The rugged NOCO Genius GENPRO series on-board smart charger quickly charges and maintains your 12-volt lead-acid or lithium-ion batteries. Multiple battery bank efficiently charges deep cycle and starter batteries up to 230 amp-hours. It's great for boats, trolling motors, generators, and a wide range of electric vehicles and industrial equipment. With a fully submersible design, this smart charger was built to handle harsh marine environments, while keeping your batteries in peak condition.


User-Friendly Interface with LED Indicators

NOCO Genius GENPRO10X3 LED Charging Indicators

This Genius smart charger was designed to provide a simple, user-friendly experience. The mode button allows you to easily cycle through the unit's charge settings. Back-lit LED indicators let you verify that the unit is operating correctly, and they allow it to be easily operated at night. These indicators signal the unit's charge status, selected charging mode, and alert you to potential performance issues or errors.


NOCO Genius GENPRO10X3 Advanced Battery Error Diagnostics

These indicators allow you to quickly identify a problem with the battery or connection. So you don't have to waste time guessing if the battery voltage is too high or too low for your selected mode, or worry about damage from a reversed polarity connection to a battery.


4 Battery Charging Modes for 12V Batteries

NOCO Genius GENPRO10X3 Battery Charger Charging Modes Explained

This Genius smart charger has 4 selectable charging modes that let you quickly switch between charging different lead-acid and lithium-ion battery types. 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. This NOCO charger gives you the versatility to tackle different battery types and charging situations in one charger.


The charger works with 12V wet cell, gel cell, enhanced flooded, calcium, maintenance free, AGM, and lithium-ion batteries with battery management systems (BMS). A built-in battery desulfator restores lost capacity to sulfated and old batteries.


Heavy-Duty Eyelet Connectors

Sets of 3/8" eyelets connect the charger to your batteries. Over-molded connection points stand up to heavy usage and keep connections safe from the elements. Built-in 15-amp MINI fuses protect each connection against dangerous overcurrent.


Quickly Charge and Maintain Batteries from 120V to 240V AC Power Source

This Genius charger plugs into an available wall outlet to quickly charge and maintain multiple batteries. High-frequency switch-mode technology converts AC power into safe DC power to fully charge batteries. An onboard microcomputer monitors and controls this charging process to minimize power loss and maximize efficiency. Included hardware lets you mount the unit in an enclosed compartment, garage, or workspace.

The table above provides a quick reference for how long it will take the unit to charge batteries with various amp-hours.


Rugged Submersible Design

NOCO GENPRO10X3 Waterproof and Ignition Proof Design

This on-board charger was built to handle extreme marine conditions. The unit has an IP68 rating, which means it can handle being fully submerged in water, and it's protected against solid particles like dust or sand. Its ignition protected for safe and worry-free operation around marine engine compartments and fuel tank spaces. Saltwater won't cause issues either. The charger has been thoroughly tested to resist corrosion.


The housing is made from tough Lexan resin that protects the internal electronics against vibration and impacts. The unit can handle being dropped, kicked over, and just about anything else your day brings.


AC Port Plug for Plug-and-Play Charging

NOCO GEN Series GCP AC Port Accessory

Available AC port plugs (sold separately) from NOCO let you easily setup your GENPRO series charger for plug-and-play charging with any extension cord. The plug creates a "pass through" AC charging port on a surface, so you can quickly connect to the charger when it's mounted inside a compartment on a truck, boat, trailer or RV. This allows you to easily access the charger for charging engine block heaters, trolling motors, batteries, and other equipment. A snap-fit cap creates a watertight seal to protect the connection whenever you're done.

Video Transcript for Review of NOCO Battery Charger - 3 Battery On-Board Charger - NOC74FR

Hi there, I'm Michael with etrailer.com. Today, we're going to take a quick look at this NOCO GENPRO onboard battery charger. This is an AC to DC smart charger that's going to quickly charge and maintain up to three 12 volt batteries. This is going to be completely sealed and got a waterproof design with an IP rating of 68. So it is fully submergible. So it's going to be great for your Marine applications.

It's even tested to resist saltwater corrosion, so it's going to fit a wide variety of uses, including for your boats, trolling motors, generators, electric vehicles and industrial equipment. So lots of different options for this depending on where you're needing it. This is going to have multiple battery profiles. So it's going to allow you to charge up a variety of battery types. So on each of these three connectors for our batteries, we've got an option for your 12 volt, 12 volt mode and that's going to be for your normal batteries like the wet cell, gel cell, enhanced flooded, maintenance free and calcium batteries.

Then you've got your AGM 12 volt. So that's for your AGM batteries. And then your 12 volt lithium ion. If you are using a lithium ion battery, you will need to have a battery management system, but you're gonna have those modes for all those different kinds of batteries. And then we're also going to have a force mode which is going to allow us to charge batteries that are below one volt.

So it's going to help us to kind of manually override the safety limits to get those really low batteries charged up again. We also have a recovery mode that's going to help repair old stratified and sulfated batteries. So if your batteries not as healthy as it could be, that repair mode will help to get that back up and operational and at full capacity again, or at least an improved capacity. This does have a multi stage charging algorithm. That's going to charge your batteries up two times faster than your traditional chargers without overcharging the batteries.

So it's going to analyze your batteries' condition to provide that custom charge so that it's meeting the needs of the battery. It's got a built-in battery desulfator. That's going to help restore lost battery capacity for your battery. So it's going to make sure that your batteries are nice and healthy, and you've got that option for the different kinds with each of these connections. So if you, for some reason, you have three different kinds of batteries, you can switch those modes independently. So a lithium battery here, and the AGM there, wet cell. Whatever the case may be, you can switch that up to accommodate different kinds of batteries. You can see this does have these back lit indicators on here. This is going to help signal your units charged status. So those bars there will show you if you're 25%, 50%, 75 and a hundred percent charged. With those little indicators across the top there, it's also going to allow you to see your charge modes. So those different modes that I was talking about, those will light up depending on which mode you're in. And it will also alert you to any potential performance issues with these indicators down here. So whether it's your battery voltage is too low to be detected, or if the voltage is too high for your selected mode and you need to switch to a different one. Or if there's a short in the battery, or the cables are connected wrong you got a reverse polarity issue. Or if the unit temperature is either too high or too low, you're going to get those indicators there for each of these so that you can see what's going on, what's wrong and get that fixed. This will connect to your batteries with these three eighths inch islet connectors. These are going to provide maximum amount of contact with your terminal. So you're going to have nice solid connection. Each one is also going to have a 15 amp fuse built in to help protect your electronics from any overloads. Each cable is about 72 inches long. So you'll have a little bit of a reach there to get those connected to your batteries or AC cable. Just plug right into your normal wall charger. It's got a 72 inch cable length as well. So you can get that plugged in. There's also an option to pick up a port that will allow you to get this mounted on your boats or the side of your trailer whatever it may be, wherever you're planning on using this. That AC port will be more of a permanent installation so that you can get that mounted on the outside. So then all you have to do is run an extension cord from your wall in your garage or wherever it is you're storing your unit and then plug it into the outside there rather than having to open it up, run that extension cord in or what have you. Very easy to get connected if you have that port, which is sold separately, but a nice little add on in my opinion. As far as our dimensions go, our unit here is right about 10 and a half inches long, approximately eight and three quarters of an inch wide. When I measured that, I measured how much room you're gonna need for your cables here. Cause obviously you don't want them to be bent at too sharp an angle. But you are going to need a little bit of room for those. So from about the edge of the table here, out to the edge of the unit, it's about eight and three quarters of an inch. And then our thickness, we're just shy of three inches. So about two and seven eighths of an inch. They do have channels here so that you can get this mounted. Include some couple of screws that you can get back mounted in place. So very nice option here. If you have three batteries that you're wanting to get charged up independently, this is going to be a great system for you. So it's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..

Great charger-maintainer for a group 31 AGM battery, I would caution it's use on smaller batteries, especially anything smaller than a group 24.
