SMART Nauticharger

Stage Battery Charger.
The "Smart Charger" series is designed for professional usage. With temperature compensation design (25A/40A model only), it can assure 100% charge of your battery in any circumstance and at any temperature. With selectable max charging time limitation for the bulk and absorption stage (4-8-12hours), this charger is suitable for charging both traditional and gel batteries. (please refer at user manual of your battery).
Smart Charger offering 2 or 3 outputs to charge 2 or 3 battery banks simultaneously. It uses a constant current charge as main stage, while monitoring the battery voltage. When this reaches a pre-set cut off point, it switches to an intermediate constant voltage 'float charge'. Only when the battery is detected properly charged, Smart Charger will switch to the final stage for correct long-term battery maintenance. If at any time it detects that the battery has been discharged, it will automatically revert to the constant current stage.
