First time I hooked it up, I hadn't driven the car in about 3 weeks and the power pack died overnight. Since then, I've been charging it once a week, and the power pack lasts for about 24 hours when the battery tender is in "maintenance mode".
Since charging the battery once a week, the battery tender usually goes into maintenance mode (full charge) in about 5-6 hours max. My clock hasn't lost any time whatsoever since I stored it for the winter so it's been working great for me!
