RTC Backup Battery

The expansion board supports a CR1225 coin cell backup battery. This backup battery is connected directly to the module and powers the module’s time management unit’s data, configuration, status registers, and timekeeping logic in the case of power loss.
Note: 
 If the expansion board is removed from power (for instance, if no power is provided from the DC power jack or the USB Type-C connector) for an extended period of time, the back-up battery may drain to below the minimum operating voltage, with the result that the data stored in the Intel® Joule™ module PMIC time management unit may become invalid.
