The Amptech AT12900DS Deep Cycle Battery provides a high-performance, large-capacity power storage solution expertly engineered for the Australian recreational vehicle, 4WD, and leisure markets. Purpose-built to deliver low, steady energy discharge over extended periods, this heavy-duty 105 Ah battery is the ideal powerhouse for caravans, motorhomes, camper trailers, and off-grid setups. Incorporating advanced Valve Regulated Lead Acid (VRLA) tech and a starved electrolyte Absorbent Glass Mat (AGM) configuration, it offers exceptional strength, durability, and a massive capacity reserve to run intensive multi-day electrical accessories without breaking a sweat.

Perfect for drivers and campers who demand:

  • ✓ Enormous 105 Ah reserve capacity to sustain power-hungry 12V fridges, lighting grids, and auxiliary winches
  • ✓ Total indoor or cabin installation safety via a factory-sealed casing that prevents messy acid leaks or odours
  • ✓ Superior mechanical stamina built to resist structural plate shedding on corrugated regional tracks

Key Features & Benefits

Thicker Plate & Paste Tech

  • • High-density, thickened plate geometry guarantees reliable energy exchange over deep cycles
  • • Specialised deep-discharge paste formula combined with additives protects active material longevity
  • • Minimises the structural plate degradation that typically occurs during repetitive heavy cycling

Oxygen Recombination Armour

  • • Internal gas management loops actively recombine hydrogen and oxygen to eliminate water loss
  • • True "install and forget" design avoids any need for electrolyte fluid level top-ups
  • • Special grid alloys reduce internal outgassing and ensure a remarkably low self-discharge rate

Starved Electrolyte Design

  • • Liquid acid is fully absorbed in high-quality AGM separators to ensure a spill-proof build
  • • Advanced anti-vibration architecture effectively buffers internal plates from track shocks
  • • High-calibre glass mat layering isolates grids to prevent destructive micro short circuits

Reinforced Structural Safety

  • • Factory sealed with special compound epoxy alongside integrated pressure-controlled safety valves
  • • Heavy-duty ABS container housing significantly increases overall battery case tensile strength
  • • Robust T6-A terminal configuration provides a stable, low-resistance electrical connection point

Advantages & Considerations

Advantages

  • ✓ 1-year replacement warranty backing from an established local touring brand
  • ✓ Generous 105 Ah capacity delivers sustained off-grid power for long-distance touring
  • ✓ Non-spillable build operates reliably in almost any orientation profile
  • ✓ Excellent cyclic resilience when compared against standard general-purpose SLA options

Considerations

  • • Not engineered or safety-rated for primary engine cranking applications (No CCA rating)
  • • Complete upside-down operational installation layouts are not recommended by the manufacturer
  • • Substantial 30.60 kg mass requires a securely anchored mounting tray to limit kinetic movement

Frequently Asked Questions

What is the lifespan of this battery?

In dedicated cyclic configurations, this battery typically achieves several hundred deep discharge cycles. Total service lifespan depends heavily on average depth of discharge (DoD) percentages, regional operating temperatures, and proper charging methods.

Is this battery maintenance-free?

Yes, it is entirely maintenance-free. Thanks to sophisticated oxygen recombination technology, internal vapours are kept fully sealed and mixed inside the cells, completely avoiding any need for water top-ups or manual adjustments.

What applications is this battery compatible with?

This deep-cycle unit is optimised for caravan house systems, RV auxiliary trays, camper trailers, 12V portable fridge boxes, solar arrays, marine trolling motors, wheelchairs, mobility scooters, and emergency backup power loops.

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

Store the unit in a clean, dry, and cool environment sheltered away from direct sunlight. Bring it to a full 100% state of charge prior to storage; its high-purity alloy grids minimise self-discharge during extended idle periods.

What is covered under the warranty?

This battery is backed by a 1-year replacement warranty. This covers operational failures arising directly from internal manufacturing faults, construction oversights, or material defects under normal cyclic use.
