External Battery
A connected external battery should replace or support the mounted one to keep date and time.
It is recommended to use a 3-volt model (CR1225). The time and date will be lost if the power
supply falls to 2.5 volts.
For battery-life calculation (worst case), 3 µA (25°C) are required when the board is not running.
That value can rise depending on the connected cables and higher temperatures.
