A car battery is an essential part of a car that impacts outstanding performance and safety. Identifying how much does a car battery weigh is a real concern when you intend to replace your old models. But how can you do that? In this article, we will demonstrate a range of useful details to help you.

Ways to identify how much a car battery weighs

One of the most popular ways a driver can know how much a normal car battery weighs or capacity is to check out the label. Normally, the manufacturers will inscribe detailed information, including their battery weights on the packaging label. Hence, that is an effective way to get a definite answer without any time-consuming process.

Unfortunately, that is not the case for some batteries. So, if you are also in this situation, it is about time you should carry out some research so that you can select high-quality batteries that meet your demand.

How much a typical car battery weighs depends on numerous factors such as its standard size and constituents. The average battery weights range from about 30 to 50 pounds, which is approximately 13.6 to 22.67 kg.

Types of battery weights

There are three basic kinds of battery weights, which are: lightweight batteries, standard batteries, and empty batteries.

Light Weight Battery

These battery weights range from 10 to 20 pounds and are wise choices for powering small car designs. Lightweight batteries are not only energy-saving but also extremely efficient. However, Lightweight batteries can only work for a period of time and are not feasible for either long-term use or daily reliability.

Standard battery

Have you ever wondered ‘How much does a standard car battery weigh?’. The standard car batteries’ weights range from 40 to 60 pounds, much heavier than lightweight batteries. The factors that define the standard battery size are the passenger vehicles you are driving and the amount of charge you need as well.

Empty battery

As you can guess from these batteries’ names, they have nothing in them, neither lead-acid nor lithium-ion. For a standard and heavy battery, it usually weighs about 15 pounds, while for a lightweight design, the weight is around 7 pounds.

Types of batteries

In this article, we will list the 5 most popular types of batteries: SLI batteries, Deep cycle batteries, Lithium Ion batteries, Lead Acid batteries, and Wet Cell batteries. The biggest difference between them depends on technology.

SLI battery

SLI battery stands for Starting, Lighting, and Ignition battery. Many brands use this type of battery for most electric cars on the roads. It can deliver a powerful start of the car in a short burst of time and then maintain a stable power capacity when driving.

Deep cycle

It is able to offer long-lasting power. Not only used in cars, but it is also used for other transportation such as marine vehicles, and so much more that need stable power over a long time.

Lithium Ion battery

A Lithium Ion battery is also known as a Li-on battery, which is the most compatible type of battery on the market nowadays. It is getting more and more popular these days since it can store more charges.

Another plus point is that compared to other conventional batteries with similar power, it weighs less. Its life span is also pretty long, about 3 to 4 years.

Valve-Regulated, Lead-Acid battery

This VRLA battery has the lowest maintenance among the types of batteries we mentioned above. When this battery starts to degrade, the only thing you can do is replace it with another new one.

There are two typical kinds of Lead Acid batteries: gel cell and absorption glass mat (also called AGM). The former is better when it comes to cycle life, whereas the latter can make powerful short bursts.

So how much does a lead acid car battery weigh? Most of the Battery Acid is quite heavy, and on average, it weighs about 39 pounds (17 kg)

Wet Cell battery

In terms of price, this model is much more affordable. Nevertheless, it requires meticulous care and maintenance on the regular basis. This battery needs water to create electrolytes as a power source. Hence, it is vital you remember to add water regularly to this battery.


Battery sizes

It goes without saying that standard size plays an essential role in affecting how much a battery weighs. The smaller it is, the fewer components it contains. That is the reason why a smaller battery weighs less compared to a bigger model.

If your car is big and its engine requires a powerful battery to operate, we suggest you should go for a large-size battery, which may weigh as much as 50 pounds. In other cases, a lighter battery can do its amazing performance and guarantee your safety.

Why does knowing the battery weight matter?

The weight of a battery is an important matter to consider because that will determine if a driver can carry it with ease or not. Another reason is that quality battery weight can directly affect the efficiency of your quality car performance.

Therefore, if you have the intention of purchasing a new battery, we recommend you select a model that has the same weight as your old option. A similar weight means it is more likely to be as powerful as the previous battery model.

Either too light or too heavy a battery for your engine will impact the terrible performance of your safety and cause damage to your vehicles. And we believe that no one wants that to happen.
