How Do I Know If my Battery is AGM or Gel? 2 Easy Methods

When you own a vehicle, whether it be a car, a golf cart, or anything else comparable, you take on the responsibility of its upkeep. Batteries are a significant component of such a system. There are several kinds of batteries available, and you may use any one of them in any one of these devices depending on the situation. When it comes to batteries, there is no such thing as a universal standard size.

Because there are several varieties of batteries to choose from, we’ll be discussing all there is to know about AGM batteries. Don’t worry if you do not know, “How Do I Know If My Battery is AGM.” When you have finished reading this guide, you will have an in-depth understanding of the AGM battery, including how to care for it, whether or not it is suitable for your vehicle, and everything else.

What is an AGM Battery?

Absorbent Glass Mat is what the abbreviation AGM stands for. This is a kind of lead-acid battery that has its terminals sealed. The technology first saw widespread use in the 1980s for the purpose of supporting military operations. The most significant issue with lead-acid batteries is the friction that they experience. Because the electrolytes are so prone to friction, the lifespan of the battery may be predicted to be shorter.

The solution was the sponge-like absorbent glass mat that was provided. As if it were a sponge made of fiberglass, it absorbs the solution of sulfuric acid and water and ensures that it is distributed evenly. As a result of the glass mats’ ability to cushion the lead plates, manufacturers are able to pack more lead and glass mats into a single battery.

How Do I Know If my Battery is AGM?

It is time to put an end to all of the uncertainty, therefore if you have a query like”How Do I Know If My Battery is AGM?” Now is the time to find the answer. Checking the kind of battery you have in your possession may often be done using any of the two methods below. We’ll go over it one by one.

First Method

The first approach is an easy one. You need to carefully read the labels that are on the battery. How can you determine if a battery is standard or sealed? What you need to know is on the label. You will notice that the labels provide you with a variety of information in a variety of formats. Stickers or labels often have the letters “AGM” or “Absorbed Glass Mat” printed on them, and they may be found affixed to AGM batteries.

It’s possible that the makers will also refer to this component as a “regulated valve”, “non-spill”, “dry cell”, or “sealed regulated valve.”
If you are having trouble locating the information, you can check the model number and the information about the maker on the internet. After making all of these queries, you should hopefully be able to acquire a response to your query.

Second Method

In order to use the second approach, you will need to search for detachable caps that have the word “sealed” inscribed on them. The Absorbent Glass Mat batteries have flat tops, which is where the positive and negative terminals emerge from the battery. If you shake the battery and the individual cells don’t move subsequently, you have either an AGM battery or a gel-filled battery.

With any of the above two methods, you will have the answer to your query, “How Do I Know If My Battery is AGM?”.

Benefits of AGM Battery

When it comes to AGM power cells, there are quite a few benefits that come along. The fact that these batteries are resistant to spilling is the primary advantage that they provide. It does not suffer any degradation in performance even when subjected to persistent vibration. The low internal resistance enables the user to make use of the device’s high power output.

In addition to this, these batteries charge more quickly than the traditional flooded technology and their life cycle is superior to the flooded systems. Its high productivity may be attributed to the reduced amounts of electrolytes and lead that are used. They have a high tolerance for the cold, making them an excellent choice when the temperature drops.

When you take into account its rapid recharging capability, high power output, and extended life cycle, this particular lead-acid battery emerges as the category’s superior option. In addition to all of these benefits, they are exceptionally long-lasting and have a lower susceptibility to sulfation.

Are AGM Batteries worth the Money?

In our view, the answer is yes, they are worthy of paying the higher price. The amount of money that consumers invest initially is returned to them many times over the product’s lifespan. In comparison to the performance of the flooded version, theirs is much superior. Because they are hermetically sealed, there is no risk of their leaking in any way. They are well worth the money due to their durability, effectiveness, and minimal required level of maintenance.

Where to use AGM Batteries?

You may utilize AGM batteries in every situation that would be suitable for lead-acid batteries. It is nothing more than an improved version of standard flooded lead-acid power cells. The performance of this power cell might be of tremendous use to automobiles as well as golf carts.

AGM batteries are compatible with a variety of other electric cars that are battery-powered. In addition to those, it has a wide variety of additional uses. An ignition power source, uninterruptible power supply (UPS) systems, starting autos, grid-scale power systems, and many more applications are included in the list of possible uses.

Frequently Asked Questions (FAQs)

Do new AGM Batteries come fully charged?

No, brand-new AGM batteries do not come with a full charge; thus, the batteries must get a full charge before being used. A brand-new AGM battery has between 75 and 80% of its capacity charged.

To begin utilizing a new AGM battery, it is necessary to completely charge the battery using a charger that has a charge rate of 12.8 volts or more before you can begin using the battery. If you want to prevent a premature failure in the battery, it is recommended that you avoid charging it at a current level that is higher than 32.72 degrees Fahrenheit.

It is possible that the voltage will increase higher than 16 volts while you are charging the new AGM battery; hence, you should verify the open circuit voltage after about one to two hours have passed. However, the producers of AGM batteries suggest that the batteries be charged for a period of at least five hours. Additionally, you should avoid charging for lengthy periods of time.

Can we use a Regular Charger to charge an AGM Battery?

No! AGM batteries are intended to be charged at a low and slow rate; hence, AGM battery chargers are constructed with microprocessors that are responsible for collecting information from the battery and adjusting the voltage and current as needed.

What Charger is the Best for AGM Batteries?

AGM batteries are intended to accept a slow and low charge and hence need specialized chargers. This is because, unlike lead-acid batteries, their chemical composition does not include electrolytes.

The chargers that are suggested are equipped with a one-of-a-kind microprocessor that helps gather information about the power components of the battery and makes the required modifications on the current and voltage to ensure that it meets the requirements of the battery.

What is the difference between Flooded and AGM Batteries?

Even though Absorbed Glass Mat (AGM) batteries, also known as dry cell batteries, and flooded/ wet cell batteries are collectively referred to as lead batteries, there are still some key distinctions between the two types of lead batteries.

AGM batteries do not need any kind of maintenance, and they include a one-of-a-kind glass mat separator inside of them. This separator helps saturate the fiberglass with electrolytes, and it keeps the electrolyte in a suspended or “dry” condition rather than in the form of a liquid.

AGM batteries do not need to have their water levels checked, and their performance is superior to that of wet cell or flooded batteries. On the other hand, they may be harmed if they are either undercharged or overcharged over an extended length of time.

Whereas flooded batteries are a mix of liquid electrolytes, and for the battery to function at its optimal level, the liquid must be precisely monitored and maintained.

The price per charge of flooded batteries is lower than that of AGM batteries.

Final Thoughts

It is time to put an end to all of the uncertainty, therefore if you have a query like “How Do I Know If My Battery is AGM?” Now is the time to find the answer. Checking the kind of battery you have in your possession may often be done using any of the two methods below. We’ll go over it one by one.
