Review: Great charger - So far this appears to be working great, charging and maintaining my boat batteries Easy to use with clear directions, easy to install Review: Great Product - I had the original version of this charger in our Crownline for 8 years and loved it. It worked perfectly, and kept the original batteries that came with the boat working great for that entire time. That is, until it got struck by lightning... So I ordered this, updated version of the same charger. It is exactly as nice as the old one with some nice upgrades including the charging gauge and the easier method of selecting the battery chemistry. I was extremely happy with the first one and would still have it if not for our mishap. I expect this one will carry on as the old one did, keeping my original batteries topped up when the boat is sitting. ## Features - ProSport HD 12A Dual Bank Waterproof Marine Battery Charger (Part Number 44012) replaces the old ProMariner Gen 3 ProSport 12 (part number 43012) - ProMar Digital Technology: Microprocessor and software controlled charging technology for fast, precise charging - Distributed-On-Demand Technology: 100% of all available charging amps are utilized by distributing unused charging amps to any one or combination of all batteries as needed - Heavy Duty Tri-Surface Extruded Heat Sink Design: Upper, lower and rear facing heat sink design for optimal cooling while delivering true rated constant current charging amps during its two charge mode - Expanded LED Display with Completion Status Gauge: LED fuel gauge style completion status.
