The brand
VARTA: the battery your car already came with from the factory
VARTA belongs to the Clarios group, the world's largest manufacturer of starting batteries. Its German plant produces the AGM range that comes as standard in vehicles with Start-Stop and regenerative braking energy recovery.
The commercial name of the car ranges changed in 2026 —Blue Dynamic and Silver Dynamic became Dynamic SLI and Dynamic AGM— but the references and specifications remain intact.
The range
VARTA Dynamic EFB
EFB (Enhanced Flooded Battery) is a reinforced liquid electrolyte battery: it incorporates a carbon additive in the negative plate and a polyester separator that holds the active material. The result is approximately double the cycling resistance of a conventional starter battery, at a significantly lower cost than an AGM.
The Dynamic EFB range covers cars with basic start-stop, without energy recovery from braking. It was previously marketed as Blue Dynamic EFB.
