Jackpot!!! I finally found them! Here is the link on the Elna homepage for distributors for the Dynacap Double Layer Capacitors and they are cheaper than I expected them to be. http://www.elna-america.com/Distributor.htm#top I searched for nearly 2 days for these things and finally found them. Check out the following site if you are new to Super Capacitors as they describe all the many advantages of using them in place of rechargeable batteries. http://www.chipcenter.com/eexpert/akruger/akruger008.html Elna's Dynacap capacitors have one of the highest charge/discharge ratings of all the other super capacitors that I've checked into at over, an amazing, 1 million cycles! At that rate they should last the rest of my life, and might possibly even outlast the LED that I use with them. I never dreamed when I first started this quest that I would find any power source anywhere that might actually have the potential to outlast a long life LED.
