Aluminum electrolytic capacitors

[lucas88]

I have stored here electronic devices with aluminum electrolytic capacitors used and manufactured in the early 90s. Here the temperature varies between 33-36C RH: 57-67% without rain in my home. These electronic devices need to be energized what maximum interval time for energize all electronics in 220v to prevent failures in these aluminum electrolytic capacitors caused by disuse?

Please stop; changing your username is not going to change the answers you've gotten in the past. As discussed before, the electrolytics dry out; energizing them does not stop that.

Here My home city Brazil IS 220 AC 60hz I have stored here electronic devices with aluminum electrolytic capacitors used and manufactured in the early 90s. Here the temperature varies between 33-36C RH: 57-67% without rain in my hom I know that these aluminum electrolytic capacitors and electronic devices are old and I can't do anything to make them look like new again with factory specifications and open all the electronic devices, desolder all the aluminum electrolytic capacitors, reform them, resolder these capacitors, close the devices is complex and careful work I would just like to keep them in their current state for as long as possible because electronic devices work normally today but I read that if they remain unused for many years when turned on they can have serious problems so I would like to find the maximum interval to energize these devices for 30 minutes to 1 hour
