NOCO GENM2 Mini On-Board Marine Battery Charger Diagram

The rugged NOCO Genius GENM2 mini on-board smart charger quickly charges and maintains up to (2) 12-volt lead-acid batteries, simultaneously. Multiple battery banks efficiently charge deep cycle and starter batteries up to 120 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, the GENM2 was built to handle harsh marine environments, while keeping your batteries in peak condition.


Multi-Stage Smart Charging Technology

The NOCO GENM2 smart charger uses an 8-stage charging cycle to quickly and efficiently charge your battery. This ensures that the battery safely reaches maximum capacity without being overcharged.


NOCO GENM2 Genius 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 that the battery's condition is stable, it will initialize the charging process by providing a constant, gentle charge. The charger gradually increases the charge during the bulk stage and quickly charges the battery to 80-percent capacity.


As the battery nears full charge, the GENM2 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 GENM2 Heavy-Duty Eyelets

2 Sets of 3/8" eyelets connect the GENM2 to your batteries. Over-molded connection points stand up to heavy usage and keep connections safe from the elements. Built-in 15-amp fuses protect each connection against dangerous overcurrent.


Quickly Charge and Maintain Batteries from 120VAC Power Source

NOCO GENM2 AC Plug for Wall Outlet Charging

The GENM2 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.


Rugged Submersible Design

NOCO GENM2 Waterproof and Ignition Proof Design

The GENM2 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 GENM2 GCP AC Port Accessory

Available AC port plugs (sold separately) from NOCO let you easily setup your GENM2 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.

  • Would NOCO Genius Mini On-Board Battery Charger # 329-GENM2 be Able to Charge 80 amp Hour Battery
    The NOCO Genius Mini On-Board Battery Charger # 329-GENM2 has the amperage to charge batteries with up to a 120 amp hour rating so your that is rated for 80 amp hours should not be an issue at all. If the battery was totally dead it should have still charged it by now so I'd be inclined to believe your battery might have a problem. I would recommend taking the battery to a car parts shop that has a battery tester to see if they can test it. Typically they have a tester they can throw...

  • Can Blue Ox Patriot Supplemental Braking System be Charged with AC Power
    Since the Blue Ox Patriot part # BRK2016 is designed for use in a vehicle it's charging system requires 12 volts of power and would not charge if connected directly to an AC power source like you described. You'd need an adapter to convert the AC power to DC like the NOCO Genius Mini On-Board Battery Charger # 329-GENM2 and you'd be able to charge the Patriot in your house.
