Tantal(ums) condensers are usually being very high quality and long-lived, under the assumption that a given circuit is running over long time.
When in long storage, though, tantalums can "forget" their polarity and have a hard time when being exposed to power again.
In that moment, the caps have to go through some sort of reformatting process.
In which they can explode or short, at worst. That's because gases and other chemical things build up too fast inside.
To prevent this, in theory, old tantals would have to be charged slowly after long sleep.
By increasing the supplied voltage slowly over longer time.
That way, they would finally recover, maybe.
Speaking under correction here, though. That's merely what I've been told.
