New battery will run down over night and have checked to make sure nothing is on on 2001 Buick LeSabre

Battery replaced but the LeSabre will not start the next morning unless jumped. Nothing is left on. Alternator is working so i know it is charging when running.

The battery still could be bad, have it load tested to make sure. Parasitic draw test would be another opinion.

I had the same problem with mine...turned out it was the air shocks on the car. they were leaking which was causing the air pump to run constantly in turn running the battery down. I would check that.

Have you checked at night to see if there is a trunk, interior light or glove box light on?
