A defibrillator in which electrodes with a limited shelf life are stored largely out of view from the exterior of the unit, but the expiration date or other marking indicative of expiration or failure is positioned so as to be visible from the exterior of the defibrillation unit. A fracturable member is attached to the defibrillation unit so that opening the defibrillation unit requires fracturing the member, thereby providing an indication of whether the unit has been opened. Electrodes are releasably attached to the inside of the cover of a defibrillator, so that when the cover is removed the electrodes remain with the cover.
