What is the Difference Between H7 and 94R Battery?

Difference Between H7 and 94R Battery

Choosing a battery may look like an easy thing to do, but you will regret it for a long time if you end up buying the wrong car battery. Having the correct battery for your car will definitely make your life easier.

You will not have to be concerned about the vehicle not starting or other issues. It can also save you from being stuck due to a dead battery. That is why it is essential to choose the right battery for your vehicle.

However, the problem here is that market is flooded with a plethora of options. It makes people confused as all manufacturers claim to provide the best car batteries. In fact, some people buy low-quality automobile batteries due to false claims of the manufacturers.

We understand that it is not easy to wade through all of those batteries’ technical jargon alone. That is why we have come up with this guide, differentiating between the two most popular automobile batteries.

The differences between the h7 and 94r batteries will be discussed in this article. So, let’s take a look below to know everything about these two batteries and more.

What is an h7 Battery?

The h7 battery is mainly a lead-acid battery for automobiles. It comes only in a single form and can be worked with a variety of vehicles, which we will talk about later. Not only that, it can be easily installed and has a replacement warranty. To sum it up, installing this battery in your vehicle will bring peace to your mind.

What is a 94r Battery?

The 94r battery is specially designed for passenger vehicles. Sometimes it can also be used for light to medium commercial vehicles. The manufacturers created this battery to deliver a high performance regularly. Besides that, it can control vehicle functions at higher speeds.

Comparison between h7 Battery and 94r Battery

1 – Cold Cranking Amps

The term “cold-cranking amps” refers to the maximum current these batteries can provide. The h7 battery delivers up to 750 amps, which is why it is ideal for light passenger automobiles.

When it comes to commercial vehicles, it has a low amperage. This is one of the main reasons why this battery cannot be used in commercial automobiles.

Talking about the 94r battery, it offers from 620 to 920 amps. It is ideal for a variety of vehicles due to its higher amperage rating.

The lower amperage batteries are typically used in passenger automobiles, while the higher amperage batteries are suitable for commercial vehicles. This battery’s versatility stems from its higher amperage rating.

The 94r battery has an advantage on this parameter as well.

2 – Compatibility

The h7 battery is widely used by the manufacturers of private automobiles, including Volkswagen, BMW, Ford, Mercedes-Benz, Audi, and more. You’ll rarely see a battery like this in a commercial vehicle.

On the other hand, the 94r battery is a lot more famous than most batteries. This automobile battery can be used for both commercial and passenger vehicles. It is one of the most used batteries due to its versatility.

Automobile manufacturers, including BMW, Porsche, and Volkswagen, are among the many companies that use it. It’s used by small cars and larger SUVs, and commercial vehicles, becoming one of the most common batteries on the market today.

When it comes to compatibility, the 94r has an edge.

3 – Size

H7 Battery Size

A car has limited space for the battery of the car. In the majority of instances, the slot is also not adjustable. Therefore, make sure to check the battery’s size before making a purchase.

When you look at the average size of the H7 battery, you’ll note that it’s about 7.5 inches long “7” x 12.5″ x 7″. It may seem too small of a size.

But, you must remember the 94r battery’s size as well. Looking at both batteries at the same time will help you choose the right battery for your vehicle according to the size’s requirement.

The 94r battery measures 7.5″ x 7″ x 12.5.” All in all, there is no difference when it comes to size.

You can definitely replace one battery with the other only if all the other requirements match perfectly.

4 – Reserve Capacity

The reserve power of a battery refers to the amount of time it can provide 25 A of current at the maximum possible voltage. When the cars start, this usually is necessary.

The battery’s reserve power is greater the higher it is. The reserve capacity of a battery also shows how much additional load it can handle.

The h7 battery has a 125 to 135 minute reserve time. Whereas, the 94r battery has a 135-minute reserve time.

Choosing one of these batteries based on this parameter is difficult. This is because the reserve power of both batteries is almost identical.

Considering that the voltage and the amperage of the 94r battery are higher, you should choose if you can go with any of these.

5 – Weight

Weight Comparison Between H7 and 94R Battery

Your vehicle can comfortably bear the weight of a large battery. However, if the exact requirements are available at a lower battery weight, you can choose that battery over the bulkier ones.

As a result, the load of your vehicle would undoubtedly be reduced. It will save you money in the long run by reducing wear and tear.

Not only that, but it will also boost the mileage of your automobile. Therefore, keep this consideration in mind when choosing the battery. The H7 battery is around 51 pounds, while the 94r battery weighs around 57 LBS.

The h7 battery is on the lighter side in terms of weight. The key thing to remember here is to think about weight in combination with other factors. The amperage should be included in these criteria. Only then, you can have a clearer idea.

The current rating of the 94r battery, on the other hand, usually is on the higher side. This battery’s higher current makes it ideal for frequent and heavy use.

As a result, if you need more fuel, you have no choice but to use the 94r battery.

Factors to Consider to Buy the Right Battery for Your Vehicle

Since we have known the differences between h7 and 94r battery, let’s get to know about the factors to buy the right vehicle battery.

Most automobile batteries come with a lifespan of 3 to 5 years, depending on the climate conditions and nature of the trips. Following are the few factors to consider when buying a battery for your vehicle, so you can choose the best car battery without wasting your time and money.

1 – Position of Terminals

Accumulator Charging Battery Terminals

The polarity of the vehicle is affected by the location of the positive terminal, and there is a chance of shorting if the positive terminal makes contact with the car’s metal shell. Therefore, it is critical to determine if the positive terminal is on the right or left side of the vehicle, depending on the model.

2 – Maintenance

There are two types of maintenance situations here: low maintenance and maintenance-free. The liquid electrolyte in a maintenance-free car battery is typically sealed, and it can operate for the entire battery life without having to be replaced. Low-maintenance batteries have caps that can be unsealed to allow for the addition of distilled water regularly.

3 – Power Requirement

The words Cold Cranking Amps (CCA) and Cranking Amps (CA) are interchangeable (CA). Cranking Amps refers to the amount of energy needed to start a vehicle at 32 degrees Fahrenheit. In comparison, Cold Cranking Amp refers to the battery’s capacity to start a vehicle at 0 degrees Fahrenheit. CCA is essential in cold climates, and higher CCA batteries are recommended.

4 – Warranty

It’s a good idea to think about warranties and choose a battery with a long duration of free replacement. You can determine the warranty period by combining the prorated period and the free replacement period. For a limited time, the prorated duration provides for partial reimbursement of the battery purchase price.

5 – Battery Freshness

A code on the battery that consists of a letter and a number shows the battery’s freshness. The letter denotes the month, while the number denotes the year of manufacture. For example, B/4 denotes February 2014. Never purchase a battery that is more than six months old from the date of manufacture.

The Bottom Line

We hope that you find these differences between h7 and 94r battery useful. The h7 battery and 94r battery can be interchanged in most vehicles. But you must not do so without any knowledge or precautions.

Be sure to first examine the specifications of the battery, so you can make the right decision as per the situation and requirements.

Talking about the comparison, the 94r battery is better than its competitor due to the higher current output. Not only that, but the battery’s reserve time is also higher than the h7 battery.

Hence, if you have to choose between these two batteries, go for the 94r battery.
