It could either be because your alterneator is going bad, or that your alternator belt is loose. Theres an component in the alternator that sends a signal to the dashboard for the battery status. Most often on reconditioned alternators, this component goes bad but it does not affect the overall performance of the alternator

Very confusing question. I assume you mean what light comes on when the batteries is defective. If that is the case then the red battery warning or charging system warning light may come on. And then again the light may not come on at all. The light is there to warn you about a problem with the charging system and not necessarily with the battery.
