tried charging it up and it doesn't hold a charge for very long.. voltage slowly drops off
I got an order of 6 of them.
I can't use the 6th one because when I try to charge it with the right polarity it doesnt hold a charge and the voltage drops quickly compared to the other ones
is there any way I can revive the super capacitor without opening it up and possibly being exposed to toxic corrosive chemicals?
do I just have to use the capacitor backwards?
because it holds a charge if I charge it backwards!

They put the layers inverted.
Open it, unroll the foil, and roll it again backwards.
Don´t worry about the salt inside, as long as you don´t lick it.
Wash your hands afterwards.

Will it loose a huge amount of capacity if i do that?
And how will I do that without butchering it?
Wouldn't it be simpler to cut the connections internally with some snips. flux them carefully. flip them around and re-solder then re-insert it back into the can?
it would be neater and more solid connection..
if I charge it really slowly in reverse for a really long time at a constant voltage will the plates slowly reverse the oxide layer and become the forwards direction?
Aren't they mostly netrual to begin with so could I do that if I wanted to wait long enough even if it were to take hours or days to finish thats fine with me.
I have a constant voltage power supply constant current
I could charge with 20mA to 800mA and keep the voltage at 2.75?
or will it never reverse the oxide layer no matter how long i leave it for?
I dont want to take it apart and if the foil layers is super tight and compact it would be hard to roll back together especially hard to do neatly.
I dont have the tools. and I dont have any gloves.
and I dont want to butcher it and have it be unsealed and dry out the electrolyte.
