Selecting the correct leisure battery demands an honest assessment of your sustained power requirements – particularly where mains hook-up is unavailable and deep-cycle resilience is essential. The Numax XV31MF is a 12V 105Ah standard-technology leisure and marine battery engineered to meet the steady, prolonged discharge demands of caravans, motorhomes, narrowboats, and leisure vessels. It delivers a reliable reserve capacity for auxiliary loads without the voltage instability that undermines sensitive onboard equipment.
Built to Numax's XV-series specification, the XV31MF employs a robust lead-acid plate construction with a calcium-enhanced alloy designed to reduce self-discharge and extend cycle life under the variable charge regimes typical of leisure applications. With a Cold Cranking Amp rating of 740A (EN) and a Marine Cranking Amp rating of 925A, the battery also supports engine-start applications aboard marine craft where dual-purpose performance is required." The XV31MF measures 330mm × 172mm – 239mm (L × W × H) and is housed in a GR31 case. It features dual terminals and is supplied with positive polarity (Layout 1). Verified weight is 23.2kg. No direct cross-reference SKUs are listed; suitability for start-stop applications is not confirmed – please refer to the product label. "The XV31MF is available as part of the broader Numax XV leisure range, which spans multiple capacities and case sizes to suit differing power budgets and installation envelopes.
This battery is backed by a 2-year warranty, providing assurance of manufacturer support across its expected service life.
