H6 vs H7 battery: What Are Differences?

In the dynamic worlds of electronics and technology, batteries play a big role in providing the power that is needed to run devices and appliances. As long as an application will need power, there is a high chance that a battery may be one of the options that you may be considering to derive your power from. A good battery should be able to provide reliable power that will run the target appliances. When it comes to choosing batteries, you are likely to encounter two options- the H6 and the H7 batteries. What are the differences between the two and which one should I choose for my application? We have the answers to these questions. In this guide, we are going to break down the differences between H6 and H7. At the end of it,  you will be in a perfect position to choose the right battery for your power needs.

Overview of H6 battery

The H6 battery sits at the pinnacle of the modern battery technology. Classified as Group 48 or 66L3, it is considered among the best batteries that one can get in the current market thanks to its efficiency and versatility. It is widely used in applications where power and reliability are of great essence.  Automobile industry is one such application. The battery provides adequate power that is needed to drive vehicles.

Other than in automobiles, the battery is also used in other navigation applications. High impact resistance is among the top reasons why the battery has gained massive fame. Of course, excellent performance is another key reason why the battery is quite popular.

The H6 battery features the premium AGM (absorbed glass mat) technology that enhances the reliability of the battery. It eliminates the need for constant maintenance and also features lea-proof characteristics. The technology makes it possible to use the battery in any environment without worrying about performance or risk of damage. In short, the H6 is more than just your ordinary battery.

Overview of H7 battery and its specifications

The most outstanding feature of the H7 batteries is their versatility. These batteries are suitable for different application areas. Let's take the example of the automobile industry, H7 batteries are used on different types of vehicles both small saloon cars and heavy trucks.

H7 batteries are classified into two broad categories based on their functionalities. These classes are the starting batteries and the dual-purpose batteries. The core purpose of the starting battery is to crank up a vehicle’s engine. It gives the engine adequate power to run. On the other hand, dual-purpose batteries do more than just crank the engine. They supply power to all other critical components and accessories in a vehicle.

Even though the H7 battery may physically appear to be small, they are quite powerful. They can only be compared to the Group 94R batteries as they are similar in many aspects. This also means that they are interchangeable with batteries in the 94R category.  H7 is a perfect battery for someone looking for a compact, powerful, and versatile battery.

Technical specifications of H7 battery

· BCI Group: 94R

· Battery dimensions; 315x175x190 mm

· Terminal positions: Right positive, Left negative

· Reserve Capacity (RC): 140 to 160 minutes

· Cold-cranking amps  (CCA): 800-850 Amps

· Nominal capacity 76-80 Ah

· Weight: 23-26 kg (51-57 pounds)

H6 vs H7 Differences:

 Let’s look  at some of the  key differences between H6 and H7 batteries

Dimensions

From the dimensions, you can already tell that there are some minor differences between the H6 and H7 batteries. While they have the same width and height, the difference is in their length. H7 measures 315mm while H6 measures 278mm. This dimension is more than just for appearance. It has some impact on the handling of the battery and even the performance. The extra length translates to a larger reserve capacity of the battery. The extra length could mean that the  H7 battery has more energy storage capacity than the H6.

Reserve capacity

There is a major difference between H6 and H7 batteries based on their reserve capacities. The reserve capacity (RC) of a battery is important when you need to power the vehicle for long periods in the absence of other power sources. For example, when an alternator fails, the vehicle will be powered by the reserve capacity.

RC is usually defined in minutes. H7 batteries have longer RC than the H6 batteries. This means that they can run for longer periods autonomously without being connected to an external power source. You may consider switching to an R7 battery in case you want a better RC.

Cranking cold Current (CCA)

 CCA is the measure of a battery’s startup capacity when the environmental temperatures are low. It defines the amount of current that a battery can supply when the engine is cold. High CCA means that the battery is well-placed to start the engine even in freezing conditions. When we compare the two batteries, the H7 battery has a higher CCA than the H7 battery.

Price

With everything that we have discussed, you can easily predict the price difference between the two batteries. Since the H7 battery has more superior features and properties than the H6 battery, you should expect it to be more expensive than the H6. So, if you are keen on the price, you know which battery will be suitable for your budget. However, you should compare the features and the cost of the battery before you make the final decision.

Conclusion: Which battery should I choose?

 From this comprehensive comparison, I hope that you are in a perfect position to decide which battery you should choose between H6 vs H7. Just compare each feature and specification of the batteries and choose one that is suitable for your application. Once you have made up your mind, ensure that you buy from a reputable battery supplier. This is the surest way of ensuring that you get genuine H6 and H7 batteries.
