The Dynamic EFB range covers cars with basic start-stop, without energy recovery from braking. It was previously marketed as Blue 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.

If your car came from the factory with EFB, you can install EFB or upgrade to AGM. If it came with AGM, do not downgrade to EFB. In case of doubt, the original battery label indicates the technology alongside the capacity.
Dynamic EFB is the current name of the VARTA Blue Dynamic EFB. Covers cars with basic start-stop, that is, without energy recovery during braking.
The VARTA Dynamic EFB, with the same references and capabilities.
Enhanced Flooded Battery: enhanced liquid electrolyte battery. It has a carbon additive in the negative plate and a polyester separator that holds the active material, allowing it to withstand about twice as many cycles as a conventional starting battery.
Yes, it works without any problem and provides greater cycle resistance. The decision is usually economic, because for a vehicle without start-stop a Dynamic SLI is already sufficient.
It is indicated on the original battery label, next to the capacity. If it is no longer legible, the rule is not to go down in technology: in case of doubt, install AGM.
