I just got back from a four day car camping trip. From about two days, my car was parked and basically never opened except for unloading. Because of racoons and such, I kept my dry food stored in a bin in the back and I'd do a lot of opening and closing of the car at dinner and breakfast time.

When I started the car to leave, the clock was blinking and I had a warning message about low battery.

Is this normal behavior? There was certainly some discharge of the battery over those three days (although not extreme, by any means. Should I be concerned?
