a second battery unit operably coupled to the defibrillator;
a battery charge monitor configured to determine a remaining charge of the first battery unit and the second battery unit; and
a controller having a processor, the controller configured to:
cause the defibrillator to use only one of the first battery unit and the second battery unit during the second operating mode,
cause the defibrillator to use both the first battery unit and the second battery unit during the first operating mode, and
