Why does a car battery not start after jumping?

How do you hook up an auto jumper to your car?

Doing this protects both engines from power surges and reduces the risk of electrical shock.
Why are the jumper cables on my car not working?

Can a jumper cable be connected to a dead battery?
Connect the other end of the black (negative) jumper cable to a metal part of the dead car that is unpainted, as far from the battery as the cable will reach. This will ground the circuit and help prevent sparking. Connecting it to the dead battery carries a risk of the battery exploding.
