US Battery recommends: Batteries should always be watered after charging unless plates are exposed before charging. If exposed, plates should be covered by approximately 1/8″ of electrolyte (add distilled water only). Check electrolyte level after charge. The electrolyte level should be kept 1/4″ below the bottom of the fill well in the cell cover. See attached picture for reference.
I found that when I tried to follow the US Battery recommendation, I had excessive acid pooling on the tops of some of my batteries after changing. My US batteries are 6 volt and equipped with Speed Caps (see attached image).
I now keep the electrolyte level
about 1/4" ABOVE the plates (or best that I can estimate). There is now considerably less acid pooling after charging, but I find that I have to keep a closer eye on the electrolyte levels now with less fluid above the plates
