Product Number: S4E40
Variations
Start-stop vehicles place exceptional demands on the battery: repeated engine restarts, sustained electrical loads from infotainment, climate control, and safety systems, and reduced charging time during short journeys all accelerate conventional battery degradation. The Bosch S4E40 addresses these conditions directly as a 12V 65Ah EFB battery engineered for passenger cars equipped with start-stop technology.
Bosch's EFB (Enhanced Flooded Battery) technology reinforces the positive plate with a polyester scrim, increasing the active mass stability and cycle life compared to a standard flooded battery. This construction allows the S4E40 to deliver a consistent 650A Cold Cranking Amps (EN) output across a broader temperature and state-of-charge range, ensuring reliable engine starts even when multiple electrical consumers are simultaneously active.
The S4E40 measures 232mm × 173mm – 225mm (L × W × H) and weighs 16.93kg. It uses a Type 1 terminal configuration with standard polarity (Terminal Placement 0) and a B00 hold-down, making it a direct fitment replacement in applications specifying a 005-type battery. The Bosch part reference is 0 092 S4E 400; the cross-reference code 005EFB may be used to verify compatibility with vehicle manufacturer fitment guides.
This product is available in two further variants: S4E05 (PID000138407) and S4E07 (PID000138408), allowing selection across different capacity and fitment requirements within the S4E EFB range.
The S4E40 is supplied with a 3-year warranty. Standard delivery: 1–3 working days within UK mainland. 30-day returns.
The Bosch S4 battery with EFB technology is tailored to the requirements of passenger cars with start/stop systems. It ensures a safe start - even when many electrical consumers in the vehicle are in operation. EFB technology (Enhanced Flooded Battery): Positive plate coated with polyester scrim provides additional support for the active material and high cycle stability. Longer life and twice the cycle life of conventional starter batteries. Safe starting even at extreme temperatures and high number of electrical loads. Particularly good charge absorption and high short-distance resistance. Absolutely maintenance-free and leak-proof.
Key Feature:Suited for passenger cars, balancing reliable cold-cranking performance with long service life for daily use.

A. The S4E40 is purpose-built for passenger cars fitted with start-stop systems. Its EFB construction is specifically engineered to withstand the high cycle demands of repeated engine restarts and sustained electrical loading typical of modern start-stop vehicles.
A. The battery measures 232mm in length, 173mm in width, and 225mm in height including the terminal. It weighs 16.93kg.
A. The S4E40 is rated at 650A Cold Cranking Amps to the EN standard, providing reliable engine starting performance in cold and low charge-state conditions.
A. The S4E40 uses a Type 1 terminal with standard polarity (Terminal Placement 0, positive terminal on the left when viewed from the front). The hold-down type is B00.
A. The primary Bosch part number is 0 092 S4E 400. The battery type cross-reference is 005EFB. The SKU on this listing is S4E40 and the EAN-linked reference is 565501065.
A. Yes, provided the vehicle's battery management system specifies EFB technology. Fitting a standard flooded battery in a start-stop application is not recommended. Always verify the replacement technology type in the vehicle owner's handbook or with the vehicle manufacturer.
A. EFB stands for Enhanced Flooded Battery. The positive plate is reinforced with a polyester scrim that stabilises the active mass, improving resistance to the plate degradation caused by partial state-of-charge cycling. This extends cycle life significantly compared to a conventional flooded battery, making EFB suitable for start-stop applications.
