electrolytic capacitor truth or myth?
classicsamus87:
What do manufacturers say about electrolytic capacitors going unused for a long time? a person told me to use all my electrolytic capacitors that have electrolytic capacitors at least once a month for at least 30 minutes otherwise the electrolytic capacitors depolarize and lose capacitance, is this information true? is there a correct interval or not to energize the electrolytic capacitors and preserve them?

I've used all kinds of electronic equipment over many decades that often have gone unused for years. With one exception, I've never had a failure because of bad polarized capacitor.
As for what manufacturers say, see page 18 of this https://www.nichicon.co.jp/english/products/pdf/aluminum.pdf

I didn't understand why they gave me information that I need to use electrolytics every month. I have electronics with old and new electrolytic capacitors.

I suspected such. I was going to suggest I just plug my old electronics in backwards so I can back-flush those pesky capacitors. :)
