The SeaMaster marine battery range, leading in marine batteries, utilises Expanded Grid Technology (EXG) for superior marine cranking (MCA) and energy capacity (RC and AH), providing boating enthusiasts with the power they need in demanding marine applications and optimal vibration resistance in rough seas. EXG's unique construction involves super compressed rolled strips to create calcium plates with a dense grid pattern, resulting in a compact, heat and corrosion-resistant unit that delivers efficient cranking power. The shorter EXG plates have minimal gassing, reducing water loss and eliminating the need for acid top-ups. Compared to ordinary gravity-cast grids, EXG calcium grids are stronger, more compact, and offer superior current conductivity and cranking power, as reflected in the battery's exceptional specification ratings.

Features:

• SeaMaster Gold Sealed Expanded Calcium MF
• Reliable Performance
• Exceptional Vibration Resistance
• Improved Semi Cycling Ability, Higher Reserve Capacity
