Besides, your car battery weight is also important as it affects the overall performance of your car. Because power capacity is pretty much related to the battery weight. When your car battery fails to meet the power requirements, your car may end up giving you poor performance.

So, it is highly important to choose a new battery which weight is the same as the factory battery when you need to replace it. Furthermore, knowing the actual battery weight will help you to determine whether you are capable to lift it if needed.

Why are Car Batteries Heavy?

The weight of the battery is mainly depending on the build material. In most cases, car batteries are made of lead-acid. Lead along with a water-based electrolyte solution made the main components of a typical car battery.

Even though this kind of material makes a car battery heavy, it works like a good source of car power. However, there are other types of car batteries available in the market. Another well-known type of battery is the Lithium battery.

If you have an electric car in the garage, this type of battery can be the best fit for you. Although Lithium batteries are comparatively lighter, you’ll get a more efficient user experience from them. However, these kinds of batteries are quite expensive.

How Can You Know the Weight of a Car Battery?

If you need to know the weight of a car battery, you can find it in the following ways.

Checking the Level of Battery:

The easiest way to determine your car battery weight is by checking the packaging. You may also find the weight on the battery level. You may find the battery weight in pounds when you check the level.

Checking The Size of the Battery:

Another way of determining the weight of a car battery is by checking the battery size. No wonder, the size of the battery will give you an idea about the weight. You can check the BCI group of the battery. You can do it by checking its size.

Now, every car battery for a specific BCI group has the same weight in most cases. In a general sense, if your car battery has a large size, the chance is you’ll end up having more weight in it.

Why Battery Size Matters

As I mentioned above, the overall size of the battery is an important factor that determines the weight of the battery. If you have bigger batteries, your battery will end up having more weight. Because, in a large battery, there will be more components which will, in turn, contribute to the overall weight of a car battery. Besides, if you drive a car with a large engine, it is so obvious that it needs more power.

Hence, you’ll need a large battery for it. If I become more specific, I must say, you should find a car battery that weighs at least 50 pounds, in case of a large battery. Similarly, when it comes to a battery that comes in a small size, there will be fewer components. So, the overall weight of the battery will be low as well.

Types of Batteries Weight

There are different types of batteries based on their Weight. Below I will discuss them.

Lightweight Batteries:

If you have small cars, typically they have these types of batteries. They usually save energy so that you’ll get the maximum level of efficiency. So, how much does a battery weigh if it’s lightweight? It can be anything in the range of 10-20 pounds. No doubt, these batteries are pretty much good for small types of cars.

Standard Batteries:

If you talk about standard types of car batteries, their weight lies between 40-60 pounds. The battery size always varies on your car model. However, you should keep in mind that the age of the battery plays also an important role in determining the weight of the battery.

Empty Batteries:

As you can guess from the name, these types of batteries have nothing in them. No components are present in these batteries. Whether you talk about lead-acid or Lithium-ion components, you’ll not find anything in them. Empty batteries often weigh 15 pounds when you talk about standard models. On the other hand, if you talk about lightweight models, empty batteries are 7 pounds.
