Purchase advice for the car battery comparison or test 2018

  • If the car battery is empty and can not be restarted by jump start, a new starter battery with more voltage is due. When you replace the car battery, you should pay attention to what capacity your car needs (see manual or bottom bar).
  • In addition to the classic lead battery, there are also AGM and EFB batteries. These differ mainly in terms of cold resistance and service life. Do you have a car with automatic start-stop, you tend to invest a little more money, since the low-cost lead-acid battery is not designed for this.
  • A car battery should ideally be disposed of by returning it to the dealer who sold it to you. Often they offer you a battery deposit when you buy the new battery there. However, it does not belong in the garbage, as it is a very popular part of recycling (Source: Federal Statistical Office, BMUB).

Whether your car has 70 or 200 horsepower, you've respected or ignored all your inspections, cared for the paint, or teased the seasonally-fitting tires - in the end, much more mundane things will decide whether to get your car moving. In addition to a sufficiently filled tank, especially the car battery must have enough power so that the starting process can succeed. On the way to your personal car battery test winner there are so many criteria and features to consider and we bring them closer to you in our car battery comparison 2018.

1. Nothing goes without electricity - The car battery test winner supplies many components


If you want to buy a cheap car battery, it is important to ensure that it also fits your vehicle type. Here, either the manual or a look at the previously installed battery is worthwhile, In general, however, helps the following, rough categories division:

  • Motorcycle: 6 - 19 Ah (6 - 12 Volt)
  • Small car: 36 Ah (12 volts)
  • Compact class: 28 - 50 Ah (12 volts)
  • Middle Class: 40 - 70 Ah (12 volts)
  • Transportation: 55 - 120 Ah (12 volts)
  • Truck (up to 7.5 t): 175 Ah (12 - 24 Volt)

The vehicle battery, also known as the starter battery, supplies far more components with electricity in modern cars than before. If it has always had the task of supplying the starter with the necessary power for the ignition, more and more technical components were added over the years. In addition to the air conditioning, which is a major consumer of energy, also load the radio, heated seats and various gadgets the battery under the hood. Since the best car battery can eventually fail their service and not muster enough tension.

Just for starting, it needs an electrical voltage of 100 to 1,000 amperes. Normally, a car battery can recharge if you are driving. Meanwhile, the car battery draws new energy from the alternator, which acts like a transformer, That way it can work fine for a while; Manufacturers like to cite the car battery life of their brands at five to seven years.

But things are not always that rosy. The Stiftung Warentest, which has already carried out several car battery tests, reported in 2013 on ADAC figures, according to which A vehicle battery that is too weak or completely defective is the reason for one-third of all mishaps registered in 2012 was.

What types of car batteries are there, how they differ technically and where their strengths and weaknesses lie, can be found in the following section of our purchase advice.

Connect correctly: If you want to change the car battery, it is important that you do not endanger your car. Therefore, you must know the order in which you have to disconnect the car battery, otherwise there is a risk of a short circuit. So: first select the negative pole, then the plus pole. Then connect the new car battery exactly the other way round.

2. AGM, EFB or lead - car batteries and their different types

In addition to the questions of where to get a car battery cheap or which has done particularly well in a car battery test, even the most suitable battery type is crucial, because not every starter battery is suitable for each vehicle. We clarify:

Battery Typedescription

Lead battery

Car battery comparison 2018: battery

The lead-acid battery is the standard and widely used. In its housing, which is resistant to the corrosive sulfuric acid inside, it houses several lead-acid batteries, more commonly known as wet cells, which are connected in series. The electrodes consist of lead and lead oxide, and the acid conducts electricity from one wet cell to the next.

The lead battery is so popular because he has a relatively long life, without having to be maintained or to be particularly expensive, Among its disadvantages is that outdoor temperatures below freezing can be problematic and that it can not be used in vehicles that have the start-stop system.

EFB battery

The EFB battery is on the other hand explicitly intended for motor vehicles that have installed those automatic start-stop system, It is not limited to this and can also be used in cars without this technology.

Even with this battery, it is not necessary to perform a maintenance. It also scores with even greater tolerance to minus temperatures. Apart from the higher purchase price, the disadvantages include that they can not be used in cars that use the fuel-saving recuperation technology.

In it are also wet cells, but can swing, because this type of battery was originally developed for use in motorized boats. The AGM battery is more durable and significantly less sensitive to freezing temperatures. In addition, it is also suitable for the support of the start-stop technique.

As insensitive as it is in cold temperatures, so much do her high degree numbers resist. Especially in the engine compartment, however, these arise regularly, which is why they usually can not be installed there, Thus, she retires for many car models unfortunately and is also not very cheap in the purchase price.

Cold start: Not all car batteries cope well when the outside temperature drops to the minus range. For some, the power output (also called cold-start current) decreases. How much electricity the battery is able to deliver at all, is examined in an official test procedure with DIN standard. At -18° C is measured and the higher the detected power, the better the battery performs in the cold test. You can read this value in the technical data of the battery, Especially in areas where such temperatures are likely to pay special attention to this aspect.
