[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]It has nothing to do with the elevator.  The battery was defective and starting to fail.

Li-ion batteries are, in fact, quite dangerous.  The big issue is that they cannot be extinguished once they start to burn, so they will always burn completely (which is why airlines limit the size of Li-ion batteries that can be used in laptops and other devices that are taken on planes).  Definitely check anything that you own that has one of these batteries periodically and treat it as hazardous waste if the battery starts to bulge (a sign of imminent failure).  Also, don't buy cheap no-name batteries from Aliexpress (etc.), since they often lack the safety protections necessary to prevent thermal runaway.[/quote]

Lithium ion batteries are not “actually quite dangerous”.  There are billions and billions of these on earth.  A very small fraction of them catch on fire or explode.  Unless you’re going to say electrical outlets are “actually quite dangerous”, it’s really not a fair representation. [/quote]

To put this into perspective, [b]there are about 3,000 residential fires per year from extension cords. [/b]Extension cords are "actually quite dangerous."

Lithium ion batteries caused 1500 fires between 2014 and 2018.

Which is more dangerous here? Also, you probably have more batteries than extension cords in your home.[/quote]

Never heard of that. Got a legit source? Sounds scammy. [/quote]

I got it from the CPSC. I think they are in the pocket of Big Outlet though.
