It vehicle storage time in the non-warm part of the country. My doctor use to complain that almost every time he got into his Viper the battery was dead. That was after 1 or 2 weeks of not driving it. I have heard that from other owners and when I got my 2005 convertible I realized the problem. When you set the alarm a red light inside at the top of the windshield would flash continuously as a warning that the alarm was on. Well, that light gets it's power from the card battery. SURPRISE the battery drains. During the pandemic shutdown many vehicles in my condo's garage suffered the same fate. Unless you store your Viper off-site during the good driving weather Don't Set the Alarm. Long storage use a battery tender so you can set the alarm. I'm sure most of you already know this but I just needed to write it down out of frustration in my condo's garage.
