(20A model only) - single pole/single throw switch required. (sold separately) • Battery temperature compensation prolongs battery life (temperature sensor 1820 included) • Start isolation protects sensitive electronics from voltage sags and spikes • Includes LED remote indicator for charge status at the helm • Snap-on insulating cover Nominal Output Voltage 12V DC Output Connections 2 positive, 1 negative Universal AC Input 100V-240V AC, 50/60 Hz Typical Float Voltage (25°C) 13.5V DC Typical Absorption Voltage (25°C) 14.4V DC ACR Combine Voltage 13.0V ACR Open Voltage 12.75V Terminal Stud Size 1/4"-20 (accepts M6 ring terminal) Maximum 1/4" Terminal Stud Torque 60 in-lb (6.8 Nm) Positive Terminal Stud Size (20A model only) 3/8"-16 (accepts M10 ring terminal) Maximum 3/8" Terminal Stud Torque 140 in-lb (15.8 Nm) Quick Connect Terminal Size 1/4" x 0.032" Warranty 5 Year Battery Types Flooded, AGM, TPPL PN Total Output Current ACR Continuous Plug Style 7605 10A 65A North American: NEMA 5-15P 7608 20A 170A North American: NEMA 5-15P 5 YEAR WARRANTY AC & DC Battery Charging Explained DC Charging (Away from the Dock or Garage) The BatteryLink Charger incorporates DC charging through an integrated Automatic Charging Relay (ACR). An ACR uses a relay combined with a voltage sensing circuit. When a DC charge is applied to the start battery, and causes the voltage to rise above 13.0V, the relay closes and combines the two batteries to share the charge. When the charge is taken away or a load on the battery causes the voltage to drop below 12.75V, the relay will open, isolating the two batteries. This means that even when the BatteryLink Charger is disconnected from AC power you can charge both your battery banks with a DC charging source, like an engine alternator. AC Charging (At the Dock or Garage) The BatteryLink Charger is powered by AC when the cord is plugged in, and will source current to charge your batteries. However, unlike a typical two bank charger, the BatteryLink Charger will charge both batteries simultaneously using the integrated ACR. This works in the same way as when an external DC charging source is used. When AC power is applied, and the voltage of the start battery rises above 13.0V, the ACR will close. This combines the batteries, allowing charge current to flow to the auxiliary battery as well as the start battery. For this reason, the BatteryLink Charger can only be used in 12V applications.
