Hydrogensagas

I don't think it's overwarned at all. Hydrogen is explosive, no doubt about it. 2% sounds like an insignificant number, but if you happen to be on the short side of the equation it will be pretty significant. It reminds me of the guy riding his snowmobile on Lake Hopatcong by me a few days ago. It's been seriously cold here for weeks, yet he managed to find a place where the ice was thin. All they've found so far is his helmet. Or riding a cycle on the street. 99% of the time cars see you coming and don't turn in front of you. It's that 1% that kills you.

If you ignite the hydrogen issuing from a charging battery, will it blow the battery apart?

Not necessarily.

It will depend entirely on the mixture of air/hydrogen above and around the battery, as well as the rate of charge/development of hydrogen, and subjec to the liquid level inside the battery, the space inside the battery .

Or the external ignition may follow the hydrogen stream to its source and pop inside the battery, thereby creating an intense pressure that drives the liquid sulphuric acid through the vent holes in the caps. The acid exits in a fine spray that will burn anything it touches.

It is especially effective on eyes.


Been there. Done that. Effectively blind for three weeks.

Batteries deserve respect.

batteries and lighters

An old (and stupid!) friend used a lighter to check the electrolyte level in his car battery, which blew up in his face. Luckily, he can see today, but the acid burns on his face pretty much mask the acne scars from when he was a kid,
