PT, I suppose you are right; you can join smk in his belief that a slow charge has a "higher quality" than a fast charge that gets the battery to the same SOC.
I don't care really, I just want that SG to show the battery is up where I want---the sooner the better!
The thing is, I don't believe when the SG gets there with a faster charge that it will then fall back, where if only it got done with a slow charge, it would stay there.
Doesn't matter while camping anyway. At 5pm, or whenever, when battery SOC has peaked, it is time to start supper and eat up some AH and that's that for SOC. Any solar from then on is nice, but can't keep up with usage till dark.
