AGM vs EFB: what’s the difference?

If your car has start-stop, the battery type matters. Here’s how AGM and EFB differ.

Start-stop vehicles

Why it matters

Start-stop engines restart many times on every trip, which works the battery much harder.

01 / EFB

Enhanced Flooded Battery

A tougher flooded battery built for entry-level start-stop systems.

02 / AGM

Absorbent Glass Mat

Built for deeper cycling and higher electrical demand, common in vehicles with advanced start-stop systems.

Replace like with like.

If your car came with AGM, stay with AGM.
