John, my alternator puts out 14.8 volts according to my voltmeter.  You want
greater than 13.5 volts or else your battery may not fully charge (of course
depends on the type battery you have).  The deep cycling type batteries
generally take more volts to charge than the old wet cell car batteries.  So
you may not have a problem depending on how much over 15 Volts you are
getting.
