I'm about to leave my 2019 Fortwo in storage, unattended for about 4 months. From what I've read, I shouldn't be worried about flat spots in the tires due to the light weight of the vehicle. I've read conflicting reports on what to do re the two batteries, however. Some folks suggest fully charging prior to long term storage, some suggest only charging to 40 or 50%. With respect to the 12 volt battery, some recommend using a smart charger to keep it maintained, others suggest simply disconnecting the GND until I return. Any suggestions or recommendations? Thanks.
