ABSTRACT:
Battery charger having means for delivering a trickle charge to maintain a difibrillator battery in a normally charged condition, switch actuated means for delivering a fast charge current to the battery, and means responsive to the battery voltage for supplying operating power to the defibrillator in the event that the battery voltage falls below a predetermined level whereby the charger will power the difibrillator directly in the event that the battery is unable to do so. The battery and defibrillator are protected from damage due to overcharging of the battery by interrupting the charging current in the event that the temperature of the battery exceeds a predetermined level or the voltage applied to the defibrillator reaches a predetermined level.
