The Delkor Marine & Leisure M31 is a premium, high-performance dual-power battery specifically engineered to handle both heavy motor cranking and continuous auxiliary accessory loads on marine craft and recreational vehicles. Incorporating high-strength wrought grid plates and commercial-grade anchor bonding, it delivers steadfast electrical output across extended journeys and in the most unpredictable weather conditions. Housed in a durable, high-strength polypropylene case with heat-sealed covers, this fully maintenance-free battery ensures absolute safety and peace of mind on your next open-water or off-grid adventure, featuring a convenient Centre terminal alignment.

Perfect for boat and RV owners who demand:

  • ✓ Versatile dual-power capability engineered for dependable engine starting and a massive 110 Ah reservoir for sustained house electronics load
  • ✓ Superior structural integrity designed to withstand aggressive hull pounding and rough trail vibration
  • ✓ Advanced safety elements, featuring integrated spark arrestors to guard against external ignition paths

Key Features & Benefits

Dual-Power Engineering

  • • Optimised internal grid structure provides standard-setting cranking power (720 CCA)
  • • Delivers excellent semi-deep cycling capability to smoothly run continuous onboard leisure equipment
  • • Balances rapid charging acceptance with long-lasting electrical runtime delivery

Anchor-Bonded Vibration Resistance

  • • Specialised internal anchor bonding locks plate elements securely to the bottom of the cell chamber
  • • Drastically minimises active paste shedding caused by constant sea chopping or corrugated roads
  • • Wrought grid configuration provides ultimate resistance against premature mechanical plate failure

Enhanced Safety & Casing

  • • Fully heat-sealed lid covers create a robust barrier against external environmental leaks
  • • Integrated built-in safety spark arrestors protect the internal battery cells from exterior ignition lines
  • • Heavy-duty black polypropylene case defends internal structures from impact shock stresses

Maintenance-Free Conveniences

  • • Completely closed maintenance-free format means you never have to check acid levels or top up fluid
  • • Dual marine post configuration allows clean separation of main starter leads and leisure auxiliary wiring
  • • Group Size GP31HC footprint with a clean Centre terminal layout fits seamlessly into heavy-duty setups

Advantages & Considerations

Advantages

  • ✓ Versatile dual-purpose build manages both starting and continuous lighting/appliance loads
  • ✓ Anchor bonding delivers exceptional vibration durability for rugged maritime/off-road uses
  • ✓ Threaded marine terminals enable easy, rattle-free attachment of secondary auxiliary rings
  • ✓ Non-accessible sealed design ensures clean, worry-free operation without fluid checking

Considerations

  • • Engineered for dual-power marine and RV setups; not formulated or suitable for start-stop car systems
  • • Features a Centre terminal layout; check existing cable lengths to ensure easy terminal reach
  • • While highly durable, extreme solar or deep trolling loads are best served by specialised full deep-cycle models

Frequently Asked Questions

What does a "dual-power" or marine-grade application mean?

Standard car batteries are only designed for quick starting bursts, whereas dedicated deep-cycle units deliver continuous current over time. The Delkor Marine M31 is a hybrid dual-power battery. It features robust starting power (720 CCA) to crank over marine or camper engines, while simultaneously possessing thick, heavy-duty plates capable of coping with continuous accessory power draws.

Does this battery require fluid level checks or topping up?

No, this model features a premium Sealed Maintenance-Free (SMF) configuration. The advanced internal plate alloy engineering completely prevents fluid loss and evaporation, meaning it remains closed for life and never requires manual top-ups with water.

Is this battery compatible with Start-Stop vehicles?

No. The Delkor Marine & Leisure range is specifically developed for marine craft and recreational vehicles. Vehicles equipped with smart automated idle start-stop systems require specialised Delkor EFB or AGM starting batteries to manage rapid cycling engine restart paths.

What are the benefits of the "MARINE" post configuration?

The dual marine post configuration incorporates standard tapered lead posts alongside threaded screw-down studs on each terminal block. This allows users to secure primary heavy starter cables to the tapered posts while cleanly fastening auxiliary system ring loops to the threaded studs via wing nuts.

How should I maintain this battery during the off-season?

Fully charge the battery before putting your vessel or caravan into seasonal storage. Because marine batteries can suffer from background draw and natural self-discharge, connecting a compatible multi-stage smart maintenance charger during the off-season is highly recommended to prolong plate life.
