How To Jump Start your vehicle.

Learn how to safely jump start your car with NOCO Boost UltraSafe Lithium Jump Starters and keep your new driver prepared for the road. NOCO Boost is beginner-friendly and built around the same simple steps every time, so your new driver can learn it once and use it anywhere.

How To use a NOCO Boost

ATTACH CLAMPS.

Start with the positive (red) clamp, connecting it to the positive terminal on your battery. Then attach the negative (black) clamp to a chassis ground — an unpainted metal surface or bolt on the engine block, away from the battery and fuel lines. This grounds the connection safely without sparking near the battery itself.

POWER ON.

Press the power button on your Boost and wait for the LEDs to "chase." You'll see the charge lights cycle in sequence — this means the unit has detected a safe connection and is ready to go.

START VEHICLE.

POWER OFF.

Power off the device once your car is running, then remove the clamps in reverse order (negative first, positive second).

Note: If your car does not start or your LEDs do not chase, your battery may be reading under 2V, which is too low for the standard process to detect a safe connection. In this case, NOCO Boost's manual override mode can help — but use it with caution and make sure you fully understand how it works before attempting it. Instructions vary by device model, so check the manual override guide specific to your NOCO Boost.
