No that's not the float. If you charge the your float voltage your battery may not get full in the span of one day. I prefer not to throw away solar production so I like to charge to full.That's basically what I'm getting at, yeah. When the CV absorption current tapers all the way down to near zero it's a matter of terminology if you want to call that the float or just the tailed off end of an absorption phase. I'm still calling it the float. And it does end after a few hours anyway, like you say if this was a 24/7 charging standby power application the considerations would be different.
