repairing a cap by refilling it...
MyHeadHz:
Is it possible to revive a cap by refilling it with electrolyte, like using a syringe? I know there is a process to repack big caps, but I mean for small ones.
FotatoPotato:
No, not that I know of. Just get a new cap
Gyro:
Theoretically, I suppose. Your problem though is that you have no idea what composition of electrolyte was originally used (they vary significantly between manufacturers and types) and you have no way of purchasing it.
That makes it a practical (and economical) non-starter.

The other problem that capacitor failing is not simply electrolyte evaporating. There are more complicated processes behind it. Also how you are you going to safely seal it again and keep vent still doing it's function?

There is none of such BS.

As that leaf falls 100 new Chinese businesses start up selling refurbished name brand capacitors.
Even if you got the electrolyte right, there is other related problems like damage to the dielectric that would make it waste of time as well. I think reforming is about as far as I'm willing to go.
But transplanting electrolyte sounds like a fun evening of experimentation. Who knows it could take off like ink refills.
