NOCO Genius question

[Mike1955]

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.

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

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

Amazon.com

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
