NOCO GENPRO10X1 On-Board Marine Battery Charger Diagram

The rugged NOCO Genius GENPRO series on-board smart charger quickly charges and maintains your 12-volt lead-acid or lithium-ion battery. A single 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 GENPRO10X1 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 GENPRO10X1 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 GENPRO10X1 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

A set of 3/8" eyelets connect the charger to your battery. 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.

NOCO GENPRO On-board Battery Charger Charging Times Diagram

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 GENPRO10X1 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 - 10-amp Submersible Battery Charger - NOC44FR

Hi there. I'm Michael with Today, we're going to take a quick look at this NOCO gen pro 10 amp onboard battery charger. This battery charger is going to quickly charge and maintain an individual 12 volt battery. It is completely sealed. So it's gonna be a nice waterproof design.

It can be fully submerged for short periods of time. So it's going to be great for your marine applications. On your boats, trolling motors, those kinds of things. It does have that IP 68 rating. So it's going to keep out dirt, debris and moisture.

It is tested to resist salt water corrosion as well. So it is going to hold up really well. Can also be used for your electric vehicles or industrial equipment. Any 12 volt battery that you're gonna need to get charged. This is going to do a great job for you.

This does have a working voltage range of 120 to 240 volts of alternating current. So it is going to be great for your 12 volt batteries up to 230 amp hours. This does have multiple battery profiles. You can switch through here. So it does have a 12 volt mode for your wet cell, gel cell, advanced flooded and maintenance free batteries.

You can switch that to the AGM mode for your AGM batteries. And then you can also switch to the lithium ion for your lithium ion batteries. And now if you do have a lithium ion battery, your battery does need to have a battery management system in order to work with this. And then you can also switch it into the force mode to help charge up your dead batteries that are below one volt. This does have these nice indicators on here to help you identify which mode you're in and to help identify problems. If you have a connection to your battery problem, if the voltage is too high or too low in your selected mode or if there's a reverse polarity detected, it will alert you with those little light ups around the mode button there. So lots of great features here. It is going to be very easy to just plug right into your AC Wall port. It's got a 12, sorry, six foot long cord here. So it should work pretty easily for most applications. I would maybe suggest adding on the extension cord that you can see there. You can just easily mount that if you're putting this on a boat or on the outside of your RV or something like that. You can mount that on the outside. So then you just plug an extension cord into that port that you see there and that will get you connected. So rather than having to find a place to run your extension cord in or pull this out every time, it's just right there on the side. So you can easily plug in your extension cord and everything is gonna get powered up. But no matter what, if you just use this, or if you use that extension, this is going to provide a full charge output for your batteries. Even with a low or varying AC current input. So you're not gonna have to worry about your AC coming in. This will help to make sure that everything going into your batteries is in the appropriate format and whatnot. This does have a multistage charging algorithm. That's gonna help charge your batteries about two times faster than your traditional chargers. And it is going to monitor to make sure that it's not overcharging the batteries. Will analyze the batteries condition, make sure that it is getting the appropriate charge sent to the batteries. It does also have a built-in battery desulfator that's going to help to restore your batteries that have lost capacity. So really nice option there to help with those older batteries. This does connect to your 12 volt battery with the heavy duty three eights inch islet connectors. So that's going to provide a nice contact with your terminals. Again, our cable is right at six feet long and you can see this does have a 15 amp mini fuse on each of these to help to protect against any dangerous over current before it gets to your battery. This is going to have a maximum charging amp average of 10 amps. As I mentioned before, as far as our mounting and measurements go, you can see we do have slits on the side here so that we can get screws put in there, hold this in place. Our width, I'm going to say it's roughly five and three quarters of an inch wide. Our height, I'm going to include our cables here. But the shortest I could bend these, which probably isn't the best option, but the tightest spot that you could probably get this in, I would say is roughly six inches. Still having enough room for those cables to bend there. And then our thickness, just over two and three quarters of an inch. Probably exactly about, exactly two and 13 sixteenths according to my measurement. So just over two and three quarters of an inch thick. And it only weighs about four pounds. So it shouldn't be a very burdensome for you to get this mounted in place near your battery. Now, this is just going to be for your single battery. There are other options that are very similar to this but they support multiple batteries. So depending on your setup, if you just need the 10 amp for one battery to get charged up, one 12 volt battery. This is going to be a great option especially if you are needing that submergability. If you're using it on a boat or something like that. This is a really nice option for you. So that's gonna complete our look for today. Again, I'm Michael with Thanks for watching..

  • How To Charge 2-6v Batteries Wired In Series on Truck Bed Camper and Which Charger to Use
    I have a solution for you, but the NOCO GEN1 charger you've mentioned is not currently available and has been replaced by NOCO. Instead you could use a single bank charger like the NOCO Genius 12v 10amp # NOC44FR, which is the newer version with the same specs as the GEN1. In order to charge your 6v batteries wired in series you'll want to start by connecting the positive charging wire from the NOC44FR to the positive terminal of the first battery in the series; you'll then connect the...

  • Recommended Winch for my Trailer to Pull Logs on
    For pulling logs onto a trailer I recommend going with the Bulldog Winch Trailer Winch part # BDW10040 it is a 12,000 lb. winch that will get the job done for you. I've seen in the past when dragging logs they tend to dig into the ground creating extra force that needs to be overcome. This is of course if you're pulling really large logs. If you're dealing with smaller logs then a lighter winch would also do the trick. This winch also offers a wireless remote meaning that you will be able...

  • Can I Add the NOCO Genius On-Board Battery Charger to a System with an Existing Charger
    You can certainly install the NOCO Genius On-Board Battery Charger part # NOC44FR hooked directly to your battery bank while having the Progressive Dynamics Mighty Mini AC/DC Panel and Converter/Smart Charger part # PD4060K which is a direct replacement for the WF-8955PEC. It can be used apart from the on board changer by simply plugging it in and not the shore power cable of the camper. If you had your shore power hooked up I would not plug in the NOCO Charger. I would use one or the...
