ProTechOne - 4 AMP - Corded

ProMariner's ProTechOne Fully Automatic Onboard Battery Charger and Maintainer utilizes the latest in microprocessor and software control charging and energy-saving auto maintain technology. Safe for short and long-term storage with multi-stage charging, conditioning, and auto maintaining proved to maximize battery performance and life. Designed for weatherproof applications and years of trouble-free use, ProTechOne boasts a gasket molded case design for outdoor use with commercial-grade jacketed AC and DC cables for maximum cable protection and durability. 

ProTechOne incorporates a push-to-test battery status monitor showing remaining battery power, in addition to fault detection of battery connections, reverse polarity, or battery too low to charge. In the event of a fault, both the Charging and Auto maintain LEDs will remain off. An angled easy-to-view LED dashboard provides the quick status of AC Power, Charge Mode, and Auto Maintain (Energy Saver) mode, which controls the charging output as needed to maintain a fully charged battery, lowering AC consumption and reducing operating cost.

Features:

  • All-digital charging technology with fully-automatic multi-stage digital charging
  • Dedicated battery charging, sensing, and control
  • Push-to-test battery monitor LED fuel gauge status
  • Waterproof DC safety fuse for maximum DC wire protection
  • Ignition protected and FCC Class A for quiet operation and non-radio interference
