Noco Genius Genm2 8 Amp 2-bank Waterproof Smart On-board Battery Charger (Auto Accessory) 1797

Review for genius amp waterproof smart onboard

Price was $99.95. Received item fast and was exactly as advertised. I read a lot of reviews which helped me with this purchase. I do agree with some of the reviews is that the power cord is a little short, but really no problem or issue for my application. If you are looking for an on board charger, this is it. Price is best by far. Great product.

Installation is straight forward and easy. Each bank has a negative and positive wire and there is a three prong 110volt plug for ac connection. The unit is totally sealed so being in the engine room and getting splashed from wash down is not a problem. A screw on each corner makes mounting easy. Hooked it up to two new starting batteries np200 and one used generator/house deep cycle battery. The indicator lights showed red and after two hours the starting batteries showed green and tested at 14. 68 volts. When i checked the house battery the next day the indicator light on the charger had gone green. It is slightly warm to the touch. When i use the boat without the generator running and i return to the slip, on plugging in shore power the indicator light will be red and go green after an hour or so. The unit makes no noise and does not affect the onboard electronics. My generator does not have an alternator so the charger supplies voltage to the batteries. I have had no problems with the unit and i have been keeping an eye on it just because it is new, which is super easy because all you have to do is glance at it and you get the status of each bank.

Noco genius genm2 8 amp 2-bank waterproof smart on-board battery charger Review (genm2)

I'm using this to charge six 6v deep-cycle batteries in a duffy electric boat. Each 12v charger circuit charges two of the batteries. Spoke with the tech rep before the purchase who was very helpful and explained that this application was perfectly ok for this charger. After three weeks it's working great - the bank is fully charged 100% of the time. I just purchased another one to charge the second bank, as both old chargers had failed about the same time. I'm hopeful that the noco ones will last many years. So far so good. -I. Laura

Now when i come home all i have to do is plug it into the wall. You keep it plugged in at all times and it keeps a trickle charge on the batteries to keep them in great condition. I love this charger. Well worth the $100. When you have a battery that costs $200 it is well worth taking care of."

Optima Batteries 8016-103 D34m Bluetop Starting Deep Cycle Marine Battery (8016103) FAQ.

Purchased 3 from online store very well packaged and fast shipping i needed these to replace 3 other optima for my trolling motor. The old ones were from 2007. 9 years of hard marine service and vibration. 1 of the 3 old ones went bad but you dont ever want to mix old optimas with new. So i replaced all three. The old batteries were also made in mexico so that made no difference to me. With optima batteries make sure you use a quality onboard charger and they will last for years and years. No they are not cheap but quality never is. I have 5 total in the boat, all optimas 2 for main engine 3 trolling motor batteries. Other 2 for main engine still going strong from 2005 -Notice from L.

I bought this battery to use in my starcraft trailer. I have only used in on one camping trip so perhaps a review is a little premature however, it worked great. The price and online store was the best and it came nicely packaged. I ran the lights and the heater on the battery for a whole weekend and it seemed like it had plenty of juice left. The gauge on my trailer showed the battery was at like 80% at the end of the weekend. So far i am pretty happy with this battery.

- Z. NancyI bought two of these batteries for my 24vdc trolling motor, not sure if i bought a great trolling motor or if these batteries just make it work really good. I have a 26' triton with a minn kota powerdrive v2 trolling motor and i can go two full days and still have juice left over. Whenever i replace a battery in my cars trucks or boats i replace them with an optima battery, i've always had good performance with them.

We took this camping for a week and used a power inverter to hook up a box fan and phone chargers. The battery never went out, not even close, and we were able to stay cool while camping - happy wife happy life! we were even able to leave it outside the tent and let it get rained on (marine battery), and i didn't have to worry about it spilling in the car on our 13 hour drive (spill-proof). This battery is tough, useful, and well worth the investment. I can't speak to the longevity, but i bought it because my friend has been using it and recharging it for 5 years and his is still going strong.

The F.A.Q. for noco genius genm2 8 amp 2-bank waterproof smart on-board battery charger

After 10 years the oem dualpro charger in my bass boat finally gave up the ghost. I needed to replace it and i did a lot of shopping in person and online looking for a replacement. Based on the longevity and reliability of my dualpro i was seriously considering investing in another dualpro - but they are high quality units and carry a price premium that reflects that quality and brand name recognition. . I spent the better part of two weeks trying to decide and pushed myself right up to the wall of my next fishing tournament trying to decide between the various makes and models out there. . Ultimately i settled on the noco genius gen2 based on favorable reviews here at online store and a couple other online forums. The price fit into an otherwise tight budget and unplanned repair expense, and i liked the fact that it was manufactured here in the united states. Cost and country of origin were my primary purchasing decisions. . Considering the installation spot, installation wasn't too bad. The unit isn't overly heavy and the closed mounting holes made it easier to get a screw held into place and started before tightening them down. Both the ac cord and charging cables are long enough to work with most any bass boat installation. Of course i clipped the ac cord plug and attached the ac wires to the replacement on-board charger inlet (that i also purchased from online store). . The first charge cycle after a recent fishing tournament went without issue, and both trolling batteries were fully charged by the next morning. If i had two complaints it would be the gage of the charging wires (much smaller gage than used by dualpro) and also the warranty terms. Make sure you read them over at nocos website. Their warranty is prorated after the first 1. 5 years, so in reality you don't get a full 3-year warranty. On the genius gen2 after 1. 5 years (with a receipt) warranty service will run you $44. 95. Should you miss-place your purchase receipt warranty service will run you $65. 95 anytime during the 3 year warranty period. . I reserved one star out of a possible five star rating to see how durable and reliable this charger will be moving forward. In my particular application - tournament bass fishing - it will see it's fair share of use in various weather, temperature and water conditions. Hopefully it will be up to the task.

A number of questions have been asked here.


(0) Question: where is the charger getting power from does it have to be plugged in?

(1) Question: will leaving a battery connected without ac power running damage the charger?

(2) Question: can the gen 1 10 amp charger be left permanently attached to a marine battery even when the battery is in use and being charged by an alternator?

(3) Question: there was no warrenty info sent with the noco 4 amp onboard charger, contacted noco 'no response'.

(4) Question: can all 4 batterys be chaged if thay are still hooked up together.

(5) Question: i have 4 xs xp750-ck batteries 12v agm battery max amps 750a ah: 22 rc: 28 will the noco genius gen4 40 amp 4-bank charger be to much? it says they ar

(6) Question: i would be using this with two marine deep cycle batteries to power a 68lb thrust 24 volt trolling motor. would you suggest the 2 bank 8amp or 20amp?

(7) Question: what is the maximum charging voltage on these noco chargers? i want to keep it under 15v if possible for my agm batteries.

(8) Question: can i juse the noco genius genm2 charger with a honda eu2000i portable inverter generator?

(9) Question: can i use the gen2 as a battery tender to trickle charge an suv that sits idle most of the winter?

(note) Question: where/how to get Noco (manufacturer's brand) accessories & similiar Noco's products

If you have a need for a charger to charge (4) 12v batteries in series, this is the one. I did exhaustive research before buying 5 of these. This one has it all! does what they say it will do. We are using these to charge storm siren batteries and they will not evaporate the electrolyte due to excessive gassing.

This is a replacment charger for me. I purchased a noco charger in the past and it failed after one year, noco. (online store) replaced it free of charge and sent a return label for the failed unit. I have installed the new unit, it seems to be operating well and hope it stays that way. Online store stood behind the product and made the replacement and return process very easy. Thank you!

W. Garner, Devon says

I spent quite a bit of time looking for a substantial charger (not a battery maintainer) that could be left connected to a battery continuously without overcharging. This unit fits the bill to a tee. It's almost too simple really. There is nothing to select: no knobs, no switches, just a couple of indicator lights to tell you what the charger is doing and any abnormal barrery condition. . This unit is completely sealed-it's designed to be used in marine service-and the battery cables are not clamps but rather permanent ring connectors designed to be fastened to the battery terminals. I am using it on a 12 volt deep discharge battery of 200 a-hr capacity, and this unit is designed for batteries up to just about this size (and smaller, of course). . Power interruptions don't confuse this unit and it just picks up where it was before the power was interrupted. . I used this to replace a conventional 10 amp charger that couldn't be left unattended safely without the danger of overcharging a battery. Very happy.

M. Olga, Sachsen

Some reviews were less than positive on this charger/maintainer but after installing and charging the battery on my 26ft sailboat, i am really pleased. The charger is completely encased and appears waterproof as claimed. Installation is 4 wood screws (provided). Done, plug it in and away it goes. It has safety features for reverse charging, etc. That are useful. Directions do warn against mounting above battery, but i suggest a purchaser use common sense. Most batteries are sealed, in a reasonably vented space. The unit is also sealed. The terminals that connect to the battery are of the size (didn't measure diameter but about 3/8 to 1/2) needed to fit on the threaded stud of a standard marine battery. Some have complained that this is a problem for their battery. But all the marine batteries i have ever owned have had two threaded studs and this is designed to fit over that - worked as intended for me. Now i can leave my boat unattended and be confident the bilge pump, etc. Can run without discharging the battery. I strongly recommend.

E. Finch, New Brunswick says

Worked great for a day, burnt out, they replaced was just a faulty unit. I have 2 others on my other boats. They are great, love that when your ready to go, battery's are always ready to go. Just a nice product to have at all times.

A. Brendon, Hamburg

I installed this in my diesel truck with dual batteries. Even in temps below zero the batteries are fully charged every morning and the truck starts effortlessly. This was worth every penny. . Now. Besides this, it is very heavy duty, very well built and wired, and required no modifications* to install it. . *for my application i need to lengthen one set of the leads about 18" to reach around to the other battery.

Q. Jackson, Florida says

This charger is awesome! its fast charging and easy to connect. The only flaw is that it doesnt charge completly dead batteries. (thats cause of the smart computer) i had to jump start my batteries with my car cause i didnt have a cheap charger thats able to. But it was easy to do so not too bad. Before i bought this charger ive been manually pumping my bilge tank for 3 months! haha. Now my bilge pump is cherry! thank you noko for saving me time and efforts! another tip is if you have 2 batteries in parallel no sence buy the 2 bank charger cause you only need 1 bank charger to charge both. (i bought it before doing research.

P. Rochelle, Windsor and Maidenhead

I didn't need a charger that would charge my batteries in matter of hours as some of your higher amp battery chargers can do. For me this works perfectly since i store my boat in my garage and plug it in overnight. The next morning all my marine batteries are fully charged and i can leave the charger plugged in to maintain the batteries.

X. Theresa, Lambeth says

Bought the gen4 in june 2012, it's now january 29 2016. The gen4 is charging the same 4 autozone batteries i installed in 2012 for a 48 volt outboard motor on a 26 foot sailboat. They have been heavily used several times but they still hold a good charge. I believe this charger is responsible for a good portion of their longevity. I will change out the batteries before summer this year just for my own peace of mind.

T. Julia, Darlington

Installed it on my 18 ft center console in the compartment my batteries are stored in. Took about an hour to install. I did swap the included screws for my own stainless steel screws but that is just my personal change in installing the unit. I mounted the unit on a piece of starboard and then mounted the starboard to the compartment. Made installation much easier for me. Hooked the unit up to my aging, hard starting batteries for 24 hours. Both batteries were charged up and started my 115 4 stroke without a problem. I plug it in once a month to maintain them while the boat is in the water. When they come out for the winter i'll be buying another unit to maintain them. I highly recommend this charger as it actually reconditioned my one older battery that i was going to replace this season.

I just installed the gen1 in my 2003 suburban 1500. I had to snip the eyelet adapters due to the battery design. I took off about 2 inches of wire sheath and wrapped it around the terminal bolts. I tightened the bolts (no copper wire is exposed). The fit was tight. . I then plugged it in. I got a blinking red led light (it should be a steady red light - indicating that it is charging). . I read the "trouble shooting" section. My best guess was the battery was too dead to charge. The pamphlet suggested jumping the battery to give it a little juice. I left gen1 leads in place. I connected the jumper cables to a charged battery. I only had to leave it on for 3 or 4 minutes. I detached the jumper cables and the error went away. That is, it stopped blinking red. It stayed solid red. After 20 minutes of charging (this time with no jumpers - just the trickle charger), the truck started. When i shut the truck off, the green light stayed lit. This indicated the battery is charged. I knew it wasn't. To fix this, i unplugged the extension cord. When i reconnected the power cord, the red light came on - this time with no errors. I repeated this procedure three times - all with the same results. So i think the charger is working. I will check tomorrow to see the status of the light. . I need to mount the box and install a plug on the bumper. I will probably install it under the license plate to provide extra protection from the elements. . So far so good. . The reason i bought this product was because the suburban has a slow leak. I could spend $500 to have it diagnosed, but i don't want to spend that much. I already dropped $500 to fix the main leak (drain). I will probably keep it plugged in most of the winter. . I hope i can find a good place mount the box.

Works very well. A little slow to charge a very depleted battery. It did bring a very very dead(sears, discount auto parts said replace it) battery back to life for me though. . Pros. Durable. Easy to setup. Charges agm, sla, and gel batteries. Charges mixed group and mixed type batteries. My agm deep cycle g27, and sla cranking g24. . Cons. ? couldn't find one. . After i tested this unit out for a few days in my garage on a couple dead batteries and it brought them back i went ahead and permanently installed it in my boat. A week after i had mine installed a buddy ordered one and subsequently had me install his for him.

While i haven't had it very long, i am happy with the general appearance of the material used in the manufacture, the size, and the connection cables. It works as it should as of this time and is simple to install. The different manufacturer unit i had before (from 20 years ago) was rough on batteries if left on for long periods of time and i would only plug it in just before a trip and that worked fine but is a pain. I talked to a lot of people before i bought it and looked at a lot of reviews and it scored high for price and function and everyone claims that it will not harm batteries if left plugged in. Only time will tell but i don't doubt that newer technology probably is a lot better.

I did a lot of on line reviewing before purchasing my genius 2 charger. I looked at many brand and narrowed it down to either minn kota or the noco genius 2. I'm glad i went with the gen2. I wired up the charger plug to a recessed outlet on my boat instead of the plug-in cord. The charger is small and light and give great power output for the money. 2 banks 10amps per bank. It automatically charges and then shuts off and goes into a "mainatain" mode. I charge both my starting batter and my deep cycle battery with it. It knows how to charge each batter based on the internal circuitry. I've used it about 1/2 a season (30 plus charges) and typically leave it plugged in for several days at a time. Batteries are perfectly charged and ready to go. I would highly recommend this charger to anyone who is looking for an onboard charging system for your boat. It beats the hell out of hooking up an individual battery charger after each trip. I just plug in an extension cord and i'm good to go. Online store. Com has the absolute best price on it too. I paid about $115 delivered and other sites are charging $179 or more! its listed on the noco site for $215.
