Battery & Electrodes
Most important for proper functioning of the AED is that the batteries and electrodes are usable. For the battery of the AED applies that, next to the expiration date, a possible deployment or other things may affect the battery voltage. When the battery voltage of the defibrillator gets too low will the AED indicate so. For the electrodes it is most important that the package is still unpacked. When the electrodes are contained in a closed package that hasn't reached the expiration dat yet, will the electrodes and special gel still be good and the AED can be used safely.
