The Lucas Fusion EFB series represents a modern approach to energy storage, designed specifically for today’s demanding automotive environments. Built with Enhanced Flooded Battery (EFB) technology, these batteries are engineered for superior cyclic durability compared to conventional flooded batteries. This makes them an ideal choice for vehicles equipped with start-stop systems, where frequent engine restarts and high electrical loads require a battery that can handle deep discharges and fast recovery. Lucas, a well-established name in the automotive sector, delivers reliability and robust performance through the Fusion EFB line, offering a balance of quality and value that meets the expectations of both manufacturers and consumers.
The Lucas LE115 is a standout model within the Fusion EFB series, featuring a capacity of 80 Ah and a cold cranking amperage of 730 A. This makes it well-suited for larger vehicles and those with energy-intensive systems. With its 315 mm length, 175 mm width, and 190 mm height, the LE115 fits perfectly within the L4 European standard battery size. The standardized terminal layout (0), terminal type (1), and B13 hold-down system ensure compatibility with a wide range of vehicles across various European brands. The LE115’s construction also guarantees a stable performance in various weather conditions, particularly in colder climates where high starting power is essential.
Being an EFB battery, the LE115 features enhanced plate design and special carbon additives that improve charge acceptance and increase the battery’s resilience to partial state-of-charge operation — a common feature in start-stop equipped cars. This makes the LE115 a more durable alternative to traditional wet cell batteries, as it can withstand over twice as many charge-discharge cycles. It’s particularly useful for drivers who frequently engage in urban stop-and-go traffic or own vehicles with regenerative braking and high energy demands.
Compared to similar batteries on the market, the Lucas LE115 holds its own impressively. It matches the Bosch S4 E11 and the Varta F22 in terms of power (80 Ah and 730 A), and shares the exact physical dimensions, ensuring that it fits where these popular models do. The Exide EL800, another EFB model, provides slightly lower cranking power at 720 A but maintains identical sizing. The Varta N80 edges ahead with a higher cranking output of 800 A, yet all models — including the Lucas LE115 — support the same vehicle applications thanks to their shared specifications and design standards.
What distinguishes the Lucas LE115 is not only its technical reliability but also the brand’s long-standing reputation for quality in the automotive industry. For vehicle owners looking to replace their original EFB battery with a model that ensures performance, durability, and compliance with OEM requirements, the LE115 is a smart and secure choice. It delivers what modern vehicles need — power, resilience, and long life, even under demanding conditions.
