I’ve gotten battery acid over myself, but it wasn’t an earth-shaking, permanently disfiguring experience. I washed it off and can’t say I felt any permanent effects, other than skin that was a little dry. The guy’s a bit of a dipstick, but I’d say misdemeanor at best. Here’s an interwebs account of a similar exposure:
Yes battery acid didnt have any impact on the skin though it can damage your clothes.]
Maybe the perp did not want to do acid.
While I was serving as an artilleryman in Vietnam, we Marines still had the older cotton sateen utilities (fatigues, in army) and we had seen the new lighter weight Jungle Utilities on soldiers in Danang and we really craved having a set for ourselves.
Somehow, I managed to get a set of my own and they were cool and comfortable. Then while were conducting PMs on our gun section truck, its battery exploded and it doused me with battery acid.
The next second Im standing there in my underwear and boots and my brand-new Jungle Utes were completely gone! The acid didnt hurt me more than a mild sunburn but all I had left of my prized and hard-won uniform was a few green fragments.
