Enhanced Flooded Battery

A flooded battery made tougher. Thicker grids and a polyester scrim hold the active material on the plates, so an EFB lasts through far more charge cycles than a standard battery. It's the value choice for entry-level stop-start cars.

Is EFB right for you?

Entry-level stop-start

This type of system was designed around EFB: reliable restarts and strong cycling at a sensible price.

Mixed daily driving

Its durability handles a mix of city and highway driving with ease.

Frequent short trips

Strong charge acceptance helps put back the charge used on lots of short journeys.

Heavy electronics

For the highest electrical demand, or vehicles with braking energy recovery, step up to AGM.
