Should you find that you've left the lights on overnight or you’ve tried to start your vehicle and it won’t crank, you probably have a dead battery. A simple jump-start may be all that you need to get the vehicle restarted.

Here’s a couple quick tips to follow should you find yourself in need of a jump.

Do: Do make sure the jumper cables you have are in good condition. Check for frays, tears or anything that looks suspicious. If you’re even slightly concerned, use another set.

Don’t: Do let the cables dangle from your car. If they are connected, they have a charge. If that charge hits a puddle, you could be electrocuted. If the cable drops down toward your fender, it could cause a spark or fuse to it.

Do: Do make sure to attach the cables to the proper terminals. Connect the red (+) positive clamp to the red (+) positive post of the dead battery and donor car battery. Connect the black (-) negative battery clamp to the donor car’s black (-) negative battery and the other to a large, unpainted metallic part of the dead car’s engine block. Connecting the second clamp to the (-) negative post could lead to sparking, which could cause the hydrogen gas from the battery to ignite and possibly explode.

Don’t: Don’t keep attempting to start your car once it’s been jumped. There could be a much bigger underlying issue, and you should contact an automotive professional.
