm×175mm ×190mm (length, width, height)
The weight of these battery ranges between 45lbs and 54 lbs.
Just from the physical dimensions, you can predict the battery performance.
Well, H6 are quite performers, boasting of the nominal capacity ranging between 60 to 72Ah. Their reserve capacity is approximately two hours.
These batteries are capable of hitting up to 800 amps. This is adequate to provide the starting power of a vehicle. In fact, It is more than enough for most SUVs.
Since it is used in automotive, it can be easily charged by the vehicle’s charging system.
H7 battery overview
These are sometimes referred to as the Group94R batteries. They are also lead-acid batteries that are commonly used in the automotive applications. They are considered to be an upgrade from the H6 batteries hence ideal for the high-performance automotive applications.
You are likely to find the H7 batteries in SUVs and luxury vehicles that are equipped with high-end electronic features and accessories.
Just like the H6, H7 batteries are rectangular-shaped and the positive terminals are positioned on the right side of the battery.
In terms of the dimensions, the battery measures 315mm×175mm ×190mm (length, width, height)
The weight of the battery varies between 51 to 57 lbs.
H7 also has a significantly long reserve capacity of between 140 to 160 minutes. Similarly, its nominal capacity is between 76 to 80Ah while it has a cold cranking current of up to 850 amps. This allows it to start vehicles with bigger engine capacities.
H6 vs H7 battery: What’s The Difference?
At this point, we can do a full comparison of the two batteries based on their features and specifications.
From there, you will know which is the right battery for you.
We have discussed the physical dimensions of the two lead-acid batteries. They have the same width and even height. However, there is a difference in their length with the H7 being slightly longer than the H6 battery. The previous measures 315mm while H6 measures 278mm.
Does this difference matter when it comes to the interchangeability of the battery? Not really.
Position of the terminals
This is another way in which we can distinguish the H6 vs H7 batteries. There is a difference in terms of their terminal positions.
Both have their positive terminals positioned in the same way. The main difference comes in terms of how these terminals have been designed and configured.
The terminals on the H7 batteries are slightly wider than those on the H6 terminals.
While this does not have an impact on the functioning nor performance, it will help you to identify the battery easily.
Well, this is vital when it comes to comparing batteries. From the specs, H7 is heavier than the H6.
H6 weighs 45-54 Ibs while H7 weighs between 51 to 57.
If you are keen on the automobiles, you must know that the weight matters, especially for competitive vehicles.
The weight of the battery may directly affect its performance. If all factors are constant, a lighter vehicle will have an extra edge over a heavier one.
However, having a heavy H7 battery may come with its set of benefits. For example, it has higher capacity and delivers better electrical performance than the H6 battery.
Cold cranking amps
Cold cranking amps refers to the amount of current required to start the engine at cold temperatures. H7 battery has a higher cold cranking amps than the H6 battery. I
The amps for the H7 ranges between 800 to 850 while the cranking amps for the H6 range between 720 to 800.
Th H7 has an advantage such that you will still start the engine during cold days. In other words, it is more suitable for the cold temperatures than the H6.
However, cold cranking amps should not be a major driving force that motivates you to buy a particular battery type.
The nominal capacity of a battery refers to the current discharge by a fully charged battery under normal conditions.
H7 have higher nominal capacities (76-80Ah) which is higher than H6 which is 60-72Ah.
Application in automobiles
When it comes to the application, it is all about preference. H6 is mostly used in most European and American cars. The same applies to the H7 batteries.
This means that there is no specific battery that is exclusive for a particular type of car.
So, what is the difference between H6 and H7 batteries? We have outlined all the key pointers and you should be able to distinguish them.
And when it comes to purchasing these two batteries ensure that you get from the right suppliers.
