    2017 i3 Rex 12V Battery Voltage

    Thanks for explaining this issue. But is brings me to another question: How can I check the 12V battery with a Voltmeter when the DC/DC kicks in as soon as Open the door, trunk,etc ? I just want to make sure my 12V batteryis healthy and does not need to be replaced.

    2017 i3 Rex 12V Battery Voltage

    When I check the voltage of my 12V battery it shows permanently 14.2-14.4V. (using 12V car outlet) Does it mean the battery is permanently charged via DC/DC from High Voltage Battery ? If not in charge mode the voltage should read around 12.5-13V. Am I correct ?
