Re the caps not lasting 25 years - get out your popcorn or look away immediately for what is to follow...
One thing some of the data about them doesn't show if they have ever been cycled? Whaaat? You mean like tiny batteries with an anode and a cathode, and some electrolyte? (Yeah, NO they aren't batteries but you see what I mean.)
Spending much of my life in broadcast, we have some good $$ gear with great caps. But those devices, once placed in a rack, may be turned on and NEVER turned off for 10-15 years until a power-reconfiguration makes it mandatory. Some don't make it past a power-cycle, so we have to have an exact functional spare standing by.
So what is happening here? The caps,even though good, are only charged once, and sit at a steady-state full charge for a decade or more. They go high ESR. Functional while on, but due to lack of any chemical cycling, you can bet some won't recover from a power cycle.
The EXACT same unit, one that has been turned on and off or used temporarily for other projects, survives. Basically the caps were kept healthy by allowing them to charge and discharge from normal power cycling once in a blue moon. Doesn't take much. And no, I didn't keep a recorded schedule like I'm trying to take care of FLA's.
I know - sounds absolutely ridiculous, but that's been my experience.
