Engineered with cutting-edge microprocessor technology and advanced software controls, this charger delivers reliable performance tailored specifically for the demanding marine environment.

Advanced Charging and Maintenance

The ProTechOne features all-digital, fully-automatic multi-stage charging technology, ensuring your batteries receive the optimal charge every time. The dedicated battery charging, sensing, and control system adapts to your battery's needs, providing precise conditioning and auto-maintaining capabilities. This multi-stage process maximizes battery performance and extends battery life, making it ideal for both short-term and long-term storage.

Durable and Weatherproof Design

Designed for the harsh conditions of marine applications, the ProTechOne boasts a gasket molded case that is waterproof and weatherproof, ensuring reliable operation even in extreme outdoor environments. The commercial-grade jacketed AC and DC cables provide maximum protection and durability, reducing the risk of cable damage and ensuring long-term performance on your vessel.

User-Friendly Battery Monitoring

Stay informed about your battery's status with the ProTechOne's push-to-test battery status monitor. The LED fuel gauge displays remaining battery power, while fault detection alerts you to issues such as poor battery connections, reverse polarity, or insufficient battery charge. An angled, easy-to-view LED dashboard provides instant visibility of AC power status, charge mode, and auto maintain (Energy Saver) mode. In the event of a fault, both the charging and auto maintain LEDs remain off, allowing for quick troubleshooting.

Energy Efficiency and Cost Savings

The Auto Maintain (Energy Saver) mode intelligently adjusts the charging output to keep your batteries fully charged while minimizing AC power consumption. This not only ensures your batteries are always ready for use but also helps reduce operating costs by lowering energy usage, making the ProTechOne a cost-effective solution for marine battery maintenance.
