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

I finally got around to relocating my battery to the trunk. Obviously, I followed the instructions which called for a ventilation tube to prevent a buildup of hydrogen sulfide gas, which is generated when the system is charging the battery.

It got me thinking though. Does anyone know of an actual incident when somebody’s trunk exploded from improper ventilation?

I don’t doubt that it could happen but it also seems extraordinarily rare. This could be a symptom of everyone properly ventilating their system but something tells me that’s not the only reason cars aren’t exploding from H2S2.



Also, how long does hydrogen sulfide stick around? It makes me wonder if my old bench seat is an explosive hazard… :D
