I like probably a few drivers use there car less in the winter months. In my case I will be leaving these sunny ( or not so sunny ) shores in a couple of weeks, for six weeks to soak up some sun. As the weather gets colder I would like to come back to a car that starts, so I am thinking of a "battery conditioner" to keep the battery topped up, any one out there with some recommendation as to the best unit to buy and the best way to connect.
