NOCO Genius question

[2515R Dude]

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?
