Charging an AGM battery can be a bit tricky because you have to use the right type of charger. But, don't worry! We are going to go over what you need and how to charge it so that your battery will last for years. 

How do you charge an AGM battery?

The AGM or Absorbent Glass Mat battery is a sophisticated lead-acid battery with enhanced power and safety. The battery can be used in several different areas such as solar, marine, and automotive industries where the batteries are constantly under pressure. This battery is maintenance-free with its sealed construction, non-spillable design as well as being vibration resistant.

AGM batteries are an important aspect of keeping your electronics running, as they provide backup power for the numerous devices you need to operate throughout the day. Whether it's in a car or on our own person-to-person basis, AGMs can help us out when we need some extra juice.

The main advantage of using AGM batteries is that it can be used in any position and does not require a specific orientation to work properly.

It is critical that your AGM battery is properly charged in order to ensure it lasts a long time. The batteries will age prematurely if you charge them incorrectly. Improper charging can lead to sulfation, overcharging, and electrolyte evaporation. To avoid these issues in the future, here are some tips to keep in mind when charging your AGM batteries:

- When it comes to charging an AGM battery, there is a lot that needs to be considered. First, you should never just use any old or any type of charger on your AGM battery, or else you will damage it over time. Use the recommended charger for your specific AGM battery and make sure it is charging the right way. 

- Learn how the chargers work and how to properly use them. Chargers are designed uniquely for different types of batteries. There are several standards for charging AGM batteries, so it is best to do your research before plugging it in to avoid issues later on. In addition to this, charging instructions or procedures may differ depending on the battery manufacturer. It is indeed ideal that you are aware of how to use the specific charger that you are using.

- You should always keep an eye on your battery's temperature while charging. If it gets too hot or cold, the life of that charge will be shortened due to how damaging extreme temperatures can feel for lead-acid batteries. When charging lead-acid batteries, you should avoid doing so if the temperature is above 40 degrees Celsius. Likewise, avoiding cold weather altogether can prolong their lifespan and make sure they last even longer.

Keep these helpful tips in mind and be sure to take care of them properly to get the most out of your AGM battery's lifespan.

What are some misconceptions about AGM batteries?

The first common misconception about AGM batteries is that people thought that they can charge these batteries by using a regular charger. When charging these batteries requires the right amount of current and voltage so that it won't damage the battery. Get the appropriate charger for your AGM battery so you won't damage the cells.

The second common misconception about these batteries is that people think it can hold a charge forever and doesn't have to be charged often. Well, this isn't true, just like any other type of battery or cell needs to take care of them or else they will lose their effectiveness and last shorter.

While it is true that AGM batteries don't need to be replaced as often as other types of lead-acid batteries, they still do lose their effectiveness over time, so you need to charge them regularly, or else you will notice a decrease in the amount of power these cells can hold.

How would you know if your AGM battery is healthy?

If the AGM battery is healthy, there will be no leakage or signs of acid spills, and it is working fine. If you happen to notice leaking or any other signs of acid spilling, please do not operate the battery. The battery itself could have damage that will lead to it being ineffective. When you are trying to charge an AGM battery, always ensure that you are using a charger that has been approved for this type of battery. This way, you are preserving the life of this battery.

Some final thoughts for you to remember: If you are using the AGM battery on a boat or for other marine purposes, it is important to remember that these batteries need to be stored in dry conditions to last longer. Also, if you do not use an approved charger when charging your AGM battery, the warranty could get voided, and this will lead to your battery being damaged. Be sure to take care of your AGM battery by following the guides and tips outlined in this article so that your battery will perform at its best at all times.
