2024 Mustang GT on order
Decided to try to start my Mustang yesterday just for grins. I put it into storage at the beginning of November, so it hasn't been driven in almost 2 months. . The place where I keep it doesn't allow battery tenders, so it's just been sitting. I guess the saving grace is that the temperature is kept at a constant 70 degrees. Got into it and it fired right up. Let it run for almost 25 minutes. I really thought the computers would drain the battery. I've always stored my Corvettes with a battery tender, so I never started them once they were put away. Anyway, I'm a happy camper. I did pop the hood just in case it doesn't start the next time and I have to jump it.

Unhook the negative and your car will be fine. Had one unhooked for 6 months and fired right back up but it was back in 2006 so less tech. But I’d unhook my S550 for 3 months and it would fire up.

The car goes into a deep sleep after a few days to preserve the battery - as you have found

Like you, having my convertible asleep for a few month. First day above 50, the car started without a problem.
