Get started practically in 12 steps
Repairing / repairing your car battery yourself is not that difficult and you can easily do it at home.
It is important that you observe a few safety instructions.
- Always protect your hands with rubber gloves and your face and eyes with safety glasses.
- In addition, also provide protective clothing, such as an apron.
- Always work in a well-ventilated area.
- Do not smoke when working on your car and battery.
Step 1: Check whether the car and the battery have cooled completely.
Step 2: Open the hood of your car and look for the battery.
Step 3: Disconnect the cables from the car battery. Remember to always disconnect the negative cable first and then the positive cable. If you do this in the reverse order, you can seriously damage the electronic functions of your car.
Step 4: Remove the battery from your car. Make sure that you wear insulating footwear and that you do not make any contact (not even with the material you are working with) with other parts of the car.
Step 5: Place the battery in a place where you can work easily. Choose a stable, concrete surface. Certainly do not work on the battery on a porous floor. The corrosive sulfuric acid contained in the cells of the battery can seriously damage your floor. Also do not choose a sandy bottom or soil for this. Spillage of electrolyte fluid can cause irreversible soil damage.
Step 6: Open the cells of the battery and empty them. Store the electrolyte fluid in a special waste container. Do not use a metal container for this, because the sulfuric acid can attack the metal.
Step 7: Take approximately 5 liters of distilled water and dissolve 250 grams of Epsom salt in it. The Epsom salt will dissolve much faster when the water is warm. Moreover, hot water will make the revision process much faster. The Epsom salt added to the distilled water causes the crystal layer that has formed on the lead plates of the battery to dissolve. Once these hard crystals have disappeared from the plates, your battery will regain capacity, allowing it to restart your car.
Step 8: Carefully pour this solution into the cells of the battery. To avoid spillage, it is best to use a funnel for this.
Step 9: Close the cells of the battery again and let the solution take effect for about 6 hours.
Step 10: Once the liquid has completely absorbed, you can fully charge the battery for the first time.
Step 11: Discharge the battery under load. If the battery is completely discharged, fully charge it again to end the revision process.
Step 12: Put the battery back in your car and connect it. Your battery and car should do fine again!
