Noco Genius 10 not working correctly

[Dellmassive]

here is the results from the CTEK.

2 days later the charger is still running the loads . . . similar as the Victron unit.





here is the BM2 plot.








i managed to get the charger to restart the cycle . . .

but only after throwing a massive load at the inverter, causing a volt drop . . .

the charger detected this and restart the charge cycle after the battery volts dipped below 12v.




at that point the cycle restarted. . .







that shows that the CTEK smart chargers can be used as charger/power supply when on EHU.




test end - definatly this time.

Well I've now got the victron fitted, dont have the fridge plugged in yet but will give it a try next week!
Out with the old

and then when the victron was plugged in


And then after a few hours

Just popping in to add my own experience with the Noco Genius 10 (and the 5, which seems to work the same way):

agree with everything that was found that the Genius line doesn't want to function as a "maintainer" if you have *any* sort of constant load on your lead acid batteries. They claim that it will go back into "charging" from "maintenance" mode (with the Green led flashing) if the voltage drops, but I recorded my battery at 11.99V and it was still sitting there looking stupid with the green led flashing like everything was fine. This was with a relatively small constant discharge in the neighborhood of 1A.

I also experienced where it gave up completely and decided it was a bad battery, probably because it thought the voltage was dropping too rapidly. And that can only be reset by power cycling the charger.

So if you're stuck with a Noco charger then you might want to put a automatic timer of some sort on it to power cycle it every few hours and force it to top up the battery that way. I'm just going to buy a Victron one instead.
