To answer the question regarding a battery on a daily driver, yes 3 or more weekly runs in a X5 of trips of more than 60 mins, will keep the battery within a full state of charge. Making the assumption that you are driving over 40 miles per hr average. Idling, short trip lengths, stop and go traffic with all the electrical loads on (lights, A/C, Blower motor, wipers, stereo pumping, etc) will NOT charge a battery but will in fact accelerate the drain on the battery. Nor will it allow the engine to burn off all the water (moisture) in the oil pan so the oil separator will freeze up as soon as winter comes back.
Wait, you live in the upside down world of the globe. You are in winter now, sorry.
