First the car was outside all weekend as my fiancee doesnt have a garage. Second I didnt drive the MINI E all weekend so the battery wasnt warmed up. And Third we swaped the cars and I left it unplugged the night before, as her driveway is only one car wide and I cant reach the power outlet if I'm the first car in the driveway. <br>Im driving at 5am so there is no sun to warm the car. Next time Im going to try running the heater the night before to raise the battery temp, and keep it plugged in all night and swap only the cars in the morning just before I leave.<br>Does anyone know if just having the car plugged in with a full charge if the batteries will stay warm, or if thats only if they are charging? Maybe I should deplet the batteries to 60 or 70% the night before so it has to charge them all night long.Roberthttp://www.blogger.com/profile/05065916334723386509noreply@blogger.comtag:blogger.com,1999:blog-5067499087260210670.post-9793048285904647932009-10-26T13:00:36.003-07:002009-10-26T13:00:36.003-07:00Robert,I don't think keeping it plugged in wil...Robert,<br>I don't think keeping it plugged in will do anything if the car isn't charging. I like your idea of running down the batteries (as much as possible)and then allowing the car to charge up overnight. I get up an hour or two before I leave for work and I am planning on preheating the car for 1/2 hour or so on really cold days then plugging back in to get 100% charge before I leave in the morning. That way I'll have a warm interior and battery, plus 100% charge when I leave.Tom Mhttp://www.blogger.com/profile/00302557992187975325noreply@blogger.com
