Battery Maintenance: Some marine battery chargers also offer battery maintenance features like desulfation and equalization.These functions help prolong the life of the battery by preventing sulfation buildup and ensuring that all battery cells are charged evenly.
Water Resistance: Marine battery chargers are typically designed to withstand the harsh marine environment. They often have water-resistant or waterproof enclosures to protect against splashes and moisture.
Multiple Outputs: Some larger marine battery chargers have multiple charging outputs, allowing you to charge and maintain multiple batteries simultaneously. This is useful for boats with multiple battery banks, such as one for starting and another for house systems.
Size and Capacity: Marine battery chargers come in various sizes and capacities to suit different boat sizes and battery bank configurations. It's essential to choose a charger that matches your specific needs.
Safety Features: Many marine battery chargers incorporate safety features like reverse polarity protection, short-circuit protection, and thermal overload protection to prevent damage to the charger or the battery.
Display and Monitoring: Some models include digital displays that show the charging status and battery condition, providing valuable information to boat owners.
Mounting Options: Marine battery chargers can be mounted in various locations on a boat, such as on a bulkhead or in an engine compartment, depending on their size and design.
Properly maintaining your boat's batteries is crucial for the safe and reliable operation of your vessel. Choosing a high-quality marine battery charger that matches your battery type and capacity requirements is an important step in ensuring that your batteries are always ready for use when you're out on the water.

User questions & answers
| Question: | Does this charger come with qiuck disconnect plugs on the positive and negative terminals |
| Answer: | No, the charging cables are bolted directly to the battery terminals - you would have to modify your installation for quick disconnection |
| Question: | how long are the supplied battery wires for this unit |
| Answer: | Supplied with prewired 6' cables for 2 batteries. Factory extensions are available separately. |
| Question: | Mine did not come with a terminal that connects to a battery. Am I supposed to buy an adaptor for it |
| Answer: | I am in the process of returning the one i got. the model number was 43012m21, not just 43012. I contacted ProMariner and they told me that i was sent a custom model that had some female plugs on them without any adapters. I am a little annoyed because i paid more for this one than another link on amazon because this was in stock. I almost cut the cords and put on my own connectors but i felt that buying a new item i should not have to do this. you can buy the male adapters for the connectors but you would probably be paying about 15 to 20 dollars for making your own cables. amazon should be sending me the correct model currently but im hoping they dont just send me another custom model. hope this helps other people because it took some work to figure this one out. |

User questions & answers
| Question: | I have the gen 4 when the lights show green it's still showing 14.56 volts is that normal |
| Answer: | Yes |
| Question: | Can I juse the NOCO GENIUS GENM2 charger with a Honda EU2000i Portable Inverter Generator |
| Answer: | Yes. That generator has a 120v outlet just like a house. I think the outlet is good for 20amps. Only thing would be you would need to run it long enough to power the charger so it could charge the battery it's hooked to which could take a while to properly charge. |
| Question: | Will this charge 6volt deep cycle golfcart batteries |
| Answer: | No Sir-This is only for 12 volt batteries-The model you want is the. Genius G3500 it will charge 6/12 volt batteries @ 3.5amp for around 50 bucks it will bring that battery back to life. |
| Question: | How dose it mount to the hull/boat...i dont see tabs for mounting screws |
| Answer: | On the corners are holes - drill those out and then use 6" lag bolts (as mentioned in another answer), or drill some holes in the hull and run zip ties. Larger holes make running zip ties easier. Note: while adding the holes in the hull will cause leaks, this unit is waterproof to 3 meters so it will work as your boat is taking on water. But it will be mounted well. |

User questions & answers
| Question: | What is the difference between the sc1280, sc1281, sc1323 and sc |
| Answer: | The length of warranty on paper doesn’t matter because getting them to act on it is difficult. They wanted me to send the charger to them at my cost and wait without a charger for 6?weeks |
| Question: | Can this be used to charge lawn tractor batteries |
| Answer: | Yes, they are plastic. And Yes the break. My negative terminal just snapped in half... Not happy. Why couldn’t they just use metal?? |
| Question: | What is the warranty on this product |
| Answer: | It will work with any brand of battery. |
| Question: | Want to charge battery in vehical (suv). is it safe to do in enclosed garage? thinking yes, but please confirm |
| Answer: | The clamps are metal on the inside (obviously), and a durable plastic on the outside as insulating covers. Looks to be pretty durable, I've had no problems with them. But then, I tend to take care of my toys! :-) This unit, by the way, was an excellent investment...after having owned several less-capable chargers. This one restored my Yellow Top battery back to its full capacity in short order! I own a Tahoe Hybrid and had installed the Yellow Top as a result of standard batteries not holding a full charge after a year or two, and often draining when not running the Tahoe at least once every 4-5 days or so. Can connect full-time to the battery the accompanying cable, making the use of clamps unnecessary! Just have to remember to unplug it! |

User questions & answers
| Question: | engine start and one thee battery house set ...so i need a 5 bank charger |
| Answer: | Your description is not 100%, but it sounds like you need three Banks. One for each starting battery, and one for your group of house batteries, assuming they are all tied together. |
| Question: | I am installing this into my sailboat. What is the 110v amperage draw |
| Answer: | The power consumed by any electric unit is equal to the Operating voltage V times the current I. or Power = V*I in watts. If this charger is charging 2 batteries at 12 volts each and drawing 10 amps for each battery the power used is 12 * 10 = 120 watts each. So the ideal power used would be 240 watts for the two batteries. The AC source must supply power in the same way so you need 110 volts times I amps = 240 watts. Therefore the current, I, drawn would be 240/110 or around 2.2 amps , but you never have ideal energy exchanges because of heat loss and other things. So I would think you would need to have a source that could provide at least 5 amps @ 110 volts or around 600 watts at maximum usage. Much less current is needed for trickle charging.This gives you a margin of error of over 200% so should be OK. Hope this helps |
| Question: | I have a single starting battery (one bank) .Then I have two deep cycle batteries in parrallel (bank 2). Do I need a 2 or 3 bank charger |
| Answer: | you failed to give the the voltage, type, and size of batteries, and what they are being used for, but going with the information you submited. providing all of the batteries are 12v d.c. you require a 2 bank charger, but if i were you, i would order the 3 bank charger for future battery expansion, i would connect one of the charger outputs across the neg & positive terminal of the stand alone 12v dc battery, and i would then connect the second charger output lead across the 12 v dc neg & positive terminal of one of the 2 batteries which are tied in parallel. the charger in question permits the 3rd charger output to be connected to the 3rd neg & positive post of the 3 rd 12 v dc battery which is tied in parallel. but if i were you, i would first contact the manufacture reps, before you do anything, tell them your set up, and see what they think. in any event good luck, and above all do not forget to ware the proper safty equiptment prior to doing any work on any batteries. |
| Question: | Does this unit have a cooling fan? Does it overheat |
| Answer: | No fan. Yes it over heats. Mine died after a month and MFG service and support link, nor the registration lik work on their website. Unable to get through via phone. Had to buy a new one. I went with Charles Marine charger. Superb charger. Beware of this one. |

User questions & answers
| Question: | What gauge wire is used on the leads? I'd like to cut the circle connectors off and leave about 2 ft but add a plug |
| Answer: | Received this in an email form NOCO regarding Genius Gen2 on-board charger: "The DC leads are 14AWG, and can be extended up to an additional 10' without modifying or moving the fuse. The fuse must remain in place and the additional length must be added after the fuse. Absolutely no AC modifications allowed. The warranty will remain intact as long as these guidelines are followed. We do not provide information on extending the cables so you will have to research the appropriate cable and connections yourself. An additional fuse may be added closer to the battery for additional safety." |
| Question: | Does this pair well with optimum batteries |
| Answer: | I have a different model but I am sure these work with all type batteries |
| Question: | What is the maximum charging voltage on these NOCO chargers? I want to keep it under 15V if possible for my AGM batteries |
| Answer: | It is a 12volt system, I have never seen it exceed it by more than 0.5 volts on my meter. This question is best addressed with the manufacture if you are extremely concerend. The amperage is what is going to vary the most with the discharge of your battery or batteries. I have had it for two (2) years and I am very happy with it, so much that i replaced the one in my travel trailer with a single NOCO and it works wonderful with my 12 volt lighting and fans. |
| Question: | Both my batteries can sit for for days at 13.3 volts (while off the charger) then i plug them in and red lights are on for two days? batteries are new |
| Answer: | If they are at 13.3 volts, they don’t need to be charged |
