Now that you’ve completed the essential safety checks and gathered your tools, it’s time for the core process of how to jump start a car with NOCO Boost Plus. Follow these steps meticulously to ensure a safe and effective jump start. Precision in connecting the clamps is vital for success.

1. Prepare the NOCO Boost Plus: Before making any connections, ensure your NOCO Boost Plus is turned OFF. This prevents accidental sparking when handling the clamps. If your device has an override button for extremely low voltage batteries, do not activate it unless specifically instructed to do so by the manual for very specific, rare scenarios, as it bypasses some safety features.

2. Connect the Positive Clamp (Red) to the Positive Terminal: Take the red positive (+) clamp from your NOCO Boost Plus and securely attach it to the positive (+) terminal of your car’s dead battery. The connection should be firm and make good contact with the metal terminal, not just the plastic cover. Ensure there is no loose connection, which could cause arcing.

3. Connect the Negative Clamp (Black) to the Negative Terminal: Now, take the black negative (-) clamp from your NOCO Boost Plus. Securely attach it to the negative (-) terminal of your car’s dead battery. Again, ensure a firm, direct connection to the metal post. Some manufacturers recommend connecting the negative clamp to a clean, unpainted metal part of the engine block or vehicle chassis away from the battery. However, with modern smart jump starters like NOCO Boost Plus, connecting directly to the battery’s negative terminal is generally safe and often recommended due to its advanced spark-proof and reverse polarity protection. Follow your NOCO Boost Plus manual’s specific guidance if it differs.

4. Turn On the NOCO Boost Plus: Once both clamps are securely connected, turn ON your NOCO Boost Plus. The device will typically perform a diagnostic check. Many NOCO models feature a “Ready” light or an indicator that signals a proper connection and that the device is prepared to deliver power. Wait for this indicator. If you see an error light, check your connections again. This readiness check is a critical safety feature to confirm everything is connected correctly before power is delivered.

5. Start the Car: With the NOCO Boost Plus indicating readiness, attempt to start your car. Turn the ignition key as you normally would. If the car doesn’t start immediately, wait a few moments (e.g., 20-30 seconds) before trying again. Avoid cranking the engine for more than 5 seconds at a time to prevent overheating the starter motor. If the car still doesn’t start after a few attempts, there might be a deeper issue than just a dead battery, or the battery might be too deeply discharged for a standard jump start. Refer to the troubleshooting section or your NOCO manual.

6. Disconnect in Reverse Order: Once your car successfully starts, let it run for about 30 seconds to a minute before disconnecting the NOCO Boost Plus. This allows the car’s alternator to begin recharging the battery. Crucially, disconnect the clamps in the reverse order of connection:

   • First, remove the black negative (-) clamp from the car’s negative terminal (or chassis point).
   • Then, remove the red positive (+) clamp from the car’s positive terminal.
   • After disconnecting, turn OFF your NOCO Boost Plus.

7. Keep the Car Running: Do not turn off your car immediately after a jump start. Drive it for at least 20-30 minutes, or even longer, to allow the alternator sufficient time to recharge the battery. This helps ensure the battery has enough charge to start the car again without assistance. During this drive, avoid using excessive electrical accessories if possible.

This proactive approach ensures you’re not left stranded again soon.

Firstly, as mentioned, once your car is running, drive it for at least 20 to 30 minutes, or ideally even longer, on the highway if possible. This extended drive allows the alternator to replenish the battery’s charge. Modern alternators are quite efficient, but a completely drained battery requires a substantial amount of time to reach a healthy charge level. Short drives or idling the car for a few minutes are often insufficient and may leave you with another dead battery shortly after. During this drive, it’s advisable to limit the use of high-drain accessories like heated seats, defrosters, or powerful sound systems, as they will compete with the battery for the alternator’s output.

Secondly, and critically, recharge your NOCO Boost Plus as soon as possible after use. While it just saved you from a predicament, it likely expended a significant portion of its own charge. Keeping your jump starter fully charged ensures it’s ready for the next emergency. Connect it to a wall charger or a USB port (depending on the model) and let it charge until its indicator lights show a full charge. This preparedness is key to maximizing the utility and lifespan of your device.

Finally, consider the reason your battery died. While sometimes it’s simply due to leaving lights on, a recurring dead battery could signal a deeper issue. It’s highly recommended to have your car’s battery and charging system (alternator) tested by a professional mechanic. Many auto parts stores offer free battery testing. They can determine if your battery is still capable of holding a charge, if it needs replacement, or if your alternator is failing to adequately charge the battery while the engine is running.
