Thanks for pointing out that when fully charged the green light will remain fully lit. My first time to use my Genius 10 and I have a flashing green light for nearly an hour and was unsure if constant illumination is expected. I’m surprised how difficult it has been to find this confirmation. They should have provided a how to use manual with the charger.
I've been charging my 90amp hour deep cycle for 2 and a half days now and the green light is still flashing. Was wondering how long it can take for the green light to turn solid?
The flashing green is just a trickle/maintenance cycle but it technically fully charged per the manual at that point so you can unplug it whenever. I have had it trickle for up to 4 days before then go solid, then a couple hours later it will start flashing again. From what I have experienced it is just "optimizing" so it will indefinitely cycle between solid green and flashing forever as long as it's plugged in and attached to a battery which is totally normal.
You can use it to maintain your settings while you remove and exchange the battery. You can only remove and charge the battery ONLY IF you have another charger.
I’ve read that you can use this while the battery is still connected to the car. Do you think there would be any damage to a subwoofer amplifier I have connected to the same battery while charging?
No worry for damaging any of the electronics like sub amp. I almost exclusively use it while the battery is hooked to the vehicle. It puts out basically the same voltage as your alternator (owners manual says up to 14.5V for standard 12V) but at much lower amperage than you alternator (10A, hence NOCO Genius 10) so very safe on your cars electronics when used in accordance with the owners manual.
@@JohnSnow-gd9dj You just choose which mode (e.g. 12V, 12V AGM, 6V) and let the charger do the rest. It will charge if the battery needs charged, or just maintain if the battery is full charged. It decides what is best for the battery after you've told the charger what kind of battery it's attached to.
I was wondering why my new Noco Genius 10 won't go into repair mode? It won't light up but all the other modes light up? My battery must be pretty dead because the charger keeps going back into Standby too...hmmm Thanks for the video👍
Hmmm... not sure. My guess would either be what you said (battery is beyond hope) or you received a bum unit. If it's the latter you could return it to where you got it or cash in on the 1 year warranty with the manufacturer.
Perhaps too much information to put in the user manual button descriptions on page 4, but the manual's following page 5 has explicit details for "Using 12V Repair" where one of the statements includes "For optimal results, take the 12-volt battery through a full charge cycle, bringing the battery to full charge, before using this mode."
I'm getting this tomorrow and have a 12V car battery that reads roughly 12 - 13 on the volt gauge cluster in my Jeep. I just replaced the 15 year old stock alternator that wasn't supplying the battery with enough power anymore. How do I charge the battery so it gets back to 14 or better on the volt gauge cluster?
A fully charged 12V battery should read anywhere from 12.4 - 12.8V when you put a handheld multimeter on it. This NOCO charger will charge the battery at a higher voltage (13-15 volts depending on the health of the battery) in an attempt to raise the voltage of the battery to it's healthy range (12.4 - 12.8V) but when the charger reaches it healthy range the charging stops and the battery will settle out in the healthy range. With a freshly charged battery and a healthy alternator you should see something like 13-15V on the gauge cluster with vehicle running. (With the vehicle not running but just the ignition on 12-13V on the gauge is perfect). If not getting 13-15V while running. I would suspect either the battery not holding a charge, the alternator not charging appropriately, or the gauge isn't reading correctly. The best way to check would be to put a multimeter on the battery with the vehicle running and check the DC voltage and see if it matches your gauge. If yes and the voltage is too low while running, suspect a battery or alternator issue. If no, suspect a gauge or wiring issue. Hope that answered your question. Good luck!
@@JeepTJWheelin Yup, it is "optimizing" the battery. From the manual: "Pulsing Green LED - Bulk charge complete, optimizing battery for extended life." In my experience this means it is trying to desulfate the battery or get the battery just a tiny bit topped off (e.g. bring the battery from 12.4V to 12.6-12.8V). For all intents and purposes it's fully charged when it is blinking green, but if you have time to wait it will eventually finish "optimizing" and be solid green. There are no issues if you need to get the battery off the charger during blinking green LED (plenty of charge to start and run the vehicle).
Nope, it's a charger and not a jumpstarter so would be useless out in the boonies. For a jumpstarter I would recommend the GB70 I made a video about that as well: ruclips.net/video/kfN2SpmpK1k/видео.html
very informative video, 1 question, can I use this as my deep cycle 250 ah lithium ion back up inverter charger?, any advice on that, can I just hook it up n leave it ?
Should be able to per the owners manual it can do lithium ion 12V though I've never personally tried using it with lithium ion. Yes it's designed to hook up and leave it.
@@many-points found an icybreeze cooler to do the trick; it aint a cheap investment but gas prices becoming what they are i figure this thing'll pay for itself within two months (i'm in my car for a minimum of 60 hours per week haha) Thanks for your feedback!
I put the no go to on my jet ski battery came back A couple hours later it had boiled my jet ski battery would not let me put it into 6 V this is the no go genius thanks no go WTF

After a full charge like that, I would switch over to a repair mode. Full charge, then repair mode
Its also recommended like that in the instructions
@@davidkay7389 Great point. He might not be getting the solid light because it could use a repair, doesn't hurt to try.
You can use it to maintain your settings while you remove and exchange the battery. You can only remove and charge the battery ONLY IF you have another charger.
True good point.
To maintain settings while change battery, you connect to car batter cables ?
@@babagandu correct

@@many-points To be use in " sustain mode" or in normal charge mode?

I read to remove battery from car while using reconditioning mode to protect car electronics
Nice video...Anybody have any success charging / maintaining a Large LifePo4 (200ah) Battery's with one of these ??
I've never tried a Lipo battery with any NOCO product. Would love to hear if anyone has tried it and had success!
We appreciate this review man
Is it reliable, does it last long hopefully?
What do you think of it so far 💛
I haven't had any problems with it yet and have done 30+ charges to date.

Will it charge two 6 volt batteries
I don't think so. I think it is designed to charge one 6V battery at a time.
So this wouldn't jump start a vehicle out in the boonies where you would not have an outlet to plug it in?

can this help me avoid idling my car 12 hours a day at my job this summer while still running my car AC on the battery? 2018 maxima
No unfortunately, a 2018 Maxima uses the drivebelt to run the AC compressor so engine has to be on to run AC, this item will not help with that.
