I have done a lot of reading up on this situation and have seen a lot of posts and opinions about the alternator and the battery. My deal is, I just got a new battery and two new alternators (because one was bad when I bought it) about two months ago. And I have had this problem a couple of years ago where I also replaced them both because, whatever the problem was, caused my battery to explode (boil over). Again, only a couple months after replacing them. I would like to know what could cause this to repeatedly keep happening. Maybe a bad computer? A certain connection? My belt? This is a 2005 mercury montego. Any advise is greatly appreciated

Bad alternator, bad ground, corroded cables, short in the starter/soleniod. You have to get a gameplan and a good multimeter and probably an extra set of hands and track it down. Start with the battery and the alt and go from there. There were some really good youtube videos about chasing electrical problems
it is not your computer. the reman alternators are notorious for being terrible quality and don't last long. the only ones I have had decent luck with are the NAPA lifetime warranty ones. but, as luigisho points out above, a bad ground or a short that comes and goes can wreck even the best voltage regulator, so you first need to make sure that the wiring is good.
just to make the point of how important this is, my red 94 was destroyed in a fire that started because the two large battery cables had rubbed together to the point of shorting out.
