Will the battery of Philips defibrillator fail to discharge at low voltage?

Yes When the battery of Philips defibrillator is at low voltage, it can work with alternating current: starting, selecting energy, charging 200 coke and discharging. When you finish these programs, the following will happen: 1. At the top left of the screen, there is a prompt "No electric shock", 2. The patient will move slightly, 3. Impact: 0 is displayed in the lower right corner of the screen. I suggest you replace the battery! Emergency nurse
