The Lucas Fusion EFB series is designed to meet the demands of modern vehicles, particularly those equipped with start-stop systems. These batteries are manufactured using Enhanced Flooded Battery (EFB) technology, providing significantly greater resistance to the repeated charge and discharge cycles experienced in urban driving. Lucas Fusion EFB batteries combine high reliability with an extended service life compared to conventional lead-acid models. They are an excellent choice for drivers who need a dependable and durable power source, especially in vehicles with intensive electrical demands and frequent engine restarts. Moreover, Lucas, with its long-standing reputation in the automotive industry, ensures that every Fusion EFB battery delivers outstanding performance under a wide range of conditions.
The Lucas LE100 is a standout model within the Fusion EFB series. It features a capacity of 65 Ah and a maximum starting current of 650 A, making it perfectly suited for mid-sized cars with start-stop technology. One notable feature of the LE100 is its reduced height of 175 mm, which allows it to fit vehicles requiring lower-profile batteries — a common requirement in many European models. Thanks to its dimensions of 278 mm in length, 175 mm in width, and 175 mm in height, the LE100 matches the standard European size H6/LB3. This size is widely used in various European cars and ensures easy installation in vehicles designed for a 278×175 mm footprint. The battery’s 0 terminal layout (positive on the right when poles face you), 1 type terminals, and B13 hold-down system make it a direct fit for many European cars without the need for additional adapters or modifications.
Because the Lucas LE100 is built using EFB technology, it is highly resistant to deep discharges and rapid recharge cycles. This makes it an ideal replacement for vehicles with energy-hungry equipment such as air conditioning, heated seats, and modern infotainment systems. In addition, the EFB construction provides improved vibration resistance and a longer lifespan compared to traditional flooded batteries, ensuring dependable starts even in harsh conditions. Importantly, only EFB and AGM batteries are recommended for vehicles with start-stop systems, and the LE100 fully complies with these standards.
When compared with similar models from other leading brands, the Lucas LE100 holds its own impressively. For instance, it matches the specifications of the Bosch S4 E07, Exide EL652, Halfords EFB 100, and Varta D54 — all of which also offer 65 Ah capacity, 650 A starting power, and identical 278x175x175 mm dimensions. What sets the Lucas LE100 apart is its combination of high performance and trusted Lucas engineering at a competitive price point. Whether you’re looking for a direct replacement or an upgrade, the LE100 is a strong contender among EFB batteries for European vehicles with start-stop technology.
