How Thick Should Jumper Cables Be for Cars?

[AaliyahRose]

For ordinary family cars, cables with a cross-section of 10 square millimeters or more are required, while large trucks need cables around 25 square millimeters. Here are some precautions regarding car jumper cables: 1. 10 square millimeter cables are generally sufficient for car jump-starting: However, it is essential to use dedicated car jumper cables to ensure the success rate of the jump-start and avoid damaging the battery. 2. The correct sequence for disconnecting jumper cables: First, disconnect the black clamp connected to the charged vehicle, which is the negative terminal, then remove the black clamp from the originally dead vehicle. Next, disconnect the red positive clamp from the charged vehicle, followed by removing the red clamp from the originally dead vehicle. 3. Considerations when purchasing cables: Jumper cables that are too long can lead to power loss, potentially preventing the car from starting. It is generally recommended to use jumper cables that are 3-4 meters long. Additionally, it is important to choose high-quality cables.
