The DEL-31S Deltec Commercial and Automotive Battery is a heavy-duty powerhouse engineered to deliver uncompromised performance when it counts. Featuring threaded stud terminals common in commercial fleets, this battery is purpose-built to meet the rigorous demands of construction machinery, heavy goods vehicles, and high-demand passenger applications. Built in a state-of-the-art facility using patented X-Frame technology, it supplies an outstanding 900 CCA of cranking power and a 180-minute reserve capacity to handle ongoing cabin house loads and prevent early failure in the harshest Australian environments.

Perfect for drivers who demand:

  • ✓ Proven starting capabilities for demanding commercial vehicles and heavy transport haulage
  • ✓ A high reserve capacity to sustain consistent results when cabin house loads are present
  • ✓ A premium, zero-maintenance replacement designed to withstand local driving conditions

Key Features & Benefits

Patented X-Frame Technology

  • • Full-framed stamped grid technology optimises current flow for stable starting performance
  • • Minimises structural grid growth to protect against internal short circuits
  • • Provides reliable, heavy-duty engine cranking all the way through your journey

High Durability Plate Armour

  • • Advanced micro-fibre formulation increases the absolute durability of the active mass
  • • Protects vital components against relentless vibration shocks on and off the road
  • • Supplies a prolonged, highly stable power supply while reducing the risk of premature failure

Calcium+ Alloy Formulation

  • • Ultra-pure lead-calcium-tin alloy provides superior prevention against grid corrosion
  • • Drastically curtails natural self-discharge when fleet machinery sits idle
  • • Guards against premature electrolyte loss under high under-bonnet operating temperatures

Sealed Maintenance-Free Cover

  • • Fully sealed factory architecture permanently isolates internal electrolyte fluids
  • • Complete "install and forget" design eliminates routine maintenance and top-up schedules
  • • Spill-proof casing structure ensures your engine bay remains completely safe and protected

Advantages & Considerations

Advantages

  • ✓ Massive 900 CCA output turns over heavy commercial diesel machinery with ease
  • ✓ High 180-minute Reserve Capacity provides consistent support for electrical cabin loads
  • ✓ Dual-purpose commercial build provides reliable performance on and off-road
  • ✓ Maintenance-free configuration removes routine distilled water inspection tasks

Considerations

  • • Total height including studs reaches 242 mm; check clear under-bonnet room
  • • Features threaded stud terminals; ensure your vehicle's lead connections match this layout
  • • Not engineered to meet the deep cyclic requirements of modern passenger Idle Stop-Start systems

Frequently Asked Questions

What is the lifespan of this battery?

In rugged commercial and standard transport environments, this battery is designed to deliver an extended service life of 3 to 5 years. Total lifecycle depends on vehicle charging systems, fleet duty cycles, and regional climate variations.

Is this battery maintenance-free?

Yes, this model features a true Sealed Maintenance-Free (SMF) build. The combination of advanced calcium alloy and X-Frame technology prevents internal liquid loss, ensuring you never need to check fluid depth or top up water cells.

What vehicles/applications is this battery compatible with?

This battery is an ideal replacement choice for heavy goods vehicles, construction machinery, agricultural equipment, and large passenger vehicles, accepting a standard Group 31 casing footprint with stud-style terminal layouts.

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

Store the unit in a cool, dry area out of direct contact with weather extremes. Ensure the cells are fully charged before storing, and attach a compatible electronic smart charger periodically over long idle periods to preserve voltage health.

What is covered under the warranty?

This product includes full warranty coverage. It protects against operational failures caused directly by internal material defects or assembly errors under regular operation, subject to standard terms and commercial conditions.
