Auxiliary Starter Batteries for Vehicles
Some manufacturers such as Mercedes-Benz, Audi, BMW, Porsche or Volkswagen equip their models with an auxiliary starter battery. This secondary battery does not directly crank the engine but stabilizes the electronic systems, manages the start-stop function and supports the main battery during peak demand.
When to replace it?
- Electrical warnings or errors on the dashboard.
- Intermittent failures of the start-stop system.
- Abnormal discharges or resets of electronic modules.
