AGM, short for absorbent glass mat, is a type of battery that is notorious for its high performance, sealed structure, and ability to work in extreme temperatures.

The most common problem with AGM batteries is that people have confusion in purchasing them. Although AGM batteries are often used in different machines, they are still not as common as lead batteries. That is the reason why most people are not familiar with the technicalities of an AGM battery and have difficulty in choosing between different brands and models during the purchase process.

For all of those people who find it hard to select a good AGM battery for themselves. I have reviewed top 5 best AGM batteries that one can buy with their eyes closed.

How To Pick The Best AGM Battery For Your Needs

Before you read through the reviews of the AGM batteries that I have listed later in this article, it is important first to learn some of the prerequisites of AGM batteries that you should keep in mind when selecting one for yourself.

These prerequisites will not only help you in getting a perfect AMG battery for you but will also anytime questions that you may have in your mind about these batteries.

Why do people prefer AGM batteries over lead batteries?

You might have heard people raving about how good AGM batteries are for sports cars and heavy bikes etc. Well, there are a couple of reasons why people prefer to use AGM batteries in high-performance vehicles.

The first reason is that AGM batteries are lightweight compared to lead batteries, plus they are also high performance, so they are great for high performance demanding vehicles. And the second reason is that AGM batteries are completely sealed, so in case of an accident or impact, they do not spill acid.

What should you check before buying an AGM battery?

Whenever you are buying an AGM battery or any battery in general, always check its capacity. Because once you make the purchase and then find out that the power output of the battery is less than your needs, it could be a disaster. In fact, I recommend people always get a battery that has a much bigger capacity than what they require. In this way, you do not have to change the battery if you get some additional load in the future, and also a bigger battery has a higher chance of lasting longer than a battery that just gets you through the day.

Does the reputation of the brand matter in an AGM battery?

I have talked about the importance of brand in all my previous battery reviews, and I will continue to do so in my future battery reviews as well.

The fact that you can get the same specs battery at a lower price from a knock-off brand does not mean that you are not getting a deal. If you ask me, I would always suggest you pay the extra buck and go for the brand with a good reputation. The reason for this is simple. Cheap brands often use low-quality materials in their batteries, which decreases their durability. The same case remains with AGM batteries. It might look like that you are getting a good deal by going for the cheaper brand in the beginning, but, from the experiences that I have had, they always hurt in the long run.

I am in no way advising you to go for a fancy AGM battery that costs a fortune but just telling you to buy an AGM battery from a brand that has good reviews from its previous buyers.

Can you use an AGM battery in your car?

Aside from all the places an AGM battery can be used, it can also be used in a car. In fact, AGM batteries are often used in sports cars because they perform better than lead batteries.

But if you have a normal car that can be conveniently run on a flooded battery, then I would not recommend you to complicate things for yourself by buying an AGM battery. Instead, a lead battery would be a better option because of its common availability.

How long does an AGM battery last?

AGM batteries are known for their durability. They have a rock-solid build with a minimum chance of acid spillage. But, the real question that crosses people's minds is, for how long does this structure of AGM battery operate? Actually, when it comes to the total battery life of AGM batteries, they are pretty long-lasting compared to flooded batteries. A flooded battery can last between 3 to 5 years, whereas an AGM battery can last from 6 years to about a decade. Their battery life makes AGM batteries even more rugged.

What are the advantages of an AGM battery?

What is even the point of opting for an AGM battery in the first place? To answer the question, I am simply going to leave some advantages of AGM batteries below, and then you can decide for yourself.

  • They do not spill acid in case of an impact or accident.
  • AGM batteries are lighter than flooded batteries.
  • They have low maintenance costs.
  • They perform better than flooded batteries.
  • They are rugged and long-lasting.
  • They have meager resistance inside them.

How to maintain an AGM battery?

After buying and placing an AGM battery, the next big question that comes to one's mind is how to maintain it properly? And, believe me, the better you maintain an AGM battery, the more years it will last.

The good news is that it is, in fact, relatively easy to maintain an AGM battery. All you have to do is keep the battery in a dry place with a normal temperature. And if you are planning to keep the battery idle for more than a month, then you should at least recharge it once in a while, or it will go bad.
