    Greetings everyone:
    I am planning on parking my 2014 Volt with 24,000 miles during the Winter.. It will be parked in a heated garage during the winter. What if any damage can occur? Thanks in advance.
    Respectfully

    No real damage should occur, however I would take it for a drive every now and then. The 12 volt AGM battery in the trunk will die and you should keep the engine lubricated at least once every two months.

    Short answer: According to the owner's manual, if you will be storing the car for more than a month: Run the battery pack down to approximately 50% charge, then park and disconnect the starter battery. (Do not store long-term with the main battery pack at or near 100% state of charge!)

    Longer answer: See discussion at the GM-Volt forum here.

    I read something along the same lines for the Clarity plug hybrid about a partiall charge during storage over a month.
    Does anyone know the reason why?

    It's a basic property of li-ion batteries. Storing them at either full charge or near zero charge puts strain on them which shortens their life. Storing them long-term at between 50-60% of their full state of charge is best. Caveat: What the car's instrument panel displays as 50% or 60% may not be exactly that, because what the car displays is usable capacity, not full capacity.
