ZOLL
Here you can find batteries for Zoll AEDs. Zoll has two types of AEDs: The Zoll AED Plus and the Zoll AED Pro for semi-professional market. What is unique about the Zoll AED Plus is that it makes use of 10 Lithium batteries.
Both AEDs start a self-test after replacing the batteries. If the defibrillator is ready to use, this will be indicated with a tick on the AED. In case it is not ready, you will hear an alarm and see a cross at the display.
