AGM Battery Maintenance – Charger and Procedure

AGM batteries, otherwise known as Absorbent Glass Matt is car battery. The car battery is specifically designed to run car electronics for a long time and to deliver powerful bursts of starting amps to your car. These batteries are known to have a long life span and require little effort for their maintenance.

Maintaining your AGM battery is beneficial to any car owner as it will ensure you get the best out of it, maximizing your battery's service life. It also helps ensure that you use the battery properly and even avoid misuse of the battery that may shorten its lifespanned.

Below, we look at AGM battery maintenance. We break it down to you by discussing the AGM battery maintenance charger and procedure.

AGM Battery Maintenance Charger

Adhering to the right ways of charging your AGM battery is part of maintenance. These batteries are sensitive enough to maintain their life for the stipulated lifespan requires you not to continuously overcharge and undercharge or use a non-recommended charger.

Correctly charging the deep cycle AGM battery is crucial in maintaining its performance as overcharging it can destroy or damage the internal structure of the battery. On the other hand, undercharging your AGM battery is a sure way of reducing its lifespan. To correctly charge your AGM battery, you first have to know the correct voltage. In the case of these deep-cycle AGM batteries, it is 14.7 volts.

Most times, it is advisable to use a smart battery charger when charging your AGM battery. For example, a car owner can choose to use the iTechworld 20Amp 3 stages deep cycle battery charger, a 240v smart charger. Most smart chargers will automatically detect the lifeworld type of battery being charged. It will send a pulse into the battery to determine the internal resistance and decipher the voltage that suits that specific type of battery. Smart chargers help solve the mystery of overcharging or even disconnecting the charger when you are done charging the battery. 

A car owner can also opt to use a solar panel to charge an AGM battery. any power running from the solar to the battery can leave lasting damage if not regulated. Therefore, when using solar panels, it is advisable to use a regulator to ensure that the correct voltage is consistently fed into your AGM battery. All in all, it is advised to use the manufacturer's recommended charger as every AGM battery has its own. The charger ensures the correct voltage is delivered to the battery. It also ensures no sulfation occurs.

AGM Battery Maintenance Procedure

AGM batteries are known to have a long service life unlike other batteries, that is standard flooded batteries. Therefore, these batteries require less maintenance. However, despite this, a car owner has to understand the basic maintenance requirements such as how to store the battery, sulfation prevention, and charging requirements. 

Here are some of the AGM battery maintenance procedures.

1.Storage 

Any AGM battery owner should avoid storing the battery in a discharged state as it can cause sulfation to occur. In cases where you plan to store the battery for a long time, 3 months and above, it is good to store it in a recharged state in a cool and dry place that has plenty of ventilation.

2.Prevent Sulfation

Sulfation is the process that occurs when sulfuric acid within a battery reacts and forms a lead sulfate corrosion on the battery’s negative plates. Such a reaction on the plates makes it hard for the battery to hold its charge. Therefore, as part of the maintenance procedure for your AGM battery, it is good to prevent sulfation by charging your battery before storage. In case your battery already has sulfation effects, it is recommended to disulfate the terminals using a desulfation charger. Such a charger is beneficial as it will reduce the effects of sulfation by using a reverse pulse technology which will limit the internal impedance of the battery while charging.

3.Battery Charging

Regularly check the battery’s state of charge to determine the condition of your battery. Use a voltmeter to do a routine inspection at least once every month. During the inspection, ensure the terminals and cable connections are clean and well connected.

Apart from this, just as stated above, ensure you are using the manufacturer’s recommended AGM charger for your specific battery type.

AGM Battery Maintenance-free

AGM batteries are maintenance-free which means they do not require topping up or regular maintenance checks. They are built differently to eliminate water loss once filled with acid.

The batteries are sealed as they are manufactured using fiberglass mats sandwiched between the lead plates. The fiberglass mat is beneficial as it keeps the electrolyte solution suspended in place near the active material of the plates and not flowing freely. Any gases produced during the chemical reaction within the battery will recombine with the electrolyte. Recombination of gases ensures there are no acid leaks, no mess when you are charging the battery, and no corrosion of the terminals and surrounding parts. On the other hand, excess gas that may arise from an overcharge is released via a vent within the battery to maintain the internal pressure within it.

These manufacturing characteristics make the AGM batteries maintenance-free. A car owner can store them for longer periods in an enclosed area as there is no risk of off-gassing except for the occasional one during the venting process. Therefore, such n ideal characteristics make it possible to store your battery in locations where maintenance can be tricky it hard to do.

Conclusion

AGM battery maintenance ensures you get the maximum lifespan. Its durability highly depends on how you store the batter, the charging requirements, and preventing sulfation occurrence. When it comes to charging, a car owner or anyone using an AGM battery should use the manufacturer's recommended charger to avoid undercharging or overcharging the battery. Note, the recommended chargers are different for various batteries. Therefore, only by following some of the maintenance procedures and requirements, a car owner is bound to experience a reliable and durable AGM battery.
