How to Recondition AGM Battery Safely

AGM (Absorbent Glass Mat) batteries are widely used in various applications, from cars and boats to backup power systems. These batteries are known for their reliability and long service life. However, like any other battery, AGM batteries also experience degradation over time. The good news is that you can recondition AGM batteries to restore their performance and extend their lifespan. In this article, we will guide you through the process of safely reconditioning AGM batteries.

Understanding AGM Batteries

Before diving into the reconditioning process, let’s first understand how AGM batteries work. AGM batteries are a type of valve-regulated lead-acid (VRLA) battery. They feature a unique design that utilizes a fiberglass mat soaked in electrolyte to hold the electrolyte in place between the battery’s plates. This design ensures better acid circulation and minimizes the risk of acid leakage.

AGM batteries are sealed, maintenance-free, and designed to provide a high level of electrical performance. They are commonly used in applications where deep cycling and high discharge rates are required. However, just like any other battery, AGM batteries can lose their capacity and performance over time due to factors such as sulfation, electrolyte imbalance, and stratification.

The Benefits of Reconditioning AGM Batteries

Reconditioning an AGM battery can offer several benefits, including:

1. Restoring capacity: Over time, AGM batteries may lose their capacity due to sulfation, which occurs when lead sulfate crystals accumulate on the battery plates. Reconditioning helps break down these crystals and restore the battery’s capacity.

2. Extending lifespan: By reconditioning an AGM battery, you can eliminate the effects of sulfation and other forms of degradation, thereby extending the battery’s overall lifespan.

3. Saving money: Replacing AGM batteries can be expensive. Reconditioning allows you to revive your existing battery, saving you money in the long run.

4. Eco-friendly: By reconditioning AGM batteries instead of disposing of them, you’re contributing to a greener environment by reducing electronic waste.

Safety Precautions

Reconditioning AGM batteries involves working with potentially hazardous materials. To ensure your safety, it is important to follow these precautions:

1. Protective gear: Always wear safety goggles, gloves, and a lab coat or protective clothing to protect yourself from chemical exposure.

2. Well-ventilated area: Perform the battery reconditioning process in a well-ventilated area to prevent the accumulation of harmful gases.

3. No open flames: Avoid working near open flames or sparks, as AGM batteries release hydrogen gas during the reconditioning process, which is highly flammable.

4. Disconnect power sources: Before starting the reconditioning process, make sure to disconnect any power sources and remove the battery from the device or vehicle.

The Reconditioning Process

Follow these steps to safely recondition an AGM battery:

Step 1: Preparation

1. Gather your tools: You will need safety goggles, gloves, a voltmeter, a battery charger, a distilled water bottle, and a battery terminal cleaner.

2. Safety first: Put on your protective gear and ensure you are working in a well-ventilated area.

3. Charge the battery: If the AGM battery is completely discharged, charge it using a battery charger until it reaches a minimum of 12.6 volts.

Step 2: Inspection

1. Visually inspect the battery: Look for any signs of physical damage, such as cracks or leaks. If you notice any damage, do not proceed with the reconditioning process, as it may pose safety risks.

2. Test the voltage: Use a voltmeter to measure the battery’s voltage. If the voltage is significantly lower than the manufacturer’s recommended level, it indicates a capacity loss.

Step 3: Desulfation

1. Prepare the desulfation solution: Mix distilled water with an equal amount of battery desulfator solution according to the manufacturer’s instructions.

2. Add the solution to the battery: Carefully remove the battery caps and add the desulfation solution to each cell. Only add enough solution to cover the top of the battery plates.

3. Charge the battery: Connect the battery charger and set it to a low ampere rate. Allow the charger to run for a few hours or as recommended by the desulfator solution manufacturer.

4. Monitor the process: Keep an eye on the battery’s voltage during the desulfation process. If the voltage exceeds the recommended level, reduce the charging rate or stop the process.

5. Recheck the voltage: After the desulfation process, measure the battery’s voltage again. If the voltage has increased, you have successfully de-sulfated the battery.

Step 4: Equalization

1. Prepare the equalization solution: Mix distilled water with an equal amount of battery equalization solution according to the manufacturer’s instructions.

2. Add the solution to the battery: Carefully remove the battery caps and add the equalization solution to each cell. Only add enough solution to cover the top of the battery plates.

3. Charge the battery: Connect the battery charger and set it to an equalizing charge mode. Allow the charger to run until the battery reaches its full capacity or as recommended by the equalization solution manufacturer.

4. Monitor the process: During the equalization process, monitor the battery’s voltage and temperature. If the voltage exceeds the recommended level or the temperature rises excessively, adjust the charging rate or stop the process.

5. Recheck the voltage: After the equalization process, measure the battery’s voltage again. If the voltage has stabilized at the recommended level, the equalization process is complete.

Step 5: Final Steps

1. Clean the terminals: Use a battery terminal cleaner or a mixture of baking soda and water to clean the battery terminals and ensure good electrical contact.

2. Reinstall the battery: Put the battery back into the device or vehicle and reattach the cables, ensuring proper polarity.

3. Regular maintenance: To maintain the reconditioned AGM battery’s performance, perform regular maintenance, including periodic charging and avoiding deep discharges.

By following these steps and taking the necessary precautions, you can safely recondition AGM batteries and restore their performance. Remember, always refer to the manufacturer’s instructions and guidelines specific to your AGM battery model for the best results.

Whether you want to extend the lifespan of a car battery or revive an AGM battery for a backup power system, reconditioning offers a cost-effective and environmentally friendly solution. Give it a try and see the difference it can make in maximizing the lifespan of your AGM batteries.
