EFB batteries

Looking for a battery for a car with Start-Stop? On our Start-Stop batteries page you can compare AGM and EFB from Varta, Exide and Tudor by capacity and price.

EFB (Enhanced Flooded Battery) batteries are the reinforced evolution of the conventional flooded battery: thicker plates and additives built for the constant restart cycle of entry-level start-stop systems. Up to twice the cyclic endurance of a standard battery at a lower price than AGM.

  • Cars with basic start-stop (no regenerative braking)
  • Urban driving with many starts per day
  • Upgraded replacement for conventional batteries
  • Taxis and urban fleets

By application

What is the difference between EFB and AGM?

Both are start-stop technologies, but AGM handles more cycles and higher electrical demand (regenerative braking). EFB covers entry-level systems at a lower cost. Rule of thumb: always replace with the same technology or better.

Can I fit an EFB in a car without start-stop?

Yes. It is an upgrade: it withstands more cycles and short trips better than a conventional battery, for a small premium.

Does my car have EFB from the factory?

Check the label on the current battery (EFB/AGM) or search by number plate in our finder: we tell you exactly which technology your vehicle requires.

How long does an EFB battery last?

4 to 6 years in normal use. In intensive urban start-stop driving its reinforced design outlasts a conventional battery.

This engine comes with an AGM/EFB battery as standard: the car's charging system requires it even without Start-Stop. If in doubt, message us and we will confirm.
