Cornell Dubilier caps- date and condition

[Wes]

Whelp, I thought I was gettin' a deal..... I got some reasonably priced Cornell Dubilier 'lectros for some old solid state gear
with beefcake power supplies. They arrived and I immediately noticed that they looked a little rough. They are scuffed up,
one has a tear in the outer insulation, and several of them have minor dents; looks like they were thrown around in boxes....

Looks like the manufacturer code business is: 658-9533-845

CDE must be 658, right?

Is the year and week the 845 with 8 being, 2008, 1998, 1988 etc?

I'm not really worried about the scuffs, I can cover the insulation tear (I'm not using them in a negative supply anyway), but the minor dents and the age have me a little concerned.

I got them here:

400R392U100AC8 CDE capacitor 3,900uF 100V Aluminum Electrolytic Large Can Computer Grade 2020001613



Should I stay away from the deals down at the lot?

The dents have probably misshapen the inner foil.

At 100 Vdc, I would not use them.

That's what I was fearing. Thank you.

The least abused of the CDE caps you've purchased might come back (if old) by carefully forming them.

Vintage caps are often not a bargain, nice new fresh caps from UCC, Nichicon and Panasonic are about $5 each at Mouser, at these ratings (3900uF/100V)

I would expect 9533 to be the date code, 33rd week of 1995. So 20 years old.
