The D31 Deltec Deep Cycle Dual Purpose Battery stands as the heavy-duty powerhouse of the recreational range, specifically optimised for high-end leisure vehicles, caravans, and marine vessels. Expertly engineered to balance a massive 800 CCA engine cranking surge with a substantial 100 Ah deep cycling reserve, it serves as the ultimate compromise for systems requiring reliable starting mixed with sustained accessory power. Manufactured using high-grade components, this factory-sealed maintenance-free unit provides the electrical stability needed to conquer demanding off-road corrugations and unpredictable open-water environments across Australia and New Zealand.

Perfect for drivers who demand:

  • ✓ A high-capacity dual-purpose build capable of cranking large 4WD or marine engines while backing up house loads
  • ✓ Superior cyclic stamina to power advanced electronic devices, portable fridges, and lighting configurations
  • ✓ A ruggedised, spill-proof architecture that eliminates ongoing maintenance or fluid level top-ups

Key Features & Benefits

Patented X-Frame Technology

  • • Full-framed stamped grid configuration provides ultra-stable and rapid electrical paths
  • • Delivers reliable starting performance to ignite high-displacement engines when it counts
  • • Limits internal grid growth and structural decay to effectively minimise early field failures

High Durability Plate Technology

  • • Specialised micro-fibre binding material reinforces the durability of the internal active mass
  • • Engineered for exceptional performance and longevity in demanding c20 cyclic applications
  • • Suppresses premature plate shedding to provide a prolonged power supply for leisure devices

Advanced Calcium+ Chemistry

  • • Highly pure lead-calcium-tin alloy shields internal components against grid corrosion
  • • Drastically reduces natural self-discharge while the vehicle or vessel sits idle between trips
  • • Restricts internal gas venting to successfully prevent electrolyte and fluid loss

Recreational Vibration Armour

  • • Built tough to survive corrugated outback tracks, off-road touring, and harsh marine hull slap
  • • Seamlessly bridges the gap between raw starting power and deep-cycling accessory support
  • • Designed to match or exceed the requirements of modern, accessory-heavy touring setups

Advantages & Considerations

Advantages

  • ✓ Massive 800 CCA output handles large 4WD diesel engines and marine configurations
  • ✓ Full 100 Ah deep cyclic capacity delivers consistent power for moderate energy setups
  • ✓ Maintenance-free architecture eliminates messy acid monitoring or manual top-ups
  • ✓ Micro-fibre plate reinforcement guarantees a highly prolonged operational service life

Considerations

  • • Substantial Group 31 footprint length (330 mm) requires ample battery box or tray space
  • • Heavy-duty physical mass requires careful manual handling during physical swap-overs
  • • Dual-purpose configuration is not compatible with passenger vehicles utilising Stop-Start systems

Frequently Asked Questions

What is the lifespan of this battery?

In typical marine, 4WD, and leisure applications, this premium battery delivers a reliable service life of 3 to 5 years. Total longevity depends heavily on the average depth of discharge per trip, charging system efficiency, and local storage temperatures.

Is this battery maintenance-free?

Yes, this battery features a completely Sealed Maintenance-Free (SMF) architecture. The advanced Calcium+ lead-calcium-tin alloy prevents internal fluid loss and gas vapour evaporation, meaning you never need to check cell levels or add distilled water.

What vehicles/applications is this battery compatible with?

The Deltec D31 is designed for multi-role applications. It is the primary choice for caravan battery compartments, motorhomes, marine dual-battery configurations, and 4WD vehicles that utilise a large Group 31 size tray footprint.

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

Store the unit in a cool, clean, and dry storage centre away from seasonal weather elements. Ensure it is fully charged before taking it offline, and connect it to an automotive smart charger periodically over long periods to counter natural self-discharge and preserve cell health.

What is covered under the warranty?

This dual-purpose battery includes a dedicated consumer recreational warranty. This covers sudden operational failures resulting from factory material anomalies or structural assembly defects under normal leisure, marine, or cyclic use.
