Wacky.
Do you know what it was? If I recall correctly these caps aren't 
electrolytic even. Some sort of carbon material. Their ESR probably sucks 
ass, but for what you'd use them for that wouldn't matter at all.

OT (sort of) Question to (electro-)chemists out there:
Is a Farad equal to the number of electrons that would correspond to one 
Mole of hydrogen (protons)?
Like a quantity of electrons equal to Avogadro's number (which is a big 
number).

If so then 60 Farads would be able to electrolyse 15 moles of hydrogen 
(gas - H2) which given hydrogen's molar gas volume of 25L, would be 375L of 
hydrogen gas at atmospheric pressure. (Sorry I had a college flashback)
