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. |
| Question: | This charger comes with Intense Curl Cream? Where are the charger spec's |

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: | 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: | Will cutting and extending the battery cables void the warranty |
| Answer: | YES, anything you do to alter this charger will void the warranty! |
| Question: | my battery for my trolling motor seems to run low before I’m done fishing Would this work to give it a boost |
| Answer: | That depends on age of your battery and do you charge it before & after your fishing trips. Note: you said battery, does that mean you have one battery for trolling motor? If so why are you asking this question on a 3 bank charger (a 3 bank charger charges 3 batteries at the same time)? If your trolling motor battery is over 3 years old and after you charge it for 3 hrs, let it set for 3 hours and test the voltage of the battery with a good Volt meter. If the volt in the battery is less than 12.5 V, you need a new battery, charging will not make your battery last any longer while fishing. You need a good strong 12V Deep Cycle single charger battery for trolling motors (for sure with one battery). Good luck. |
| Question: | I purchased the 5/5 12volt is it normal for the charger to be really hot to the touch it is connected as directions |
| Answer: | I have the 5/5/5. When the batteries are low and charging the charger will get very warm. It should not burn your hand but it does need to have good ventilation. When I mounted my I installed stand offs so the unit can get as much air around it as possible. As the directions state, do not mount it directly to carpet or wood. |
| Question: | Will this charger (2720A) replace the Guest |
| Answer: | You have to know the specs on both ones. |
