MK Deka 27M6 12VDC Flooded Lead-Acid Battery

MK Deka 27M6 Marine Master: 12V 1050 MCA Group 27 Starting Battery

The MK Deka 27M6 is a premium 12V marine starting battery engineered for high-horsepower outboard engines and demanding marine environments. As part of the Marine Master® series, it is designed to provide massive "turn-key" cranking power for professional captains and serious offshore anglers.

Key Benefits

• Superior Cranking Power: 1050 MCA and 840 CCA ensure reliable starts for large-displacement engines, even in cold-start conditions.
• Heavy-Duty Construction: Features Power-Perform™ Full-Frame Plates and anchor-bonded elements to survive the severe vibration and "wave-pounding" typical of offshore boating.
• Marine-Specific Terminals: Equipped with molded-in Dual Terminals (Standard Post + Stainless Steel Stud) for easy, corrosion-resistant wiring of engine leads and electronics.
• Low-Maintenance Design: A manifold-vented flush cover reduces electrolyte loss and prevents acid leakage while allowing for easy inspection in high-heat environments.
• Eco-Friendly & American Made: 98% recycled material content and manufactured in East Penn’s world-class Pennsylvania facility.
