How It’s Made: Tour Of AA Battery Factory

This is a tour detailing the process in which zinc-carbon AA batteries are manufactured at a Chinese factory, which can produce up to 500,000 batteries a day. That’s a lot of batteries! And what percentage of those do you think end up in a person’s butt? My guess is the number might surprise you. That number would not surprise me though, because I assume everybody is walking around with a buttful of batteries. And not just AA’s either, 9V and D’s too.

Keep going for the video, and be sure to leave the captions on for an explanation of what’s happening during each step of the process.
