Enhanced Flooded Battery (EFB)

Enhanced Flooded Battery (EFB) 0
Customised to meet the requirements of cars with start/stop system: The powerful Bosch S4 E battery with EFB technology ensures safe starting – even if the vehicle operates several electrical consumers.
Features and Benefits:
  • In case of EFB technology, the positive plate is coated with a polyester scrim, providing additional hold for the active material thus keeping the self-discharge rates low: For a longer service life and double deep-cycle resistance compared to conventional starter batteries
  • Optimised active material: For reliable starting even under extreme temperatures and with several electrical consumers
  • The patented PowerFrame® (grid) for optimised current flow and less corrosion increases the cold start performance: Resulting in a particularly good charge acceptance
  • Optimised production processes: For particularly high corrosion resistance
  • The labyrinth design within the lid returns condensed water to the battery reducing water consumption and preventing sudden leaks if tilted. Eliminating the need for maintenance (100% maintenance free)
