4 AGM Car Battery Benefits (Pros & Cons)

In this article, I will be exploring the various benefits of using AGM (Absorbed Glass Mat) car batteries in your vehicle. From their longer lifespan and higher performance to their greater safety and environmental benefits, AGM batteries offer a range of advantages over traditional car batteries.

Whether you are a car enthusiast looking to improve your vehicle’s performance or simply want a reliable and safe power source for your car, AGM batteries are worth considering. In the following sections, we will delve into each of these benefits in more detail.

First, let’s define what AGM batteries are. AGM stands for “Absorbed Glass Mat,” and these batteries are a type of car battery that was developed in the 70s. They are different from traditional car batteries in that they have a sealed design, which means they don’t require any maintenance (like adding water).

AGM batteries also have a higher cranking power and faster recharge time, which makes them a good option for high-performance vehicles or for those that are frequently started and stopped.

Now that you have a basic understanding of AGM batteries, let’s dive into the benefits of using them in your car.

1. Longer Lifespan

One of the key benefits of AGM car batteries is their longer lifespan compared to traditional car batteries.

Below I will go into the various factors that contribute to the extended lifespan of these batteries, including their sealed design, lack of maintenance requirements, slow self-discharge rate, and durability.

Understanding these factors can help you make an informed decision about whether AGM batteries are the right choice for your vehicle.

Sealed design

AGM batteries are sealed, which means that there is no need for maintenance like adding water to the cells. This helps to prevent damage from acid leaks and extends the overall life of the battery.

Lack of maintenance requirements

Because AGM batteries are sealed and do not require maintenance, they are less likely to be damaged by neglect or improper handling. This also means that you won’t have to constantly check the battery’s water levels or add water to the cells, saving you time and effort.

Slow self-discharge rate

AGM batteries have a slow self-discharge rate, which means that they retain their charge for a longer period of time when not in use. This helps to extend the lifespan of the battery and makes it more reliable over time.

Durability

AGM batteries are also more durable and resistant to damage compared to traditional car batteries. They can withstand higher temperatures and are less likely to be damaged by vibration or shock. This makes them ideal for use in high-performance vehicles or for those that are frequently started and stopped.

In summary, the sealed design, lack of maintenance requirements, slow self-discharge rate, durability, and recyclability of AGM batteries all contribute to their longer lifespan compared to traditional car batteries. This makes them a reliable and cost-effective choice for vehicle owners.

2. Higher Performance

One of the key benefits of AGM car batteries is their higher performance compared to traditional car batteries. Here are a few factors that contribute to the improved performance of AGM batteries:

Higher cranking power

AGM batteries have a higher cranking power, which means that they are able to provide a stronger burst of energy to start the vehicle’s engine. This is particularly useful for high-performance vehicles or for those that are frequently started and stopped.

Faster recharge time

AGM batteries also have a faster recharge time compared to traditional car batteries. This means that they are able to hold a charge for a longer period of time and can be recharged more quickly after use. This can be beneficial for those who frequently use their vehicle and need a reliable power source.

Greater capacity

AGM batteries also have a greater capacity compared to traditional car batteries, which means that they are able to store more energy. This can be useful for those who need a power source for extended periods of time, such as when camping or driving long distances.

Improved reliability

The improved cranking power, faster recharge time, and greater capacity of AGM batteries all contribute to their improved reliability. This means that you can rely on AGM batteries to start your vehicle and provide a consistent power source when you need it.

In summary, the higher cranking power, faster recharge time, greater capacity, and improved reliability of AGM batteries all contribute to their improved performance compared to traditional car batteries. These factors make AGM batteries a good choice for high-performance vehicles or for those that are frequently started and stopped.

3. Greater Safety

Another benefit of AGM car batteries is their greater safety compared to traditional car batteries. Here are a few factors that contribute to the enhanced safety of AGM batteries:

Sealed design

As mentioned earlier, AGM batteries have a sealed design, which means that they do not produce gas or acid leaks. This makes them safer to use and reduces the risk of fire or damage to the vehicle.

Non-spillable

AGM batteries are also non-spillable, which means that they do not release any liquid or gas if they are turned over or damaged. This makes them safer to transport and handle, and reduces the risk of accidents or injuries.

Low internal resistance

AGM batteries have a low internal resistance, which means that they are able to discharge and recharge more efficiently. This reduces the risk of overheating and makes them safer to use.

Environmental safety

In addition to the safety benefits for the user, AGM batteries are also safer for the environment. They do not contain harmful lead or acid and can be recycled more easily, which helps to reduce waste and pollution.

In summary, the sealed design, non-spill ability, low internal resistance, and environmental safety of AGM batteries all contribute to their enhanced safety compared to traditional car batteries. These factors make AGM batteries a safe and responsible choice for vehicle owners.

4. Environmental Benefits

In addition to their longer lifespan, higher performance, and greater safety, AGM car batteries also offer a range of environmental benefits. Here are a few ways in which AGM batteries are more environmentally friendly than traditional car batteries:

No harmful lead or acid

AGM batteries do not contain harmful lead or acid, which makes them safer for the environment. Traditional car batteries contain these substances, which can leach into the soil and water supply if not disposed of properly.

Reduced waste

AGM batteries have a longer lifespan compared to traditional car batteries, which means that they need to be replaced less frequently. This reduces the amount of waste produced and helps to conserve resources.

Recyclability

AGM batteries can be recycled, which means that they can be repurposed and used again once their lifespan is over. This helps to reduce waste and conserves resources.

Reduced greenhouse gas emissions

Using AGM batteries can also help to reduce greenhouse gas emissions. The production of traditional car batteries requires a significant amount of energy, which can contribute to greenhouse gas emissions. AGM batteries, on the other hand, are produced with fewer greenhouse gas emissions and are more energy-efficient to use.

In summary, the lack of harmful lead and acid, reduced waste, recyclability, and reduced greenhouse gas emissions of AGM batteries all contribute to their environmental benefits. These factors make AGM batteries a more sustainable and responsible choice for vehicle owners.

AGM Car Batteries Pros & Cons

So I have covered the four main benefits that you get when it comes to AGM car batteries. But what about some of the pros and cons of these types of batteries?

Well, that is what I will give you in the table below.
