I apologize if this question has been addressed previously. I'm a proud owner of a 2009 Rogue. Shortly, I'll be leaving the country and as a result my Rogue will be parked for upwards of 6 weeks.

My question is, how likely is my car battery to discharge because of prolonged idleness? If so, is it necessary to disconnect the battery or are there some other options? Is a car mechanic required?

Thanks in advance.
