Product Description

Advanced Electronic, Fully Automatic Three-Step Marine Battery Charger

  • Distributed, On-Demand Charging: Automatically senses and distributes a full 10, 15 or 30 amps (model specific) to any one bank or combination of all banks.
  • Faster Charging: Two to three times faster than traditional battery chargers with true three-step charging technology. Each step is electronically controlled for the fastest charge.
  • Professional Performance: 100% battery charge guaranteed. 100% charging output with AC power as low as 90 VAC while using long extension cords at the dock, lodging site or home. Proven to condition and extend the life of your batteries.
  • Compact Lightweight Design: Rugged space-saver all-aluminum housing is half the height of leading traditional chargers. Unit is not potted and is completely serviceable for lifetime of use under ProMariner’s lifetime repair guarantee.
  • Easy Operation: Pre-wired for easy installation. Onboard push-to-test charge level and mode indicators. Internal battery selection—lead acid, gel or AGM compatible.

True Three-Step Charging Electronically Controlled for the Fastest Charge

  • Step 1: Fast Charge: Charger delivers maximum amperage to batteries for the fastest charge (current regulation mode) until battery voltage is raised to 14.6 VDC.
  • Step 2: Absorption Charge: Maximizes charge and holds voltage at 14.6 VDC for three hours (voltage regulation mode) reducing sulfate buildup and conditions batteries.
  • Step 3: Float Mode: A precision 13.3 VDC finishing voltage that maintains your batteries (step-down voltage regulation mode), which is perfect for short or long storage periods and will never overcharge your batteries.

Faster Charging 100% Charge Guaranteed

  • ProMariner’s advanced electronic technology will deliver 2 times the amps to your batteries in the same amount of time when compared to leading traditional linear chargers. That means the ProTournament will charge your batteries twice as fast.
  • ProTournament’s Distributed On-Demand Charging will automatically distribute its full-rated output of 10, 15 or 30 amps (model specific) to any one bank or combination of all battery banks. ProTournament distributes and uses every charging amp with no waste unlike other two- and three-bank chargers with an amp limit per bank.
