MF70D SSB Marine Deep‑Cycle Battery – Genuine Dual‑Purpose Marine & 4WD Power

The MF70D SSB Marine Deep‑Cycle Battery is engineered for marine users, 4WD enthusiasts, and heavy‑vehicle operators who need strong cranking power, true deep‑cycle capability, and long‑term durability in harsh environments. Delivering 600CCA, 85Ah, and 200 minutes of reserve capacity, the MF70D is a genuine dual‑purpose battery — capable of starting engines AND powering onboard accessories for extended periods.

Unlike standard starting batteries, the MF70D uses extra thick plates, denser active material, and Cast Calcium‑Calcium Maintenance‑Free Technology, allowing it to deep‑cycle repeatedly without damaging its lifespan. This makes it ideal for boats, caravans, 4WD dual‑battery systems, camping setups, and marine electrical systems that demand both starting strength and accessory endurance.

The MF70D is factory‑filled, heat‑sealed, and maintenance‑free. No topping up, no water checks, and no corrosion issues. Its rugged construction is designed to withstand vibration, pounding seas, moisture, and temperature extremes. With twin marine terminals and a built‑in charge indicator, the MF70D provides reliable marine power with minimal maintenance.

Warranty

The MF70D includes a Marine Warranty (refer to manufacturer warranty guide).
