Power-Sonic PDC-121050: 12V 105Ah AGM Deep Cycle Battery for Reliable Off-Grid Energy

Engineered for Sustained Cycling in Caravans, Marine, and Mobility Applications

The Power-Sonic 12V 105Ah AGM Deep Cycle Battery is purpose-built for applications demanding regular, deep discharges and consistent cycling. Unlike standard starter batteries, the PDC series features oversized negative plates and a specialised paste formulation that delivers true deep cycle performance, providing stable power over extended periods without compromising service life. This makes it an excellent choice for caravan solar systems, marine house banks, mobility scooters, and other off-grid setups where reliability is critical.

Utilising advanced Absorbent Glass Mat (AGM) technology, this battery offers superior performance, maintenance-free operation, and a spill-proof design that allows safe installation in any orientation. The valve-regulated construction ensures no acid leakage, reducing corrosion risks and making it suitable for enclosed spaces and transport. With a rugged ABS case (UL94-HB) and integrated carry handles, the PDC-121050 is built to withstand the vibrations and shocks common in mobile environments.

Key Features

• True deep cycle design with oversized negative plates and specialised paste for repeated deep discharges
• AGM technology for high efficiency, low self-discharge, and maintenance-free operation
• Spill-proof and valve-regulated construction allows flexible mounting in any position
• High energy density delivers 105Ah capacity in a compact footprint (306 x 168 x 208 mm)
• Rugged ABS case with impact resistance and integrated carry handles for easy transport
• Certified for air transport (D.O.T., I.A.T.A., F.A.A., C.A.B.) and U.L. recognised (MH 20845)
• M6 threaded terminals ensure secure, low-resistance connections for reliable power delivery

Why AGM Deep Cycle Technology Matters

AGM batteries use a fibreglass mat to absorb the electrolyte, immobilising it and enabling efficient gas recombination. This design not only prevents spills but also reduces internal resistance, allowing faster charging and higher discharge rates compared to flooded lead-acid batteries. The Power-Sonic PDC series enhances this with special additives in the paste that improve performance in deep discharge situations, a common challenge in off-grid and cycling applications. With an internal resistance of approximately 5.0 mΩ, this battery supports high surge currents, making it suitable for inverter loads and motor starts.

Applications

This battery is ideal for a wide range of deep cycle uses, including:

• Caravans and RVs: Powering lights, pumps, and appliances during extended trips
• Marine: Reliable house bank for trolling motors, electronics, and onboard systems
• Camping and 4WD: Running fridges, lighting, and charging devices off-grid
• Mobility Scooters and Electric Bikes: Providing consistent power for daily use
• Solar Energy Storage: Compatible with 12V solar setups for remote cabins and sheds

Built for Australian Conditions

With an operating temperature range of -20°C to 55°C during discharge and 0°C to 40°C during charge, the PDC-121050 is well-suited to Australia's diverse climates. The robust ABS case and vibration-resistant design ensure durability on corrugated roads and in marine environments. For optimal charging, pair with the Power-Sonic PSC-126000ACX charger to maximise battery life and performance.
