Product Description

By entering your model number, you can make sure that this fits.
The all-new GEN5X3 is similar to our GENM3, but it's even better. It's 3 37 smaller and 43% more powerful. It's one of the most reliable onboard marine battery chargers we've ever produced.
Multiple banks - A three-bank onboard battery charger rated at 15 amps (five amps per bank) for 12-volt batteries such as marine, boat, starter, and deep-cycle batteries.
Selectable charging modes - including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode - for all types of lead-acid and lithium-ion batteries allow you to charge and control each battery bank independently.
Enjoy precise charging - A built-in thermal sensor detects the ambient temperature and adjusts the charge to avoid overcharging in hot climates and undercharging in cold climates.
Charge dead batteries - Charges batteries as low as 1-volt, or use the all-new force mode to take control and start charging dead batteries down to zero volts manually.
Simplified mounting - With an integrated anti-vibration backing that isolates shock, vibration, and noise, a simplified mounting system allows for quick and easy installations in any direction - even upside-down.
Designed for water - A fully sealed and waterproof onboard battery charger with an IP68 ingress protection rating that has withstood rigorous life cycle testing, including thousands of hours underwater.
Type of Fit: Universal

Questions & Answers

My project is a 36-volt golf cart (3 x 12-volt batteries) - Is it possible to use this as a battery maintainer (one "channel" for each 12v battery)?

Yes. Channel 1 is connected to the first battery, channel 2 is connected to the second battery, and channel 3 is connected to the third battery.

In a series, I have two group 31 deep cycle batteries. Is charging time longer with this charger when they're connected? What exactly is the distinction?

As long as the battery isn't getting too hot, it should charge just as quickly either way. Your batteries will not be harmed if you leave the charger plugged in all the time. When the batteries are fully charged, it will automatically go into standby mode.

Is this compatible with all 12V car batteries?

Yes, it is compatible with both 12 and 24 volt systems. It also tells you if your battery is dead, which I really like. You'll adore it; it's fantastic!

Is it supposed to stay lit after it's been disconnected from the marina? Mine is turned off while the boat is on the water. ?

When you unplug it from the power source, it does not stay lit.

Purchase is not recommended
3/5

  I bought this about 6 months ago, and it has since stopped working, as seen in the video. It did an excellent job of keeping and charging my trolling batteries during the time it was operational. This, however, was not the case. I contacted Noco about this problem because I thought the warranty was for three years. However, it appears that cutting the leads to extend the DC wires (which is required on at least one or two of these units) between the unit and the fuses voids the warranty. That does not sit well with me. It also doesn't say anything like that in the instructions, as far as I recall. You must cut between the fuses and the eye connector if you want your warranty to be void. Which, in my opinion, is a blunder. But now I know who to contact, such as Minnesota Kota or Pro Marnier. Because theirs still covers the warranty regardless of where the leads are cut. Just a heads up to anyone considering buying it. This amount of money is unacceptably high for only 6 months of use.

It was an excellent solution
5/5

My 24v trolling motor bank and 12v starting battery worked flawlessly together. As a replacement for an older unit, this unit is simple to install.

The charging performance is excellent
3/5

I'll have to return it if there are no quick disconnects. This product isn't meant to be used in the garage. A one-star rating is a little harsh because the charging and repair functions are excellent, but the lack of a quick disconnect has brought it down. I have the Genius5 and was under the impression that this was essentially a 3-in-1. 1 waterproof version to set up in my garage for vehicle trickle charging, winter RV battery storage, and battery desulfunation on occasion. So I assumed that this, too, would have the same quick disconnect as the Genius5. Nope. Because the leads are permanent, batteries must be removed from vehicles and transported to the charger, or one vehicle can drive up but the closed loop eyelets must be wrenched on and off each time; or I could void the warranty by cutting off the ends to crimp on quick disconnects. This review may come across as "you're slamming a product because it doesn't do something it wasn't designed to do?" " And there's a grain of truth in that- The charging is excellent, and it would be ideal if I wanted to mount it permanently on a boat. However, given the price, it should either include quick disconnects or make the form factor clear. It doesn't help that every Noco product is "genius" or "gen," as if you need a Noco-specific noco-specific noco-specific noco-specific noco-specific noco-specific noco-specific noco-specific noco-specific noco-specific noco- To determine the product lines and what you're purchasing, use an English dictionary. In retrospect, I should have just bought a bunch of Genius5s when they were on sale. Not only do you get all of the same charge/repair features, but you also get 24v flexibility. The only concession you make is better waterproofing.

Without a doubt, it's worth the money! I own a Noco genius for the second time
5/5

Both of them performed admirably. Because I bowfish, I upgraded to a three-bank system. As a result, I go through quite a few batteries. This new product is sleek, light, and simple to set up. It's been charging all of my batteries since I hooked it up a few days ago. Any other battery charger would be a waste of money in my opinion. I hope you find this information useful.

Out of the box, it's a disaster
3/5

My team unpacked it and handed it over to me to put together. It would only power up for a second after being connected, causing our breaker to trip. Because we didn't have the packaging, I sent it back to the factory for warranty. I've been waiting 45 days for a response to tell me when I'll get it back, and they have yet to respond. br>br>Spend more money on a genuine brand; what a waste. br>br>Updated on June 22nd. I have yet to receive the warranty unit. Our shipping department isn't connected to us, so we can't tell you when it'll ship or if it's already shipped, according to customer service. They recommended that I enroll in UPS and FedEx alerts. Really? I get a lot of packages, and I don't want to get bombarded with emails from UPS. Their customer service is so bad that the department should be renamed "I don't care. ".

CAREFULLY READ THE DETAILS
3/5

MARINE - PREFERENCE IS GIVEN TO THOSE WHO ARE ALWAYS IN CONNECTION. I own one of their jump starters and am very happy with it. I was surprised to find it on Prime Day for such a low price, so I bought it. I'll admit it was my own fault for not reading carefully - I have multiple summer vehicles that I wanted to quickly connect and disconnect for a charging device. This unit, on the other hand, is designed to be ALWAYS CONNECTED to the devices it's charging, with only one cord leading to the wall. As the saying goes - These would be hard wired to a bank of three batteries in a boat - After that, you'll only have one connection to deal with - However, it's not something you'd want to easily connect and disconnect on a regular basis. Adding insult to injury - br>br>br>br>br>br>br>br>br>adding I wanted to switch to the correct version, but Prime had expired by one day by the time I discovered the issue, and they wouldn't honor the price of the other unit - As a result, I returned.

For the money, this is a good charger
5/5

I purchased a "like-new" used one from an Amazon warehouse. Although the outer packaging was a little scuffed, the internal packaging was still shrink wrapped and in perfect condition. As soon as I received it, I put it in my boat. Easy to install: Two self-tapping screws easily attach it to the battery compartment wall without the need to pre-drill. The most difficult part was removing the Compton from my battery in order to install the chargers. On each bank, I plugged it in and pressed the power button. Bam! It worked flawlessly; obviously, we'll have to wait and see how it holds up over time, but NOCO is a well-known brand, so I don't expect any problems.

This is a good charger
4/5

It was very simple to set up. It appears that the batteries are charging properly. I freaked out at first because the percentage of charge after a fishing trip showed way more use than it should have. This showed I had under 50% left on my Lithium batteries However, the charge time was only 2 hours which tells me it was More than 80% left on 60ah batteries.
