# VARTA Dynamic AUX Batteries — battery in Málaga

> VARTA Dynamic AUX auxiliary batteries for stabilizing the onboard network in vehicles with start-stop. Compact, in AGM and lead-acid.

## Description

Dynamic AUX batteries are auxiliary batteries: they do not start the engine, but power the vehicle's electronic systems when the engine is off or during the start itself.

Technology
They are compact units, in AGM or lead-acid depending on the reference, designed to stabilize the onboard electrical network. In vehicles with start-stop, they prevent the voltage drop during starting from restarting the radio, navigation system, or assistance systems. Many premium manufacturers install them as standard in an independent housing.

Applications

- Premium vehicles with start-stop and auxiliary battery as standard

- Onboard voltage stabilization systems

- Powering comfort electronics with the engine off

- Replacement of the original backup battery
