Re: Unused/New Electrolytic Shelf life

@ 999999999 + @ Th3_uN1Qu3:
Thank you gentlemen, for your dedication to a resolution. I thoroughly appreciate your efforts. As far as where I read that "not powering up will increase shelf life", it was 2+yrs back when I purchased them, and another 1-2 years back added to that in finding the information[??] that I used to make the purchase decision. I cannot remember the "source" of the info that stance came from. After re-investigating the issue, it appears you are correct, although, some manufacturers have trouble...

I have two electrolytic capacitors [ Sprague Powerlytic / 36DX / 95°C / 9800uF / 100VDC / 0905L 25 ] that I had shipped to me on 01-29-10 from Allied Electronics. They have never been used [powered up], and have been well taken care of in terms of temperature storage. They are replacement caps for the power supply block of a audio power amplifier, as the current ones are very leaky. My question is: In all that I have read, as long as electrolytic capacitors have never been powered up, they have a fairly long shelf life. Does anyone have information contrary to this?? Thank you in advance for...

Been a member ~2mos. now but never had a chance to get "started" [family elders--sorry]. I'm a 65+ yr/old R&D Lab Engineer {Ret.]--well, kinda...
Spent my youth experimenting with electronics, lots Heathkit test equipment, 5" scope from scratch, Geiger Counter [CK1026], my first home built "Hi-Fi" with Eico HF-12 and a Heathkit 7" R2R. Messed with transistors when a discrete device was a [big] pencil eraser--2N107/CK722/2N222--you get the drill.
