Battery Charger Upgrade

Well charged and maintained batteries on a boat this size are a necessity. In 1979, the Mainship company outfitted this boat with a Crown brand "Automatic Marine Converter". The boat also had 3-banks of batteries (main engine start, genset start, and house battery banks). So, out with the old and in with the new. Removal was fairly straightforward, but accessing one of the mounting fasteners was difficult due to existing access. Once removed, the remaing area provided ample space for the new charger. The ProSportHD 20 Plus Three Bank Battery charger was a much needed upgrade. The ProSportHD features a lightweight, tri-surface heatsink design. This delivers significantly faster charging through optimal cooling, while delivering true rated constant current charging amps during charge mode. Fully automatic multi-stage charging enhances battery performance while extending battery life.
  • ProMariner Digital Technology
  • Distributed-On-Demand™ Technology
  • Heavy Duty Tri-Surface Extruded Heat Sink Design
  • Expanded LED Display with Completion Status Gauge
  • Lightweight Design
  • Auto-Maintain Energy Saver Mode
  • Fully Automatic 5-Stage Digital Performance Charging
  • Built-in Quality and Safety
  • Easy Installation and Operation
In this particular installation, the charger needed to be installed upside-down so the leads would reach all three battery banks appropriately. With the new charger installed, I have much more confidence in the batteries and their ability to serve their purpose and fulfill the needs of the boat..
