Battery relocation- Does anyone know of an actual hydrogen sulfide explosion incident?

I had a battery going bad, dead cell in the morning, but if i charged it good, it would work all day.
Sitting with it in a gas station after putting gas in, i tried to start it. The battery blew up, LOUD bang.
The cop who was pulling out of the station, jumped out of his car and pointed his gun at me.
So did the gas station attendant.
I guess the blown open hood kept them from shooting me.....
