What Will Happen If I Hook Battery Cables Up Backwards
Batteries cables must be hooked up correctly when charging a battery while it is in or outside of the vehicle. The red cable is connected to the positive (+) battery terminal and the black cable is connected to the negative (-) terminal or to the car frame.
Battery to Battery
When the battery cables are hooked up with the negative to the positive and positive to the negative terminals, the battery can explode. This is true for the battery being charged and the battery in another car being used to supply the charge.
Battery Charger
A battery charger that is being used to charge a dead battery will be damaged if the positive and negative cables are hooked up incorrectly. The current to the battery charger will burn out component inside the charger.
Injury
A battery can explode when the cables are hooked up backwards. Anyone standing near the battery when it explodes could be seriously injured. Battery explosions can cause burns, permanent disfiguration and blindness.
