Dual Pro

Dual Pro, manufactured by Pro Charging Systems, is widely considered the safest and most reliable battery charging brand in the marine industry. Proudly made in the USA, Dual Pro chargers—including the Professional, Sportsman, and Recreation series—are fully waterproof, potted for vibration resistance, and engineered to extend the life of your batteries. Their advanced algorithms, such as the AutoProfile, are designed to detect and charge both AGM and Lithium batteries with 100% precision. At Freeport Marine Supply, we carry Dual Pro for boaters who want "bulletproof" electrical reliability and the peace of mind that their starting and trolling batteries will be ready to perform in any environment.
