CMOS battery power consumption was measured with an ETX®-LX module on a standard Kontron ETX®
evaluation board. The system was turned off and the battery was removed from the evaluation board.
The 2.5 V or 3.0 V of power was supplied from a DC power supply. Do not use these values to calculate the
CMOS battery lifetime.
