Silver Dynamic Auxiliary
Made for a dual battery system.
VARTA® Auxiliary batteries provide electrical components with seamless functionality. This enables an increase in the length of the start-stop moment and supports comfort functions during engine start. Modern cars consume a significant amount of electricity. Therefore, these cars with a combustion engine often come with two batteries: a regular 12 volt starter battery and an auxiliary battery.
Got a question?
-
Since the turn of the millennium, start-stop technology has been introduced in more and more vehicle segments and models to comply with increasingly stringent emission regulations. Nowadays, there are hardly any new vehicles that are delivered without a start-stop function. In other words, the newer the vehicle, the more likely it is to feature automated engine shutoff.
If the car is equipped with a Battery Management Sensor, it has a Start-Stop system or at least a Smart-Charging System that requires advanced battery technology such as AGM or EFB
-
For a car with a start-stop system, the recommended battery types are Absorbent Glass Mat (AGM) or an Enhanced Flooded Battery (EFB) battery.
If an AGM battery is already installed in the vehicle, it must always be replaced with another AGM battery since the vehicle's Energy Management could overstress a Flooded battery which leads to shortend battery lifetime.
