Question capacitors storage

[and77man]

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??

Do these conditions affect the interval (days or months or years) to repeat the procedure of energizing stored devices without risk of deformation of the dielectric layers in aluminum electrolytic capacitors and causing permanent damage from disuse in these capacitors?

No.

There will however be a higher chance of physical degradation & likelihood of mould growth due to the elevated temperature and humidity.

Long term storage should be at less than 25' and less than 50% humidity. That applies to media such as tapes or cassettes as well.

In my case, given my humidity, temperature and age of the devices, what is the recommendation? For me, it is impossible to keep it at 25C 50%

Use big plastic zip bags and add desiccant packs.

Yes, I tried, but moisture always got into the closed bags and the silica gel became saturated, so I stopped using it. This type of protection is very complex.

Hi,

Plastic bags are not entirely nonporous. They make poor barriers for keeping things in or out of them. They work to a certain degree but over time they still leak.

What is usually used for keeping moisture or air out entirely is either the use of a potting compound of some type, or to hermetically seal it inside an appropriate envelope. You could look that stuff up for more information.
