Why the Deka 24M5 Marine Master Rising to the Top?

• High Marine Cranking Power: Delivers 550 CCA and 675 MCA (Marine Cranking Amps) for dependable engine ignition in diverse nautical climates.
• Rugged Vibration Resistance: Fortified posts, straps, and computer-controlled welds protect internal components from the "wave-pounding" damage that kills standard automotive batteries.
• Dual-Terminal Convenience: Features Exclusive Molded-In Dual Terminals (Standard Post & Stainless Steel Stud) for easy, corrosion-resistant connections to both engine cables and accessory electronics.
• Maintenance-Free Flush Cover: The low-profile flush cover design eliminates acid leaks, keeps the battery top clean, and allows for easier installation in tight boat compartments.
• Extended Service Life: Utilizes Short-Protector Separators with a thicker backweb to prevent life-robbing electrical shorts and ensure consistent performance start after start.
