Long-term Capacitor storage questions

[augustaa88]

where I live, the temperature varies between 33-35C and humidity ranges from 57-67% without rain, and I have electronic devices manufactured in the early 90s. What is the maximum possible interval for me to energize these all devices and for at least how many minutes to prevent failures in the aluminum electrolytic capacitors caused due to disuse??

This is a bit of a troll like question.

If you can keep the devices turned off for 100 years, you will never have a problem with the electrolytic capacitors drying out.

If you turn the equipment on when you need it, you may sometimes have to replace one or more electrolytics. You will have to replace an electrolytic capacitor now and then anyhow, even if you turn it on sometimes.

The temperature that is important is that of the capacitor, not your temperature. Also, the service life can vary by an order of magnitude depending on design characteristics. Another point is the reputation of the manufacturer and the quality of the components they use. Your devices are about 30 years old, and not knowing how long they were used is anybody's guess on what life is left.

Your instincts are good. Turns out this is a sockpuppet of a banned member who keeps asking this type of question here (over and over and over...). This version of him is no longer here, so I'll close off this thread.
