I need some help. Someone tell me what happened.

I get another FM 9AA to 3D adapter in the mail today. I've already bought another set of Eneloops for it. I put the batteries in, MAKING SURE THE POSITIVES AND NEGATIVE ARE THE WAY THEY'RE SUPPOSE TO BE. Not 30 seconds later, the batteries are smoking and now are completely burned.
(I tried to save them, but the adapter got so hot I could barely touch it even while using a towel.)

You should make sure the pin at the top of the adaptor is straight and not touching the walls. When I got mine it was bent and touching good thing I noticed right way.

Good thought. I would think the charging socket is the most likely location of a short.

I'm thinking it must be one of the batteries. I just put in a set of Energizer 2500's and there doesn't seem to be any abnormal reaction happening.

BTW, I checked the pin, while not straight, it isn't touching the walls.

Hmm, I don't know, I'd still keep a close eye on it. Even if you had a bad cell, it shouldn't have cooked like that unless something was completing the circuit. I love my FM holder, but there isn't alot of tolerance in those charging adapters. If you unscrew it and look at the inside of it, you can check to see if maybe there's a loose blob of solder or something that could have shifted and shorted it and might shift again.
On the other hand, was it in a light or plugged into a charger when this happened? If that's the case, it could be a whole different story.

Nope, I had JUST put the batteries in it, so it wasn't in a charger or light yet. I'll take a closer look at it when I get a little more time.
