Dude it takes a little while, most people work its only been a day..
anyway batcaps are well worth it, there about the same price as a good capacitor, but they work alot better. which model are you looking to get? depending on what kinda power your gonna push theres different ones for each application. i have experience with the 300,400,800 and, batcaps are pretty much a battery, that can discharge as quick as a capacitor,except with more power
