When you take the battery apart, you'll find 6 AAAA batteries-which are normally expensive.

Yeah... for all those devices I have that use AAAA batteries.

It would be interesting to keep one of the AAAA batteries in there to charge up a capacitor and shock anyone who tried to take the money out. Just an idea...

It probably wouldn't be much of a shock. A single AAAA battery would probably just give someone a mild tingle, nothing really unpleasant. It would also be a dead give away that the battery is hiding something

Note that he said "to charge up a capacitor", 1.5V would give an un-noticeable shock, but by using it to charge a capacitor, 1.5V can become many hundreds.

Remember, thieves look almost everywhere
Reply 12 years ago on Introduction

You could even use a good 9V battery. Remove the two rod-shaped objects on the inside (and don't mix them up, or you've got problems) and fold the banknotes in half. Wrap them around the rod things and put them back in! Ta Da! Warning: Battery could leak or explode (be careful).

WARNING: Your money could also burst into flames

So, I guess it would be best to use a dead one then... Or just spend the money.

I got a photo of the inside of a battery with bricks wrapped together in a plastic film. It's not a great photo but you should be able to make out the bricks. I think (I'm not sure) they're used in those cheaper batteries because they're probably cheaper to make than 6 AAAA batteries.
