When you take the battery apart, you'll find 6 AAAA batteries-which are normally expensive.
dfault312 in reply to dll932May 19, 2006. 2:06 PM
Yeah... for all those devices I have that use AAAA batteries.
stonehenge360 in reply to dfault312Aug 21, 2006. 3:07 PM
most new lazer pointers take AAAA batteries

Also Streamlight Stylus flashlights-which we have dozens of where I work for inspection.

thats creative. but i just keep my money in a mini m & m container. (very inconspicuous). i keep it in a box of lots of random stuff.

But what if the thief wants some M&Ms? :O
bombmaker2 in reply to iwantacuracyJan 28, 2009. 1:09 PM
Remember, thieves look almost everywhere
bobwantzanapple in reply to bombmaker2Jun 1, 2009. 2:29 PM
yes, but will they look into a m&m case? if they rob ur house, they'll know to check the 9v batteries.
bombmaker2 in reply to bobwantzanappleJun 1, 2009. 3:12 PM
only if there on this site all the time
jimtran93 in reply to bombmaker2Jun 16, 2009. 8:38 PM
hahahaha

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
eyebot117 in reply to bobwantzanappleJun 22, 2009. 10:16 PM
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.

ya, they're bargain store brand batteries,
sgt.paper in reply to harry hardcore hoedownJul 7, 2007. 12:22 PM
i had a green one and it burnt my skin
Junkyard John says: May 14, 2006. 1:32 PM
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...
bobwantzanapple in reply to Junkyard JohnJun 1, 2009. 2:31 PM
genius!
Yerboogieman in reply to Junkyard JohnJul 10, 2007. 5:02 PM
send me something on how to do that.....
RUBiksCUbe in reply to Junkyard JohnAug 17, 2006. 12:44 PM
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
Pie Ninja in reply to RUBiksCUbeDec 2, 2009. 1:23 AM
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.

is this dangorus?
lkik says: Dec 15, 2008. 3:36 AM
good until some one finds the battery and trys to use it so they throw it out
dancingal101 says: Oct 11, 2008. 8:17 PM
Nice idea. Who would think of looking in a freakin battery for money? Only thing is, how do you make sure nobody throws the dead battery out?
Von Klaus says: Jul 10, 2006. 8:25 AM
what about someone testing the battery (by licking it). he/she says it is dead and tosses it away?
gameboy7oa in reply to Von KlausJul 31, 2007. 9:34 PM
hahaha that reminded me of a time of playing truth or dare in a basement. my girlfriend decided to dare me to lick a 9 volt didnt end good for me
mrtools (author) in reply to Von KlausJul 17, 2006. 3:52 PM
thats why its easier to put it in something so they dont
andy60 says: Jul 26, 2007. 2:58 AM
nice idea, but i would most definitley forget it was in the battery lol
hack124x768 says: Aug 25, 2006. 8:33 PM
About the "Battery Virus", It is possible for laptop computers. Most all Li-ion laptop batteries have a microcontroler built in for monitoring the voltage of the cells and cut off power when nessicary to keep them from going flat dead when in use, or exploding when charging (those suckers are freaky). It could be possible to load one's own code to that chip if it was a flash rom instead of a normal rom. If you are a windows user, look in your device manager and you will see your laptop's battery, that should be proof enough. Nice idea for the safe, btw. --Andrew
Yerboogieman in reply to hack124x768Jul 10, 2007. 5:00 PM
have you ever seen the movie bicentennial man cause you called yourself one and your name is Andrew. thats kool "be possible to load one's own"
Yerboogieman in reply to YerboogiemanJul 10, 2007. 5:02 PM
the robot on that movie is named Andrew and calls himself one
hack124x768 in reply to YerboogiemanJul 10, 2007. 11:51 PM
Yes, It's a good movie. I rarely call myself one, unless I'm in character or something.
klee27x says: May 15, 2006. 4:10 AM
Wow. This looks like a great way to lose your money.
Yerboogieman in reply to klee27xJul 10, 2007. 5:05 PM
keep it in your project box
hjjhjhgjjh in reply to klee27xJun 23, 2006. 4:50 PM
HAHA I agree in two days ill be like what is this trash and throw it out.
Trimaster says: Apr 15, 2007. 8:54 PM
i bet i would throw it away by accident XD
eviloverlord says: May 18, 2006. 11:56 AM
No they don't - it's a single battery of six 1.5V cells. A battery is a collection of cells.
mrtools (author) in reply to eviloverlordDec 8, 2006. 11:24 AM
that's correct. but they can be used as batteries if you want.
aforsberg in reply to eviloverlordDec 6, 2006. 4:23 PM
dude, stop being a grammar prick.
