I have kept my car on a Battery Tender Gel Plus since the day I brought it home. It sits for several days at a time. Despite this I have had to replace the battery once and got the low battery warning once after the battery was replaced.

Car is going back to dealer next week and I am going to insist they replace the battery and under warranty.
Good luck with the battery swap and keep up posted.
