ProCharge Ultra-
The Ultimate Battery Charger


Our classic 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 & price. Years of experience in the battery charging industry has provided us the insight to include everything we 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 Eleven 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.
