Believe it or not I replaced an Optima with my Kinetik!!!! I haven't had any problems at all!! I don't even need a capacitor connected to the amp. I have a 1 farad but I tell you even with out it my lights do not dim or flicker and I can finally have my stereo on for a while with the truck off without worrying about it not cranking over. Definently a great battery. I wouldn't be surprised if you could run a small onboard welder with it!!!
