"SOLD" Wanted: Ultracapacitors used

[Inverted18650]

Looking for used: 2.5/2.7/3.0V DC ultra capacitors. 2600-3000F. Not interested in the eBay gamble. Looking for quality, not more than a year or two old, 20 caps total. Used at a decent price. TN, USA. Thank you.

used ones might be unusable... if they were usable they would be still in their original location in some device serving it's function ESR goes up on those at the end of life.. so even if you manage to buy used ones the ESR will be way too high rendering those supercaps "unusable". if your ESR requirement is not critical then look after bigger LiPo packs for RC models, those have ESR in the miliohms range (approx 10mohm) a typical 3kF supercap is slightly less than 1 miliohm, but the used one will be much higher. if you go for lipos then be aware of fire hazard - lipo might catch fire on dead-short (supercap will not).

Occasionally people have been known to buy items for a project and not get around to it, or conduct some testing and change their mind, you know, normal human stuff. That's what I'm seeking. Not silly replies about characteristics that I am fully aware of.

Blimey! How to pop up on a forum out of the blue and make lots of friends...

I thought it was an attempt at being helpful, particularly seeing as how you think everyone is psychic and thus knows your intimate history the very day you turn up. Still, I'm sure you'll benefit from no-one bothering to give you the time of day in future since you'll obviously already know everything there is to know about it

no more silly replies i promise  

just this one:
a 3kF super cap is something like 70-80 euros a pop.. 20 of them is approx 1500Euros... isn't the assumption that someone spent 1500Eur on parts, never used them and will sell them for a fraction of the original price simply silly ?

Thank you,

Rob,

Why do you assume I would offer a fraction of the price? Why can't I buy used from people who just don't want them and pay fair value so they have their cash back and keep the money in the "community" instead of buying them new and giving the cash to the corporations?

Its the exact same reason I bought the EEV Blog DMM when I have a couple Fluke's. You keep the money in the community and thank the guys and gals who make this possible.

Not everyone looking for used equipment is cheap, not every "newbie" is new to electronics, and not every glass is half-empty.

I am a half-full guy and hope you can be some day as well. Having such a negative attitude is really a drag.
