How long can the Boxster sit dormant without enough drain to the battery that I would have problems starting the car ?
I recently purchased a second car for the winter, but the Box will still be my primary car as long as there is no snow or salt on the road.
I was thinking of buying this :

But I don't know if it will be necessary if the Box only sits for a week or two.
Thanks in advance for your help !
