Got myself some capacitors for $10 apiece.

The specs are 22 kV, 1 uF, discharge capacitor. See

The seller was wrong in describing them as 22 VOLT capacitors. They
are 22 KILO volt capacitors. (the seller is Fermilab).
They are similar to this one:

but have twice more capacitance.
Anyway, here is my question. I have a 9 kV DC power supply. (a
Franceformer). How can I safely test these caps before selling
them. At 22 kV, they can store about as much energy as a .22 bullet,
according to my calculations.
It would be less at 9 kV, but still, obviously, very deadly.
So. What is a safe way to charge them, verify that they hold the
charge, and then DIScharge them at 9 kV.

Are you sure your Franceformer produces DC? Most of them are AC, as
for neon signs and oil ignitors.
