User-Friendly Interface with LED Indicators

NOCO GENIUS2D LED Charging Indicators

This Genius smart charger was designed to provide a simple, user-friendly experience. The power button allows you to easily begin the charging cycle. 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 and alert you to potential performance issues or errors.


NOCO GENIUS2D Smart Diagnostics Troubleshooting Explained

This allows you to identify if the battery voltage is too high or too low for your selected mode, or detect a reversed polarity connection to a battery.


Quickly Charge and Maintain Batteries from 120VAC Power Source

NOCO GENIUS2D AC Plug for Wall Outlet Charging

This Genius smart charger plugs into an available wall outlet to quickly charge and maintain your battery. 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. The included mounting bracket with hook-and-loop strap lets you mount the unit in an enclosed compartment, garage, or workspace.


NOCO GENIUS2D Charging Times for Battery Sizes

The table above provides a quick reference for how long it will take the unit to charge some different battery sizes.


Rugged Weatherproof Design

NOCO GENIUS2D Rugged Weatherproof Housing

The Genius2D smart charger comes with over-molded connection points to protect the unit from dirt, dust, and water. The unit has an IP65 rating, meaning the housing is considered "dust tight" and protected against water sprayed from a nozzle. A durable X-connect plug ensures a weathertight connection when attaching the clamps to the charger.


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

Review from a similar NOCO Genius in Battery Charger


For over a year now this little NOCO charger has kept the starting battery ready to go on our diesel backup generator. Before the NOCO we had to jump start it almost every time.

Works as advertised. Have used it to restore a 12v lithium 100ah battery which was allowed to go well below the recommended level of discharge. The compact size is also a big plus.

Review from a similar NOCO Genius in Battery Charger


Contacted etrailer.com about charging K2 Energy Lithium Ion marine batteries. They took the time to contact NOCO Genius chargers to get me the correct answers. NOCO said absolutely that this would be the correct charger for lithium ion marine batteries.

I am now confident that my investment of Lithium batteries will get the correct charge they require. The NOCO genius charger is lighter and smaller than my previous charger allowing more room and less weight in my boat.

Review from a similar NOCO Genius in Battery Charger


pretty expensive for a trickle charger, BUT it appears to be made from better than average materials, and it is compatible with wet cell, AGM, and even Li-ion. The battery clamps are really nice-looking, quality constructed, top grade material. It appears to me to be a really top shelf, state of the art, highly-optioned, trickle charger. 3yr warranty.

it has been working pretty much 247. Still working as advertised.

Very good quality, this is the fourth one I own, highly recommended

Good,but it does boil off battery fluid on my Yuasa battery. I have the charger on a timer to operate once a week for 3 hours to keep the batteries topped up, without fluid loss.

Review from a similar NOCO Genius in Battery Charger


We have had this charger for about a year now. We use it to recharge batteries for the camper and boat, and maintain them over the off season. It has worked great to charge both our conventional wet cell and AGM 12 volt batteries. It charges the batteries in a reasonable amount of time and, due to the "smart" multi-stage charging technology built into the charger, we do not have to worry about over charging the batteries. I highly recommend this charger.

Review from a similar NOCO Genius in Battery Charger


Wow! Your delivery and tracking system is excellent, very personal and accurate. My new battery charger is here and currently (yes pun intended) in use on my RV.

Review from a similar NOCO Genius in Battery Charger


simple to use, relatively fast charging. Particularly like that it has both alligator clamps and ring terminals. "Intelligent" charge controller quickly charges a dead battery but also dials back to trickle charges then off when full for better battery life (and less evaporation on non-sealed batteries) so you can leave the battery attached for optimum over winter storage.

  • Smart Battery Charger for Keeping Two 6V Batteries Charged While in Storage
    You will not have any issues using the NOCO Genius Smart Battery Charger item # 329-GENIUS2D to keep your Airstream batteries topped off in storage. I haven't heard of any of the issues you are describing. The Genius smart charger has LED indicators that will alert you of any issues with your batteries that would cause the charger to not function correctly. Since you are charging two 6v batteries I recommend using the NOCO Genius Smart Battery Charger item # 329-GENIUS2. This system is...

  • Can Powerhouse TC2 2-Amp Trickle Charger Be Used for 12V Car/Camper Battery
    The NOCO Genius Smart Battery Charger # 329-GENIUS2D is suitable for 12V batteries rated up to 40 amp-hours so if the 12V battery on your camper is rated for 40 amp-hours or less, you can use it. However, most standard sized 12V batteries are going to be rated for higher than that. This particular charger has a maximum output of just 2 amps so it's going to take a really long time (if ever) to charge up a full size 12V battery if it's anything less than fully charged when hooking it up....

  • Would Dead Breakaway Battery Throw Code for OEM Brake Controller on 2018 Chevy Silverado
    I don't think a dead breakaway battery would cause an error message to pop up, but that is something that would need to be addressed anyways with a charger like the NOCO Genius Smart Battery Charger - AC to DC - 12V - 2 Amp # 329-GENIUS2D or by replacing the entire breakaway kit (see attached link). Once the battery is charged up or you have replaced it that will let you know if the dead battery was for some reason throwing a code or not. If you are stilling having that code pop up then...

  • Can NOCO Genius Smart Battery Charger # 329-GENIUS2D be Used with Dual Outlet Adapter
    The NOCO Genius Smart Battery Charger # 329-GENIUS2D that you referenced is designed to plug into an AC outlet and give you a way to charge batteries. If you had it plugged into the NOCO AC Port Plug with Dual Extension Cords # 329-GCP2 at same time you'd be able to use same power outlet to power the accessories you mentioned as well as still use the charger.

  • Recommended Battery Charger for Harley Davidson Softail Heritage
    Greetings, If you were looking for something that would work great to keep your Harley's battery topped off while being stored over the winter the Noco Genius part # 329-GENIUS2D is the best option as it's a 2 amp charger that's priced really great and will work well for that purpose. If you were looking for something with a higher amperage rating that will charge a dead battery quicker and can maintain a charged battery through storage the part # 329-GENIUS10 is the best option.

  • Recommended Battery Wall Charger for Two 6V Batteries on RV
    You could technically use the NOCO Genius Smart Battery Charger # 329-GENIUS2D for the battery bank on your RV but I recommend using a 2-bank charger like the NOCO Genius Multi-Bank # NOC24FR instead. Reason being that sometimes more cost-effective chargers like this can get tricked into thinking the battery bank is in a good place when that first battery reaches full charge. With the 2-bank setup you will be charging the batteries separately so you know they will each be getting the best...

  • How to Activate Reverse Lockout on Boat Trailer When Moving it By Hand with a Tow Dolly
    It sounds like you're just needing to activate the reverse light function on a standard 5-Way connector so your boat trailer actuator will use the lockout for you to move the trailer around by hand with your dolly. I don't know of any handheld 12V power sources but you should be able to use a small battery like what you find with a breakaway kit # 50-85-313 and then wire the power only to the last pin on a 5-Way like part # HM47910 to send power to the lockout function on your actuator.

You can use a 12v marine battery connecting the negative to the bracket and the positive to the wire. If you want to install a switch like # PK34513 in line that will work well. You can use wire like the 14 Gauge Primary Wire - Yellow - per Foot # DW02412-1. If you want a converter, you can use the # 329-GENIUS2D to connect to a standard...
