The D27 Deltec Deep Cycle Dual Purpose Battery is an elite, high-performance power unit built as the primary choice for premium leisure, marine, and RV applications. Explicitly engineered to offer the perfect compromise between robust engine cranking power and extensive deep-cycle reserves, this sealed maintenance-free battery handles the high energy demands of modern accessories with ease. Produced in a state-of-the-art facility, it features reinforced internal architectures to reliably withstand the punishing off-road corrugations and open-water pounding of the Australian climate.

Perfect for drivers who demand:

  • ✓ A high-capacity dual-purpose battery capable of crisp engine ignition and deep accessory cycling
  • ✓ Consistent, prolonged power for heavily equipped caravans, camper trailers, 4WDs, and marine vessels
  • ✓ A premium maintenance-free design that eliminates liquid top-ups during long regional adventures

Key Features & Benefits

Patented X-Frame Technology

  • • Full-framed stamped grid architecture provides stable and highly efficient electrical pathways
  • • Delivers powerful, reliable starting current to safely fire up main engines in all conditions
  • • Protects internal grids from growth and material decay to secure a prolonged service life

High Durability Plate Technology

  • • Advanced micro-fibre binding additives increase the ruggedness and density of the active mass
  • • Optimised for exceptional performance in deep c20 cyclic discharge applications
  • • Supplies stable and prolonged electrical output to keep multi-device loads running smoothly

Calcium+ Advanced Alloy

  • • Highly pure lead-calcium-tin alloy technology provides superior prevention against grid corrosion
  • • Minimises natural self-discharge to preserve cell health when your vehicle is stored between seasons
  • • Eliminates internal electrolyte fluid loss for a true maintenance-free operational experience

Recreational Dual Armour

  • • Built tough to handle corrugated outback roads, heavy off-road driving, and rough marine hull slap
  • • Seamlessly balances high initial cranking power with an expanded 90-minute reserve capacity
  • • Meets or exceeds original equipment specifications for advanced, electronics-heavy modern fleets

Advantages & Considerations

Advantages

  • ✓ Strong 750 CCA output effortlessly starts modern marine and large 4WD engines
  • ✓ Generous 90 Ah rating provides substantial power for moderate cyclic house loads
  • ✓ Sealed maintenance-free configuration successfully prevents messy acid leaks
  • ✓ Patented X-Frame grid technology directly minimises the risk of early internal failure

Considerations

  • • Expanded Group 27 footprint length (302 mm) requires verification against standard trays
  • • Heavy-duty design requires proper physical handling or lifting tools when swapping over
  • • Not intended for use in specialised passenger vehicles featuring automatic Idle Stop-Start systems

Frequently Asked Questions

What is the lifespan of this battery?

Under normal leisure, RV, and marine operational routines, this battery typically provides a service life of 3 to 5 years. Total longevity depends heavily on cyclic depth of discharge, alternator charging parameters, and average local storage temperatures.

Is this battery maintenance-free?

Yes, this battery features a completely Sealed Maintenance-Free (SMF) design. The advanced Calcium+ alloy chemistry limits vapour evaporation, ensuring you never have to check fluid depths or complete water top-ups.

What vehicles/applications is this battery compatible with?

The Deltec D27 is optimised for dual-purpose roles. It serves as the primary choice for 4WD dual-battery boxes, mobile caravans, motorhomes, and marine vessels requiring a single dependable power source for starting and electronic accessories within a Group 27 size constraint.

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

Store the unit in a cool, clean, and dry storage area away from harsh outdoor elements. Bring it to full charge prior to storage, and utilise a multi-stage smart charger periodically over long periods to counter natural self-discharge and safeguard voltage health.

What is covered under the warranty?

This product comes backed by a dedicated recreational warranty. It covers unexpected operational failures resulting directly from manufacturing assembly defects or material faults under standard leisure or c20 cyclic operating conditions.
