Steps

  1. Park the car in a safe spot away from traffic and set the parking brake. Turn the ignition off and open the hood.

  2. Turn off every function on the DeWalt jump starter except the light, which can stay on or off.

  3. Put on safety glasses and gloves. Find the positive and negative terminals on the car battery.

  4. Connect the red positive cable to the positive battery terminal.

  5. Connect the black negative clamp to a bare metal ground on the car, not to the battery.

  6. Check that the jump starter screen turns on. If it stays dark, press the Light button to wake it.

  7. Get in the car and start the engine as normal.

  8. Once the engine runs, unplug the black negative clamp first, then the red positive cable.

  9. Clamp both cables back onto the holder on the jump starter so it shuts itself off.

Tips and common mistakes

Keep the clamps from touching each other or any metal while the jump starter is on.

Never connect the black clamp to the negative battery terminal on a modern car.

Let the engine run for at least 15 minutes or drive a short loop to recharge the battery.

If the car still will not start, the battery or starter may be faulty, so stop and get help.

Questions

Do I need to press a power button on the DeWalt jump starter?

No. It detects the battery and turns on when you connect the cables. If the screen stays off, press the Light button.

Can I leave the jump starter connected while the engine runs?

No. Disconnect the black clamp first, then the red one, as soon as the engine starts.

Why connect the black clamp to metal instead of the battery?

It reduces the chance of a spark near battery gases and protects the car's electronics.
