The Fullriver DC20-12 Deep Cycle AGM Battery is a premium, ultra-compact power storage cell engineered to deliver heavy-duty cycling capabilities in demanding Australian applications. Moving well beyond standard automotive starting variants, this compact power source utilises more lead mass, extra-heavy full-frame plates, and a proprietary high-density active paste. This advanced construction ensures it delivers sustained reserve power and maintains electrical capacity through hundreds of deep-discharge cycles, offering the long life of a true deep-cycle battery with a completely maintenance-free, non-hazardous profile.
Perfect for drivers and operators who demand:
- ✓ A space-saving auxiliary power source for highly compact RV setups, portable electronics, and small camper trailers
- ✓ Total indoor safety and non-spillable cleanliness for medical mobility scooters, golf, and utility applications
- ✓ A low-maintenance, vibration-resistant battery bank for small solar systems and reliable backup power supplies
Key Features & Benefits
Platelock™ Vibration Armour
- • Extra-thick, full-frame internal plates securely lock active materials against mechanical shock
- • High-purity lead-calcium-alloy grids drastically minimise internal degradation and grid growth
- • Built tough to survive continuous movement on regional roads and demanding commercial worksites
Sealed Maintenance-Free Cover
- • Acid electrolyte is completely absorbed within highly porous microporous glass-mat separators
- • The recombination closed-loop system entirely avoids premature fluid evaporation and terminal corrosion
- • True "install and forget" architecture removes any need for manual distilled water top-ups
Electrical Stability & Efficiency
- • Proprietary high-density active paste formula optimises discharge runtime and sustained capacity
- • Unique low-resistance separator design ensures significantly quicker and more efficient recharge acceptance
- • Low self-discharge rate of just 2% per month at 20°C guarantees exceptional seasonal storage health
Advanced Safety Systems
- • Self-regulating pressure relief valves safely manage internal pressure variances during fast recharges
- • Certified non-hazardous construction permits flexible orientation and indoor placement without risks
- • Shock-absorbing outer casing safely seals internal components away from external ignition risks
Advantages & Considerations
Advantages
- ✓ 12-month warranty coverage for guaranteed consumer peace of mind
- ✓ Ultra-lightweight 6.44 kg structural layout allows for simplified installation
- ✓ Non-hazardous, clean, and gas-free operation allows for placement in medical mobility setups
- ✓ Highly porous AGM separators allow superior high-current electrical flow parameters
Considerations
- • Compact 20 Ah capacity is engineered for light cyclic loads, not heavy industrial demands
- • Dedicated deep-cycle build profile; not intended for standard under-bonnet automotive engine starting
- • Not engineered to match the rapid start demands of modern automotive Idle Stop-Start systems
Frequently Asked Questions
What is the lifespan of this battery?
Fullriver deep-cycle AGM batteries are built to withstand deep discharges and withstand hundreds of recharges. With standard cyclic routines, accurate multi-stage charging, and careful management of discharge depths, this ultra-reliable battery delivers an exceptionally long, stable service life compared to generic options.
Is this battery maintenance-free?
Yes, this model features a completely Sealed Maintenance-Free (SMF) architecture. Because the liquid electrolyte acid is fully absorbed in sponge-like absorbent glass mats between the plates, there is zero risk of spillage, and you will never need to top up fluid levels.
What vehicles/applications is this battery compatible with?
This battery is a dedicated power-supply choice optimised for cyclic deployment rather than for automotive engine starting. It is the preferred choice for small caravan or RV setups, renewable solar systems, medical mobility equipment, utility carts, aerial work platforms, and small floor machines.
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. Due to its exceptionally low self-discharge rate of 2% per month at 20°C, it remains stable over extended standby intervals. Always charge the unit fully before storing, and periodically refresh it with a compatible smart charger.
What is covered under the warranty?
The local 12-month warranty covers early operational or structural failures caused directly by internal manufacturing errors or material defaults. It ensures secure consumer protection when the product is used in its intended deep-cycle or power supply applications under regular conditions.
