EXCELLENT Review! Legible tone. Straight to the point. Unboxing. Demonstrated how to use. This is how a REVIEW should be done.

I just want to say kudos to this man for answering so many questions .. you don’t often see that on videos like this. I’m looking into purchasing a pulse charger to revive a battery that I know is below 7volts and I saw, on another video, that while other chargers may not start the process if the voltage is too low - this one will. I also like that it can also do a trickle charge so it’s very versatile. It does cost a little more than the others but it’s worth it, to me, not to be concerned that I’ll get the charger and end up having to return it because it wasn’t able to detect my battery.

BTW. the green led information: The blinking green LED is just showing that the charger is in the Optimization portion of the charge. This can last for up to 48 hours. it happens right after the initial charge is complete, and anytime during Maintenance when the charger is 'topping' the battery off. This is a low current trickle charge that fully saturates the battery, repopulates the ions to the plates, and mixes the electrolyte bringing up the specific gravity. A good analogy is it's like pouring a beer into a glass. You fill the cup and then have to wait for the foam to go down before you can pour more beer into the glass. Then let the foam settle and you can add a little more, and so on.

I really like your video, great information. I plan on buying this very soon for use for my new car during winter months.

Thanks mate I was gonna get the other one 3500 but you sold me on this thankyou. Great stuff.👍👍👍

Nice demo, thanks. I just bought another one (5 amp) for my son's Christmas present. - N Idaho -

Does anyone know what the optimization mode does in the noco charging cycle? Mine seems to take 48 hrs+ to come out of the final optimization mode to fully charged..

and thank you for the straight forward video!

Richard, can charger be plugged in to battery as it is connected to vehicle terminals or only a "unplugged battery?" Thanks

Great demo , thank you.

Could you review it in more details, like, use a multimeter to monitor the voltage change from standby mode to force mode? for me, when it is standby, this charger output 16.5v in pulse every one or two seconds, and the force mode always ouput 19.6v which is super strange.

Just bought mine yesterday , one thing though , at 2:12 you say the clamps are solid copper , they are not , they're just copper plated steel , easy to test with a magnet .

Superb technical presentation!

Hi can I use this to charge one battery from another battery e.g. dual battery system in a car?

Thanks for the review

Hi Thanks for the review I do have a Renogy Deep Cycle Hybrid GEL Battery 12 Volt 200Ah ,What settings should I use on the noco G15000 charger? Thanks in advance

You failed to mention that in 12 volt Repair mode the battery should be disconnected from the car because in this mode only the charger can damage car electronics systems. It's in the fine print in the manual.

Great review, what is your opinion on Pulsetech PowerPulse passive desulfators?

thanks i appreciate this video gonna try this on my mercedes

saved me from buying a new car battery. good stuff

Thanks for the review. I just got a Gen 5 to try to bring the 12V battery in my 2019 Honda Clarity back to life. It went dead from prolonged disuse during lockdown. I wasn't sure what mode to try but went with 12V (the first one) since I couldn't find any info saying my battery was a different kind. It failed to charge on the first try, which was not unexpected. I then tried force mode. After 5 minutes of LEDs blinking as expected, instead of entering regular charge mode it started a pattern of LED blinking that was not in the manual or anywhere else I could find. The 12V LED (the first one) blinked fast a couple times, then blinked in unison with the 25% charged LED. Once those two were blinking together (slowly), they would alternate with the standby LED blinking. So the blinking pattern was 25% plus 12V, then standby, repeat, with an occasional solo flash of the 12V LED mixed in. Do you have any idea what might be going on? I don't know if there's something special I don't know about since my vehicle is a hybrid, if I'm doing something wrong, if this relatively new battery is beyond help, or if my Gen5 might be defective. (To be clear, it is only the "regular" 12V battery I'm attempting to charge, not the special batteries that make the vehicle a hybrid.)

Had AAA come out and replace a 5 year old battery in a Lexus that hadn't been driven much. The car was only driven about twice a month after that and one morning the battery was dead, as in no interior lights, no blinking security light on the radio. From what I hear, "not driven enough" won't get a warranty replacement. Bought the Genius 5 on Amazon, hooked it up, normal charge, not repair, and 24 hours later the car started right up. It's been fine since. Maybe the battery had been sitting on a shelf for some time.

Yeah I got this right when it came out I really love it sofar I had no problems with it! 💕

What happens after a power cut? Does it return to its last mode? Or do we have to do it manually?

Thanks for the presentation. One thing that is not clear is if the battery should be hooked up first before connecting the charger to a power source. I would think it be so, but does it matter if the sequence is reversed.

This Genius 5 beats the G 3500 hands down. More automated. Temperature stability. And allegedly safer. But always wear safety glasses when working with car batteries or and rechargeable batteries. This is a very cool looking piece of tech also. That is something important to many tech lover's..

Repair mode is 1A charging rate until about 14.5V and will start pulsing charge 1A until max 4 hours or 15.3V

🛑 Hi, thanks for the information. How long does it take to maintain the battery in an hour ??? And can he repair a 4-year-old battery ?? ⛔

How do you turn it ON? I just bought this, put it to charge but when I press the Mode button it doesn’t turn on. Or those it turns on when it’s connected to the battery?

Can you leave the NOCO connected to your car battery without disconnecting the battery when using the NOCO for trickle charging?

Is this useful for jumpstarting discharged batteries? So for example cars you haven’t used in months (particularly during the pandemic). I had to get someone’s help to jump start my car with another battery when my car would no longer start (even if the battery was less than a year old). Could this device be used in those situations rather than having to jumpstart the battery the old fashioned way?

I just got one of these its the genius 10, I'm wondering if I can safely hook it up to my diehard agm battery while connected to my alternator and just leave it for when I don't drive the car for a few weeks or so? will it keep my amg bat' topped off?

I have a NOCO G750 with the eyelets attached. If I switched to this model would it connect to the cord already connected to my battery?

Hi Richard - I have a 2003 Ford F250 diesel with two batters in parallel and just purchased the Genius 5. Do I just hook up the clamps to the appropriate terminals on the driver side battery and does the Genius 5 automatically trickle charge the batteries with low voltage?

Hello! Is there any advantage of NOCO genius 10 comparing to the genius 5, if you don't need the supply mode and 10 amps?

Do you know if I have to disconnect the Car's Battery Leads to use this Charger? Or can I literally pop the Hood and connect it up (with the Car's Leads Battery still connected)?

Will this work for a group 31 deep cycle marine battery? Thank you!

Want to use on a bike battery but the Haynes manual I’m using says should be charged at rate of 0.7 A (Yamaha sr125 1986) will this be ok or will it over charge the battery? I have other bikes and cars so would rather have a charger that will work on them all. Thanks

Is the lithium setting @ 5:49 for LiFePo4 or Li-ion batteries?

Can I trickle charge/maintain my battery by connecting it via the alligator clips? I ask because getting to the battery terminals requires unhooking a bunch of plastic clips and a plastic cover.

great review, I assume, it works in 230v ? and will work with ordinary 12 v batteries non maintain ace free ?

I have this charger and for the first few months (arbitrary, was taking detailed notes) it worked fine. This included switching out of "maintenance mode" and recharging the battery when loads were placed on them. My shunt would record essentially 0 amps when in standby and when I applied a load I could see the - amps for a while and eventually I would see + amps (varied based on load but the math was always "load - 5amps" as expected) as the charger sensed and began to replenish the battery. If I were plugged in and using loads my battery was basically always at 100% per my shunt indicator. And then I noticed when checking the battery monitor that it was at 90%, or lower depending on how long since I checked. Long story short, the charger would not come out of "maintenance mode". Unplugging and replugging would initiate a complete charge cycle back to 100% at ~5amps. But then the same failure to come out of "maintenance mode" would result. This is on a LiFePO4 100ah battery. I now have a heater assembly on the battery that draws DC power from the system as needed to maintain greater than 40F. The battery BMS has a cold temp cutoff circuit which was activating a few overnights before I had a chance to install the heating system. I see nothing in the Noco manual about this interfering with the charger sensing circuitry. Do you have any insight on this phenomenon? I've spoken with tech support and made no progress beyond offering to take my unit back to se if they can duplicate. In the meantime I've purchased a different charger but have not installed it yet. I'd rather not use that style charger as it is more of a hobby/workbench charger and not "designed" as a 12vdc battery system charger. I have high regard for the Noco brand but I cannot figure out why this is happening, beyond a glitch in the microprocessor and/or sensing programming.

Got my mounted per instructions and as soon as I started my rig it started smelling like burning wire. I disconnected immediately and smell stopped immediately so what’s up here? What did I do wrong?

So you don't have to charge it like other battery jump starts? Do you have to have it plugged in while you're charging a battery

So I just bought this charger and hooked it up to my 2007 mustang got that has the stock shaker 1000 system that has 2 subs in the trunk. The subs are making an intermittent humming noise with the charger connected. The battery is fully dead right now, hence why I connected the charger. It occasionally changes pitch as well. Does anyone know if this normal feedback from the charging system?

Hello Richard, Do I need to do anything special when charging the battery pack the first time, a specific settting on the pack I need to select? If my car battery is a 12 volt battery for a Malibu is there anything special, or do I just select charging for a 12 volt battery? Thank you.

Great video. Is this good for "all" types of Lithium motorcycle batteries?

Thanks! Is there a connection I can use to charge Quantum Turbo batteries? Also, can it charge multiple batteries at the same time?

Hi! I bought a noco genius 2 ah charger. The battery I have is a gel NPG 12v-40ah. Which mode to choose to charge this battery on a 12v or 12v AGM charger?

must it be plugged in to the wall to charge the battery or does it store power on its own ?

Can I charge battery out at winter around -20C? Does this charger support winter mode?

Can force mode be used through the sae port of motor cycles or is that not safe?

Hey, I just got this bad boy and the charger is SUPER hot. Is that normal with battery chargers? Never had one before. Honestly, it's SO hot I feel like it's going to melt my flooring. Also, my battery was at 50%, but it's been on the first bar for the past 2 hours... Help!

Can I start the car when it is connected to the battery with or without connected to the power? Will it ruin the battery if I use repair mode on a good battery. I just wanted to put it on repair mode on a 4-year-old battery. Thank You.

I bought it on Amazon and received and installed yesterday. The one I received was in much large box and it didn't come with any battery claps. Did they stop including them? The installation was super easy.

Hey Richard I have a question. I have 26 foot AGM batteries in my RV. I purchased the genius five but wondering if I use the 12 V AGM setting or put it into 6 V for a charge. I realize this might be an ignorant question but I don’t wanna make any mistakes. Thanks for your review and any information you can give me.

Hello I just had a question since I literally just bought this charger, is it able to charge deep cycle batteries?

When I charge my battery it goes from 25% to flashing green in about 20-30s. On all the batteries I have tested on. Is there something wrong with the charger? One is a new battery while the other are a old battery.

Anybody have any success charging / maintaining a Large LifePo4 (200ah) Battery's with one of these ??

Great review. Will this charger be sufficient to charge/maintain standard sedans such as Lexus and Honda? How is the GENIUS10 compared to this GENIUS5 (for example, what additional features on the 10 would warrant twice the cost on Amazon? And is it really needed?). I saw that your channel also reviewed the GENIUS10 review as well. Thank you.

What happens after repair mode. Does it go to charging? Does it stay on repair for a set period?

Does the repair mode work on AGM batteries or just lead acid?

Does the desulfator feature work? I was in the understanding I needed 250 amp charger to do this.

My question is do you charge the charger and store it in your vehicle or does the charger itself have to be plugged into an electrical outlet to work?

I bought a NOCO GENIUS5, what I sort of ran into is that it seems a little finicky around set up. So basically what seemed to happen is I set it up, plugin, select the the setting for the battery. I see it is at 25%, I come back the next day(2nd time) and it is still at 25%, which seemed suspicious, so I unplugged it, re-set everything, plugged it all back in using the cigarette lighter entry point. Everything looked right to me 1st, 2nd time with correct indicators to charge battery correctly. Same thing next day, I come back and still at 25%, so I repeat the setup again (3rd time), shoved it all back together, re-set to the normal battery setting. Frustration up two notches, I walk away. Now on day 3 the battery is solid GREEN and all charged back to normal fully charged. My gut feeling was somewhere in the works with the cigarette lighter plugin maybe not fully seated electronically. So it feels like 1) you better check on it after setup, 2) make sure everything is seated and connected good and tight 3) repeat if anything seems suspicious. I would not call this set it and forget it, keep an eye on things don't assume it can sense correctly what all is going on or pulse its way to success if connection is not solid. I doubt I would have had this had I connected directly to the battery terminals but I didn't want to go that route in a Porsche 997 where the battery is in the frunk and I would have had to leave the hood cracked open for the cable or come up from underside of the car snaked into frunk somehow which seemed like more pain than it was worth doing when the cigarette port is easily accessible. Any thoughts or comments appreciated. Is there a different approach to insuring a solid lock down on the 1st try.

Hi I am charging a 60AH AGM car battery for 2 days and charger indicator keeps flashing green not solid.Should i be worried?

I need to leave my car at the airport for a few days at a time in -15 to -30 C temps. My particular model is notorious for parasitic draw while parked so I would like to hard wire this and plug it in while I am away at work. I don’t want to have to pop the hood and hook up the clips every time. Is there any issue with running the vehicle while it’s wired? I assume the electronics will protect it if it’s just in maintainer mode?

What settings for sealed motor cycle

hi , i have a agm battery . can i use the repair mode for AGM battery , thanks

Does this work for standard 12v pickup truck batteries? Here is my battery Ssb 24REXT. If so would you use the 1st mode 12v?

Hi can I charge my car battery while it's connected to the car using the genius5 or I have to disconnect the battery from terminals

Does the battery have to be removed to use the 5Gen in Repair Mode?

I bought One of this for a battery of a Mazda cx-3 (1.8d with star&stop) to mantain the charge of the battery for a long stop ..the question Is: i have to use 12v normal or 12v Agm? Thank you

If I get noco genius 10, what will be different? Speed of charging? Or is 5 amps safer for regular flooded 12v batteries?

Hi man i have 6v battery and it’s over 4 hours plugged in and i still have flashing the first light only . Thanks for help

When I get it tomorrow, do I have to enter any specific mode when I hook it to my c6 2008 Z06? I want it to trickle charge and keep the battery at full charge.

Which 12V for the Optima Yellow Top AGM?

Is this for standard 4 cylinder Suzuki Swift car too ? Is it for Mercedes sprinter large van battery too ?

Hi I've just bought the Noco genius 5. I've hooked it up to my flat battery which is only a few months old. It's pulsing red, one light only. Like the light dims and goes solid then doms again and goes solid and so on. It's been on charge for about 24hrs now, nothing has changed, it's been pulsing since. According to manual, red pulsing means it's under 25% charged. It's been 24hrs surely it would have charged over 25%, or is my Noco a lemon?

Hi, i bought a genius2 , for how long it will take to charge my battery , I started to charge for 8 h and I still have only on light 25% still blinking

Will this charger charge 12v deep cell marine batteries?

For Repair mode,i need to have in stand by,then press for 3 seconds and once more. Then i leave the red 12V-repair light to blink until it is over...or? Tnx

What would happen if you selected the wrong mode for the charging. For example, using a Lithium mode charging on a AGM battery.

Just won one of these from John Pye auction £34 bargain.....if it works lol I have a car in the garage I only use in the summer so bought this more as a battery maintainer

So if green led is on it means its fully charged ?? Because mine is blinking on green !? Is it charged or do I wait until its solid green and won't blink ?

Thanks for the video. So are you supposed to keep it hooked up to your car so it can replenish the battery anytime it dips?

does repair mode even exist for an AGM battery ?

One question. Do I have to remove the dead rv battery under my hood to use this device in the house? Or is this device chargeable with the tail end plug 🔌 n the just go outside and clamp it to the battery while still in place under the hood? I’m confused how to actually use it. I purchased this today

Quick question to your great review! Can we use repair mode without removing the battery from the car?

Does the 'force' mode apply to 6v batteries ? Good review - no blurb 👍

Can I keep the battery inside my house to charge or does it have to be plugged while the battery is in the car?

Can I use it while the battery is still hooked up to the car, especially when starting a very dead battery 🔋 🤔

Will this work for marine deep cell

Which one to get for an Odyssey 1500 this or the g7200?

Lets say we are in camp site with power outlet, can I charge the car battery with noco and plug a heater to the car cigarete lighter?

I can't get this to charge SLA batteries(tried 2 genius5). tried 12v 6a and eventually tells me they are bad batteries. I hooked up a meter and I did notice its pulsating 19v ever 1-1.5 seconds to the battery. not sure if that is normal.

Great review! Is it OK to repeat the Recovery process several times in a row?

What about motorcycle sealed maintenance free battery?

hows the charge time compare to g3500?

I need a charger to keep in my car in case my battery dies when i'm at work. What do you recommend?
