HF has an extremely acrid, bitter smell.... its hard to describe because you don't come across in at all... in vapor form its a white. if you were exposed to it it would be an experience you wouldn't forget IF you managed to survive it.
Possible HF exposure would be one of a list of concerns if one of these blow up on you... the electrolytes can contain some nasty things like phosphates, arsenic, or perchlorates... and don't forget the metallic lithium which itself is highly toxic. Basically, if the casing breaches, get the hell out of the area!
In short, dont mess with batteries :P
Lithium ion batteries don't contain metallic lithium, unless they are SEVERELY over discharged, but when they are over discharged to that degree, the bulge.
I'm happy with my NiMH batteries, much safer to use.
