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?

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.

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!
