Purchase advice for the jumper cable comparison or test 2018

  • Starter cables are indispensable if you want to jump-start a car and should be included as standard. If you connect the jumper cable, always start with plus and then minus. If you are afraid of connection errors, a model is available that works with adapters for the cigarette lighter of both vehicles.
  • If you do not want to rely on another car with a donor battery, we recommend a jump start with its own battery. You can recharge it by using the power and then you can use it independently to jump-start yourself in an emergency.
  • You have the choice between starter cables with aluminum or copper wires. Copper is more robust and leads faster, but is more expensive and less often installed. Overall, the cable cross-section, which you should choose depending on the engine type and engine size, is more important.

The ADAC had to move out to almost four million breakdowns in 2015 (source: ADAC). In addition to real physical damage such as a broken tire or broken engine part, helpers often had to help stranded customers because the car battery was empty or too weak to start the car.

1. Not compulsory, but smart - jumper cables are standard

Well thought, done badly

Stiftung Warentest is currently unable to produce a jumper cable test, although it can report a case that clearly illustrates the consequences of incorrect wiring. An assistant incorrectly connected the starter cables, thus destroying the other car's control unit by short circuit. The insurance refused to pay the 3,800 euros, as bridging according to the court does not fall into the category of "typical use of the car".

To have a starter cable with you is not legally required, as it is the case with the first aid kit or the warning triangle, however It should be in your own interest to use the basic equipment of any car, Not everyone is a member of an automobile club or would like to dig deep in the bag to call a professional roadside assistance. Often, other helpful road users offer themselves to give your battery a jump start. If you then lack a jumper cable, the frustration is inevitable.

Always assuming that the battery is not completely broken, it does not matter if a professional or a nice private person helps you out of necessity. A jumper cable acts as a transport route for electricity, which leads it from a donor battery into the receiver battery. One speaks therefore also of the bridging cable, which usually comes in a two-piece set therefore. Both cables usually get different colors from the brands or manufacturers, so you use the same starter cable per pole connection (for example, red for the negative pole, black for the positive pole).

Insulated alligator clips protect against electric shock.

Inside, the jumper cable is filled with twisted wires. These can be made of either copper or aluminum. Depending on the material, there are differences in how well they conduct the electricity, how high their weight is and also the purchase price is influenced by it. Copper conducts faster and is more robust, but is finding less and less use because it is more expensive than aluminum.

At each end of a cable is a pair of pliers, which - similar to a grasping forceps - are clamped to the poles of the car batteries. A plastic insulation ensures that the user does not get in direct contact with the flowing current.

Cross-section: An important criterion is The cross-section of the cable, which is to be selected depending on the engine and its displacement, For petrol engines with a displacement of up to 2,500 cm³, a cable cross-section of 16 mm² is sufficient; a displacement of up to 5,500 cm³ requires a cross-section of 35 mm². For a jumper cable to master the test on a diesel engine, the cross section should be at least 25 mm².

2. Classic, with battery or as an adapter? You have these options

Whichever is the best jumper cable for you depends in part on the ease of use you expect from it. Connecting the jumper cable properly to bypass the battery can be challenging for more inexperienced users. That's why there are three types of starter cables.

A jumper cable with rechargeable battery offers you the most autonomy of its functionality, You can charge the included power storage and then use it instead of a donor battery to self-start the car.

Of course, you still have to connect the clamps, which are also called crocodile clamps, to the poles of the car battery. But they are not dependent on outside helpn, if you have paid attention beforehand to have charged the battery also by power connection and to check the level in intervals.

If you opt for a cigarette lighter jumper cable, you do not need to connect the cables directly to the poles to jump-start the car battery, This is especially recommended for car owners who are worried about making a mistake when connecting the cables to the battery, thus causing an expensive short circuit.

By plugging the adapter into the cigarette lighter of your car and the other car instead, electricity is also transferred to the weakening battery. This is much easier to operate, works on most models but only with 12 volt batteries.

Standard starter cable

The proven classic is the jumper cables, which connect you to the positive pole and the negative pole of both cars, so that the donor battery can help your weakening conspecific on the jumps. To protect yourself against electric shock, it is important to insulate the pole tongs.

Pay attention to the voltage that the jumper cables can carry. If you want to give a motorcycle a jump start, that is quite low 6 volts. If the jump aid affects a car, it can use 12 volt or even 24 volt batteries, depending on its size. Although most models cover both, a look at the technical data is worthwhile in advance.

The following graphic shows youhow to connect the two cables to the donor and receiver batteries to jump-start:

If you pay attention to the sequence of the individual steps during jump start, the engine of the breakdown vehicle should restart without any problems.

Connect correctly: The correct order when connecting the starter cables to the battery terminals is important. Proceed as follows:

  • Connect positive poles: Connect the red wire to the positive terminal of the donor and receiver batteries.
  • Connect negative pole of the dispenser battery: Then pin one end of the black cable to the negative terminal of the donor car.
  • Connect the ground point of the receiver: Now attach the other end of the black cable to the ground point of the broken-down vehicle or another metallic part of the engine block.

Danger: Under no circumstances should you connect the cable to the negative terminal of the weak battery, otherwise there is a risk of a short circuit.
