Question
Nissan frontier replaced battery and alternator battery goes down after driving at night what should be my next move truck is a 2000

Answer
Leon,

Check the output of the alternator and check to see if the wife to the battery, from the alternator is in good repair and connected correctly.  Next check the fuses for the battery/alternator to make sure it was not blown by the low battery the first time.  This would cause the battery not to charge.
