AGM batteries, also known as Absorbed Glass Mat batteries, are a type of rechargeable battery that is commonly used in vehicles, power backup systems, and other applications. These batteries have become popular due to their high energy density, low self-discharge rate, and long life span.
However, like most types of batteries, AGM batteries can suffer from sulfation, which is the buildup of lead sulfate crystals on their plates. This can result in reduced battery capacity and performance, as well as a shortened lifespan. In this guide, we will discuss how to desulfate AGM battery restore them to their optimal functioning state, and prolong their lifespan. So, let’s get started!
Understanding Sulfation in AGM Batteries
Sulfation is a natural process that occurs when lead-acid batteries are discharged and charged repeatedly. During the discharge cycle, sulfuric acid in the battery reacts with the lead plates, forming lead sulfate crystals.
When the battery is recharged, these crystals should be converted back into sulfuric acid and lead plates. However, if the charging process is interrupted or inconsistent, the crystals may not fully convert, leading to a buildup of sulfation on the plates. This can also occur if the battery is left discharged for extended periods.
Sulfation can significantly impact the performance and lifespan of AGM batteries. It reduces their capacity and ability to hold a charge, making them less efficient in powering devices or starting vehicles. If left untreated, it can also cause irreversible damage to the battery, rendering it useless. That’s why it is crucial to desulfate AGM batteries regularly.
11 Best Ways on How to Desulfate Agm Battery
1. Use a Desulfating Charger:
The most efficient way to desulfate an AGM battery is by using a desulfating charger. These chargers have special circuits and modes that can break down the lead sulfate crystals and restore the battery’s performance. Simply connect the charger to your battery and let it do its job. Using a desulfation charger is the easiest and most effective method, but it can be expensive.
2. Charge at a High Voltage:
If you don’t have access to a desulfating charger, you can try charging your battery at a higher voltage than normal. This will help break down the lead sulfate crystals and convert them back into sulfuric acid and lead plates. However, be cautious when doing this as charging at too high of a voltage can damage the battery. This method may also take longer to fully desulfate the battery compared to using a desulfating charger.
3. Use an External Desulfator:
An external desulfator is a device that can be connected to your AGM battery and help break down sulfation. These devices use high-frequency pulses of electricity to disrupt the lead sulfate crystals, allowing them to be converted back into sulfuric acid and lead plates. They are relatively inexpensive, but they may not work as effectively as a desulfation charger.
4. Add Epsom Salt Solution:
Epsom salt, also known as magnesium sulfate, can help remove sulfation from AGM batteries. Mix one tablespoon of Epsom salt with warm distilled water and add it to each cell of the battery. Let the solution sit for a few hours before recharging the battery. The Epsom salt will react with the lead sulfate crystals, breaking them down and restoring the battery’s performance.
5. Use a Battery Additive:
There are also commercial desulfating additives available in the market that claim to restore AGM batteries. These additives are added directly to the battery and work by dissolving the lead sulfate crystals. However, their effectiveness can vary, and they may not be suitable for all types of AGM batteries. Using a desulfating charger or external desulfator may be more effective.
6. Perform Equalization Charging:
Equalization charging is a process where you charge the battery at a high voltage for an extended period to break down sulfation. It is recommended to do this once every few months, especially if your AGM battery is regularly used in deep-cycle applications. However, be cautious when performing this method as overcharging can damage the battery.
7. Use a Pulsed Charger:
Pulsed chargers are similar to desulfating chargers, but they use short pulses of electricity instead of a constant charge. These pulses help break down lead sulfate crystals and restore the battery’s performance. They are not as effective as desulfating chargers, but they can still improve the battery’s lifespan and performance. Using a pulsing charger can also help prevent sulfation from occurring in the future.
8. Add Distilled Water:
If your AGM battery is low on water, it may be more prone to sulfation. Check the water levels regularly and add distilled water if needed. This will ensure that the battery has enough electrolyte solution to convert the lead sulfate crystals back into sulfuric acid and lead plates during the charging process. Adding distilled water can also prevent the battery from drying out and becoming damaged.
9. Use a Battery Desulfator Plate:
A battery desulfator plate is a device that can be attached to your AGM battery to help break down sulfation. These plates use high-frequency vibrations to loosen the lead sulfate crystals, allowing them to be converted back into sulfuric acid and lead plates. They are relatively inexpensive and can be used multiple times, making them a cost-effective solution for desulfating AGM batteries.
10. Perform Manual Discharge:
If your AGM battery is severely sulfated, you may need to perform a manual discharge to break down the crystals. This involves using a high-powered resistor or light bulb connected to the battery to slowly drain the charge. Once the battery is fully discharged, recharge it using a desulfating charger or other methods mentioned above to restore its performance.
11. Prevent Sulfation from Occurring:
As they say, prevention is better than cure. The best way to deal with sulfation in AGM batteries is by preventing it from happening in the first place. Regularly maintaining and charging your battery, using it for its intended purpose, and avoiding overcharging can help prevent sulfation from occurring. This will not only save you the hassle of desulfation but also extend the lifespan and performance of your AGM battery.
Following these methods, you can effectively desulfate your AGM battery and restore its performance. It is important to regularly maintain and care for your battery to prevent sulfation from occurring in the future. With proper maintenance, your AGM battery can last for many years to come. So, make sure to follow these tips and tricks to keep your AGM battery running smoothly. Happy desulfating!
