Recondition A Car Battery That Won’t Hold Charge At Home

Safety Precautions You Need to Consider

First and foremost, let’s talk about safety. When working with batteries, it’s important to take precautions to avoid injury and damage to the battery and your vehicle. Then Make sure to wear gloves and eye protection, and work in a well-ventilated area.

Now that we’ve covered the safety precautions, let’s move on to the tools and materials you’ll need to recondition your car battery.

Tools and materials needed

To get started, you’ll need a few tools:

• Gloves
• Eye protection
• Clean cloths
• Distilled water
• A battery charger
• A multimeter
• A wrench

Now, let’s talk about how car batteries work. Most car batteries are lead-acid batteries, which use a chemical reaction to produce electricity. Over time, this reaction can cause the buildup of lead sulfate on the battery plates, reducing their ability to hold a charge.

Before we dive into the steps & different Methods, I want to give you a quick recommendation that I think could be helpful for you. If you want to take your battery reconditioning skills to the next level, I highly recommend checking out The EZ Battery Reconditioning Course. It’s a comprehensive guide that will teach you everything you need to know about reconditioning all types of batteries, not just car batteries.

Steps to Recondition a Car Battery

To recondition a car battery that won’t hold charge, here is a step-by-step guide that you can follow:

1. Check the Battery

Inspect the battery for physical damage, leaks, or other visible issues. If the battery is severely damaged, reconditioning might not be possible, and it’s safer to replace it.

2. Clean the Battery Terminals

Disconnect the battery from the vehicle and clean the terminals and cable connectors using a mixture of baking soda and water. Use a wire brush to remove corrosion. Clean both the battery terminals and the cable ends thoroughly.

3. Check Electrolyte Levels

If your battery is a traditional flooded lead-acid type, check the electrolyte levels in each cell. Add distilled water to bring them up to the appropriate level if the levels are low. Do not overfill.

4. Desulfation

Sulfation (the buildup of lead sulfate crystals) is a common cause of battery failure. You can attempt to break down these crystals by using a desulfating charger. These chargers send electrical pulses through the battery to break down the sulfate crystals, potentially improving the battery’s performance. Follow the manufacturer’s instructions carefully.

5. Slow Charge

Use a low amp (trickle) charger to charge the battery slowly. Slow charging over a long period (like 24-48 hours) can sometimes reverse the sulfation process. Make sure you use a charger designed for car batteries and set it to the appropriate voltage and current for your battery.

6. Load Test

After slow charging, perform a load test using a battery load tester. This will help you assess whether the battery can hold a charge under load. If the battery fails the load test, it might not be suitable for reconditioning, and you should consider replacement.

7. Recharge and Monitor

If the battery passes the load test, fully recharge it with a regular battery charger. After recharging, monitor the battery closely. If it holds the charge and continues to work well in your vehicle, it might have been successfully reconditioned.

Important Notes:

• Caution: Working with car batteries can be dangerous. If you’re not comfortable or experienced with this process, it’s safer to seek professional help or replace the battery.
• Environmental Disposal: If the battery cannot be reconditioned, it’s essential to dispose of it properly at a recycling center or an auto parts store that accepts used batteries.

Remember that reconditioning a car battery is not always successful, especially if the battery is very old or has significant internal damage. It’s often a trial-and-error process, and there are no guarantees of success, so I recommend you use Tom Ericson’s battery reconditioning guide it will help you with detailed instructions to determine if a car battery can be reconditioned or not and do it safely!

Now that you know the steps to recondition a car battery let’s dive into methods you can use to do it safely!

3 Different Methods You Can Use to Recondition Your Car Battery

Here are three methods you can use to recondition your car battery that won’t hold a charge:

• Method 1: Recondition Your Car Battery Using Epsom salt
• Method 2: Using a smart charger
• Method 3: Use a 200A charger to revive your battery. (It’s essential to note that this method can be dangerous, and your battery may explode, so let’s focus on the first two methods.)

It’s time to get your hand dirty and get an overview of what each method involve!

Method 1: Recondition Your Car Battery Using Epsom salt and distilled Water

To recondition your car battery using Epsom salt, you must follow a few steps:

Step 1: Gather your materials

• Epsom salt
• Distilled water
• A funnel
• A clean cloth
• Safety gloves and eye protection
• A battery hydrometer or voltage meter

Step 2: Remove the battery from your car.

Before you start the reconditioning process, make sure to disconnect the negative cable first, and after the positive cable. Now, you can then safely remove the battery from your car.

Step 3: Clean the battery

Use a clean cloth to remove any dirt or debris from the surface of the battery. This will ensure that you have a clear place I mean surface, for adding the Epsom salt solution.

Step 4: Make the Epsom salt solution

In a clean container, mix 2 cups of Epsom salt with 1 gallon of distilled water. Make sure to stir the solution well until the Epsom salt is fully dissolved.

Step 5: Fill the battery cells with the solution

Use a funnel to pour the solution into each cell of the battery, making sure to fill them to the appropriate level. The solution should be at the same level as the electrolyte in the battery.

Step 6: Let the battery soak

Allow the battery to soak in the Epsom salt solution for at least 12 hours, or overnight if possible. This will give the solution time to penetrate the battery and break down any sulfates that have built up on the battery’s plates.

Step 7: Check the battery’s voltage

After the battery has soaked, use a battery hydrometer or voltage meter to check the battery’s voltage. If the voltage is below 12.4 volts the battery needs more time to soak. But if it is above 12.4 volts, then the battery is ready for the next step.

Step 8: Drain the solution

Use a clean cloth to wipe away any excess solution, then use a hose or bucket of distilled water to rinse the battery. Make sure to remove all the Epsom salt solution from the battery.

Step 9: Fill the battery with distilled water

Once the battery is clean, use a funnel to fill each cell with distilled water to the appropriate level. Ensure not to overfill the cells, as this can cause damage to the battery.

Final Step: Reinstall your reconditioned car battery

Carefully place the battery back into your car, making sure to connect the positive cable first, then the negative cable. Turn on the car to test if the battery is holding a charge. Congratulations! You’ve just reconditioned your car battery using Epsom salt and it’s now ready to hold a charge like a boss!

We have done with the first method, so let’s move on to the next method: recondition a battery using a smart battery charger!

Method 2: Recondition A Car Battery Using A Smart Battery Charger

Before we dive into this method, it’s essential to have the right charger. Look for a charger that has a recondition mode, which is typically indicated by the“desulfation mode.” This mode will help to remove any buildup of sulfate on the battery plates, which is one of the most common causes of a dead battery. Ok now let’s move on.

Step 1: Gather Your Supplies
