NOCO GENPRO10X3 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 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.


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 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.

I received my noco 4 bank charger very quickly and is an amazing charger for my boat, etrailer had the best price around and they were very helpful in this purchase, only bad thing is I didn’t get the serial number to register the warranty before I mounted, thx etrailer.

this is the ultimate unit for onboard charger installation on dump trailers with dual batteries



by:

This was my first order with etrailer. Price was competitive and delivery was quick. I installed the unit and everything seems to be in working order. I am hoping for years of trouble free service. I did have a few online questions and they were answered in a reasonable amount of time

Great company, fast shipping

I've only had it installed for a few weeks so far but it has worked like a charm so far. I have 1 lithium and 3 lead acid battery's and being able to charge them all at the same time is very convenient. Batteries have been ready to go for all day fishing every time I've been out



by:

It appears to be a good charger. It is supposed to be compatible with the new lithium battery’s.



by:

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.

etrailer is a trusted vendor with great service, good pricing and product availability.

See what our Experts say about this NOCO Battery Charger

  • 7-Way Trailer Connector on a 2005 Chevy Silverado is Not Charging the Trailer Battery
    First, the wiring on a trailer connector is too small to charge up a battery on a trailer. It can only keep the battery at whatever charge level the battery is at. But if the connector is not showing power on the 12 volt circuit on the vehicle 7-Way (1:00 position if looking at the face of the connector) then there is a common cause. To test this circuit, use a circuit tester like # PTW2979 if you do not already have one. From 1999 to 2006 GM may or may not have made all the connections...

  • Can Charge Leads of NOCO GENPRO On-Board Battery Charger # NOC74FR be Used to Power Circuits
    Yes, the three leads of the NOCO GENPRO On-Board Battery Charger # NOC74FR that you referenced could be used to power the circuits you mentioned. As long as the voltage and amperage requirements match you'd be totally fine.

  • Can You Double Up Battery Leads on the NOCO GENPRO 10x3 On-Board Battery Charger
    I do have an option for you but doubling up on battery leads with the NOCO GENPRO On-Board Battery Charger part # NOC74FR won't increase the charge rate. The only way to do this would be with a higher rated battery charger, the NOCO GeniusPro Smart Battery Charger part # NOC37FR which has a 25 amp charging rate, 2.5x what you have currently so it will charge the battery much faster. For example, a 100 amp hour battery takes around 7 hours to charge from dead with the Pro10 and only 3 hours...

  • Can Charge Wires of NOCO GENPRO On-Board Battery Charger # NOC74FR be Extended
    While there isn't an extension harness made specifically for the NOCO Genius 10x3 part # NOC74FR it is possible to extend the wiring. You would just need to splice in the amount of extra wire you would need. I would go with a heavier gauge like with 12 gauge part # 12-1-1 which we sell by the foot.

  • Can You Connect The NOCO GENPRO Battery Charger To Multiple Batteries in Parallel?
    The NOCO GENPRO On-Board Battery Charger # NOC74FR can charge up to 3 different battery banks. It cannot connect to different batteries in a parallel or series bank of batteries. By connecting to one of the batteries in your parallel bank it will charge all of the batteries at once. If you had it connected to multiple batteries in the same bank it will not charge correctly as it will misinterpret the charge it sees as battery voltage.

  • Best Way to Charge 3 AGM Batteries on Boat
    The method you mentioned, using the 3-Bank NOCO GENPRO On-Board Battery Charger # NOC74FR for your 3 batteries, is the best way. And it sounds like that's what the other answer page stated, if I read what you said correctly. Technically you can charge a bank of batteries with a single charger but it's best to have each battery charging on it's own with wall chargers so that you know you get the best reading and charge for each battery. Sometimes if you charge a handful of batteries with...
