Start-stop systems demand far more from a battery than conventional ignition cycles – repeated micro-cycling, rapid recharge windows and sustained auxiliary loads place conventional lead-acid technology under significant strain. The Lucas LF057 Fusion AGM battery is engineered specifically to meet these demands, delivering dependable cold-start performance and deep-cycle resilience for modern vehicles equipped with start-stop and regenerative braking systems.
As part of the Lucas Fusion AGM range, the LF057 employs Absorbent Glass Mat construction, in which the electrolyte is suspended within a tightly wound glass fibre separator. This design eliminates free acid, improves vibration resistance and enables the higher cyclic stability and accelerated recharge characteristics that advanced energy management systems require. The technology is purpose-built to work in conjunction with regenerative braking, accepting charge rapidly during deceleration phases and sustaining repeated engine-off and restart sequences without capacity degradation.
The LF057 is rated at 12V with a 45Ah capacity (C20) and 320A Cold Cranking Amps (EN). Physical dimensions are 236mm × 125mm – 220mm (L × W × H), with a B24 case classification, Terminal Type 3 and Polarity 1 (positive terminal right). Hold-down type is B00. This battery cross-references directly to the 057AGM fitment code, making it a straightforward like-for-like replacement in compatible vehicles.
The LF057 is available as part of a broader Lucas Fusion AGM and EFB range. Related SKUs include LF027, LF012, LF053, LF054, LF055, LTS16CLB and LTS51913, covering a range of capacities and fitments across the Lucas Automotive portfolio.
The LF057 is backed by a 3-year warranty, providing assurance of product quality and long-term performance in the intended application.
Standard delivery: 1–3 working days within UK mainland. 30-day returns.
The Lucas Fusion AGM & EFB battery ranges feature even higher cyclic stability and recharge more quickly than conventional lead-acid batteries. These characteristics are essential, especially when it comes to advanced systems which employ regenerative braking and other fuel-saving technologies.
Key Feature:Suited for passenger cars, balancing reliable cold-cranking performance with long service life for daily use.
