I'm not sure that a trickle charger that works for NiCd is ok for
NiMH, and I am positive that a fast charger for the one will NOT work
right for the other. Each battery technology has its own charging
rules -- lead acid, NiCd, NiMH, and the various flavors of Lithium
battery are all different in very significant ways.
