The lowest setting for the MKII is 200ma. I thought that wasn't low enough to slow charge a 600ma battery. Isn't a slow charge C/10? The lowest setting that you can get a trickle charge on this model is 600ma. You said you wanted one that doubled as a slow charger which is why I posted this. If I'm wrong, someone correct me because I have this model and was told that 200ma was too much to slow charge even a 1400ma battery.
