S4 E42 Bosch Car Battery 12V 85Ah Type 249 EFB - 585501080, 3 Years Warranty

Product Number: S4E42

Start-stop systems demand more from a battery than conventional vehicles require. Each engine restart places additional charge-acceptance and cycling stress on the cell, accelerating degradation in standard flooded designs. The Bosch S4E EFB 12V 85Ah Type 249 battery (SKU: S4E42) is engineered specifically to meet these demands, providing reliable cranking and sustained charge recovery across extended urban driving cycles. Bosch EFB (Enhanced Flooded Battery) technology utilises a polyester scrim integrated into the positive plate structure. This reinforcement increases active material adhesion, reducing plate degradation under the frequent partial-state-of-charge conditions typical of start-stop operation. The result is significantly improved cycle life and charge acceptance compared to conventional flooded batteries, while maintaining the robustness expected of a Bosch product. The S4E42 delivers 800A Cold Cranking Amps (EN) at 12V with an 85Ah capacity (C20), housed in a 306mm x- 173mm - 225mm case. Terminal placement is Type 0 (positive right), with a Type 1 terminal post and B01 hold-down configuration. This battery is the direct replacement for Type 249 applications and cross-references to 249EFB. Weight is 21.69kg. This product is part of the Bosch S4E EFB range.
