How To Fix A Dead Car Battery With Jumper Cables. Next plug it into the cigarette lighter point of the car. Jumping a dead battery will not fix it.
In order to charge a dead car battery a set of jumper cables and a functional car with a charged battery is required. Connecting it to the dead battery carries a risk of the battery exploding. Connect the red jumper cable to the positive terminal of the dead battery or jump start terminal on a car with a remote mounted battery.
Next plug it into the cigarette lighter point of the car.
If the plug is left unattended for hours this may top off the car battery. Yes the jump would work if it were connected to the negative terminal but if the dead battery is emitting invisible flammable gasses a spark arising from the connection could cause the battery to explode. Connect them to the directed positive and negative posts. It depends on the dead battery.
