Sterling ProCharge Ultra Battery Charger 12 volt / 40 Amp

Model PCU1240, 3 banks -Identical to ProMariner ProNautic 1240P

Availability: In stock

Product Description


    The Sterling ProCharge Ultra 1240 all-digital marine 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 footprint and is lightweight. It has 11 pre-programmed 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.

    We recommend this 40 amp charger for boats with 150 to 330 amp-hour battery banks. 

    That the Sterling ProCharge Ultra resembles the ProMariner ProNautic is no accident - they were co-engineered and are jointly manufactured - the labels are the only difference. Until recently, the ProMariner chargers were sold in the North American market and the Sterling ones were sold in Europe and the UK. Sterling has recently begun marketing in the U.S., and offers full support and a 5-year warrany from their operations center in Maine.

    The Sterling ProCharge Ultra was awarded Sail Magazine's 2011 Pittman Innovation Award in the Systems Category. It is one of the most advanced boat battery chargers on the market.
