NOCO GENIUS1 Smart Battery Charger Dimensions

The NOCO Genius 1-amp smart charger quickly charges and maintains your 6V and 12V lead-acid and lithium-ion batteries, and plugs directly into a standard household outlet. Rated for 6V and 12V batteries up to 30 amp-hours, it's a great charger for ATVs, wave runners, lawn mowers, and other equipment. It also is ideal for daily battery maintenance or long-term storage of cars, boats, trucks, and RVs. With 4 selectable battery profiles, multi-stage charging, and advanced safety features, this Genius smart charger makes it easy to keep your batteries in peak condition. There's even a Force Mode feature for charging dead batteries with 0-volts.

NOCO GENIUS1 Genius Battery Charger Operation

This Genius smart charger removes the frustration of having to own multiple devices to charge different battery types and vehicles. Just attach the battery clamps to the vehicle's battery terminals, select a charging mode to match your application, and wait for the LED indicator to signal that the battery is completely charged. It's that simple.

User-Friendly Interface with LED Indicators

NOCO GENIUS1 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 GENIUS1 Smart Diagnostics Troubleshooting Explained

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.

5 Battery Charging Modes

This Genius 1-amp smart charger has 5 selectable charging modes that let you quickly switch between charging different lead-acid and lithium-ion battery types at different voltages. Traditional battery chargers generally only work with a specific voltage or battery type, like lithium-ion or AGM batteries, or only in special circumstances like charging in cold environments. This Genius smart charger gives you the versatility to tackle different battery types and charging situations in one charger.

NOCO GENIUS1 Automatic Battery Charger Charging Modes Explained

The image above details the available charging profiles. The charger works with 6V and 12V wet cell, gel cell, enhanced flooded, calcium, maintenance-free, AGM, and 12V lithium-ion batteries with battery management systems (BMS).

NOCO GENIUS2 Force Mode for Charging Zero Voltage Batteries

The Genius 1-amp can detect and charge batteries that have been drained to 1-volt. And by activating the Force Mode, the charger can even charge dead batteries with 0-volts. Traditional chargers can't detect a battery when the voltage drops below a certain level. To activate Force Mode hold the mode button down for 5 seconds.

Genius Precision Battery Clamps

NOCO GENIUS1 Genius Precision Battery Clamps

The needle-nosed battery clamps included with this Genius smart charger are designed to easily connect to battery terminals of all shapes and sizes. Unlike typical, plastic battery clamps, these clamps are constructed entirely of metal, ensuring maximum conductivity. The clamps are covered with an over-molded plastic housing, which makes them easy to operate even with work gloves on. A built-in 2-amp fuse protects your connection against dangerous overloads.

NOCO GENIUS1 Battery Clamps with Eyelet Connectors

1/4" Eyelet connectors can be unbolted from the clamps for direct mounting to terminals on hard-to-reach batteries. The lie-flat design ensures maximum contact with terminals to optimize current transfer.

Quickly Charge and Maintain Batteries from 120VAC Power Source

NOCO GENIUS1 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.

NOCO GENIUS1 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 GENIUS1 Rugged Weatherproof Housing

The Genius smart charger comes with over-molded connection points to protect the unit from dirt, dust, and water. The unit has an IP60 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.

Interchangeable X-Connect Accessories

NOCO GENIUS1 X-Connect Accessories for Versatile Charging Solutions

This Genius smart charger features a unique X-Connect plug that lets you disconnect the battery clamps and attach other X-Connect accessories (all sold separately) for versatile plug-and-play charging solutions. Add an extension cord to increase your connections reach, or use the 12V female plug to connect and power 12V accessories. Access your vehicle's battery through charging ports with the OBDII connector, or the 12V male plug. With a large variety of available accessories this battery charger can be outfitted to meet your application's specific charging needs.

Video Transcript for Review of NOCO Battery Chargers - Battery Charger - 329-GENIUS1

Ellen: Hey everyone. I'm Ellen here at etrailer.com. And today we're taking a look at the NOCO battery charger and maintainer. so this is going to be a nice compact system to help keep the charge on your batteries. It's going to come with the clamps to go on your negative and positive side, and then that's going to connect to our charger here with those X connect cables to get everything ready to go. The nice thing about this is that anytime you're going out to use your equipment, your snowmobile, maybe a lawn mower, personal watercraft, any other kind of small vehicle and the battery's dead, you're kind of out of luck, but this is going to be able to work with those six volt batteries and also 12 volt batteries.

It also works for just about any kind of lead acid battery and also for lithium ion. So pretty versatile system.You don't have to worry about having a bunch of different cables and different chargers to charge each one of your items. You should be able to use this one system to get everything ready to go. To connect this together, we'll have our two little connectors here to plug in. All of the NOCO systems or all the NOCO products are going to have this connection or a lot of them do, so you can utilize each of these parts with other connectors and use the clamps for maybe a 12 volt battery charger or something that runs off of a 12 volt plug rather than having to use the wall adapter.

The only thing is that you wouldn't get to utilize that genius system here so you can kind of mix and match with other NOCO products. Of course, those other no NOCO products are sold separately. You can find a lot of them here at etrailer.com. But the thing that I like about this again is that it's going to be so compact and it can really bring our batteries back from the dead.So even if our batteries discharge all the way to zero volts, we can use the force mode to manually bring that battery back to life so you don't have to worry about your battery being low, especially in the winter months. A lot of times our batteries can start to deplete and you don't have as long a life out of them.

By having this on hand, you'll be able to maintain that charge and make sure that that battery is ready to go whenever you are. And I also like that it's compact enough that we can throw this in a drawer somewhere. We can keep it in a toolbox. Again, it wouldn't be necessarily the most versatile or the most mobile system since you do need to plug this into a wall socket or an AC power source, but if you have an adapter for a 12 volt plug to plug this into, you can utilize it that way as well.There are different modes that we can set using that button at the bottom, so you just press that to scroll through the different options for your battery setting. It also has a hybrid density technology, so that's how we're able to get that same efficiency out of this as you would see with other larger systems while still keeping a really small profile, this housing itself is going to be nice and durable.

It's IP65 rated, so that means that it's impervious to dust and water tested with jets for at a distance about three meters for about 30 minutes. That's usually the IP5 testing for that. So it should be up to the task. Even if you happen to get no rain storm or something like that. Of course, you never want to get this plug in a wet situation and same thing for those open terminals there.But the box itself should be rugged enough, has the overmolding on all the connectors and on the clamps themselves. So even if you're a little rough on this, it should last for a long time. The housing is lexan resin. That's just a brand named polycarbonate, which is known for being resistant to shock and impact and also for temperature. So it can still work down to negative four degrees fahrenheit and up to 140 degrees fahrenheit. So even if you're in some extreme weather conditions, you should still be able to utilize this and get everything charged up and ready to go.As far as the specs with this, again, it can work for it those 12 volt and six volt batteries, the battery types that are supported are wet cell, gel cell, enhanced flooded maintenance-free AGM and lithium ion batteries. As far as the size, it's going to be about four and 7/16th inch long by two and three quarter inch wide and one and 5/8th inch thick. The max amperage that we can get out of this is going to be one amp. The max power consumption is going to be 15 Watts. Our low voltage detection rating is going to go down to two volts. Again, that operating temperature goes between negative four degrees Fahrenheit up to 140, weighs just half a pound and has a three year limited warranty. Well, that's about going to do it for our look at the NOCO battery charger. I hope this video has been helpful and thanks for watching.

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. 779652

  • Simple Light Needed for Horse Trailer Tack Room
    The easiest thing to use/install is the NightMinder RV Task Light # NM-Motion-011. This is a battery powered light that uses 3 AAA batteries (not included). All you need to do is get rechargeable batteries to avoid purchasing batteries constantly. It would also be good to get at least 6 batteries so you can have some charging while the others are in use. Obviously if you want to use more than one of this light then you'll want to get the appropriate amount of batteries. If you'd like...
