No idea. I got it with the car (two years ago) and they never marked the date on the battery. I'm just wondering though if it being a bad battery would cause it to smoke. I am hesitant to put in another battery not knowing what the problem is.

Besides the battery, it could be a bad alternator (even though new) - have it checked at a different parts store. But it's hard to imagine either the alternator or the regulator making the battery smoke...

The alternator was tested before I bought it....I've gotten bad parts right out of the box so it's always good to check.

Sure once a battery, especially an old one, goes completely and utterly dead, it can easily be damaged internally by a re-charge. The plates inside can warp and short out.
 
Another possibility is that your starter motor is dragging and drawing HUGE amperage. A dragging starter can demand 400 amps! That'll smoke a battery for sure.
 
So I'd say battery or starter, not alternator or regulator.

Perhaps. The starter was replaced about a month ago though....

Replacement means nothing in diagnosis. That's how you get tripped up, assuming that a replaced part is good. You have to test everything in a proper diagnosis. A starter draw test isn't that hard to do if you have the right type of amp gauge (shunt type, NOT little voltmeter!!!).
 
Autozone could test your battery for a short using a load tester.
 
Remember, an old battery being completely and utterly drained is a death sentence for that battery.

And 2 years known plus who knows how long before is an old battery. As for the starter, the great thing with the slant 6 is being able to pull it in 5 minutes, have Autozone test it, and put it right back in (speaking from experience).

I misread the post the first time.
 
If the terminal smoked, check to make sure that it didn't damage the battery posts.
 
Also, check all connections. Check to make sure all positive and negative connections are good. That will make sure that part of the system is good.
