I've heard battery acid completely ruins it. However, how would anyone get battery acid on their gear?

By storing their climbing gear in a garage or pickup conversion...
Even the fumes from a lead-acid battery in an enclosed space can damage nylon. Bleach is another culprit.
I have done a little bit of bleach testing on nylon, and it seems that bleach does not really affect nylon, at least not in the short term. As far as fumes go, I would have to say no to that too, but I have not actually tested it. The issue with battery acid is that it contains sulfuric acid and SA will damage nylon. However, when an automotive battery is charging, the majority of the "fumes" that come out is hydrogen. Sulfuric acid does not really evaporate, that is the reason why you add water to a low battery and not battery acid. Battery acid is part water part SA, but only the water evaporates.
