EFB batteries

Mid-tier upgrade over standard flooded — better cycling for entry-level start-stop.

When should you choose Enhanced Flooded Battery?

Choose EFB for entry-level start-stop vehicles without regenerative braking. It cycles about twice as long as standard flooded, at a lower cost than AGM. Browse AGM, EFB, flooded, gel and lithium options →

Comparison of battery chemistries by best use, cycle life, start-stop suitability and relative cost.
Chemistry	Best for	Cycle life	Start-stop	Relative cost
Flooded (SLI)	Older vehicles, standard starting	Baseline	No	$
EFB	Entry start-stop, no regen braking	~2× flooded	Entry	$$
AGM	Advanced start-stop, regen braking, high loads	~3× flooded	Yes	$$$
Gel	Deep-cycle: solar, mobility, leisure	Longest lead-acid	n/a	$$$
Lithium (LiFePO4)	Deep-cycle, marine/RV house, weight-critical	Highest (2,000+ cycles)	n/a	$$$$
