Video Transcript for Review of NOCO Battery Chargers - Battery Charger - 329-GENIUS2D

Jeff: Hello everybody. This is Jeff at etrailer.com. Today we're going to take a look at this NOCO 12 volt, two amp AC to DC Genius smart battery charger and maintainer. Now this AC to DC smart charger will quickly charge and maintain a 12 volt battery. It's perfect for charging ATVs, wave runners, lawnmowers and other equipment. This is also great for daily battery maintenance or longterm storage of cars, boats, trucks, or RVs.

It does offer a multistage charging algorithm, which will charge two times faster than traditional chargers without overcharging. It does analyze the battery condition to provide a customized charge and it has a built-in battery desulfator to restore lost battery capacity.It is a very simple operation with the mode button and the LED indicators. The power button allows you to easily begin the charging cycle and then it has backlit LED indicators that'll let you verify that the unit is operating correctly and they allow it to be easily operated at night. These indicators signal units charged status and alerts you to potential performance issues or errors. It does offer an auto memory feature which will remember the last charge mode if power is lost.

The housing on this is a nice tough lexan resin. It protects the internal electronics and its impacts and it's water resistant.Over here it has the heavy duty 3/8" diameter eyelet connectors which will provide maximum contact with your battery terminals and it also includes this built-in 10 amp fuse to protect electronics from dangerous overloads. It does come with this nice snap-fit bracket that has a hook and loop strap to secure the unit near the battery. It has the mounting screws. Basically, you just pull the hook and loop and then you mount this to where you need it and then what'll happen is you just snaps right in place there, run your hook and loop through there.

Once you pull it through there, it'll go around the charger, then swing it back up there and it holds it into place. Wherever you mount this, it'll help hold this into place.Application again, this is for 12 volt batteries that are rated up to 40 amp hours. The battery types that this supports is the wet cell, the gel cell, the calcium and hands flooded, maintenance free and the AGM batteries. Maximum charging amperage is two amps. Maximum power consumption is 28 Watts.

Operating temperatures on negative four degrees to 104 degrees Fahrenheit. The islet cable link over here, if we pull it all the way out, is about 24 inches. The AC cord length that plugs into the outlet is about 24 inches. Weight of this is only about a half a pound.Last thing I want to do is just give you some dimensions on this. The length of this, if we measure from where this cord comes out and where that cord comes out, it's going to be right at five inches. Just the box itself, it's about three and a half inches. The width on it, it's going to be right at two and a half inches. The overall height on it is about one and a half inches tall, but that should do it for the review on the NOCO 12 volt, two amp AC to DC Genius smart battery charger and maintainer.

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.


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

Review from a similar NOCO Genius in Battery Charger


Having used THE NOCO Genius2 battery charger for greater than 1 years, I can say that I am completely satisfied with form and function of the device. I use the charger to maintain fresh battery charge for my RV trailer. I like the compact, portability and weight of the unit. The indicator lights keep me informed of the battery charge status. I consider this purchase as one of my best purchases of all my RV gear. Thanks for an excellent product.

Review from a similar NOCO Genius in Battery Charger


I like that it's weather proof and has selectable charging. It charges car batteries quickly, but I mostly use it to charge the chassis batteries in my motorhome while it's in storage. The only negative I've found is that it doesn't handle Arizona summers, but I haven't found a charger that does. I use it for a few hours early in the morning and that seems to be sufficient. I installed the NOCO eyelet terminal accessory on each set of batteries.



- 329-G1100
by:

Review from a similar NOCO Genius in Battery Charger


The Noco G1100 is one of four items I purchased from etrailer to make a portable 12 volt power pack for camping. I wanted to make my own power pack because many available do not have the power I want, have gimmicky features I do not want, and the batteries are not usually user-replaceable. Noco’s X-connect feature made this very easy. I also ordered a HM082BKS box for a U1 type battery, a GC010 12 volt female connector (cigarette lighter type), a GC013 male-to-male coupler, and a GC004 10 foot extension. From elsewhere I purchased a 35 amp/hour U1 battery with screw terminals (Interstate DCM0035) to fit in the box. I unscrewed the battery clamps from the charger output cable which left ring terminals I then attached directly to the battery. Leaving this part attached to the battery, the X-connect feature allows me to: (1) hook up the charger to the battery, or, (2) with the GC013 coupler, attach the female connector for camping. I expect to use this power pack for my CPAP, which can run directly from 12 volts DC (without an inverter), and eventually other items, such as a 12 volt TV. I can also power and charge USB devices with a USB adapter/charger which plugs into the 12 volt female connector. I’ll be testing the setup during an upcoming trip but have no reason to doubt it will work as expected. Of course, you could do the same thing with a bigger battery with the proper charger and battery box. The X-Connect feature is great and I should not have to open the box until I need to replace the battery. I have attached pictures which show (1) the charger attached to the battery, (2) 12 v female connector connected to the battery with the male coupler, and, (3) the unit ready for travel. The little dust cap from the X-Connect is attached to the battery box strap.

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.

Works as advertised. Quality product, simple operation. Especially like how the system remembers the last battery type setting for each of the 4 banks of chargers. I bought several more Noco chargers after this one.

Review from a similar NOCO Genius in Battery Charger


Not sure why they chose the name "Genius" since it turns out I had to do a fair bit of button pushing to set it to charge my 6v battery. It also runs very hot. Supposedly, however, it will remember that setting next time. Finally, The instructions are not only poorly written, they're printed in a very small font. I normally do not have to use a magnifying glass to read instructions. There's plenty of room in the elaborate packaging so I cannot understand why they couldn't have made it much bigger. Not sure this item was the best choice for maintaining my batteries.

Review from a similar NOCO Genius in Battery Charger


I have ordered a few products from etrailer and have been very satistfied with the products and customer service. The latest product I recieved was the NOCO Genius UltraSafe Battery Charger with JumpCharge Engine Start. As soon as I recieved it I hooked it up to my RV batteries to begin a trickle charge. Just looking at the features on the product it has a lot of capabilities. So far it is working great on the 12V cold battery charge. I am particularly happy with, and a little surprised, how quick etrailer responds to my questions, how helpful they have been, and how quickly I recieved all of the items I have ordered. I highly recommend checking out etrailer for any of your trailer needs.

very satisfied with this purchase. I had a GM battery at 81% on standby, it took just a few minutes to fully charge using this device. Now is on maintenance mode fully charged and ready to go.

Review from a similar NOCO Genius in Battery Charger


Because of great demands on marine batteries these days with electronics and trolling motors, it is important to maintain their voltages when not in use. The Noco Genius Smart Battery Charger-2 amp not only charges the battery back up but also maintains it so you are always ready to go. Built for marine conditions this little charger takes up miniumum space and is easy to use with nicely made gator clips and a long detachable cord making connecting time a snap. Bright LED lights let you know where this trickle charger is in the cycle and flashes a green light when done and in maintenance mode. The instruction booklet is helpful but use a magnifier to catch all the details in the fine print. Everyone needs this little device to keep 12 volt batteries fresh and ready to go and e-Trailer has one for your car or recreational need!

Review from a similar NOCO Genius in Battery Charger


First time owning a NOCO Genius charger, and I'm very happy with it. It's nice having alligator clips and eyelet connectors for charging. I use this to charge my second battery in my vehicle, as a supplement charge. I don't drive far enough for it to top off my the battery with the current dual battery charger. So I use this every couple weeks to do so. I also use this to top off my house battery in my trailer. It provides a fast charge time, no matter what battery I use. And I love how it has different options on the charger like 12v or 24v charge, AGM, repair, etc. I have a variety or batteries, so I don't need different chargers with one. Overall I'm very happy with it.

Review from a similar NOCO Genius in Battery Charger


I had a 2 year old 12amp 3 bank Noco on my boat before purchasing the larger size 30amp 3 bank charger. After removing the old charger and installing the new one and hooking everything up and powering. The new charger alerted me that one of my batteries had a error code. To make sure it wasn’t the charger I switched the banks and it still gave me a error code. In short...I took the old batteries back to where I bought them. I was in luck because the batteries would of been out of warranty in 4 days saving me $250.00 in replacing them out of warranty...So the new charger saved me the replacement cost so in hind sight this charger was free. Couldn’t be happier with this purchased. Thanks to Etrailer for the super fast delivery time!

Ask the Experts about this NOCO Battery Charger

  • 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.

  • 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...

    SInce it has a single wire, it is a clearance light. You will use the mounting bracket as your ground as you stated and run 12v power to the wire. 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...
