Product Number: LX31
Variations
Powering leisure and marine electrical systems demands a battery that can sustain prolonged discharge cycles without compromising reliability. The Lucas LX31 is a 12V 105Ah dual-purpose leisure battery engineered to meet both starting and deep-cycle demands, making it suitable for motorhomes, caravans, narrowboats, and marine vessels where a single battery must handle engine cranking and auxiliary loads alike.
Lucas Automotive draws on decades of OE-level battery manufacturing to produce the LX31 within its Marine and Leisure range. The battery utilises a standard flooded lead-acid construction with robust internal plate architecture, delivering 740A cold cranking amps (EN) and an NCC Class B classification – confirming its suitability as a secondary or leisure battery in verified NCC-compliant installations.
The LX31 occupies a Group 31 case (GR31) with precise dimensions of 330 × 172 × 242 mm and a mass of 23.2 kg. It is fitted with Marine Dual Terminal (DT) posts, accommodating both standard automotive and marine cable terminations. Polarity is configuration 1 (positive terminal left). Hold-down type is B00. No direct cross-reference is listed; compatibility with start-stop systems is not confirmed – consult the product label before fitment.
The LX31 is available alongside related Lucas leisure variants including the LX24, LX25, LX27, LL26, LL30, and LL35, covering a range of capacities and case sizes to suit differing installation requirements.
This battery is supplied with a 2-year warranty against manufacturing defects, providing assurance of product integrity across its expected service life.
