yep they are close to useless they barely store any current I agree but I am looking to see if it does make any difference in keeping the voltage maybe 1/2 volt steadier. If it does in the long run it will be easier on the rest of my electronics they don't like voltage fluctuation. If this little 3 farad turd that been in my garage for ten years can do something like that i will be happy. Will it, I don't know.According to the math that was in that 20 page report it should help but only when there is enough current there already. If i was to buy something new to add it would be a battcap because of the low esr.
