About GX Series Chargers. The NOCO Genius® GX Series of chargers represents some of the most innovative and advanced technology on the market, making each charge simple and easy. The GX is designed for charging all types of 24V, 36V or 48V lead-acid and lithium-ion battery systems, including Wet (Flooded), Gel, MF (MaintenanceFree), CA (Calcium), EFB (Enhanced Flooded Battery), AGM (Absorption Glass Mat), and LIB (Lithium Ion) batteries. It

is suitable for charging battery capacities from 25 to 500 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 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.

Mode		Explanation
	In Standby mode, the charger is not
	charging or providing any power to
Standby	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
	For charging Wet Cell, Gel Cell,
NORM	Enhanced Flooded, Maintenance-Free
	and Calcium batteries. When selected,
	a white LED will illuminate.
GX2440	28.8V	± 0.3V | 40A ± 1A
GX3626	43.2 +/- 0.45V |		26A ± 1A
GX4820	57.6V	+/- 0.6V |	20A ± 1A
COLD/	For charging batteries in cold
	temperatures below 50ºF (10ºC) or
AGM	AGM batteries. When selected, a blue
	LED will illuminate.
GX2440	29.4V	± 0.3V | 40A ± 1A
GX3626	44.1V	+/-0.45V |	26A ± 1A
GX4820	58.8V	+/-0.6V |	20A ± 1A

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.

Mode		Explanation
AGM+	For charging advanced AGM batteries,
	which requires a higher than normal
Press & Hold	charging voltage. When selected, a
	blue LED will illuminate.
GX2440	31.2V	± 0.3V | 40A ± 1A
GX3626	46.8V	+/- 0.4V	|	26A ± 1A
GX4820	62.4V	+/-0.6V	|	20A ± 1A
LI-ION	For charging lithium-ion batteries,
	including lithium iron phosphate. When
Press & Hold	selected, a blue LED will illuminate.
GX2440	29.2V	± 0.3V | 40A ± 1A
GX3626	43.8V	+/-0.45V |		26A ± 1A
GX4820	58.4V	+/- 0.6V		| 20A ± 1A
	An advanced battery recovery mode
REPAIR	for repairing and storing, old, idle,
	damaged, stratified or sulfated
Press & Hold	batteries. When selected, a red LED
	will illuminate and flash.
GX2440	32V ± 0.3V | 5A ± 1A
GX3626	48V +/-0.45V | 5A ± 1A
GX4820	64V +/-0.6V | 5A ± 1A
SUPPLY	Converts to a DC power supply. When
Press & Hold	selected, a red LED will illuminate.
GX2440	27.2V	± 0.3V | 20A ± 1A
GX3626	40.8V	+/-0.45V		| 13A ± 1A
GX4820	54.4V	+/-0.6V |		10A ± 1A

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
