NOCO GENIUS10 Smart Battery Charger Dimensions

The NOCO Genius 10-amp smart charger quickly charges and maintains your 6V and 12V lead-acid and lithium-ion batteries, using a standard household outlet. Rated for 6V and 12V batteries up to 230 amp-hours, it's a great charger for cars, motorcycles, lawnmowers, ATVs, tractors, trucks, SUVs, and boats. With 7 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 GENIUS10 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 GENIUS10 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 GENIUS10 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.

8 Battery Charging Modes

This Genius 10-amp smart charger has 8 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 GENIUS10 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 lithium-ion batteries with baterry management systems (BMS). A 12V repair mode lets you restore lost capacity to sulfated and old batteries.

NOCO GENIUS10 Force Mode for Charging Zero Voltage Batteries

The Genius 10-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.

12V power supply mode lets you power a 12V accessory. This works great for powering accessories like a tire inflator around the home or garage.

Genius Precision Battery Clamps

NOCO GENIUS10 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 20-amp fuse protects your connection against dangerous overloads.

NOCO GENIUS10 Battery Clamps with Eyelet Connectors

Extra-large 13/32" 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 GENIUS10 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 GENIUS10 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 GENIUS10 Rugged Weatherproof Housing

The Genius10 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.

Interchangeable X-Connect Accessories

NOCO GENIUS10 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.

Review from a similar 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. 779652

The amount of time it will take to charge your battery is going to depend on how many amp hours your battery is rated for.

  • Battery Charger for a Trailer Battery on a Dump Trailer
    For your larger battery, I recommend the NOCO Genius Battery Charger and Maintainer # 329-GENIUS10. This charger is designed for larger batteries like the one on your trailer. The 12-volt accessory circuit on your 7-way trailer connector can be used to maintain a charged battery, but it won't have enough amperage to charge an almost completely discharged battery.

  • Can NOCO Genius Battery Charger and Maintainer # 329-GENIUS10 Be Left on Battery
    The NOCO Genius Battery Charger and Maintainer # 329-GENIUS10 that you referenced can be left on as long as you'd like it to be installed. It will lower the charging down to a maintenance level once the battery is full charged so that it doesn't end up over-charged. This type of maintenance charge will keep it topped off and very healthy for when you go to use it. This is compatible with Lithium batteries like what you have as well.

  • Can 12-Volt Battery Charger Charge Two 6-Volt Batteries Wired in Series
    Being able to charge batteries wired in series isn't CTEK's strong suit. The # CTEK56353 charger will read the output as 12 volts, and could consider the batteries fully charged but it's possible they wouldn't be balanced. In this instance, CTEK recommends using a charger for 6V batteries, like part # CTEK56191 to charge the batteries individually. The batteries should be disconnected from each other for charging. The NOCO chargers however, like # 329-GENIUS10 is capable of charging...

  • Do Both Wires on ETBC7 Need to be Installed on 2018 Jeep Compass if Trailer Doesn't Have Brakes
    You are correct. If you don't have brakes on your trailer then you can just use the Universal Wiring Kit # ETBC7 as an adapter and then only connect the 12V power to the battery on your 2018 Jeep Compass to help maintain your battery level. I do recommend routing the brake controller wire from the 7-Way at least up to the engine compartment though since this is duplex wiring. This will make it easier to install a brake controller if you need to do so in the future. To keep your trailer...

  • Can Two 12 Volt Batteries Connected in Parallel be Charged Through a Switch Using a NOCO Charger
    You can charge 2 batteries when they are connected in parallel using a battery charger such as # 329-GENIUS5. However, it will take longer to charge the batteries when they are connected compared to if you were to charge each one separately. The best battery charger to use for charging batteries in parallel would be # 329-GENIUS10. It has a higher amperage output and will charge faster. I have included a link to our FAQ article on battery chargers for you.

  • Can 12V Feed from Vehicle 7-Way Overcharge Trailer Battery
    You don't need to install any other parts in line with your 12V trailer battery line. Because the current being sent through the 7 pin power wire is so low, it acts more like a trickle charge to simply keep your battery topped off. It is not powerful enough to actually provide a full charge to your trailer battery, so it couldn't overcharge it even during a long trip. The Breakaway Kit Battery Charger # 20011 is used to prevent overcharging the smaller battery in a breakaway kit, like...

  • Trailer wiring
    If you use an adapter like # 37185, and the black wire is extended and ran to the positive battery terminal through a # 9510 40A circuit breaker using # 10-1-1 wire, the battery on the trailer will receive a maintenance charge. However, due to the relatively small gauge of the wire and the distance between the battery and alternator an the trailer battery means that the system won't have the necessary power to charge a depleted battery. You'll still need a charger like # 329-GENIUS10 and...
