This is so true. My husband's 2005 Dodge Magnum has sat as long as 6 months and fired right up. Ditto our '67 Mustang. My 2011 Chrysler 200, however, sat for three and had to be towed to the dealer and a new battery installed. We should have had a charger on it or disconnected the battery. Fortunately it was still under warranty, so we paid for nothing, not even the tow. But lesson learned.
Also consider the age of your battery. We did have a problem with the Magnum once after 2 months of sitting. But it was in 2011, and it was the original battery. Had to replace the battery, and since then no problem with it sitting for length of time.
