Why is the battery light still on after a battery change?

Replaced battery (under warranty, appeared to have one cell bad) but still doing it. Drove to the parts store, pulled the alternator out in the parking lot (could do it in about 5 minutes by now) and brought it in and tested it while hot, it failed.

Is the battery still on after a new battery?

I chanced it when I needed a new alternator, I got a new alternator from Advance Auto, their Carquest 130 amp one, and it is working fine so far, but has a lifetime warranty.

Why is the battery light on on my 4.6L?
