You might have gotten rid of the batteries by now, but in case you haven't yet, I'll offer a suggestion. Get a box, or better yet, one of those big bags of baking soda. Keeping soda handy is a good idea any time we have to handle the batteries, along with a gallon or so of water. Also, wear clothes you can throw away, because regardless of how careful you are, somehow holes always seem to show up after the laundry is done. Eye protection is a good idea. I had a battery turn over in a boat and the acid soaked the indoor/outdoor carpet. I neutralized it with soda along with plenty of water and wallah
No damage! That hydrochloric acid is nasty stuff! I think I spelled it right.
