Just like the LI batteries in your garage right now for all your battery powered devices. I guess you best go remove and toss away everything you own with a rechargeable non lead acid battery :poke: Oh wait they blow up some times too... (happened to me while starting a 91 Ford E 250 from inside the cabin while just turning the key)
Li gets a bad rap. Its not perfect and it gets sensationalized in the media when ever there is a fire, unlike the more plentiful gas and diesel fires.
