The only setting my charger has for nimh and nicd cells is "Sensitivity". It lets you adjust the mV per cell. I have no idea what this means, have never had to deal with this problem before lol
Its worth noting that I also have the same problem with single nimh cells as well as the nicd's. I dont have this problem with lipos or any other battery that has more than one cell. It seems to be just a problem with charging a single cell. Been scouring the internet for hours and cannot find any digestible info on this anywhere
