David, >From the slides you posted it looks like you have some kind of automated set up. Can you explain what you have there? The limited reforming I have done has been done manually. I also notice that you reform over quite a few hours, but those are big caps. Not sure I have seen any suggestions over how long to reform for, and whether it is a function of the capacitor's nominal capacitance. Thanks Rob
