When you pull something apart to find...

Everyone has something they have pulled to bits, the find the inside is a disaster or just not at all what you expected.

Here is one I got today, was free for those wondering.
Oh this looks interesting, a battery pack in the leather pouch.



Seriously, they make lead acid batteries in this size and shape ?




I'd already pulled apart the electronics this connected to, was a real hatchet job.

Haha. Is that someone else's DIY project?

That is certainly different.

After some searching i came along this website that still sells them.

They say it can be used for a alarm system.
