External Battery
A connected external battery should replace or support the mounted one to keep accurate date and time. It is
recommended to use a model with 3 Volts (CR1225). The time and date will be lost if the power falls to 2.5
Volts.
For real-time calculation (worst case), 4 µA (25°C) are needed when the board is not running. That value can
rise depending on the connected cables and higher temperatures.
