Low battery voltage level

Ask the customer how long a dip they would tolerate without a warning,
and why. An intellegent answer may require some dialog. And wouldn't a
large time constant filter =miss= momentary dips? That's what it's for -
to ignore the quick stuff and only warn on the more permanent stuff.


Yes, this is what I meant, filter out the momentary dips so it doesn't
trigger the warning.
