NOCO Genius question

[RayIN]

Last week i bought two NOCO Genius1 chargers/maintainers.
I put them on two different batteries, one is 800CCA marine and another is a small 230CCA ZT.
Both batteries were fully charged before i connected NOCOs. Both chargers were blinking red light for a few seconds then went solid green.
It is already 4th day they are on and still they are solid green without going to the next step - blinking/on/off green which indicates "maintenance" stage.

The question is, is it a normal behavior?

Yes; a lead-acid, which includes AGM, self-discharges at approx. 3%/month.

if you have 3 meters, then just check the amperage, if its above 500ma its still charging.

If i do it means i have to disconnect the charger, then when it starts again, it starts charging it with 14.5V, So i dont see the real picture, right, or there is another way to check it?

Well, all i know is mine go solid green after fully charged. And testing the batteries show that the chargers arnt outputting when solid green.

If they are not outputting anything, what is the point? Shouldn't they do something, fluctuate/trickle? Just trying to understand the process.

When i look at noco site, i see 2 Completely different descriptions on charging led indicators. I see green flashing for fully charged, and i see this under support.

Looks like for their cheaper version they do nothing special, the rep could not give me any sound answer how it supposed to work. I guess they wanted to get in to a niche of cheap maintainers using their name they earned on more expensive models and using cheap Chinese junk.
It looks like it made in china or somewhere there, but what doesn't nowadays LOL.

Care to explain how it is related to this charger? How it prevents it from going to the float stage?

2015 asked: Care to explain how it is related to this charger? How it prevents it from going to the float stage?

It doesn't. I was just pointing out it's not necessary to have unused batteries on a charger constantly. A stored LA battery is fine without a maintenance charger for at least 6 months, so why worry.

These are not battery trickle chargers, they dont maintain constant power output. They shut down until power drops to a set amount, than charger starts cycle again. I have attached a dc amp clamp on the positive cable and i see the amp draw during charging. Once the light goes solid green, amps drop to 0.0A.

 

[LittleBill21]

you use a dc clamp meter. you do not need to break the connection, yes i wish the lights were a touch more accurate, but at the end of the day it doesn't matter, if it finally goes to green pulse, its in float mode.

I dont have DC clamp meter, only AC one, i guess it is the next item on my list i have to buy. Thank you for all your advices.

PS. The mystery resolved, one of the NOCO was defective and my luck, the one i was playing with.
Before returning them i checked another one and it works perfectly, charging -> optimizing and then go to floating mode, also immediately recognizes the voltage drop after i apply a load.
One going for exchange, another is going to go to the active duty in my barn. Sorry NOCO for bashing you

Dude, you can buy a DC/AC clamp/multimeter off Amazon for <$60. Mine works as advertised.

Hey, your 50% success rate is twice as good as mine.

Chinese junk.

Actually, they are all made in Vietnam. Could be why they don't work as advertised and don't check the amperage output with an Amascon Chinese meter either. The Chinese don't get along with the Vietnamese very well....

I received a NOCO Genius5 today and immediately connected to my CFMOTO Uforce 600. I connected a 'permanent' pigtail connections to the battery terminals. It started out showing one red bar. After a few hours it now is at a slow pulsing green only. It's working as intended. Yay!

I just check on mine. 10 amp. On a school bus I bought. Dual 12 volt batteries. Installed this afternoon. I looked at it and the green light is continuously on. One of the red lights is going off and on. So I can only presume all is well and it’s still charging. If I were to check the amperage out put I would take a different approach I would check the ac input with a multiplier on it times 10. The I would do the math. And I could see the fluctuations if there are any. And I will do this another time it’s been a beautiful day here and I am beat.

Is that true they are so cheap, i remember last time i checked they were well north of $150 and i thought i have enough testers to buy another one.
Yesterday i found (recalled where it was) another one which was my father's. It is over 70 years old and still works. The only problem it uses some kind of batteries they do not make anymore. So, many functions dont work.

Could you please see if they are what they claim to be?

you need the second one

the first one only does ac current

Oh, ok, i did not catch the difference. Would the 4000 count be enough for car/tractor work or 6000 would be a better option? Frankly as i understand the count term, 4000 should be plenty, but need a confirmation. I have only very old AC clump and never use it, so no experience.

 

[LittleBill21]

4000 count is fine

Thanks, ordered, will arrive on Friday with the replacement charger.

We have three 1 amp NOCO (1 indicator light) and one 10 amp NOCO (4 indicator lights) three are red and one is green.

The three chargers lets be due the 36 volt golf cart in one pass but doesn't give me a lot of detailed information. The 10 amp with four indicator lights lets me figure out what is going on better.

I find it can take weeks to recover some batteries, especially if on a car that has a parasitic draw.

I have not played with the lithium battery charging feature yet.

If one has 15 or 20 batteries that you want to keep usable I recommend starting with no less then the 10 amp version. Cleaning the sulfur off of the plates can take a long time.

Also, my noco 10 has 3 orange/ red indicators which light up in sequence as its charging. Than goes into pulsating green. By the next day its solid green.

I have a 1, 3 and 5 amp charger and that's all I have ever seen over maybe five+ years.

 

[Mcdust]

it NEVER go to the "pumping" green mode. Stays solid green. And the voltage is constant 12.7V so far.
How long does it take till is starts "pumping"?

Have you checked the inline fuse on the charger wires?

wouldn't turn on without the fuse working
