Product Number: XV31MF

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."
