I have mine set to 12.4V and my car can sit for 9 hours without triggering the voltage cutoff. That's on a 2-3 year old battery in a car that gets driven 1-2 hours daily. I wouldn't want to overwrite that much footage while it's sitting in my garage. Plug I wouldn't want to put undue strain on my battery and memory card for no reason. It's easy enough for me to just manually turn off the camera when I park in my garage (haven't forgot yet, but the wife has).
