The electrode pads and batteries of an automated external defibrillator always need to be replaced before they reach their expiry date.  We sell electrodes and batteries for ZOLL, Philips Heartstart and LifePak AEDs so that you can keep your defibrillator in tip-top, life-saving condition.  We also stock paediatric (child-sized) electrodes, where available, for all the AEDs we sell.
