NOCO GENIUS5 Smart Battery Charger Dimensions

The NOCO Genius 5-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 5 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 GENIUS5 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 GENIUS5 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 GENIUS5 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.


6 Battery Charging Modes

This Genius 5-amp smart charger has 6 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 GENIUS5 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 GENIUS5 Force Mode for Charging Zero Voltage Batteries

The Genius 5-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 GENIUS5 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 10-amp fuse protects your connection against dangerous overloads.


NOCO GENIUS5 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 GENIUS5 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 GENIUS5 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 GENIUS5 Rugged Weatherproof Housing

The Genius5 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 GENIUS5 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.

This is what GM recommended for my 2021 Chevy Colorado and it has worked just great. With the truck sitting sometimes two weeks I would have a problem with battery drain. Since purchasing the Noco Genius Smart Battery Charger from E Trailer, I have not had one issue with a low battery. Great Product! Donn't waste your money buying those cheap chargers.

Well spent money on this charger. Even after constant use over the last year I know I can count on it to keep my rechargeables charged. Great Product for a Great Price.



by:

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.



by:

First off this product is GREAT! I bought a few and returned them. This one I love. It REALLY WORKS. Also, etrailer is AMAZING! I have never used them before but going forward it will be 1 of the 1st sites I go look at. most of the time I am an [online retailer] guy but with shipping being 1 month out I looked elsewhere. etrailer even upgraded my shipping!!!! seriously, this was a GREAT experience and I will be a repeat customer.



by:

I now have 4 NOCO genius chargers. Easy to use for maintaining batteries!!



by:

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.

Installed these on my boat for an on-board battery charging setup to keep both batteries in top shape. etrailer had them shipped to me promptly and with excellent communications.



by:

The Noco battery charger has worked very well for storing my motorcycles over the winter. I like the option of keeping 2 batteries charged off one unit. However, motorcycle batteries typically use SAE connectors to the battery harness. The Noco only offers SAE adapters at an additional cost of $26 each. That means I spent 50% more to equip the charger to do the job I needed it to do. SAE adapters should be included as standard with the charger.



by:

The NOCO Genius Smart Battery Charger keeps my auto batteries fully charged without over charging when the vehicles aren't used often. Also, it keeps my non-used batteries (lawn mower, tractor, quads) fully charged during the winter months.

  • Can NOCO Genius Smart Battery Charger # 329-GENIUS5 be Left on Battery
    Yes you can leave the NOCO Genius Smart Battery Charger # 329-GENIUS5 attached to a battery long term as once the battery is fully topped off it will switch to a maintenance charge that will keep it topped off.

  • How To Charge Vehicle Battery Using Trailer Battery While Hooked Up To Shore Power
    The purpose of a diode is to stop the back flow of electricity. I can honestly say I have never heard of someone wanting to run a charge line from the trailer battery to the vehicle battery but I'm sure it would be possible. That said, when you attach two batteries to one another via a charge line they will try to balance each other. Therefore, if the start battery has more juice than the trailer battery the trailer battery will pull from the start battery and vice versa. The diode however...

  • Maintenance Charging Trailer Batteries Using An Isolation Solenoid
    Yes. The difference in battery styles doesn't matter for you to use the Battery Isolation Solenoid # PK5231201 to give you a maintenance charge on your trailer batteries while connected. When disconnected from your tow vehicle for long periods, I recommend using a battery tender/maintainer like the NOCO Genius Mini # 329-GENIUS5 versus a trickle charger on those batteries to make sure your trailer is ready for use when you are ready to camp. This unit uses a multi-stage charging algorithm...

  • Can NOCO Genius Battery Charger and Maintainer be Left Installed on Vehicle When Starting Vehicle
    You can leave the NOCO Genius Battery Charger and Maintainer # 329-GENIUS5 on your vehicle as it warms up. Doing so would not damage the vehicle battery or the charger. With the added amperage of your alternator on the battery the charger would simply stop charging.

  • Wiring 12 Volt Batteries for Same Voltage But Increased Amp Hour Usage
    When you wire your 12v batteries in parallel, the voltage stays the same but the capacity is doubled. This is regarding the amp hours you referenced. You can use the Deka Stackable Battery Cable - 2/0 Gauge - Black - 13" Long # DW04316 and Red # DW01485. The NOCO Genius Smart Batter Charger - AC to DC - 6V/12V - 5 Amp # 329-GENIUS5 you asked from is able to be used when two batteries are wired in parallel.

    The CTEK MULTI US 3300 12-Volt Universal Battery Charger w/ Pulse Maintenance # CTEK56353 is only a 12V charger that will allow you to connect the lead wires to the battery terminals with either spring clamps or ring terminals. For a charger that can charge both 12-volt and 6-volt batteries I would use the NOCO # 329-GENIUS5. If you are wanting to charge between the two batteries, that is not a directly compatible option. You could however charge two 6V batteries wired in series with...

  • How Long Does it Take for the Tekonsha Prodigy P3 Trailer Brake Controller to Drain a Battery
    If you completely disconnected power to the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 then you would indeed lose all of your settings. The controller does go into a sleep mode after around 15 minutes of inactivity but there will still be a few milliamps of power being draw from the vehicle's battery. This could then potentially drain the vehicle's battery after a few months but since the charging system on your 2001 Dodge Ram 2500 features a two battery bank, it might last...

    The Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D is designed to charge an auxilliary battery form the vehicle alternator output or from the starting battery on the vehicle. This charger would not work for your application unless you have a solar panel that can be ran to the yellow input wire of the # 331-BCDC1225D charger.

This relay is located in a fuse box under the hood, next to the vehicles battery.

  • Is Isolator Needed When Installing Battery On Trailer And Connecting To Tow Vehicle Wiring
    A diode or isolator is not necessary if you are installing a battery on your trailer in the same manner as was recommended on the earlier question. There would not be enough power flowing back to the towing vehicle that would cause damage. The battery charger I recommend is the NOCO Genius Mini # 329-GENIUS5 when you are near shore power. This has pulse maintenance to keep the battery charged so that it is ready to go when you are.

  • 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 Battery Charger Be Left Installed on Vehicle That Has Lights that Come On Occasionally
    The NOCO Genius Battery Charger and Maintainer # 329-GENIUS5 is essentially the same thing as a battery tender maintainer. This will charge a dead battery and then once it senses that it's fully charged goes into maintenance mode to keep it topped off. You'd be able to leave it hooked up and put small amounts of draw on the battery no problem. I have this charger on a car at my house and I open the door of the vehicle on occasion which turns on the interior light and it works just fine.

  • Electric Trailer Jack Light Comes On but Motor Does Not Run
    I do not think the fuse is blown because the light still comes on. It sounds like the motor has gone out. This could happen from over extending a jack or overloading it. If the jack is connected to a battery mounted on the trailer, the battery may not have enough juice to power on the motor but just the light. Take the battery off and have it tested. For a battery charger, use NOCO Genius Smart Batter Charger - AC to DC - 6V/12V - 5 Amp Item # 329-GENIUS5. This charger works much better...

  • Amount of Power Drawn By Optronics Platinum Burners Off-Road LED Lamps
    The Optronics # LS204RW Platinum Burners lamps draw about .3 amps while the # LS16A2WS (which we don't offer) draws about .5. A motorcycle battery would be a good balance between available power and reduced size and weight, and would provide the amount of power you'd need. If you don't already have one, you'll need a charger like # 329-GENIUS5 to keep the battery charged when not in use.

  • 12-Volt Accessory Circuit from Trailer Connector Not Keeping Trailer Battery Charged
    For starters, be aware that the limited wire gauge feeding this 12-volt circuit from the 7-way plus the distance the two batteries are away from each other means that although the tow vehicle battery can provide a maintenance charge to the trailer battery, it won't have sufficient power to charge it once it's discharged or nearly so.

  • Will Wiring Two 12V Batteries in Series Result in Double Capacity
    Wiring the batteries in series is going to give you double the voltage (24V) with the same capacity (Ah). In order to have the same 12V power with the additional Ah you will need to wire the batteries in parallel. This will give you the same voltage with double the capacity. See the diagrams below.

You will also need no drill mounting bracket # 18140 With that done you will need to replace the connector on your 2007 Little Guy tear camper with the # PK12706 to replace your 4-way connector, and more # 10-1-1 to run from the 7-way to the battery on your camper.

However, you will need to make sure the motorcycle battery is 12 VDC as some can also be 6 VDC which you could still use but would need to use two and wire them in series. Please note that the unit would still need to have access to 120 VAC as well as natural gas in order to function properly. The...
