Which jumper cables should I choose?
When choosing jumper cables, it is important that you choose the right size to suit your specific needs. At Biltema you will find a wide range of reliable jumper cables in different sizes. Note that with jumper cables, it is not only the lengths that matter, but also the area of the cables. At Biltema we have lengths from 2.5 to 4.5 metres and cables with areas from 10 mm² to 35 mm². In other words, we offer great flexibility for different scenarios.
The length of the cable determines how easy it is to connect two vehicles, which can be crucial in tight parking spots or emergency situations. A longer cable provides more flexibility but can also be more difficult to handle.
The area of the cable is important for how much power the cable can safely transfer. A thicker cable (higher mm²) can handle higher power volumes and is better suited for larger vehicles with more powerful car batteries. Therefore, when choosing jumper cables from Biltema, base your decision on a combination of these factors to ensure you get a product that meets your needs when you need it most.
Red cable and black cable
A jumper cable set always contains a red and a black cable. The red cable is used to connect the positive (+) terminals between the two car batteries, while the black cable connects the negative (-) terminals. This colour coding helps ensure proper connection and prevents short circuits or damage to the vehicles’ electrical systems. When properly used, jumper cables enable safe and efficient power transfer from the charging battery to the dead battery.
Charge the battery after jump starting
After jump starting your battery, you should drive the car for at least 30 minutes to give the battery time to recharge. This reduces the risk of the battery dying again and needing to be jump started again.
Make sure to fully charge the battery afterwards with a car battery charger.
Note that recurring problems when starting the vehicle may indicate that it is time to replace the battery. It can also be a sign that the car’s alternator is not working properly or that the lights in the cabin or boot are not switching off.
