Q 1. What does EFB technology mean and how does it differ from a standard flooded battery?

A. EFB stands for Enhanced Flooded Battery. Bosch achieves this by bonding a polyester scrim to the positive plate group, which stabilises active material during repeated charge and discharge cycles. This makes the battery significantly more durable than a conventional flooded unit in start-stop applications, where the battery must restart the engine many times per journey.

Q 2. Is the Bosch S4E LE002 compatible with start-stop vehicles?

A. EFB technology is designed to support entry-level start-stop systems. However, compatibility depends on your specific vehicle's original battery specification. You should verify suitability against your vehicle handbook and confirm start-stop compatibility on the product label before fitment.

Q 3. What are the physical dimensions and weight of the LE002?

A. The battery measures 353mm in length, 175mm in width, and 190mm in height including the terminal. It weighs 24.98kg. These dimensions correspond to a standard BCI group size for larger European vehicles. Always measure your battery tray and confirm fitment before ordering.

Q 4. What terminal type, polarity, and hold-down does the LE002 use?

A. The LE002 uses a Type 1 terminal configuration with Polarity 0, meaning the positive terminal is located on the right-hand side when facing the battery from the front. The hold-down type is B13. Confirm these details match your vehicle's battery tray and cable routing before purchase.

Q 5. Are there cross-reference part numbers for the LE002 I can use to check compatibility?

A. No direct cross-reference numbers are listed for this product. To confirm compatibility, refer to your vehicle's owner handbook, consult the manufacturer's battery specification, or use a vehicle registration lookup tool on the PartsForMachines website.

Q 6. What other capacities are available in the Bosch S4E EFB range?

A. The Bosch S4E EFB range includes multiple variants to suit different vehicle specifications: S4E08, S4E10, S4E11, S4E13, S4E41, and S4E42, as well as L4034 and L4027. Each variant differs in capacity and dimensions, so select the model that matches your vehicle's original battery specification.

Q 7. What warranty does the LE002 carry and what does it cover?

A. The LE002 Bosch S4E EFB battery is supplied with a 2-year warranty. This covers manufacturing defects under normal operating conditions. The warranty does not cover damage resulting from incorrect fitment, misuse, or installation in a vehicle for which the battery is not specified.

Q 8. Can the LE002 be used in a vehicle that does not have a start-stop system?

A. Yes. An EFB battery can generally be fitted to a conventional non-start-stop vehicle provided the voltage, capacity, cold cranking amps, dimensions, terminal type, and polarity all match the original specification. In a non-start-stop application, the battery will perform at least as well as a standard flooded equivalent.

Q 9. How long does delivery take and what is the returns policy?

A. Standard delivery is 1–3 working days within UK mainland. A 30-day returns policy applies. For full terms, including any surcharge areas or restrictions for heavy items, please refer to the delivery and returns information on the PartsForMachines website.

Q 10. What are the cold cranking amps (CCA) for the LE002 battery?

A. The LE002 is rated at 850A cold cranking amps measured to the EN standard. This indicates the current the battery can deliver at −18°C for 30 seconds whilst maintaining a minimum voltage of 7.5V, making it suitable for larger petrol and diesel engines requiring high cranking performance.
