Claim:
1. A defibrillator system comprising: a battery having a battery capacity; a capacitor for storing a charge; a charge circuit to charge the capacitor from the battery; a discharge circuit to discharge the capacitor and deliver a biphasic waveform to a patient; user interface controls connected to the charge circuit and the discharge circuit and configured to receive operator instructions and to provide system information to the operator; and a microprocessor-based self-test controller for testing the system; wherein the microprocessor-based self-test controller periodically initiates a test of the defibrillator system to determine (i) whether the battery capacity is below a predetermined threshold value, and (ii) whether the capacitor charge circuit is functioning within predetermined parameters; and further wherein the microprocessor-based self-test controller only runs the battery capacity test and the capacitor charge circuit test if the defibrillator system has not previously failed a self-test.
