Here's an informative site ...
http://www.uuhome.de/william.darden/index.htm
... and I've also read elsewhere that deep cycle battery life is maximized
by minimizing the discharge ... maybe I'll find that site again.

I have just bought a couple of Delphi Freedom marine deep cycle
batteries
for my service bank. Is there a recommended minimum voltage below which
one
should not discharge? Also, if the nominal capacity is (say) 100Ah, is
that
measured between standard voltages or is it measured from a nominal full
charge (with full charge voltage dependent on the charging system) until
totally discharged - ie 0v? Or is there a standard "never go below"
voltage
which manufacturers use?
I have an intelligent battery charging system on my boat that charges up
to
a threshold 14v with an asymptotically decreasing charging current, and
a
battery controller with which I can set alarms to warn me of impending
doom
on the discharge cycle. At what level should I set the alarm to get best
use
out of my batteries?
