Dead car batteries are a major annoyance – but one that can be quickly overcome with a battery charger. Here you can find a comparison of four of the devices.

Especially in the cold season, it can happen that the engine does not start because of a failing car battery. Then you have three options:

1. You call your automobile club for help. He will then send a service car to you to help you with the battery – waiting time included.

2. You ring your neighbor’s bell and hope that he will use a charging cable to bridge the electricity from his battery for you.

3. You use your own car battery charger.

In the table below, we have compared four devices for you that have received at least four stars from Amazon. As you can see, good chargers don’t cost a fortune.

There are a few things to keep in mind when using a charger. The colleagues from “” put them together.

It is possible that the battery must be completely disconnected from the circuit before charging. Please note the information provided by the vehicle manufacturer. Especially in modern cars, the battery is usually connected to the circuit, which is why it is necessary to disconnect it from the circuit. When disconnecting, it is very important that you always first disconnect the black negative pole and only then the red positive pole.

Even before the actual charging process, there are a few things to consider: Never leave the engine running. Do not operate the ignition. Turn off the radio, lights, and all other power sources. The charger must also be switched off before connection. You can only connect the device once you have followed these instructions.

To do this, first connect the red cable to the plus point with the car battery. If the battery is still installed, then connect the black wire to the ground point of the car. Only when the battery and the charger are properly connected can you switch on the device. Otherwise there is a risk of battery damage.

Now you can start the loading process. Modern chargers usually switch themselves off when the battery is fully charged. However, it is essential that you observe the precise information in the operating instructions for the device.

For this comparison, a specialist editor from our partner examined test reports from other publications as well as the most popular offers (“best sellers”) and customer opinions from online retailers. Based on this, the product selection was made. For the selection of the top devices, models with more than four stars and a reasonably high number of ratings come into question. A selection of customer reviews was read and devices were selected that, based on the professional assessment, meet the needs of the users. The products have not been tested in the CHIP test center.

All products that the CHIP test center had in the laboratory can be found in this list of the best. Products that have also been tested by our other cooperation partners can be found in the test
