Consequences of the wrong battery

Start-stop technology is a sophisticated technology, which enables cost savings for drivers and importantly environmental benefits. However, the benefits of the start-stop technology involve an increased load on the battery. Start-stop can switch off the engine at every time the car comes to a stop and start it again when the accelerator is pressed or the brake released.

When Start- Stop is active, say waiting at traffic lights, the large number of electrical consumers still have to be supplied with electricity. The radio is on, a smartphone is being charged, and the air conditioning continuously provides the necessary cooling in the car. In spite of this, the engine must still be started by the battery when the traffic light turns green. To meet these requirements, innovative batteries have been developed especially for use in vehicles with automatic start-stop systems. The wrong battery ultimately could lead to unwished consequences.

A conventional starter battery cannot meet the demands of a vehicle with an automatic start-stop system. This is true both for cars with simple start-stop systems and EFB batteries as well as for vehicles with advanced start-stop systems. These vehicles which are equipped with recuperation, the electricity which is generated by the braking process is stored in the AGM battery.

In Europe, there are about 30,000 different models of vehicles, so that it is impossible to know which the right replacement battery is for each of these models. The VARTA Partner Portal provides partner workshops with assistance in this decision, with battery positions, battery selections and installation instructions for almost all vehicles which are in use in Europe. For end customers, the VARTA battery search is an ideal tool to find the right battery.
