3. Nobody knows yet. In any event, a properly-designed charging system
should hold the battery at around 13.5V.
And if you draw down below 12 volts you generally destroy the battery
if you repeat this very often or go significantly below 12 volts. But
who cares about that if it's field day and you want an extra 5 minutes
out of the battery?
