If you get worried about hydrofluoric acid, put it in a polyethylene container. We used to keep lots of it in those containers, but it will eat through glass easily.
It, like most other toxic substances, is not bad to handle but you do need to take precautions and be safe. I have had several batteries of various chemistries outgas and 'bulge' on me in the past. Some leaked, most didn't. Anyway, when a battery is doing that it needs to be replaced. If it is an 'open' battery (like a car battery) it won't bulge, but the electrolytes need to be checked (typically add water to low cells so the electrolyte barely covers the plates plus a small safety factor. (For specifics, check the details for the battery you have.) Yes, I even had a NiCad battery explode on me (and it tore the bolted down top to the fiberglass case off). No one was near, and only a hole in the ceiling and an awful smell ensued. I still had to explain the hole in the ceiling of the garage where the case top went to my Dad ;-) ... Thankfully he was a engineer and a geek at heart too! I did use hydrofluoric acid at home in an experimental NMR I built in high school. The Fluoride in H2F is so active, it made it easy to detect with the home made (tube type) NMR. How to dispose of H2F? I just diluted it (an ounce of fairly strong per gallon of water and it went on the side yard where we put used motor oil after changing the car oil (all this 40+ years ago - The EPA would be all over folks if they thought they could do anything about what has happened in history).
