Description
P65 Warning
Additional information
Charge two batteries at or away from the dock with a 10A multistage battery charger and integrated 65A Automatic Charging Relay (ACR). This unit shows a level of sophistication normally only found on larger and more expensive chargers. The charger comes with a remote display and a temperature sensor, a fully automatic Three Stage Charger, and an Automatic Battery Combiner
AC charging at the dock: Use AC shore power to charge two isolated battery banks with the 3 Stage 10 Amp battery charger
DC charging away from the dock: Share the DC power from the alternator with both the Start and the Auxiliary battery through the integrated 65A ACR
Battery Temperature Compensation prolongs battery life
Start isolation protects sensitive electronics from voltage sags and spikes
Includes LED remote indicator for charge status at the helm
Snap-on insulating cover
One-piece stainless flange nuts ensure safe and secure connections
Ignition protected to SAE J1171 means it is safe for use with gasoline engines
Water resistance to IP67 means it is protected against the effects of immersion in water for a limited period
Dimensions 6.66" x 4.36" x 2.13"
For AGM or Flooded Batteries

BATTERYLINK® CHARGER OVERVIEW
The BatteryLink® Charger is a 120VAC nominal input, 12VDC nominal output, 10A battery charger with integral battery combiner (ACR) providing a second battery connection, as well as standard ACR function when AC power is not present.
AC plug-in at the dock, provides 10 Amps of charge current
Integrated ACR automatically combines batteries during charging, isolates batteries when discharging and when starting engines
Start isolation protects sensitive electronics from voltage sags and spikes
Battery temperature compensation prolongs battery life
Supports alternators up to 65 Amps
One-piece stainless flange nuts ensure safe and secure connections
Ignition protected?safe for installation aboard gasoline powered boats
LED light is ON when batteries are combined
Dual Sensing?senses charge source on either battery bank
Includes a remote indicator LED with mounting bezel
Snap-on insulating cover
Automatic Three Stage Charging
The BatteryLink® Charger uses a three stage automatic charging profile. The three stages are referred to as bulk, absorption, and rest/float. The charger will move between these stages automatically, with no user intervention. When the charger starts, it goes first to the bulk stage. This is where the first 75% ? 80% of charging takes place. It is a constant current mode, in which the charger outputs as much current as it can to drive the voltage of the battery up to the absorption voltage. Once the absorption voltage is reached, the charger enters absorption mode. This is a constant voltage mode, in which the battery is held at the absorption voltage to complete the last 20% ? 25% of charging. In the absorption stage, current will decrease according to the Batteries? needs plus any additional current required for active loads. The length of time spent in the absorption stage will vary based on battery type, battery capacity, and the presence of loads, but will be a minimum of 1 hour up to a maximum of 5 hours. After the absorption stage, the charger will move to the rest/float stage. The float stage is a constant voltage mode intended to maintain fully charged batteries while supplying current for loads as necessary. The rest mode is included as an energy saving mode, and for compliance with California Energy Commission (CEC) requirements. In the rest stage, the charger output and ACR are turned off to conserve energy, and the battery voltages are monitored. If loads or self-discharge on either battery cause the voltage to drop to 12.9V, the charger enters float mode for 4 hours in order to maintain the battery and supply current to loads. After seven days of continuous rest/float mode, the charger will repeat the normal charge cycle to assure good battery health. Battery Temperature Compensation Battery temperature compensation is output voltage regulation based on battery temperature variances. Since batteries can see extreme temperature differences, it is important to regulate output voltage with temperature to maximize battery life. A battery in a cold environment should not be charged at the same voltage as a battery in a hot environment. The BatteryLink® Charger is set at a baseline of 25øC. If the included battery temperature sensor is installed, then every 5øC variance from this baseline will result in a change in output voltage. Voltage will decrease at higher temperatures, and increase at lower temperatures. The temperature sensor also allows the charger to react to extreme hot or cold temperatures (below 0øC or above 45øC) by reducing output or shutting down to preserve the battery. Reference the Installation Instructions on page 6 and the Full Installation Diagram on page 8 for details on how to install the battery temperature sensor.
Automatic Charging Relay (ACR)
The BatteryLink® Charger includes an integrated 65A Automatic Charging Relay (ACR). The purpose of an ACR is to combine batteries for charging, but leave them isolated for discharge. This works well with dual battery systems, where non-starting loads are isolated from the engine starting battery to reduce the risk of being stranded on the water without enough power to start your engine. The ACR in the BatteryLink® Charger will combine the auxiliary and start batteries at or away from the dock. This means both batteries will be charged during AC powered charging, or when AC power is not available and a secondary charging source is active, such as your engine?s alternator. The ACR includes an optional Start Isolation feature, which can be used to prevent engine starting current being drawn from the auxiliary battery. Start Isolation protects sensitive electronics wired to the auxiliary battery from being affected by voltage sags or spikes caused by engine starting.
