When are jump starters used and what is the right way to use them?

When it comes to older cars or vehicles, the age of the battery is one of the main reasons that a car won't start up anymore. But modern vehicles are also frequently affected by discharged car batteries as a result of their complex electronic equipment. The large number of small electrical consumers place a heavy load on the vehicle battery as a whole. Additional factors such as cold, heat, long downtimes or regular short journeys contribute to further discharge of the installed battery. This means that there is not enough energy in the car battery to start the engine. In this case, you need a vehicle-independent battery jump starter. Our straightforward, powerful jump starters provide reliable and rapid assistance for a smooth engine start. Using the powerful installed battery and two integrated jumper cables, the correct way to jump-start a car is as follows:

• Connect the positive terminals: Connect the red cable on the booster or power bank to the positive terminal of the dead battery.
• Connect the negative terminal with the earthing point: Connect the black cable (always) to a stable, unpainted metal part in the engine compartment of the receiving vehicle.
• Now switch on the booster. On our Noco jump starters, the ! must be activated for totally discharged batteries.
• Switch on electrical consumers: On the receiving vehicle, also switch on electrical consumers such as fan or rear windshield heating. This prevents harmful voltage peaks.
• Start the engine in the receiving vehicle and let the engine run.
• Now disconnect the jumper cables that were connected in the receiving vehicle: First the black cable, then the red cable.

What needs to be considered when buying a jump start battery booster?

Our professional jump starters can be differentiated according to the kind of battery or power bank installed. Of course, all jump starters feature a stable and resistant housing, high-quality cables and insulated battery clamps. We pay particular attention to long-term quality. The devices feature lead gel batteries or lithium batteries. Neither of these two battery types have a memory effect, which means they can be charged at any time. It is even recommended to recharge the battery booster after every jump-start in order to have full capacity at all times. The boosters are charged at 230V or 12V. When fully charged, the devices switch to battery-saving conservation mode. Our classic portable battery jump starters are battery boosters with a lead gel battery (AGM battery). These special lead-acid batteries are mechanically robust and can be charged at any time without a memory effect. This is a reliable battery technology that has proven effective over the course of many years. Since then, the development of battery technology has advanced considerably. The latest devices with lithium batteries such as lithium ion batteries or lithium iron phosphate batteries offer significantly higher battery capacities in much more compact dimensions. Normal cars are no problem for our small jump starter power banks. On the other hand, our more powerful lorry jumper cables can jump-start larger car engines with multiple litres of displacement, or they can be used as jump starters for lorries.
