NOCO GX2440 Industrial Battery Charger with LED Interface

The GX2440 was designed to provide a simple, user-friendly experience. Back-lit LED indicators let you verify that the unit is operating correctly, and allow it to be easily operated at night. These indicators signal the battery's charge status and alert you to potential performance issues or errors. This allows you to identify if the unit is too hot or cold for operation or detect a reversed polarity connection to a battery.

NOCO GX2440 Tamperproof Interface

The touch-button interface allows you to turn the unit on or off and select your charging mode. A plastic cover twists into position over the interface to deter others from changing the settings while the charger is in use. Once the cover is secured into position you don't have to worry about anybody accidentally hitting the mode button.

6 Charging Modes for 24V Batteries

The GX2440 has 6 charging modes that cover a wide range of applications, ensuring it will hold its value down the road as your needs change. Traditional battery chargers generally only work with a specific battery type, like lithium-ion or AGM batteries, or only in special circumstances like charging in cold environments. The NOCO GX2440 gives you the versatility to tackle different battery types and charging situations in one charger.

6 Charging Modes for 48V Batteries

The GX2440 has 6 charging modes that cover a wide range of applications, ensuring it will hold its value down the road as your needs change. Traditional battery chargers generally only work with a specific battery type, like lithium-ion or AGM batteries, or only in special circumstances like charging in cold environments. The NOCO GX2440 gives you the versatility to tackle different battery types and charging situations in one charger.

NOCO GX2440 Industrial Battery Charger 6 Charging Modes

The table above details the available charging profiles and applications for the GX2440. The charger works with 24V wet cell, gel cell, enhanced flooded, calcium, maintenance-free, AGM, and lithium-ion batteries with battery management systems (BMS). The 24V repair mode lets you restore lost capacity to sulfated and old batteries. Supply mode provides a DC power supply for troubleshooting low-voltage batteries or equalizing unbalanced battery systems.

Multi-Stage Smart Charging Technology

The NOCO GX2440 smart charger uses a 9-stage charging cycle to quickly and efficiently charge your battery. This ensures that the battery safely reaches maximum capacity without being overcharged.

NOCO GX2440 Industrial Battery Charger Advanced Smart Charging Technology

In the first step of the charging process, the charger will analyze the battery's condition and state of charge. The charger then uses this data to diagnose the battery's health and ensure it can be safely charged. If the battery is deeply discharged or sulfated, the charger will automatically enter the recovery stage to repair the battery by pulsing small amounts of current.

Once the unit has determined the battery's condition is stable, it will initialize the charging process by providing a constant, gentle charge. Entering the opportunity stage, it begins charging at a high current. As the charger enters the bulk stage, it adjusts to the battery and slowly steps down the charge for optimal charging, and brings the battery to 80-percent capacity.

As the battery nears full charge, the GX2440 enters the absorption stage and delivers small amounts of current to limit battery gassing and safely bring the battery to 90-percent capacity. The charger will then begin optimization of the battery, bringing it to full capacity and optimizing it for increased run time and performance.

The final step of the charging process, maintenance, monitors the battery for drops in power and supplies the correct current to keep it fully charged. If a drop in voltage is detected, the charger will begin the optimization cycle to keep the battery fully charged.

Heavy-Duty Eyelet Connectors

NOCO GX2440 Heavy-Duty Eyelets

Extra-large 13/32" eyelet connectors mount directly to your battery's terminals. The lie-flat design ensures maximum contact with terminals to optimize current transfer. A built-in 50-amp fuse protects your connection against dangerous overloads.

Rugged Industrial Design

NOCO GX2440 Rugged Batery Charger for Industrial Applications

The GX2440 was built to handle tough industrial and commercial environments. The unit has an IP66 rating, which means it can withstand multi-directional, low-pressure water jets and is completely sealed against dirt, dust, oil, and other non-corrosive materials. The aluminum housing resists corrosion and withstands shock and vibration for endless hours of operation. Heavy-duty strain reliefs reduce stress on the cables and stand up to heavy usage.

Interchangeable Connections for Custom Charging Configurations

NOCO GX4820 Universal Input with AC and DC Cables

The GX2440 was designed for flexible operation around the worksite with a full line of available GX accessories (all sold separately). The charger's input and output cables can be changed out to match your specific application. This means you can swap out the eyelets for other connections like an Anderson SB50, 2-pin, 3-pin, or Powerhouse D-type plug. You can also swap out the standard AC plug for other AC input configurations (sold separately) should work take the charger abroad.

Auxiliary Port for Remote LEDs

NOCO GX2440 Optional Remote LED Configuration to Signal Charging Modes

The GX2440 comes with a remote LED auxiliary port that can be used to connect external LEDs (sold separately) to let you monitor charging. This is great for keeping tabs on the unit's operation when the charger's interface and LEDs are not accessible. The port supports 2 LEDs, and it reverses the polarity between the charging identifier and the error indicator.

Video Transcript for NOCO Battery Chargers - Battery Charger - 329-GX2440 Review

Speaker 1: Today, we're going to take a look at the NOCO Genius 24 Volt UltraSafe Industrial Battery Charger. This is a portable automatic battery charger and maintainer. It helps you keep a charge on both deep-cycle lead-acid and lithium-ion batteries. It is designed for charging 24-volt batteries. It's ideal for batteries up to 425 amp hours. It's perfect for charging electric vehicles like a golf cart, scissor lift, pallet jack; and it is suitable for both on- and off-board applications.

It can also be used to maintain a full charge on your batteries.It has a waterproof, tamper proof interface cover here that you can just unscrew to access your mode button and your LEDs. I'm going to go ahead and zoon in, so we can talk about this interface right up here. The mode button right here that you push allows you to select which charging mode is needed. This is a versatile 6-in-1 battery charger. You simply push the button there to switch the charging modes.

Over here are your six charging modes, and they have LED indicators next to them that illuminate when the charging mode is selected.At the very top, it starts with the 24-volt norm mode. Second one down, is a 24-volt cold/AGM mode. Then you go down to a 24-volt AGM+ mode. Then the 24-volt lithium-ion mode. Then the two bottom modes.

One is a repair mode, and one is a supply mode. It does have an auto memory feature, which will remember the last charging mode if accidentally unplugged or if power is lost.Over here, it does have the charge level LEDs that'll light up. It adds a visual to the amount of charge on your battery. It has separate LEDs for 25%, two LEDs for 50%, three for 75%, and it will show all four for 100%. It does use advanced diagnostics to analyze your battery feedback.

It displays a particular error pattern if a problem is detected. Right here there is an error LED and a standby LED. Basically, it will flash between the error LED and standby LED. You can tell by the flash what the error is. It has a single flash, double flash, triple flash, quadruple flash; or it will just have an error LED solid red, or a standby LED solid orange.I'm just going to go ahead and zoom back out, and we can talk about it. It does use built-in battery maintenance technology. It monitors your battery activity. It begins charging when needed. It allows for continuous operation without supervision, and there's zero risk of over charging your battery. The inhibit function on it will prevent electric vehicles from moving while charging and accidental damage to the connecting cabling system. The inhibit port will contain an 20-amp relay that closes when connected to AC power and will disable the vehicle.It does have a built-in battery desulfator to rejuvenate your under performing batteries. It recovers deeply discharged batteries down to 2 volts. It is a compact, powerful charger. It efficiently converts AC power into safe DC power for battery charging. The on-board microcomputer will control charging to minimize power loss. It is designed to work with the interchangeable X-Connect battery accessories that we sell separately on our website. They provide quick and easy accessory changes.Power consumption on this is 960 watts maximum. The DC cable, right over here, is fused with a 50-amp fuse. It does have the eyelets, you can see on the end, for connecting. DC cord length is 76". The AC cable over here has the type A plug included, and the AC cord length is also 76". A few measurements on this. The overall length is about 12". Overall width is right about 8 1/2" wide. The total depth on it is about 3 7/8" deep.I'm just going to take our cover and go ahead and screw that back on. It does come with a nice user's guide and a couple extra strain 00:03:53 release, if you have to do any replacing of those. That should do it for the review on the NOCO Genius 24 Volt UltraSafe Industrial Battery Charger.

  • Can Badlands 2500 Winch be Wired to 110 AC Power Source
    We have winches with similar capacities to the Badlands 2500 you have that are designed to be used with 110 AC power like the Dutton Lainson StrongArm part # DL24872 but I can't recommend attempting to connect a DC winch to an AC power source unless you used an AC to DC converter like the 40 amp part # 329-GX2440.
