I don't know that it's fair to call them a battery. A battery has a nonlinear current/voltage relationship as energy is stored in the chemistry. An ultracap is still just a capacitor, albeit a very large one. Charge goes in, voltage goes up as per I=C dv/dt. Relative to energy storage capacity..... yes, they are probably closer to a battery than a "normal" capacitor. -Cory -- ************************************************************************* * Cory Papenfuss, Ph.D., PPSEL-IA * * Electrical Engineering * * Virginia Polytechnic Institute and State University * ************************************************************************* -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
