The Fullriver DC120-12B Deep Cycle AGM Battery is the ultimate premium power solution for heavy-duty cycling applications across Australia. Engineered to the highest industrial standardised profiles, this sealed Absorbed Glass Mat (AGM) battery delivers a true deep-cycle service life without the hazardous maintenance requirements of traditional flooded alternatives. Utilising significantly more lead, extra-heavy full-frame plates, and a proprietary high-density active paste, it provides reliable, sustained capacity and exceptional reserve power over hundreds of deep discharge and recharge cycles.

Perfect for drivers who demand:

  • ✓ Uncompromised auxiliary power for off-grid RV setups, caravans, and marine installations
  • ✓ Clean, non-hazardous operation for indoor medical mobility and commercial floor machines
  • ✓ Maximum cycle-life and ultra-reliable storage for remote solar and renewable energy systems

Key Features & Benefits

Platelock™ Vibration Armour

  • • Extra-thick, full-frame internal plates secure vital active mass against mechanical shock
  • • High-purity lead-calcium-alloy grids minimise internal resistance and degradation
  • • Built tough to handle structural stress on heavily corrugated regional tracks and tough job sites

Sealed Maintenance-Free Cover

  • • Electrolyte is completely absorbed in sponge-like glass-mat separators to prevent any spillage
  • • True "install and forget" design avoids corrosive acid leaks and zero fluid top-ups
  • • Non-hazardous classification allows safe mounting inside vehicle cabins and sensitive workspaces

Advanced Safety Systems

  • • Self-regulating pressure relief valves prevent dangerous internal gas build-ups
  • • Completely sealed architecture routes out atmospheric moisture and ignition risks
  • • Rugged shock-absorbing casing eliminates the danger of external acid vapour damage

Electrical Stability

  • • High-density active paste formula optimises discharge runtime and sustained capacity
  • • Unique low-resistance microporous separators ensure significantly faster recharge acceptance
  • • Ultra-low self-discharge rate of just 2% per month at 20°C ensures long-term storage health

Advantages & Considerations

Advantages

  • ✓ Industry-leading 24-month warranty coverage for guaranteed peace of mind
  • ✓ Massive 120 Ah capacity delivers sustained off-grid power
  • ✓ Robust M8 threaded terminal posts ensure low-resistance wiring connections
  • ✓ Highly porous AGM separators allow superior high-current flow

Considerations

  • • Heavy 36.50 kg build requires sturdy structural mounting trays and careful lifting
  • • Designed purely for deep cycle discharge; not intended for under-bonnet engine starting
  • • Always verify physical battery space footprint dimensions to confirm adequate installation clearance

Frequently Asked Questions

What is the lifespan of this battery?

The operational lifespan of the Fullriver DC120-12B depends on depth of discharge and temperature management, but it is engineered to be discharged and recharged hundreds of times. With its high-density paste and heavy-duty frame design, users typically achieve an exceptionally long and reliable service life, far exceeding that of standard AGM variants.

Is this battery maintenance-free?

Yes, this battery is completely Sealed Maintenance-Free (SMF) and classified as non-hazardous. The internal acid is fully absorbed in glass-mat separators, meaning it will never leak, require fluid top-ups, or require regular hydrometer maintenance checks.

What vehicles/applications is this battery compatible with?

This deep-cycle battery is highly optimised for cyclic applications rather than vehicle engine starting. It is the preferred option for off-grid renewable energy storage, caravans, motorhomes, marine house power supplies, golf carts, aerial work platforms, and medical mobility equipment.

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

Store the battery in a cool, dry location, out of direct exposure to extreme temperatures. Thanks to an incredibly low self-discharge rate of just 2% per month at 20°C, it remains stable for long periods. As a best practice, fully charge the unit before storing it and top it up with a compatible smart charger every few months.

What is covered under the warranty?

This premium battery includes a comprehensive 24-month local warranty. It covers structural and material failures caused by assembly faults during regular cyclic operations, ensuring full protection of your investment.
