FLoat it with a well regulated power supply at 13.6 volts and you'll
be mopping up boiled-out battery acid a lot. 13.4 is the highest I'd
go on a float basis. 13.6-13.8 on an intermittent basis.

All I can say is that while working the last 32 years for one of the
countries largest Telecommunications Organizations, we floated all our
thousands of communications battery banks at 13.6 volts with excellent
results. No batteries dried out prematurely due to this float voltage...
in fact that is the figure recommended by a number of top battery
manufacturers such as Exide, GNB, C&D Technologies, etc.
