Wtf is this?

[redrooster]

I bought 10, 3300uf,6.3v kzj caps from fleabay about a year ago and two of them have no readings with a capacitor meter and they are puffed out like they have been installed the wrong way or something,have you seen this before just from storing them? They were stored in a cool spot the whole time The rest of them seem OK but can they be trusted?.

I've seen that before with Fuhjyyu a few times. Given how low quality KZG/KZJ are, it wouldn't surprise me at all if they can do it too.

yes we have seen previously on this forum the chemical process occurring even in non powered storage. i would discard them all.

I would discard them all anyway, even if they didn't fail in storage. They are KZJ after all.
