Is the negative on a battery a ground?
The negative terminal is never called ground. If you connect the positive terminal to the ground, the negative terminal is now at a potential of -1.5 volts.
When to ground the negative clamp when jump starting your car?
This is why most people clamp onto the frame for the last connection (which should be ground on the donor car). That’ll also be the first connection you remove, so again, no sparks near the battery. To piggyback a bit: does anyone know of documented cases of this sort of explosion occurring in the real world?
What should I do if my car JumpStart does not match?
If they do not match, serious damage can occur to both vehicles. Park the cars close enough for the cables to reach, but they should not touch. Turn the engine off in the car with the good battery. Unplug any accessories (like cell phone chargers); the power surge generated by the jumpstart can short them out.
How do you jump start a car battery?
This is the last connection you need to make. Start the car with the charged battery. Wait one or two minutes and try to start the car with the dead battery. Remove the black negative clamp from the ground of the vehicle needing the jump. Remove the black negative clamp from the assisting vehicle.
What are the risks of jumpstarting a modern car?
There are computers in modern cars that control the major and minor functions – jumpstarting your car can damage them. There’s a bigger risk of doing damage when you jumpstart a modern car compared with a pre-2000 model.
Is it dangerous to jump start a car?
This can be a dangerous myth, especially if you frequently drive in rural areas. Your car battery will not fully recharge after a jump start, even if you drive around for hours. A jump is only a temporary fix until you can replace or connect the battery to a charger.

How to jump start a fully charged car battery?
Connect one end of the red (positive) jumper cable to the red (+) positive post of the dead car battery. Connect the other end of the red (positive) jumper cable to the red (+) positive post of the fully charged car battery. Connect one end of the black (negative) jumper cable to the black (-) negative post of the fully charged car battery.
Where does the Jumper Cable go when jumping a car?
Just to make it clearer: if you follow the ground cable from the dead battery of the car to be jumped, you’ll see that it connects the battery to nothing other than the chassis of that car. Clamping the jumper cable to the chassis simply does what the dead battery’s cable was doing already… but further away from the battery.
