I just got a lot of power supplies and huge capacitors (8 * 37000 f) for free. That man told me the capacitors are a little dried out, but it's possible to reactivate them, does anyone know how I can realise that??

Thanks a lot.

Hi Hugobross.
I've heard a lot of stuff about capacitors, but when it comes to dried out capacitors, I've only heard one thing: Buy new ones, but since I've got some old ones as well as You do, it would please me if it's possible to bring them back to life.

Restoring electrolytics was the topic of another thread. Have a look at:

There are instructions at

What you do is that you basically set them up with limited current for about an hour.

Hey, thanks to all of you;
I'll try it out right know, if anyone has other ideas, just tell me..

best regards,

Mepco suggests heating the capacitor to its maximum rated temperature before re-forming.This helps to re-distribute the electrolyte.Charging current should be limited to about 10mA.
