During continuous monitoring of SpO₂ and temperature, with an Interval BP set for every 5 minutes, a fully charged battery should last at least 4 hours before requiring recharging. If only taking manual BP measurements, a fully charged battery should last for at least 150 BP measurements before requiring recharging. Fully charging the battery should take under 6 hours. Battery life is dependent on the screen display ON time. To maximize life, SunTech suggests changing the Power Management setting to 5 minutes.
