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

You never want to either. It is an extreme recovery procedure for an otherwise dead battery. Lifeline has one for batteries that have run dead and some other recovery procedure too. I used only as a last resort and it did work, but guaranteed the battery was stressed. It was not valve noise, it was a bubbling/crackling sound inside the battery.
