Put a new alternator in a car with a low charge/deadish battery? Cause I just changed my alternator out(confirmed it was bad at Autozone) Put the new one in the car but then my father told me doing that can be bad for a new alternator. What gives? Im currently charging my battery now.

Alternators charge batteries.......it can't hurt the alternator to ask it to do its job. My friend started his car with a friends battery in Daytona at college, took it out after the engine was started and gave it back to him, (didn't have jumper cables), then drove to Tampa with no battery in the car, just alternator powering everything. People say thats bad too, not in his case......... (pretty sure he took the battery out anyway, can;'t remember for sure, either way, his battery was completely fried)
Many times over the years I've left headlight on or whatever and drained the battery dead. Got a jump start and drove off right away. Letting the alternator charge the battery while I drive....never had a problem at all with the alternators.

I was looking at alternators on Advance Auto and came across a alternator that said " INSTALLATION ALERT! This alternator will overheat if installed with a battery that is not fully charged." http://shop.advanceautoparts.com/web...S_538998090___

Yeah, if you have a stone dead battery it can do that. You end up with the alternator either at or very near max output for too long. Alt's have a max rating, but that doesn't mean that they can produce max forever without overheating. They aren't rated for 100% duty cycle.
