that would basically be like a e cigarette battery exploding
Not true, it would be much, much more impossible than that. Lithium batteries are both much more unstable and much more energy dense than usual 9V batteries, it’s quite literally impossible to kill someone with a 9V battery explosion unless it’s being held inside the mouth or something. There’s definitely some explosive in the pager
Edit: this comment has assumed 9V pagers
Those two statements are in the same phrase… My god
