Houseboaters find the ProCharge Ultra from Sterling-Power-USA to be a big hit due to its efficiency, ability to run on 90vac to 270vac (even a surging generator) and especially because it allows the boat owner that stays hooked up to shore power frequently to not overcharge and over cycle the batteries, because the ProCharge Ultra allows for shore power bypass, while keeping the batteries at float voltages.
The new line of Marine Grade, Power Factor Corrected Battery Chargers set a new standard of what you should expect from your battery charger when it comes to features, performance and price. Years of experience in the battery charging industry has provided the insight to include everything they could possibly think of and combine it all into the ProCharge Ultra line of feature rich, high performance marine grade battery chargers. This exceptionally efficient power factor corrected battery charger runs on any Global AC Power source between 90-260 volts, requires less input power, produces less waste heat, and still has a remarkably small, lightweight footprint. Did we mention 11 pre-programmed battery charging curves as well as one user customizable battery profile? Check the real time voltage or current output on the digital display or on the optional remote control that can be either surface, recess, or flush mounted over 30 feet away from the battery charger.
