What should I consider when buying an AGM battery?

The AGM battery has some advantages over the conventional battery. When buying the battery, pay attention to the following things:

The shape of the housing

Ideally, the case of the AGM battery is similar to the old one. Something smaller is excellent, but the situation may not be more significant. In the worst case, it no longer fits the opening in the car. That costs money and time. Changes in the area of the engine should generally be left to a professional. In the engine compartment, all components must be matched to work smoothly while driving. This also applies to batteries. Therefore, the car battery should match the size of the car.

Capacity and cold test current

Another factor is the capacity of the battery. This is always measured in Ah for the battery. In general, the more capacity an AGM battery can have, the longer it will work without being recharged. Nevertheless, it is no problem to use a battery that has 10% more Ah than the old battery. Larger values influence the engine. On cold days, the cold test current becomes essential. This should be relatively high since it starts in the winter and does not always work smoothly, especially with diesel vehicles. Each battery should have a cold test current of 250 to 850 A for this reason. Higher quality batteries come on average with 550 to 680 A, therefore. Cheap models are below this value.


Ultimately, the price decides whether the AGM battery is purchased or not. But quality costs its price. After all, you want to have a reliable battery for several years. Even with AGM batteries, you should not save money. If you still want to save money, you can get the best price from your favorite battery through different price comparison sites.

Frequently Asked Questions

What is an AGM battery?

The so-called AGM battery is the latest advancement of lead-acid batteries. The AGM battery is, in principle, a lead-acid battery, in which the electrolyte is bonded to the fleece of glass fibers. The common market name is VRLA-AGM. Like gel batteries, they are welded battery cases that can not be opened. These can only drain excessive working pressure. This pressure is approximately between 20 and 200 millibars. At excessive force, the discharge channel is used. For extra safety, back-up protection has been integrated at the end of the battery so that the outside fire can not cause an explosion of the housing. Translated, AGM means something like an “absorbent glass mat.” With conventional batteries, the acid slides back and forth. In this technology, the sulfuric acid is strung in several layers and connected vertically. Since the battery is not accessible from the outside, it is considered to be deficient maintenance. A liquid does not need to be refilled. Even with shocks or blows, no fluid escapes from the housing — a significant improvement over the old VRLA battery.

What is an AGM battery needed for?

One reason is the further development of the cars. Nowadays, there are more and more vehicles equipped with a start-and-stop system. The engine will be needed again only if the traffic continues. All you have to do is hold the clutch and press the start button, and the car will start again. Especially in the city center, this has numerous advantages. Not only does it consume less power, but it also saves up to 15 percent on fuel, according to ADAC. The constant switching on and off brings with it a disadvantage. The battery is much more charged than conventional batteries. Especially for starter batteries. That’s why AGM batteries are used. These can take up to thousands of charge cycles without damage. Some batteries can even charge sunlight. However, AGM batteries cost more than conventional batteries.

How does an AGM battery work?

As mentioned above, the AGM battery is a particular type of lead-acid battery and is characterized by some different features. All cells are built in the same order. Inside the battery is usually a liquid and two dissimilar metals. Electrolyte causes a reaction of the two metals. As a result, there is an exchange of electrons. In the exchange arises, among other things, chemical energy. To use this energy, the battery must be connected to an electrical consumer. Only then make the electrons move and develop electrical power. This also creates heat energy. Not for nothing are devices such as the TV with prolonged use warm to hot. With the battery technology, a distinction is made between the closed and closed systems. In the restricted version, the liquid can be filled up with distilled water. This is made possible by openings on the housing of the battery. They are deficient maintenance and are characterized by a long service life. Stay lead-acid battery is a particular type of closed system. The electrodes consist of lead dioxide as well as lead and the electrolyte. This combination allows the AGM batteries to last a long time and use less energy.

What types of AGM batteries are there? Where are the differences?

Not every AGM battery can have the same features. It’s more of a feature that comes with the conventional battery. A distinction is made between the AGM starter battery and the AGM utility battery. The exact differences are explained below. AGM starter battery As mentioned above, the starter battery is mainly used in the start and stop systems. It is a pure starter battery, which has been made more cycle resistant using AGM technology. Only this will allow the battery to take no damage. Otherwise, the constant stopping and starting at traffic lights would be the death sentence for every car battery. Also, they are compared to the supply battery, the cheaper AGM variant. Due to the increased cycle stability, the battery can also be used as a hybrid. It can be integrated not only in the start and stop systems but also as a supply battery. Above all, mobile home manufacturers offer these hybrid batteries but use them as a pure supply battery. The difference lies in the thickness of the lead plates. Conventional batteries have a thin cross-section to deliver a lot of power in the short term. Good AGM batteries have different capabilities. AGM battery supply Also, the AGM supply batteries were already cut at the starter battery. This takes advantage of the deep-cycle technology of utility batteries and makes them even stronger for cycles. Benefits include more extended life and a better supply of energy. But not every AGM supply battery is the same. Some batteries make a solid impression on the outside but have disadvantages during use. Their weight can recognize high-quality AGM batteries. The more massive the battery, the better. Under no circumstances should you be tempted by cheap batteries.

What are the advantages and disadvantages of an AGM battery?

An AGM battery has some advantages and disadvantages. Which are precise, are explained below. Advantages: AGM batteries have back protection so that the fire from the outside can not cause an explosion. They are considered to be deficient maintenance. The liquid does not fluctuate back and forth, even with blows and bumps. The batteries are incredibly durable and are suitable for start and stop systems. AGM batteries use less energy and can be used in many ways. Disadvantage: Light and cheap batteries should be avoided as they are not high quality enough. Not every AGM battery is the same – a proper search is mandatory because not every type of battery behaves the same.

What are the advantages and disadvantages of buying an AGM battery online?

AGM batteries can be purchased via a stationary store nearby or online on the Internet. Both options are still used. However, the Internet offers some advantages that the local retailer cannot provide. Which of these are precisely mentioned below? Advantages: There is a much wider choice of different AGM batteries on the Internet Price comparison sites can save you money and time recessions of other customers give you a better overview of the battery Test videos and testimonials provide a good impression again Disadvantage: Delivery delays may occur Product information may differ from the original

What should I consider when using AGM batteries?

To enjoy the AMG battery as long as possible, you should pay attention to the correct handling. Conscientious care is the alpha and omega of every product. Before the first use, the battery should be fully charged once. In the best case, for 24 hours, depending on the battery. In any case, the charging characteristic must match the battery's device because lead batteries reach their full capacity only after repeated charging. Also, they have no memory effect. Therefore, the electrolyte should be energized as often as possible. Just in this way does the liquid contained remains fluid for a long time and conducts energy further. Never leave the vehicle uncharged in the garage. Dear, reload. The battery should be charged regularly even when the car is less used. This is especially true in winter. You should first remove the battery and store it at 15 degrees in colder temperatures and more extended shutdowns. It only needs to be recharged every 6 to 8 weeks. Furthermore, we recommend a regular look at the screw connection. Uneven terrain or bad roads can loosen the screws. In the worst case, there is a short circuit or failure.

What is the lifetime of an AGM battery?

As mentioned before, the lifetime of an AGM battery depends on several factors. These include temperature, self-discharge, and care. Even the charging current influences the service life. Generally, AGM batteries live between 4 and five years. With proper use, longer and less with lousy care. The presence of an AGM battery depends on the vehicle user.

Where is the difference between gel and AGM batteries?

The gel battery and the wet battery are recombinant. Under normal circumstances, they become gasses during charging. Also, both are closed and regulated by a valve. However, there is a difference between the two batteries. With the AGM batteries, the electrolyte is completely soaked in a glass mat separator, whereby the acid can not move. Therefore, damage or impact to the battery will not harm you. In the gel battery, however, the acid is mixed with silica. Although the acid is still immobile here, the AGM battery can work better under pressure. High pressure can be poorly applied in the gel battery. It shortens the lifespan enormously, as it can not withstand high pressure.

What should you look for when charging the battery?

In order not to damage the AGM battery, you should pay attention to certain things during the charging process. 1. The charger should be placed as close as possible to the power outlet. Also, the site must be well ventilated to carry the heat energy to the outside. 2. Under no circumstances should the charger be placed on the battery. Depending on the technology, the battery may remain inside or needs to be removed. Especially with motorcycles, you can not get around an expansion. 3. Before disconnecting the battery, you should first disable all consumers. You first pull the key and then turn off the light and, for safety, the emergency switch. 4. Now, the cable is removed from the battery. The screws can also be removed. Ideal for this is a screwdriver with a plastic handle because, with metal parts, it can quickly come to a sparking spark. Also, you should first remove the ground cable.

Why does the charging voltage play such an important role?

Especially with AGM batteries, the charging voltage is of great importance. Oxygen is produced on the cells during commissioning, which is recombined by a plate. In this recombination, water is generated, which is recycled in the acid of the battery. As a result, the battery is maintenance-free and does not need to be refilled extra. Also, a seal trigger is used, which maintains the internal pressure. This prevents the gases from drying out and the cells from failing. The excessive force is vented to the outside using a valve, which in turn avoids overpressure.
