Power-Sonic 12V 215Ah AGM Deep Cycle Battery: Reliable Energy for Demanding Off-Grid Applications

Engineered for Sustained Deep Cycling in Caravans, Marine, and Remote Power Systems

The Power-Sonic 12V 215Ah AGM Deep Cycle Battery is purpose-built for applications requiring consistent, long-duration energy delivery. Featuring oversized negative plates and a specialised paste formulation, this battery delivers true deep cycle performance, providing stable power over extended periods without compromising service life. Its Absorbent Glass Mat (AGM) technology ensures maintenance-free operation, superior vibration resistance, and reliable performance in demanding Australian conditions.

With a 20-hour capacity of 215Ah, this battery is an ideal choice for caravan solar systems, marine house banks, mobility scooters, and off-grid energy storage. The valve-regulated, spill-proof design allows safe installation in any orientation, making it suitable for confined or mobile spaces where conventional flooded batteries would pose a risk.

Advanced AGM Construction for Deep Cycle Reliability

Unlike standard batteries that degrade quickly under repeated deep discharges, the Power-Sonic PDC series is engineered for cyclic endurance. The oversized negative plates and specialised paste additives enhance recovery from deep discharge events, a common challenge in off-grid and mobile applications. This design reduces the risk of premature capacity loss, ensuring dependable performance over hundreds of cycles.

The AGM separator immobilises the electrolyte, eliminating acid stratification and enabling efficient gas recombination. This results in a maintenance-free, sealed battery that does not require watering and can be operated in any position without leakage. The low internal resistance (approx. 3.0 mΩ) supports efficient charge acceptance and high discharge currents, making it suitable for both cyclic and standby applications.

Key Features

• 215Ah capacity (20-hr rate) for extended runtime in off-grid and mobile setups
• Oversized negative plates and specialised paste for true deep cycle performance
• AGM technology ensures maintenance-free, spill-proof operation in any orientation
• Low internal resistance for efficient charging and high surge current capability
• Rugged ABS case (UL94-HB) with impact resistance for harsh environments
• Certified for air transport (D.O.T., I.A.T.A., F.A.A., C.A.B.) and U.L. recognised
• Integrated rope handles for safe lifting and positioning (weight: 62.2 kg)

Built for Australian Conditions

The impact-resistant ABS case and robust internal construction withstand vibration, shock, and temperature extremes typical of Australian off-road and marine environments. The battery operates reliably in discharge temperatures from -20°C to 55°C, ensuring consistent performance in cold mornings or hot afternoons. The protective terminal caps prevent accidental short circuits during transport and installation, adding an extra layer of safety.

With M8 threaded terminals, this battery accommodates standard ring lugs for secure, low-resistance connections. The ergonomic rope handles facilitate handling despite the substantial weight, reducing the risk of injury during installation in tight compartments.

Versatile Applications

This battery is well suited to a range of demanding applications:

• Caravans and RVs: Powers lights, fridges, and inverters for extended off-grid stays
• Marine: Ideal for house banks on boats, withstanding vibration and occasional tilting
• Mobility Scooters and Electric Bikes: Delivers deep cycle endurance for daily use
• Off-Grid Solar Systems: Stores energy from solar panels for remote cabins or sheds
• Camping and 4WD: Provides reliable power for portable fridges and accessories

Optimised Charging for Long Life

For cyclic applications, charge at a constant voltage of 14.1 to 14.7V at 20°C. For standby or float service, maintain 13.5 to 13.8V. Using a quality charger like the Power-Sonic PSC-1212000ACX ensures proper charge profiles and maximises battery life. Avoid discharging below 50% depth of discharge to extend cycle life.
