Various types of starter battery are installed in Volkswagen vehicles: EFB/EFB+ (Enhanced Flooded Batteries) or AGM (Absorbent Glass Mat) batteries in vehicles with automatic start/stop technology and lead-calcium starter batteries in vehicles without automatic start/stop technology. Since the approved battery types vary according to model, model year and equipment, simply ask your Volkswagen Dealer about the right battery for your car. They can find it using the vehicle identification number, VIN for short.
