5.8 Installing and Using the Battery
1. The battery life depends on how often the device is used, charge/discharge cycle, storage
condition and operating temperature.
2. After being fully discharged, it takes up to 3 hours in room temperature to fully charge. The
battery run time depends on how much battery is consumed. Given that the battery is fully
charged, you can measure EEG for 6~7 hours. The battery is designed to last 250
charge/discharge cycles. If a slowdown in battery performance is observed, replace the battery
by contacting the manufacturer or service center.
3. The battery is charged when you connect the USB-C charging cable with the device. When the
device is in use, the battery will not charge. The LED indicator on the power button will be
green when the device is charged more than 95% and magenta when charged less than 95%.
