How Long Should You Wait Before Turning Off the Engine After Jump-Starting?

[TylerLynn]

After jump-starting the vehicle, you should wait at least 30 minutes before turning off the engine. Below are the precautions for jump-starting a car: Check the Voltage Labels of Both Vehicles: The labels are usually found on the battery tags. If the rescue vehicle's voltage is insufficient, it may not work, while excessively high voltage could damage the rescued vehicle. Pay Attention to Positive and Negative Terminals: Never reverse the positive and negative connections. Remember: positive to positive, negative to negative. Connecting positive to negative can cause a short circuit. Clamp the Positive Terminal Vertically: Do not clamp horizontally. Clamping vertically ensures direct contact with the electrode, which is made of soft lead, providing a larger contact area with the clamp. Otherwise, sparks may occur. Removing the Cables: Remove the cables one by one, not both electrodes on the same side simultaneously. Generally, the removal process is the reverse of the connection: first remove the black cable, then the red one.
