Getting Started

Before using the charger, carefully read the battery manufacturer’s specific precautions and recommended rates of charge for the battery. Make sure to determine the voltage and chemistry of the battery by referring to your battery owner’s manual prior to charging.

Mounting

The GX Series Chargers have four (4) external holes for mounting. Make sure there are no obstructions behind the mounting surface. It is important to keep in mind the distance to the battery. Allow for 12-inches (304mm) of slack in cables between connections.

Charging Modes

The GX Series Chargers have seven  (7) modes: Standby, NORM, COLD/AGM, AGM+, LI-ION, REPAIR and SUPPLY.  Some charge modes must be pressed and held for three (3) seconds to enter the mode. These “Press and Hold” modes are advanced charging modes that require your full attention before selecting. It is important to understand the differences and purpose  of each charge mode. Do not operate the charger until you confirm the appropriate charge mode for your battery. Below is a brief description:

Basic Charging Modes 
Voltage and current depend on model of charger. Specifications for each model are listed below.

CAUTION: ALWAYS VERIFY THE VOLTAGE OF A BATTERY SYSTEM BEFORE ATTEMPTING TO CHARGE. ONLY USE THE GX SERIES CHARGER THAT IS DESIGNED FOR THE SAME VOLTAGE AS YOUR BATTERY SYSTEM. 

Advanced Charging Modes 
IMPORTANT: Advanced Charge Modes are modes that require the users full attention when selecting. 

Using AGM+. [Press & Hold]
AGM+ charge mode is designed for advanced AGM batteries only. Advanced AGM batteries are a new battery technology. These batteries accept a higher than normal charging voltage. AGM+ charge mode is NOT suitable for traditional AGM batteries. Consult the battery manufacturer before using this mode.
CAUTION: USE THIS MODE WITH CARE. THIS MODE IS FOR LEAD-ACID ADVANCED AGM BATTERIES ONLY. THIS MODE USES A HIGH CHARGING VOLTAGE AND MAY CAUSE SOME WATER LOSS IN WET  (FLOODED) CELL BATTERIES OR OVERCHARGE IN SOME BATTERIES.

Using LI-ION. [Press & Hold]
LI-ION charge mode is for lithium-ion batteries only, including lithium iron phosphate batteries. 
CAUTION: THIS MODE IS FOR LITHIUM BATTERIES ONLY. LITHIUM-ION BATTERIES ARE MADE AND CONSTRUCTED IN DIFFERENT WAYS AND SOME MAY OR MAY NOT CONTAIN A BATTERY MANAGEMENT SYSTEM (BMS). CONSULT THE LITHIUM BATTERY MANUFACTURER BEFORE CHARGING AND ASK FOR RECOMMENDED CHARGING RATES AND VOLTAGES. SOME LITHIUM-ION BATTERIES MAY BE UNSTABLE AND UNSUITABLE FOR CHARGING. 

Using Repair [Press & Hold]
Repair is an advanced battery recovery mode for repairing and storing, old, idle, damaged, stratified or sulfated batteries.  Not all batteries can be recovered.  Batteries tend to become damaged if kept at a low charge and/or never given the opportunity to receive a full charge. The most common battery problems are battery sulfation and stratification.  Both battery sulfation and stratification will artificially raise the open circuit voltage of the battery, causing the battery to appear fully charged, while providing low capacity.  Use Repair in attempt to reverse these problems. For optimal results, take the battery through a full charge cycle, bringing the battery to full charge, before using this mode. Repair can take up to four (4) hours to complete the recovery process and will return to Standby when completed. 
CAUTION: USE THIS MODE WITH CARE. THIS MODE IS FOR LEAD-ACID BATTERIES ONLY. THIS MODE USES A HIGH CHARGING VOLTAGE AND MAY CAUSE SOME WATER LOSS IN WET (FLOODED) CELL BATTERIES. BE ADVISED, SOME BATTERIES AND ELECTRONICS MAY BE SENSITIVE TO HIGH CHARGING VOLTAGES. TO MINIMIZE RISKS TO ELECTRONICS, DISCONNECT THE BATTERY BEFORE USING THIS MODE.

Using Supply [Press & Hold]
Supply converts the charger to a constant current, constant voltage DC power supply. To enter Supply Mode, the charger must not be connected to the battery.
CAUTION. THIS MODE IS FOR LEAD-ACID BATTERIES ONLY. PRIOR TO USE, READ YOUR DEVICE MANUAL TO DETERMINE IF IT IS SUITABLE FOR USE WITH THIS MODE. BOTH THE SPARK PROOF AND REVERSE POLARITY SAFETY FEATURES ARE DISABLED IN THIS MODE. DO NOT ALLOW THE POSITIVE AND NEGATIVE BATTERY CLAMP OR EYELET TERMINAL CONNECTORS TO TOUCH OR CONNECT TO EACH OTHER AS THE CHARGER COULD GENERATE SPARKS. CHECK THE POLARITY OF THE BATTERY TERMINALS BEFORE USING THIS MODE.

Cable Connections
The GX Series Chargers have  AC and DC connection ports that are designed to allow the user to choose custom cables to fit the desired application. Both the AC and DC connection ports are labeled to inform the user the proper way to install custom cables.

AC Input Connection Port
The AC Input Connection Port requires line (black), return (white) and ground (green) connections. The unit must  be grounded for safe operation. 16AWG minimum wire gauge is required. Make sure all connections are securely tightened and insulated from each other before operation. To increase the charger’s waterproofing, completely seal the entire connection with electric sealant.  

DC Output Connection Port
The DC Out Connection Port requires positive (red), and negative (black) connections. 10AWG minimum wire gauge is required. Make sure all connections are securely tightened and insulated from each other before operation. To increase the charger’s waterproofing, completely seal the entire connection with electric sealant.

  Inhibit Port (Optional For Operation)
The Inhibit Port contains a Relay rated at 20A. When the Charger has AC power, the relay will close allowing current flow. When the charger is removed from AC power, it takes approximately 15 seconds for the capacitors to discharge and the relay to open.

Remote LEDs Port (Optional For Operation)
The Remote LEDs Port can be used to connect LEDs for easy monitoring when the charger’s LEDs are not accessible. The port supports two LEDs, reversing polarity to change from “Charging” to “Charged.”  

Connecting to the Battery
Do not connect the AC power plug until all other connections are made. Identify the correct polarity of the battery terminals on the battery. The positive battery terminal is typically marked by these letters or symbol (POS,P,+). The negative battery terminal is typically marked by these letters or symbol (NEG,N,-). Do not make any connections to the carburetor, fuel lines, or thin, sheet metal parts. The below instructions are for a negative ground system (most common). If your vehicle is a positive ground system (very uncommon), follow the below instructions in reverse order.

1. Connect the positive (red) battery clamp or eyelet terminal connector to the positive (POS,P,+) battery terminal. 
2. Connect the negative (black) battery clamp or eyelet terminal connector to the negative (NEG,N,-) battery terminal or vehicle chassis. 
3. Connect the battery charger’s AC power plug into a suitable electrical outlet. Do not face the battery when making this connection.
4. When disconnecting the battery charger, disconnect in the reverse sequence, removing the negative first (or positive first for positive ground systems).

Begin Charging

1. Verify the voltage and chemistry of the battery.
2. Confirm that you have connected the battery clamps or eyelet terminal connectors properly and the AC power plug is plugged into an electrical outlet.
3. The charger will begin in Standby mode, indicated by an orange LED. In Standby, the charger is not providing any power. 
4. Press the mode button to toggle to the appropriate charge mode (press and hold for three seconds to enter an advanced charge mode) for the voltage and chemistry of your battery.
5. The mode LED will illuminate the selected charge mode and the Charge LEDs will illuminate (depending on the health of the battery) indicating the charging process has started.
6. The charger can now be left connected to the battery at all times to provide maintenance charging.

User Interface

Understanding Charge LEDs

The charger has four (4) Charge LEDs per bank - 25%, 50%, 75% and 100%. These Charge LEDs indicate the connected battery(s) state-of-charge (SOC). See the explanation below: 

The RED LEDs will gradually spin slower as the battery charges.

Understanding Advanced Diagnostics

Advanced Diagnostics is used when displaying Error Conditions.  It will display a series of blink sequences that help you identify the cause of the error and potential solutions. 
All Error Conditions are displayed with the Error LED and Standby LED flashing back and forth. The number of flashes between each pulse denotes a potential Error Condition (except reverse polarity and low-voltage battery).

• Opportunity Charging: Designed to rapidly charge batteries in applications where charging is intermittent between use.

Charging Steps

1. Analyze & Diagnose
   Checks the battery’s initial condition, including voltage, state-of-charge and health, to determine if the battery is stable before charging.
2. Recovery
   Initializes the Recovery de-sulfation process (if needed) for deeply discharged or sulfated batteries by pulsing small amounts of current.
3. Initialize
   Starts the charging process with a gentle (soft) charge.
4. Opportunity & Bulk
   Begins with opportunity charging at a high current, then steps down to the Bulk charging process based on the condition of the battery and returns 80% of the battery’s capacity.
5. Absorption
   Brings the charge level to 90% by delivering small amounts of current to provide a safe, efficient charge. This limits battery gassing and is essential to prolonging battery life.
6. Optimization
   Finalizes the charging process and brings the battery to maximum capacity.  In this step, the charger utilizes multi-layered charging profiles to fully recapture capacity and optimize the specific gravity of the battery for increased run time and performance. The charger will switch to Maintenance if the battery tells the charger that more current is needed.
7. Maintenance
   Continuously monitors the battery to determine when a maintenance charge should be initiated. If the battery voltage falls below its target threshold, the charger will restart the Maintenance cycle until voltage reaches its optimal state and then discontinues the charge cycle. The cycle between Optimization and Maintenance is repeated indefinitely to keep the battery at full charge. The battery charger can be safely left connected indefinitely without the risk of overcharging.
