When a car does not start because of a broken battery, you can still use jumper cables and another vehicle to start the car. When buying a set of jumper cables, it is very important to pay attention to the diameter of the cables. A diameter of only 16mm is only suitable for small petrol engines, diesel engines are heavier and therefore need a set of jumper cables with a larger diameter of 25 to 35mm. Some jumper cables are equipped with a safety device to protect the vehicle's electronics. Discover the different types of jumper cables from 16mm to 50mm below.
