Cleaning seems to have worked on one malfunctioning slot, but the other finicky slot will not charge/discharge above 30mAh. Not sure what that's about.That cleaning certainly could help, so let us know.
I will, thank you. As for this charger, I'll probably just be resigned to a 3-bay charger until eventually buying a new one.Do however consider picking up some D100 for electrical contacts / connections going forward.
