Your battery charger features a clean geometric design executed with a heavy duty 

extruded aluminum housing allowing for increased power and performance. 

Incorporation of microprocessor and software control adds the latest pulse charging 

technology resulting in cooler operation and faster charge times. Your charger is 

fully automatic with a multi-stage digital performance charging profile that includes 

5 sequential stages: Initializing, Fast Charging , Optimizing, Maintaining , Smart 

storage; that is safe for short and long term storage. This process will not only 

enhance the performance of all 12 volts flooded and AGM lead acid batteries, it will 

also extend the lifetime of the batteries.

For the ease of use, the battery charger features a brand new intuitive user 

interface display with individual LED indicators for each charging mode, AC 

power-on diagnostics with a system check OK status indicator providing positive 

confirmation that the charger connections are healthy and that the batteries can be 

charged. The Digital Charge Monitor gauge indicates charging status progress 

during the operation with a single red LED, indicating low battery(s) are being 

charged. Dedicated battery fault indicators eliminate time consuming 

troubleshooting and clearly indicate individual battery wiring faults or if a battery is

less than 2.5 VDC and cannot accept a charge.

Our chargers automatically senses and distributes 100% of available charging 

amps to any or all of the banks as needed..

Energy Saving Mode: after fully charging and conditioning batteries, your charger 

will monitor and maintain batteries automatically only when needed to keep their 

full state of charge. This significantly reduces AC power consumption and lowers 

operating costs while maximizing battery performance.

The Battery Charger is compact, lightweight and prewired for each installation. The 

charger is 100% waterproof. Built with peace of mind safety every unit incorporates 

In-line DC fuses for all battery banks, over-voltage, overload, over-temperature, 

reverse polarity and ignition protection.

General Overview

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.
