The lithium/iodine battery is the most widely used power source for implantable cardiac pacemakers. While the average power demands of pacemakers are very low, the instantaneous power requirements can challenge the capabilities of this high impedance battery. Thus, there is a need to predict the transient-response behavior of new battery designs.
