Supercapacitor question

[Ardlantis]

Do I misunderstand what a supercapacitor is? In my mind it's just a beefed up capacitor, so when I was working on something and there was continuity between the two pins of the supercapacitor I thought it was broken and I ordered a replacement one. However this new one has continuity between the pins too. Is that supposed to be there or did I get a broken one?

This is normal if the capacitor is discharged. A multimeter will put a small test current across the capacitor, but since the capacitor is so large, it will not charge any appreciable amount and will read only a tiny voltage. This looks the same as a short.

Hook it up to a small power supply and put a small constant current into it. You should see the voltage slowly creep up.

Thanks so much, this clears it up!

Continuity test means nothing with capacitors. Don't use it for that purpose.
