Follow the guidelines provided in this manual to install your Battery Charger.
The battery charger will automatically fully charge and condition your batteries to 

ensure your batteries last a long time and you get the most out of them. When you 

are not at home, always leave your charger plugged in to reduce sulfate build-up 

allowing your batteries to be fully charged and automatically maintained for your 

next fishing trip.
The design of the charger incorpo-

rates a storage recondition mode 

that stimulates and re-conditions 

your on-board batteries for 3 hours 

once a month and when completed 

will resume its normal energy 

saver auto maintain mode. During 

this mode the storage recondition 

LED under Charge Mode will 

illuminate green but with a fade-in 

fade-out pulse, indicating storage 

recondition mode is active with the green auto maintain LED under Charge Mode 

still illuminated, indicating your batteries remain fully charged during this process.

Overview of the Charge Mode Indicators

Each LED will sequentially illuminate after the previous mode is completed.

Initializing LED (Blue):

After the installation of the charger is complete and you 

have supplied the AC power to the unit, the Initializing LED starts flashing blue,  

indicating that  the charger is in process of Initializing . The Initializing procedure 

involves checking the connections, polarity and that the battery(s) connected are 

over 2.5 VDC and are able to accept a charge.
The Initializingstage may take up to two minutes.

     System Check LED (solid green) :

If all tests have passed successfully, the 

System Check LED lights solid green,indicating your charger is installed properly 

and your batteries are capable of being charged followed by the charging process.

Fast Charging LED (solid red):

During charging the fast charging LED lights solid red.

Optimizing LED (solid amber):

During optimizing the Optimizing LED lights solid amber.

Maintaining - Energy Saving Mode LED (solid green):

Maintaining LED lights 

green, indicating the batteries are being monitored to automatically maintain your 

fully charged battery(s) during short or long term storage periods.

The LED Display and Charge Monitor

The battery charger includes 6 LEDs for operation status 

(Charge Mode, Charge Monitor, and System Check), up to 3 

battery bank fault LEDs (bank1, bank2 and bank3 under 

Battery Trouble Status) depending on the model, battery type 

selection LED.

Installation

When connecting each jacketed battery charger cable, make sure it is connected

to only 

one

 

12 VDC battery

 and observe the polarity and color of all connections:

    • Red Wire to the “+” (Positive) Battery connection

    • Black Wire to the “-” (Negative) Battery connection
The black wire can never be connected to a terminal with red wires and vice 

versa. 

Important: The pair of red and black wires in 1 cable jacket MUST GO TO 

THE SAME 12VDC battery.
