Then use the device normally after this
It's not how long i had them in storage, it's how long the store (that i bought them from) had them in storage. But i reformed them (according to the instructions i found online) and they seem to work fine.

I'll plug a small load into it tomorrow and leave it plugged in and see if it holds up.
