The battery in your car is probably going to need a “jump” at some point because it has run out of power.
This usually happens when headlights or an internal light have been left on for a long time.
It can especially quickly in the wintertime. Never done it before? Here’s a quick guide.

- Find someone with a battery under the hood of their car to jump you (some cars have batteries in the trunk. These are generally quite hard to get to.)
- Make sure someone has a good pair of jumper cables.
- Bring the two cars close together. Head to head is ideal but side-by-side is OK too.
- Make sure both cars are turned off. Put automatic transmission cars in Park, manuals in Neutral. Engage the parking brakes on both cars.
- On the batteries, look for “+” sign (red) indicator for positive, and “-” sign (black) indicator for negative.
- Attach one end of the positive cable (red) clamp to the positive terminal of the “dead” battery. Attach the other end of the positive cable to the positive terminal of the “good” battery.
- Attach one end of the negative cable to the negative terminal of the “good” battery. Attach the other end of the negative cable to the negative terminal of the “dead” battery.
- Start the engine of the good car. Allow it to run for 1-2 minutes while reving the engine slightly by pressing on the gas pedal lightly.
- Attempt to start the engine of the dead car. It may take more than one try, but do not try to restart it more than three or four times.
The dead car still won’t crank:
If the dead car doesn’t make a loud clicking sound when you turn the key, the booster cables may not have good connections. Try rocking the cable clamps slightly back and forth to get the clamps to dig into the terminals.
If the engine still won’t start, allow the good car to run for 10 or so minutes while hooked up to the dead car. Rev the engine slightly. This may build enough of a charge in the dead battery to allow you to restart. If these steps do not work after three or four more tries, stop trying to jump-start. There is probably something else that is preventing the car from starting.
