4Gauge 25FT 150Amp heavy-duty battery jumper cables are made from copper coated aluminum for easy electrical conductivity and power transfer. The cable is rated to withstand temperatures of -40°C to 167°C. It has a spring loaded clamp, which ensures that it does not fall off. This makes it the best choice for those who want to save money on electricity bills. Not only this, but it also reduces noise pollution.
Booster 30 FEET JUMPER CABLES, which are made from copper-clad aluminum, provide protection to the battery of a vehicle. The cables can be used to jump start cars and trucks with ease. They come with a travel bag for easy transport and compact storage. These cables have a weight capacity of 300 watts each. It has a maximum load rating of 500 watts. The cable is designed to last for at least one year. Notably, it was launched in 2015.
Booster Cable comes with a travel bag and a pair of safety working gloves. The cable is made from copper-plated steel and has a maximum load rating of 50 kg. It can be used for cars, motorcycles, trucks, vans and SUVs. The cable weighs about 100 grams per meter and is corrosion-resistant. Not suitable for use in electric vehicles. This cable is designed to last for up to 10 years.
One of the most common problems any driver may encounter is an unexpectedly "dead" battery. Headlights not switched off in time, a solid battery age or a long stay in the cold - and already the weakened battery vainly tries to crank the starter.
The conductive element of the starter wire is the strands hidden under the insulation jacket. Most often they are made of copper - this is the most optimal material both in terms of cost and in terms of its characteristics. Copper has an affordable price and a fairly low resistance, that is, it weakly interferes with the passage of electric current and, accordingly, minimizes voltage losses.
When buying starter wire, it is not possible to determine the number and diameter of the cores: you can check the manufacturer's stated characteristics only by cutting the insulating sheath. To determine the cross-sectional area of cigarette jumper cables, it is necessary to multiply the cross-sectional area of each core by their number. In turn, the cross-sectional area of the core is found by a simple formula for calculating the area of the circle: by multiplying the number π (~3.14) by the square of their diameter and dividing by 4, we get the result.
For example, having found under the insulation 300 wires with a diameter of 0.3 mm each, we obtain that the total cross-section of the wire is: 300×0.3×0.3×3.14: 4 = 21.2 mm².
However, you probably will not have to do the math - conscientious manufacturers immediately indicate all the necessary information on the packaging or on the cable itself.
When choosing high-quality starting cables, you should choose cables with a cross-sectional area of at least 12 mm², or better - from 16 mm² and above. Such a cable will easily pass the necessary current with minimum losses - which means that it is guaranteed to help a dead battery.
Car jumper cables can only withstand a certain amount of amperes flowing through them, and this parameter is usually specified by the manufacturer. For modern cars, the absolute minimum is 200 A, and it is better to look for wires that can provide a maximum current of 400 A and above.
It is worth remembering that the current that the wire will withstand depends directly on the diameter of the wires, their number in the wire and, accordingly, the cross-sectional area. Therefore, you should understand - if an unscrupulous manufacturer has used thin, "liquid" conductors and their number is woefully small - such a wire is unlikely to withstand even 200 A, not to mention the often exaggerated 300-400 A or more.
The most common wire sets on sale are 2 to 5 meters long. Despite the fact that it seems right to choose the longest possible wire for a guaranteed connection of two batteries, you should not forget about the laws of physics: the longer the cable through which current flows, the greater the voltage loss and the higher the resistance - and therefore the lower the efficiency.
On the other hand, it is not always possible to drive up close to the hood of the damaged battery, which is especially important in urban areas (narrow streets, multi-level parking lots and busy parking lots). Therefore, for jumper cables discharged battery from another battery optimal length will be from 3 to 4 m, such as a set of starting cables Carfort (maximum current of 500 A, length 4 m), and to restore the battery at home from a special charger enough cable length of 2.5 m.
An important indicator of workmanship: First, as mentioned above, do not be fooled by the thick layer of rubber. It may hide underneath a thin bundle of wires, which will not be able to conduct the necessary current to start the starter. Secondly, the insulating material must be strong, not tan in the cold and remain flexible even at low temperatures. Therefore, high-quality wires use frost-resistant insulation that can withstand as low as -40°C without losing its elasticity.
The main working part of the starting leads are the toothed grips (also known as "crocodiles") with which the battery terminals are "clamped" according to their polarity.
Quality crocodiles have the following features:
It is undesirable to buy starting wires, whose "crocodiles" do not meet the above recommendations - the effectiveness of the jumper cable may be insufficient to start the engine.
