How long should I leave jumper cables on?
If your car does start, let it run for a few minutes to help charge the battery further. Unhook the clamps in the reverse order of how you put them on. Be sure to drive your car for about 30 minutes before stopping again so the battery can continue to charge. Otherwise, you might need another jump start.
What happens if you connect a jumper cable to a dead battery?
Connecting the jumper cable to the negative terminal of the dead battery can create sparks and potentially cause an explosion. You should never attempt to jumpstart a frozen battery, as doing so can cause it to explode. Remove the dead battery, bring it inside, and allow it to thaw before attempting to jumpstart the vehicle.
