MF86D SSB Marine Deep‑Cycle Battery – Heavy‑Duty Dual‑Purpose Marine & 4WD Power

The MF86D SSB Marine Deep‑Cycle Battery is one of the highest‑capacity dual‑purpose batteries in the SSB Marine Series, engineered for marine vessels, caravans, 4WD dual‑battery systems, camping setups, and heavy‑vehicle electrical systems that demand high cranking power, true deep‑cycle capability, and long‑term durability.

Delivering 850CCA, 130Ah, and 240 minutes of reserve capacity, the MF86D provides exceptional starting performance while powering onboard accessories for extended periods. It is built using extra thick plates, denser active material, and Cast Calcium‑Calcium Maintenance‑Free Technology, allowing it to deep‑cycle repeatedly without damaging its lifespan — something standard starting batteries cannot handle.

Factory‑filled, heat‑sealed, and maintenance‑free, the MF86D requires no water top‑ups, no corrosion checks, and no ongoing servicing. 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 MF86D provides reliable marine power with minimal maintenance.

📘 Product Description 

The MF86D SSB Deep‑Cycle Marine Battery is built using extra thick plates and denser active material, providing superior amp‑hour capacity and allowing deep‑cycling (discharging and recharging) without damaging the battery’s lifespan. This makes it ideal for marine vessels, caravans, 4WD setups, and heavy‑vehicle electrical systems that require long‑lasting accessory power.

Unlike standard starting batteries, the MF86D is engineered to handle repeated deep‑cycle use without performance loss. It is factory‑filled, heat‑sealed, and maintenance‑free — simply install and forget. No water top‑ups, no corrosion issues, and no ongoing servicing.

The MF86D is a Cast Calcium‑Calcium Maintenance‑Free Battery, designed using state‑of‑the‑art technology to deliver impressive cranking ability without sacrificing amp‑hour capacity. This makes it a true dual‑purpose battery, capable of powering accessories and starting engines with equal reliability.

Manufactured to ISO9001 International Quality Assurance Standards, the MF86D rivals almost any high‑performance deep‑cycle battery in Australia. It also features twin marine terminals and a charge indicator, making it easy to install and monitor.
