How to charge a CAR BATTERY at home with this SIMPLE technique!! In this video tutorial we are going to see how we can recover any battery, be it car or motorcycle or any other battery. For this process, I am going to use 3 batteries that I had lying around the house and I am going to give them a new life. To start, I am going to measure the batteries and see. What voltage do we have with the digital multimeter and we see that all 3 are completely burst if we do not do this procedure it is practically impossible to recover these batteries for this we are going to use magnesium sulfate which some places are known as Epson salt or English salt and we are going to introduce in the holes a little sulfate and when we finish doing that we are going to use distilled water in each of the cells until we see the water at the top, we let it rest a little and then we are going to charge the batteries, in my case the batteries I'm going to let it charge from one day to the next and after that we're going to see the result, we're going to take the voltage with the digital multimeter and we're going to apply a load with a 12v bulb and see if it's able to lift it, I'm also going to connect the multimeter and at the same time I apply the load and we will see if when the load is applied if the voltage drops and if it recovers if you like the video don't forget to LIKE and subscribe thank you..
