Supercharged 9 Volt Battery!!!





Introduction: Supercharged 9 Volt Battery!!!

About: I live in a small town where anything can happen! ESPECIALLY IN MY NEIGHBORHOOD!

Scare the crap out of your friends with this new "supercharged" 9 volt battery!! WARNING: If you have a pace maker or are dependent on any other electronic device for life support do not touch this battery!!!! also i am not responsible for ANYTHING stupid you do with this including but not limited to loss of life or loss of property due to 1 hell of a jolt!
ALSO make sure the capacitor is discharged before you go messing with it

Step 1: Parts!!!!

2 9volt batteries!
1 soldering iron w/ soldier
1 hot glue gun w/ hot glue
1 16v 3300uF capacitor
common sense

Step 2: Taking Apart the Battery.

All you have to do is bend the metal flaps on top of the battery and lift out the top part you can throw the insides and the little cardboard thingy @ the top!!!! not the bottom!

Step 3: Soldier and Make Sure the Wires Dont Touch the Sides

NOTE AND A WARNING MAKE SURE THAT WHEN YOU SOLDIER YOU SOLDIER THE + TO THE + AND THE - TO THE - or you capacitor will EXPLODE!! ok now soldier the terminals to the + and - terminals of the battery on the other side ie where you cant see them (Note:bend the wires a little because the capacitor wont fit into the battery do as I do) now be sure the wires dont touch the sides then apply hot glue to the wires! put the capacitor into the case (after you coated the wires with hot glue) then add as much hot glue as possible then cover it up and seal it with hot glue to make sure it doesnt open! Your capacitor should look like this

Step 4: FINISHED!!!!!!!

Move on to step 5 for charging! NOTE at a GLANCE this looks like a 9 volt but with closer inspection it is actually a tazer A.K.A. a "supercharged" 9 volt battery!


when you charge it is also imperative that you touch the + to the + and the - to the - to avoid an explosion in your hand even though it may look like the perfect fit it should never be attempted i did this as a safety thing so you dont over charge the capacitor and cant get the battery off so you have to hold it there while it charges

to charge just apply the + to the + and the - to the - for a few seconds and let off then test it out on your cat or dog or wife or friend or husband (anyone who wont bit and or kill you if you try this on them)

Hope you enjoy this!!

    Will this actually shock you on your bare skin?

    So what ya charging it with? If you were concerned about it locking on, it would seam you are charging with another 9v battery? In that case, you can leave a 9v battery connected to a 33v cap indefinitely with no ill effect. Getting locked with the polarity reversed is likely to ruin the cap though; as they don't like reverse charges.

    uhm.. i made this and i think i put the -to the+ and i used it before reading this and it worked just fine for me... but maybe it explodes on the 5th or6th time or something so someone help!!! i dont want to use it if its gonna explode and i dont want to waste it if it doesnt matter! aaaaahhhhhhhhhhhhh!

    exploding is the least of worries, i rigged it to blow and i got a pathetic little steam, i thought it was gunna go off like a grenade, they are designed for safety, if your capacitor has a cross carved into the end of it in the metal, instead of it exploding it will force steam out of this structurally flawed weakspot, its damn hard to find unsafe capacitors, i want a hand grenade ;(

    NOTE: I don't recommend trying anything in this post, if you want to see it try youtube =)

    Capacitors only explode impressively with voltages well above their rated maximum from my experience though I've never seen anything other than smoke, a big bang and a case flying around. Automotive bulbs though are very impressive with 230V AC though they cause glass to be propelled in all directions.

    why waste your time trying that when you could make one just by using gunpowder?

    It won't explode. At least not because of that. Just remember the polarity is opposite to what it should be and you should be fine.

    Would you be so kind as to upload more pictures of the case bursting open and battery acid spewing forth into your eyes and face?

    Its all healed up about now ;) if your talking about the 9 volt battery that i dismantled, there is no acid in there whatsoever. If the capacitor were to explode.....well im not sure what would happen.

    I'm sure this has been pointed out somewhere along the line, but the voice of reason seems to get drowned out all too often around here...

    A 3300-uF capacitor charged to 9 volts will store, at best: (0.5)(3300 uF)(9 V)^2 = 0.13Joules of usable energy.
    A typical 9-volt battery provides 10 to 20 thousand Joules of electrical energy over the course of its useful life. In other words, the original battery could have held over 100,000 times as much energy as the "supercharged" version.
    To give an idea of scale, running a small LED for 10 seconds might use up something on the order of 0.25 Joules, over twice what that capacitor can hold.

    For all intents and purposes, this "supercharged" creation is several orders of magnitude less dangerous -- and less useful -- than the original ordinary battery.
    Use your heads, people.

    it wont kill you. gosh. Unless, that is, you have a weak heart. Its 330 volt. at pracally no amps. In a way you can say volts do not kills, amps do. while, even at almost no amps... 11,000 volt WILL killl you.... 330 will not. please dont get me wrong... it hurts like crap still. hahah *note on the intstructable* You could just reverse the polarity of the capacitor in the battery casing to avaoid the whole "+to+ and -to-" thing. Cool idea.

    You can have a 100,000v van de graaf spark and not die from it.
    Its the current that kills you. If there isn't enough current flowing voltage won;t do anything.

    This definitely won't kill you, but it'd give a nasty jolt....

    It is true that its the current that kills you, but what most people don't know is that high current will certainly kill you but low current is also equally dangerous. Currents in range of 0.1 to 0.2 amp are supposed to be the most dangerous as they cause fibrillation, in common terms it causes the heart to beat irregularly and eventually causes a heart attack, and the heart stops beating even after the current is removed. This current range is known to interfere with the electrical pulses that control the heart muscles. Current ranges between 0.03 to 0.07 amps can cause breathing problems. So it is highly recommended that you test the current and not just the voltage output of these homemade toys before trying them out.

    and to think, that the whole 'contraction' comes from a very, very small area on the in latin, it's called atrium. it get's disturbed pretty easy.

    i know. i know twenty times more about the heart and kidneys than we should know for our exams. it's just so much fun to (constantly) correct the biology teacher (who knows only what's in our books, nothing more), because the schoolbooks aren't right all the time. and, it's very interesting, indeed!
