I'm having a discussion on another group with someone about battery
charging. I often charge my batteries including automotive off my
bench power supply. He was telling me that smooth regulated DC is not
the best thing to use for charging batteries. He said that half wave
rectified unfiltered DC will prevent the growth of "dentrites" that
can eventually extend and short out the plates. This is the first I've
ever heard of this. Does anyone have any further insight on this? Lenny
