Battery Fumes - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So, when driving yesterday I noticed a smell of rotten eggs... thought it may be coming from the vents... couldnt figure it out. After stopping and sniffing my engine bay, i notice my batter is fuming out of one of the 2 vents on the top of the bat (made me feel great that I was sniffing in gaseous sulfuric acid)...the battery was very hot to the touch. I do not know when it was last replaced, but looks newer and the truck starts right up, even after this issue/ cooldown. The weather was 60 F, and I wasnt driving hard or for very long. I have never seen or heard of this before, but saw there is one other post, and the rust issues in this location it must not be all that uncommon?

Who else has had this happen? What should I do? What other problems may have led to this happening?
