Marine electrical systems demand a battery that tolerates deep discharge cycles, prolonged load demands, and the corrosive environment of waterborne operation. The Numax M135 is a 12V 125Ah marine battery engineered to meet those conditions, providing a dependable power reservoir for onboard auxiliaries, navigation electronics, and cabin services across a wide range of leisure craft.
Manufactured under the Numax Standard range, this battery employs conventional flooded lead-acid technology optimised for leisure and marine duty cycles. The construction prioritises sustained energy delivery over extended periods, making it suitable for both house bank and secondary power applications where consistent capacity under moderate discharge is the primary requirement.
The M135 measures 345mm × 175mm – 210mm (L × W × H) and weighs 33.3kg, housed in an M135 case format with B00 hold-down specification and Polarity 0 (positive terminal right). Rated capacity is 125Ah at the C20 discharge rate. No direct cross-reference is listed; confirm fitment against case dimensions and terminal placement before ordering. Compatibility with start-stop systems is not confirmed – refer to the product label." No variants are currently available for this SKU. "The Numax M135 is supplied with a 2-year warranty, covering manufacturing defects under normal operating conditions.
Delivery: pallet shipment, typically 3–5 working days within UK mainland. Contact PartsForMachines for delivery quote. 30-day returns.
Choosing the correct leisure battery is all about understanding your power usage. The Numax leisure range covers all situations, applications and levels of power usage depending on what you need from your battery. Leisure battery performance is measured in cycles; these cycles are what determine their NCC rating. Battery cycles refer to the number of discharge/recharge cycles the battery is capable of when discharged by up to 50% between recharging.
Key Feature:Engineered for leisure and recreational vehicles, offering deep-cycle discharge capability and sustained energy delivery for extended off-grid power during camping or seasonal travel use.
