    How long can the car be left unplugged in the winter out in the open? Where I live, there are usually at least a few days in the year when temperatures dip between 0 to -10F. If you had say 70% charge left in a 70S, can it survive a 3 day period parked outside without the need for charging? Is there a rule of thumb for % battery loss (time vs temp)?

    One thing we know for certain is that the rules of thumb are very dependent on temperature. Very cold temperatures do cause faster discharge due to battery pack heating. I suggest looking among the Norwegians for a really good set of informed opinions on this issue. Nowhere else, probably, has their depth of experience.

    Check out Björn Nyland's video where he leaves his P85 parked at the Oslo, Norway airport for 30 days while he visits Thailand. The battery was fine when he got back. Loss was something like 1% per day. Look in the Video section here at TMC or search You Tube for Björn Nyland.

    Oh, and the obligatory advice: If you are going to be leaving the car unplugged for a couple of weeks or more, don't keep checking on it with your mobile app! That wakes the car up out of its low power sleep mode and speeds up the energy losses again.
