How to Connect Two Car Batteries for Jump Starting?

[GriffinLee]

Here are the steps for connecting two car batteries for jump starting: 1. Always identify the positive and negative terminals correctly - red is positive, black is negative. First, connect the red clamp to the positive terminal of the charged battery, then connect the other end to the positive terminal of the dead battery. 2. Next, connect the black clamp to the negative terminal of the charged battery, then connect the other end to the negative terminal of the dead battery. After this, you can start the car. Once the car is running, first remove the negative clamp, then remove the positive clamp. Note that the batteries must be connected in parallel, not in series. 3. Parallel connection maintains the battery voltage at 12V, which meets the voltage requirements of the engine and car control circuits. If connected in series, the battery voltage would exceed 12V, which could potentially damage the components of the car's control circuits. The starter motor would have to withstand extremely high voltage with low current, which is not conducive to the car's starting requirements.
