Noco bank charger

Anyone have experience with Noco bank chargers? Bought one secondhand off a guy on Facebook for $60. He says it came off his 2019 Nitro and he only replaced it because he needed a 24V system.
I hooked it up, knowing both batteries were pretty much fried. Used them all day Saturday till they were both dead and then had to be towed back to the dock.

So this is Wednesday, I hook up this charger I bought. 2 bank Noco Genius mini gen 2. My batteries both had 5 volts. When I hooked it up, my one battery immediately showed 14 volts. The other battery continued to show 5 volts. I let it charge for several hours. The second battery still showed 5 volts.

I looked up a user mannuel for it online. It says the red light means charging. The first battery had green flashing light. The second battery had solid red light. I checked the connections and the fuse, all looked good, but it still showed 5 volts. Checked it again when I got home from work today and it’s still red, but now showing 14 volts. The other battery is showing 13 volts but is now solid green light.

I disconnected battery 2 from the charger and put my regular Schumacher charger on it and it still says it’s charging. So I dont think it’s full or it would be showing the charger in “maintain” status.

Any one have any experience on these that can elaborate on what I’m experiencing?

Have had the same issue with A battery that was drained almost completely! Hooked it up to a high amp charger and gave it a hot charge and it has worked fine since but haven’t drained it down that far again ! I always plug my boat in as soon as it hits the garage ! Or as soon as I get to a power source and I keep it plugged in until the next trip!

This is by far the best thing you can do to prolong battery life.

Did you try swapping the charger leads?

I agree completely. For sure, do not let a discharged battery sit for three days. Or even one day. Get a charger on it ASAP.

My previous boat had a minn kota 3x15. I ever let a battery drain below 7v it would not pick it up. I'd hook it up to a portable as previously stated. Then it would take off charging.

Some chargers will not charge a battery if it is below a certain volt threshold. "For safety", they say.
Two options that work for me in that instance:
Option one - Hook up an older charger without the safety circuit (I have an old "Silver Beauty") and it will do the trick, but if you don't keep an eye on it, it will not reduce when fully charged and over charge your battery.
Option two - Charge two batteries at once connected in parallel with a "Reasonably Good" charged battery first in line to your charger, then the discharged battery downstream in the parallel. The safety system will read the "Good Battery" voltage and allow charging current to flow and it will charge both batteries.
Many good battery chargers have been thrown away assuming they were bad, when in fact they were simply not "Triggered" by a decent voltage to the designed safety system.
I heard an electrical engineer once say to throw away all your old battery chargers, they are not good for your batteries and are dangerous. Perhaps so, but I have a hard time throwing something sentimental away! Especially if they helped me out in a bind!
