Q 1. What does EFB stand for and how does it differ from a standard lead-acid battery?

A. EFB stands for Enhanced Flooded Battery. It uses a polyester scrim material bonded to the positive plate, which significantly increases cyclic durability and charge acceptance compared to a conventional flooded lead-acid battery. This makes EFB technology well suited to vehicles with start-stop systems.

Q 2. What are the physical dimensions of the Lucas LE100?

A. The LE100 measures 277mm in length, 174mm in width, and 175mm in height including the terminal. It uses an LB3 case format and a B13 hold-down bracket configuration.

Q 3. What is the terminal type and polarity of the LE100?

A. The LE100 uses a Type 1 terminal layout with a polarity code of 0, indicating a standard positive-left configuration. Always verify polarity and terminal position against your vehicle's battery tray and cabling before fitting.

Q 4. What is the OEM cross-reference code for the Lucas LE100?

A. The OEM cross-reference code for the LE100 is 100EFB. This code can be used to verify compatibility with vehicle manufacturer fitment guides and parts catalogues.

Q 5. Can the Lucas LE100 be used as a replacement for the Yuasa YBX7005?

A. The Yuasa YBX7005 is listed as a similar product within the same specification bracket. However, you should independently verify that the dimensional, terminal, and electrical specifications of the LE100 match your vehicle's requirements before using it as a direct replacement.

Q 6. What warranty does the Lucas LE100 carry?

A. The Lucas LE100 is backed by a 3-year manufacturer's warranty. This covers defects in materials and workmanship under normal operating conditions. Refer to Lucas Automotive's warranty terms for full details of coverage and any applicable exclusions.

Q 7. Is there a variant of the Lucas LE100 available for different fitment requirements?

A. Yes. The Lucas LE005 (PID000138229) is an alternative variant within the same Lucas EFB product group and may suit applications where the LE100's dimensions or specification are not an exact match.

Q 8. Does the Lucas LE100 support regenerative braking systems?

A. Yes. The Lucas Fusion EFB range is designed with high charge acceptance rates, making it compatible with vehicles that use regenerative braking and energy recuperation systems, which demand rapid and repeated recharge cycles.

Q 9. What are the delivery and returns terms for the Lucas LE100?

A. The Lucas LE100 is dispatched via standard parcel delivery. Orders to UK mainland addresses are typically delivered within 1–3 working days. A 30-day returns policy applies. Please ensure the battery is unused and in its original packaging if a return is required.

Q 10. Is the Lucas LE100 compatible with my start-stop vehicle?

A. The LE100 is purpose-built for vehicles fitted with start-stop systems. You should confirm compatibility by matching the battery specification — 12V, 65Ah, 650CCA, LB3 case, Type 1 terminal, polarity code 0 — against your vehicle manufacturer's requirements before purchase.
