Charging antimony-free VRLA batteries without float
Here is a proposed much lower float current method to charge non-antimony batteries. Supposedly better than traditional float. Low current float for AGM

Mex what about this paper? They seem to be on the "some voltage below ideal float" band wagon too?
I'm not a fan of the charge and sit cycles since you skip from one size of the positive plate corrosion curve to the other without much time in the sweet spot in the middle. But there does seem to be a set of researchers thinking the reduction in dry out may be worth some balance above Voc but below Videalfloat.
More research into floating below theoretical ideal float voltage for AGMs
I actually hit this paper researching to find out the effect of Temperature on a battery's open circuit voltage. I can find a few references to the idea that it changes, but no pointer to how much it would change by so far.
