bb is right the charge rate should be no more than 14.4 volts at any rev amount ,a battery that epmties itself is a clear sign that the charge amount is too high and its boiling the acid in it and evaporating it.check the charging rate with a multimeter on dc accross the battery whiles it running at about 5000 rpm.

Your cooking your battery. Your regulator is more than likely at fault.
