Difference between H7 and 94R Batteries

(Last Updated On: November 7, 2021)

Making a choice between an H7 or 94R battery for your vehicle is non-negotiable. Either of both options for a wrong car would leave you with regrets.

Understanding how each battery group works, their differences, peculiarities, and the best batteries in their group would help you make a more cost-effective purchase decision.

In this article, I will discuss extensively all you need to know about H7 and 94R batteries. I would also include recommendations to guide your purchase decisions.

Are there any differences between H7 and 94R batteries?

H7 and 94R batteries are essentially the same. They are also known as L4 and LN4 batteries on the market.

Over time manufacturers use H7 batteries for private automobiles more than commercial vehicles. You’d usually find them in cars like Volkswagen, BMW, Ford, Mercedes-Benz, and Audi. On the other hand, 94R batteries are used for long vehicles, automobiles, and private vehicles. This battery is remarkably versatile and finds compatibility for a wide range of cars.

Since both batteries are the same, they are interchangeable. Nevertheless, it would be best if you did this with the following considerations in mind.

Size

The size of the battery you buy is an important consideration you must make before purchase. A bigger or smaller battery (physical dimension) is not perfect for your car. You need a battery that fits best for your vehicle.

Before making a purchase, you should make appropriate measurements or use your old battery as a reference. H7 and 94R batteries have the exact physical dimensions (7.5 × 12.5 × 7inches). It’s smart always to double-check and examine battery size when you want to make a purchase decision.

Cold Cranking Amps

Cold-cranking amps are an essential rating for batteries’ optimum performance during cold weather. A battery with a low CCA would fail to kick start your car in cold weather.

While CCA is important, you should consider your previous battery’s CCA and how cold your environment is when you make a purchase decision.
Either an H7 or a 94R battery supplies a CCA current between 620-920 amps. Depending on your car’s minimum demand for CCA and the weather in the surrounding environment, you can choose a battery that works efficiently for your car.

Reserve Capacity

The reserve capacity measures how long a battery can supply 25 amps of current without a voltage drop below 10.5 volts. This quantity measure determines the battery’s charge capacity and indicates how well a battery stores power.

A battery with a higher capacity usually has more reserve capacity. Even better, a significant reserve capacity means your battery can accommodate more workload. HR and 94R batteries have a reserve capacity of 135 minutes.

This means either battery rarely has a better battery than the other. Nevertheless, other considerations can help you pick what battery works better for your car.

Maintenance

The maintenance of a battery is another crucial consideration to make before purchase. Although H7 and 94R batteries are the same, they have slight differences in their maintenance needs.

It would be best if you chose batteries that are spill-proof and easily maintained. Even better, the sturdier the battery, the more it’s durable.

It would come in handy to also consider the weight of the battery. A lightweight battery that fits other key specifications that your car needs is a big win.

Lightweight batteries improve the mileage and overall load of your cars.

H7 batteries are usually lighter than 94R batteries. Nevertheless, the rule is to consider all we discuss and choose what fits your needs. Your decision shouldn’t be based on only the weight of your battery. CCA, reserve capacity, and maintenance are more important considerations.
