Thanks Ed and JFP...sounds like store and leave is the desired option. The Porsche dealer sold me a trickle charger that plugs into the cigarette lighter and told me to leave the front hatch closed, but ajar, in case the charger's fuse goes for some reason. Apparently you can't get into the battery compartment if the car's battery if dead....interesting! Appreciate the tips and will try. Can't wait for the spring to come as I've only had my car since start of October and loving it!!!!
