* Epsom salt (magnesium sulfate)
* Water
* Battery charger
* Voltmeter
Instructions:
1. Prepare the Epsom salt solution: Dissolve 1/4 cup of Epsom salt in 1 gallon of hot water. Stir until the salt is completely dissolved.
2. Remove the battery from the vehicle: Disconnect the negative terminal first, then the positive terminal. Be careful not to touch the positive and negative terminals together, as this could cause a spark.
3. Clean the battery terminals: Use a wire brush to clean the battery terminals and posts. This will help to remove any corrosion that could prevent the battery from charging properly.
4. Pour the Epsom salt solution into the battery: Slowly pour the Epsom salt solution into the battery until the cells are covered. Be careful not to overfill the battery, as this could damage it.
5. Let the battery sit for 24 hours: Allow the battery to sit for at least 24 hours. This will give the Epsom salt time to work its magic and desulfate the battery.
6. Recharge the battery: After 24 hours, use a battery charger to recharge the battery. Follow the instructions on the battery charger to properly charge the battery.
7. Test the battery: Once the battery is charged, use a voltmeter to test the voltage. The voltage should be between 12.6 and 13.2 volts. If the voltage is below 12.6 volts, the battery may not be fully charged.
8. Reconnect the battery: If the battery is fully charged, reconnect the positive terminal first, then the negative terminal. Be careful not to touch the positive and negative terminals together, as this could cause a spark.
Tips:
* If the battery is severely sulfated, you may need to repeat the desulfation process multiple times.
* Epsom salt is a safe and effective way to desulfate car batteries. However, it is important to follow the instructions carefully to avoid damaging the battery.
* If you are not comfortable working with batteries, you can take the battery to a professional for desulfation.
