We have the right battery for your Philips Heartstart AED. Here you can find batteries for the current Philips HS1 and FRx devices and for the older FR2 devices.
Philips designed its defibrillators in such a way that you can easily replace the battery. After removing the old battery and putting in the new one, the device will automatically start a self-test. You will be asked to test the buttons of the AED. After finishing this procedure the AED will indicate the ‘ok status’. For a good self-test it may be needed to replace the electrodes as well.
