Due to a shoulder injury I've been unable to drive my Roadster for two months and possibly not for several more weeks yet :-( I don't have a garage, and so it's left outside. Occasionally a friend takes it for a short drive. I was leaving it unplugged and kept the charge level around 50%. However after several weeks outside it's been regularly refusing to commence charging except after a drive - due to the well known condensation error issue. So, now I keep it plugged in constantly on Standard Mode but I'm concerned that it's sitting with a full Standard charge for such extended periods. Should I put it in Storage Mode instead? Is Storage Mode ok when the car is kept outside over a (UK) winter? Thanks!
