External Battery
A connected battery should replace or support the mounted one to keep date and time active during the board is
mechanical off.
It is recommended to use a model with 3 Volt, but it will also work with power suppliers up till 3.6 Volt.
The BIOS setting will get lost if the power supplier falls down to 2.4 Volt.
For live time calculation there are 2.3 µA (25°C) needed when the board is not running.
That value can rise up with higher temperatures.
