2000 Sentra - boils new battery - puts out over 17 volts. Alternator or Voltage Regulator (or one unit?) Thanks! ---

The alternator has an internal voltage regulator. So the alternator requires replacement. Tester ---

Unless the battery is real new it may be wise to replace that along with the alternator. This should keep you going for a long time without trouble.
