AGM Deep Cycle Batteries-Introduction, Rejuvenating And Advantages

When it’s about choosing batteries for 12V systems and appliances, the best option is to go with the AGM deep cycle batteries. AGM batteries are an excellent choice for products, such as portable fridges, light kits, inverters, and the like, which need to be worked for long periods. if you wanted to learn more about this kind of battery, then you are in the right place.

What is the AGM deep cycle battery?

AGM is the acronym for "Absorbed Glass Mat." In other words, AGM deep-cycle batteries are built differently from the standard wet, gel, or flooded batteries. The thing that distinguishes them is a chemical component presence, generally sulfuric acid, which causes a reaction that results in voltage and electricity. The chemical is absorbed by an excellent fiberglass mat, making the battery leak-proof, allowing it to be transported without any hazardous material restrictions.

We've discussed what does AGM means, but what does the deep cycle mean? The deep cycle refers to the capability of the battery to discharge and recharge for several cycles. Opposed to starter batteries, such as a car battery, which give a short burst of energy and discharge only a small part of their power, a deep-cycle battery provides a steady flow of current for a more extended period.

How do you rejuvenate AGM deep cycle batteries?

All batteries will stop working after a while, even AGM batteries. Sometimes, the age of the battery can be the cause of failure. But don't worry about it. Let's take a look at the below steps on how the AGM battery can be rejuvenated.

1. Get An AGM-Specific Charger

You will need to spend a bit on this option, as you need to buy an AGM specific charger. However, compared with purchasing a new AGM battery, it also costs less. It has desulfation steps to help recondition and recover your deeply discharged AGM battery. The charger also works with all kinds of batteries of lead-acid.

2. Do It Yourself Solution

You will need some instruments that you probably have in your garage with this option. The traditional charger you have to charge your AGM battery is tricky.

Here's what you're going to need:

● Timer or watch

● Voltmeter

● Your discharged AGM battery

● An extra battery that has more than 12.2 volts

● Battery charger under 15amps

● Jumper cables

This is what you'll do. Link the charged battery to the discharged AGM battery. Do it parallelly by connecting negative to negative and vice versa. At this stage, do not connect or turn the charger on. Attach the charger to the charged battery and switch it on.

The next thing is that the charger recognizes the battery voltage and starts charging. Wait for an hour and check AMG battery is a bit hot. If it’s too hot, then remove the charger immediately to avoid any damage.

Stop charge if the battery gases or creates a hissing sound. Check the AGM battery with your Voltmeter if all is going well. It's doing well if it reads above 10.5v. The process can take approximately 2 hours with a 10amp charger.

After reading the voltage correctly, the charger can be disconnected from the charged battery and attached to the discharged AGM battery. Now you've got an AGM battery rejuvenated.

What are the advantages of AGM deep cycle batteries?

AGM deep cycle batteries are superior in many aspects to any standard or starter battery. Here are the main advantages.

• Durable

One of the main advantages of AGM batteries is their long lifespan. An AGM deep-cycle battery, for example, will last two to three times longer than a flooded battery. The main reason that AGM batteries are so durable is that they are resistant to deep discharge. They may also be charged for 6-8 months without being used since they have an extremely low self-discharge rate.

• Safe

This battery is unshrinkable as the glass mat absorbs the lead-acids. The electrolyte does not pour out even when you transform the battery upside down. As such, the possibility of electrolyte burns is not present. Furthermore, when charged, AGM batteries don't release gas, so you don't have to worry if they are adequately ventilated during charging. They can also work well during cold temperatures, which is not the case for normal lead-acid batteries.

• More Efficient

AGM deep cycle batteries have a unique advantage: they charge up to five times faster than inundated batteries. Furthermore, the AGM technology makes an 80% discharge depth compared to flooded batteries with a 50% discharge depth to retain the same cycle time.

• Easy To Maintain

A benefit of AGM batteries is that they can be used instantly. As their cell counterparts flooded, these batteries do not need any further care, aside from recharging them before use. As a consequence, both the installation and maintenance are saved by AGM batteries for the customer.

• High-power Output

The AGM batteries have minimal internal resistance due to how they are designed. This allows them to supply sufficient power when needed, like when a battery must be started. Because of this feature, batteries better respond to charges than any other market battery.

• Sulfation Free

Sulfation is the property of batteries with lead-acid in which lead sulphate crystals are gradually accumulated in the cells. It is the cause of failures of lead-acid batteries in most cases. Sulfation happens more when the battery is not fully charged, and the crystals build up on the plates continuously. Thus, it is essential to charge them all six months to avoid the sulfation of other forms of acid batteries. Sulfation is, however, significantly reduced in AGM batteries, and they can also be stored without recharge for long periods.

And here, all you have it. Now you know everything about AGM deep cycle batteries – what they are, how to revive them, and what advantages they have.
