Product Number: S4E05
Variations
Start-stop vehicles place exceptional demands on their batteries, requiring units that can withstand repeated partial-state-of-charge cycling without degradation. The Bosch S4E05 is a 12V 60Ah EFB battery engineered precisely for this application, offering 640 CCA (EN) to deliver confident engine cranking across a broad range of operating conditions.
Bosch developed the S4 EFB range using Enhanced Flooded Battery technology, which reinforces the positive plate structure with a polyester scrim to improve charge acceptance and extend cycle life compared with standard flooded designs. This construction allows the battery to recover rapidly during brief regenerative braking events and sustain the repeated discharge-recharge cycles inherent to start-stop operation, making it suitable for medium-complexity passenger cars equipped with entry-level or standard start-stop systems.
The S4E05 measures 242mm × 175mm – 190mm (L × W × H) and weighs 16.67 kg. It features a Type 1 terminal arrangement with standard polarity (terminal position 0) and a B13 hold-down configuration. The battery carries the cross-reference designation 027EFB, aligning with the widely used BCI/JASO Type 027 group size for straightforward OE replacement." This product is part of the Bosch S4 EFB range. Related variants available on site include the S4E07 (PID000138408) and S4E40 (PID000138413). "The S4E05 is supplied with a 3-year warranty, reflecting Bosch's confidence in the durability of this product under normal operating conditions.
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.

A. The Bosch S4E05 is a 12-volt battery with a rated capacity of 60Ah (C20). It delivers 640 Cold Cranking Amps measured to the EN standard, making it suitable for a wide range of petrol and diesel passenger cars fitted with start-stop systems.
A. Yes. The S4E05 is built specifically for passenger cars equipped with start-stop systems. Its EFB (Enhanced Flooded Battery) construction provides the improved charge acceptance and cycle durability required to support repeated engine-off and restart events, as well as the electrical loads associated with modern in-vehicle systems.
A. EFB stands for Enhanced Flooded Battery. It is a reinforced wet-cell design in which the positive plate is supported by a polyester scrim material. This improves mechanical stability during cycling, increases charge acceptance during regenerative braking, and extends the battery's service life under the partial-state-of-charge conditions typical of start-stop operation. It represents a step up from a conventional flooded battery but does not require the specialist charging infrastructure of an AGM unit.
A. The S4E05 measures 242mm in length, 175mm in width, and 190mm in height including the terminal. It weighs 16.67 kg. Please verify these dimensions against your vehicle's battery tray before ordering to confirm fitment.
A. The S4E05 uses a Type 1 terminal arrangement with standard polarity (terminal position 0, meaning the positive terminal is positioned to the left when viewed from the front of the battery). The hold-down configuration is B13. Confirm these specifications match your vehicle's requirements before purchase.
A. The S4E05 carries the cross-reference designation 027EFB, which corresponds to the BCI/JASO Type 027 battery group. This makes it a direct EFB replacement for vehicles specifying a 027-type battery. Always cross-reference against your vehicle's original equipment specification or owner's manual to confirm suitability.
A. The Bosch S4E05 is supplied with a 3-year manufacturer's warranty covering defects under normal operating conditions. Retain your proof of purchase, as this will be required to support any warranty claim.
A. If your vehicle originally specified an EFB battery, the S4E05 is the correct technology tier for replacement. Fitting an EFB where an AGM battery was originally specified is not recommended, as the vehicle's battery management system may have been calibrated for the higher performance characteristics of AGM technology. Consult your vehicle handbook or a qualified technician if you are uncertain of the original specification.
A. Yes. Related variants in the S4E EFB range available on this site include the Bosch S4E07 (PID000138408) and the Bosch S4E40 (PID000138413). If you require a different capacity or fitment, please use the product search or contact our team for guidance.
A. The S4E05 is dispatched via standard parcel service. Standard delivery: 1–3 working days within UK mainland. A 30-day returns policy applies. Please ensure the battery is unused and in its original packaging to be eligible for return. Contact our customer service team for full returns guidance.
