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?

I have them on all my 6v tractors, that’s how they act. Some work at different speeds between modes, guess every battery is a bit different

the lights are based on voltage., they blink green for a long time, while pumping out full current.

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"?

put an amp meter on it, how much current? 12.7 is not full charged, they rest around 13.2

Sorry I duplicated your post sir. I’m not sure how to determine a fully charged battery with these. I think it’s almost completely green I had one intermittently blinking and it would not start my car. Left it on until the next day and it did. And it was almost on all time. I have the 10 amp. They are good chargers

It starts from 13.9V with red pulsing, then go to 12.9V with solid green, then go to 12.7V with solid green.

You would need a dc amp meter like this to determine what's going on.

It starts from 19.9V with red pulsing, then go to 12.9V with solid green, then go to 12.7V with solid green.
19.9 is a bad sign, typically indicates the battery is shot, do you have a load meter?

Did you by any chance get them from Amazon?

If so you could've ended up with one that I returned after it killed a previously perfectly good H7 AGM battery.

Like you, I started with it fully charged, but after a couple of days that battery was down to 7 or 8 volts, and could not be saved.

it didn't kill anything you had a bad battery and I proved it in the other post.

I bought 4 of them from amazon, and they work fine. go read the reviews. they are the number one charger on the market.

Mine start red, later go to a pulsating green, then a solid green. Ihave 2 of the 1 amp, they both do this. Checked battery voltage, 13.2 after solid green. One is set standard flooded, the other is on AGM for the tractor.
 
   / NOCO Genius question #15  
Have 2 Noco chargers 2 amp and 10 amp. After the red/orange are lit the green will pulse maybe 20 minutes then the red/orange tuns off and green will be solid. 24 hours later green will still be solid

I have 3 of various levels from $5 to $240

Typo, should read 13.9V The batteries one year old and tested good

Yes, from amazon but boxes where unopened and all wires looked like never being used

As i understand it should be the opposite, first fully charged then go to "pulsating" - maintenance mode

I was chatting with NACO customer service, and as i should've been expecting they were useless, but they say, the charges starts in High voltage up to 14.5 and when it charged to 75% it goes to 12.9 then as it gradually goes down and when it reaches 12.7v-12.5V it should go to the maintenance mode and start pulsing.
He told me to send the charges for testing on my dime. I said "Thanks, but no thanks"

I also have a Schumacher one, it does exactly like this is is expected, Charge (solid yellow)-> Maintenance(Pulsating green)

That's what they told me, too. And I also said "Thanks, but no thanks."

And all my other maintainers also have logical indicators.

if you have 3 meters, then just check the amperage, if its above 500ma its still charging.
 
   / NOCO Genius question #19  
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.
 
   / NOCO Genius question #20  
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.
