The reason we don’t see exploding battery attacks more often is not because it’s technically hard, it’s because the erosion of public trust in everyday things isn’t worth it. (www.bunniestudios.com)

edit: after 20 comments, i'm adding a post description here, since most of the commenters so far appear not to be reading the article:

This is about how surprisingly cheap it is (eg $15,000) to buy a complete production line to be able to manufacture batteries with a layer of nearly-undetectable explosives inside of them, which can be triggered by off-the-shelf devices with only their firmware modified.

screenshot of paragraph from the article saying "The process to build such batteries is well understood and documented. Here is an excerpt from one vendor’s site promising to sell the equipment to build batteries in limited quantities (tens-to-hundreds per batch) for as little as $15,000:" followed by a screenshot of "Flow-chart of Pouch Cell Lab-scale Fabrication" showing a 20 step process

Did you read it?

The article literally talks about inserting an explosive layer inside the battery at production. Just like the comment said.

It isn’t “any batteries can explode”.

Reports indicate the explosive payload in the cells is made of PETN.

Such a sheet could be inserted into the battery fold-and-stack process, after the first fold is made (or, with some effort, perhaps PETN could be incorporated into the spacer polymer itself – but let’s assume for now it’s just a drop-in sheet, which is easy to execute and likely effective)

Just to be clear, the pager thing wasn’t exploding batteries, they had apparently been modified at the production level to have explosives in them, which could be triggered by the pager system itself.

What? 🤦 The comment I replied to said:

Just to be clear, the pager thing wasn’t exploding batteries, they had apparently been modified at the production level to have explosives in them, which could be triggered by the pager system itself.

It seems clear that "they had apparently been modified at the production level" is referring to the pagers, rather than their batteries. But the article is explaining how it could have been that the batteries were the part of the pager that had the explosives (in which case it was the battery that was exploding).

You are inferring what someone meant, and then applying some super pedantic reasoning.

When manufacturing pagers, that includes the pager electronics, the case, and the battery.

Wasn’t exploding batteries

The batteries themselves unmodified, standard batteries were not somehow hacked to explode. At some point in the manufacturing of the pagers which includes the battery, explosives were included.

I think I am inferring correctly, especially since the person you're talking about replied "of course not" to my question about if they read the article.

alrighty then. Dig your heels in.

i encourage you to re-read the original comment in this thread after reading the article 😂

You should do the same.

(@[email protected]:) Just to be clear, the pager thing wasn’t exploding batteries, they had apparently been modified at the production level to have explosives in them, which could be triggered by the pager system itself.

(me:) Did you read the article? It sounds like you didn’t.

(you:) The article literally talks about inserting an explosive layer inside the battery at production. Just like the comment said.

I am really curious: can you tell me, do you actually think the first commenter in fact read the article and was agreeing with its suggestion that the batteries could have been manufactured with explosives inside of them?

(you): It isn’t “any batteries can explode”.

Nobody claimed that, but in retrospect I guess I can see how, read alone, the pull quote I selected from the article to be the title of this post could be interpreted that way.

Delete this entire post or shut up, bro. You’re being nuked with downvotes.
