What is the appropriate length for car jumper cables?
1 Answers
Car jumper cables are generally suitable at a length of 3 meters. Cables that are too long will increase resistance and consume power, while cables that are too short are difficult to connect. When a car battery is low on power, it can affect the entire vehicle's power supply system, making it difficult to start the car. Use 16-gauge copper wires to interconnect the battery electrodes of both vehicles, then start the other car and let its engine idle. After that, attempt to start your own car. If the issue is a low battery, the car should start quickly. After starting, keep the engine running for 15 to 20 minutes to allow the alternator to recharge the battery. If the car battery is low on power, it should be promptly charged and reactivated using a battery charger. If the charger fails to charge the battery, a high-resistance repair device can be used to raise the voltage above 10V for recovery.
