P-suv kills woman driver by H2S from battery
 

Hydrogen sulfide inhalation killed mother, toddler found on Florida's Turnpike in June - Orlando Sentinel

I have never heard of a battery killing a driver by out gasing H2S

Wrong battery? More like over charging?

My voltage regulator on my 911 cooked a battery. I had to abandoned ship the odor was so bad

Yep, a battery mounted in an unvented space isn't good design...but it's done all too often.

Heck mine was out of the passenger compartment

I couldn't imagine sitting on a cooking battery long enough to be killed?

I had one overcharge in my SC years ago and Wayner is right, the fumes/odor were so bad, it made me choke for air a few times before I got where i was going to figure it out.

The battery on a Cayenne is in a vented space. A hose connects to the side of battery to dump any H2S under car. One must be mindful to put the plug cap on the other end of the battery where you aren't using a hose.

Don't buy it, more likely carbon monoxide

''Unlikely, the effects are different; carbon monoxide causes suffocation by bonding with hemoglobin while hydrogen sulphide is broad-spectrum poison that mainly effects the nervous system. It also corrodes metals like copper leaving a noticeable clue for investigators.

Hydrogen sulphide is far more toxic; a few minutes exposure to 500ppm is around 50% lethal (as well as causing severe eye irritation and some permanent damage; it'll also not be noticeable as the olfactory nerve is rapidly paralysed by exposure to concentrations over 100ppm), while a human can breathe 1,200ppm carbon monoxide for more than an hour with little danger of death and even 2,000ppm wouldn't cause 50% fatalities.
1,000ppm hydrogen sulphide will incapacitate in seconds and cause rapid death; it is actually more dangerous than hydrogen cyanide.''

Something that is frequently neglected. It's also tempting to purchase a cheaper unvented battery that is similarly sized.

I've managed to evacuate more than a few SUV's in my day, wherein the other passengers opined that had they stayed, the odor may well have killed them.

Drinking Point beer???

this endless quest for hyper efficient autos is going to kill us all!!!!!!

AAAAHHHHHHHH!!!!!!!! (runs away screaming and waiving hands wildly)
