Paul:

Thanks for posting that link here, folks need to see this.

When you say "leakage" do you mean of the electrolyte (which we are told is highly poisonous) or just electrical leakage?

You are gonna have fun with that cap Paul.

It was charged to a bit over 0.4 volts, and so far it's decaying at a very slow rate. So at least the bcap isn't broken. The datasheet shows a typical leakage current of 1.5mA @ 25C after the cap has rested 72 hours.

To be honest, I'm afraid of this cap. It's hard to believe that when fully charged it contains more energy than a AA battery!  Have you seen what happens when small electrolytic caps short internally? What would this thing do?  It's a bomb. Hey, that would make a nice Mythbuster TV episode.

thank you for that statement above .You will be amazed what this  does and i see you are being very critical . that is good information and is adding positive information we can all use . also i appreciate your math skills  and this one as well:" Bill, Thanks. Stefan's correct that Dr. Stiffler has mentioned this odd effect. If true then you guys made the discovery of all discoveries."
and this one "in that article, it seems like they are assuming the cause is ESR, but I can't see that being the cause because these caps have extremely low ESR, not high, which is evident by the fact (according to the datasheet) that the short circuit current is 3500 amps!  2.7V / 3500A = 0.77 ohms, which is in agreement with the datasheet ESR

Please test it to death and you are right i got this from the manufacture , a friend there . if you charge this cap above 2. 8 volts the cap will start to swell and fire off the screw so look out for the aluminum bullet ! As long as you are being objective  i think you will  find something out very  very interesting that i discovered . O.............K

we appreciate that

you know paul thats the hardest i laughted .. in a long time ...  i made it to the to be honest part and i broke out laughing ...  ok to be honest there were aa few more giggles b4 that but then you got the thing a your afraid of it ....  lamo  lol 

mymymy



enjoy..

w

its not a bomb....    its the boom  lmao still.....
ya know as in the FREE ENGERY BOOM...

i herd someone talking bout a rail gun there ya go ....  lol   the cap plugg

perfect myth busters deal ... its about there speed! 

[kooler]

sweet,
i am going to get me one to see what happens during the boom
this is starting to sound kool...
with my current setup i think i could charge this beast in less then a hour
seeing how i can charge a 150uf 450v cap in a few seconds
then boom
maybe even a emp boom..hahahahaha
nah

oh, god  i can't wait
