About G750. The NOCO Genius® G750 represents some of the most innovative and advanced technology on the market, making each charge simple and easy. It is quite possibly the safest and most efficient charger you will ever use. The G750 is designed for charging all types of 6V & 12V lead-acid batteries, including Wet (Flooded), Gel, MF (Maintenance-Free), CA (Calcium), EFB (Enhanced Flooded Battery), and AGM (Absorption Glass Mat) batteries. It is suitable for charging battery capacities from 2 to 30 Amp-Hours and maintaining all battery sizes.

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 G750 is a direct wall plug-in charger, and it is important to keep in mind the distance to the battery. The DC cable length from the charger, with either the battery clamp or eyelet terminal connectors, is approximately 75-inches (1,900mm).

Charging Modes. The G750 has three (3) modes: Standby, 12V NORM, and 6V NORM. 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. “Press and Hold” are indicated on the charger by a red line. 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:

Mode Explanation
Standby	In Standby mode, the charger is not charging or providing any power to the battery. Energy Save is activated during this mode, drawing microscopic power from the electrical outlet. When selected, an orange LED will illuminate.
	No Power
12V NORM	For charging 12-volt Wet Cell, Gel Cell, Enhanced Flooded, Maintenance-Free and Calcium batteries. When selected, a white LED will illuminate.
	14.5V | 750mA | 2-30Ah Batteries
6V NORM Press & Hold	For charging 6-volt Wet Cell, Gel Cell, Enhanced Flooded, Maintenance-Free and Calcium batteries. When selected, a white LED will illuminate.
	7.25V | 750mA | 2-30Ah Batteries

Using 6V NORM. [Press & Hold]

6V NORM charge mode is designed for 6-volt lead-acid batteries only, like Wet Cell, Gel Cell, Enhanced Flooded, Maintenance-Free and Calcium batteries. Consult the battery manufacturer before using this mode.

CAUTION. THIS MODE IS FOR 6-VOLT LEAD-ACID BATTERIES ONLY.

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.

Understanding Charge LEDs.

The charger has one (1) Charge LED. This Charge LED indicates the connected battery(s) state-of-charge (SOC). See the explanation below:

LED Explanation
Pulsing Red LED	The Charge LED will slowly pulse “on” and “off” when the battery is less than 75% fully charged.
Pulsing Green LED	The Charge LED will slowly pulse “on” and “off” when the battery is less than 90% charged.
Solid Green LED	When the battery is 100% charged, the Charge LED will be solid green.
Maintenance Green LED	During maintenance charging, the 100% Charge LED will pulse “on” and “off” slowly. When the battery is topped off and fully charged again, the 100% Charge LED will turn solid green. The charger can be left connected to the battery indefinitely.

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).

Error Reason/Solution
Single Flash	Battery will not hold a charge. Have battery checked by a professional.
Double Flash	Possible battery short. Have battery checked by a professional.
Triple Flash	Battery voltage is too high for the selected charge mode. Check the battery and charge mode.
Error LED Solid Red	Reverse polarity. Reverse the battery connections.
Standby Solid Orange	Battery voltage is too low for charge to detect or charger is in supply. Jumpstart the battery to raise the battery voltage.

Step 1 & 2: Analyze & Diagnose

Checks the battery's initial condition, including voltage, state-of-charge and health, to determine if the battery is stable before charging.

Step 3: Recovery

Initializes the Recovery desulfation process (if needed) for deeply discharged or sulfated batteries by pulsing small amounts of current.

Step 4: Initialize

Starts the charging process with a gentle (soft) charge.

Step 5: Bulk

Begins the Bulk charging process based on the condition of the battery and returns 80% of the battery's capacity.

Step 6: 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.

Step 7: 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.

Step 8: 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.

Charging Times.

The estimated time to charge a battery is shown below. The size of the battery (Ah) and its depth of discharge (DOD) greatly affect its charging time. The charge time is based on an average depth of discharge to a fully charged battery and is for reference purposes only. Actual data may differ due to battery conditions. The time to charge a normally discharged battery is based on a 50% DOD.
