Are you talking about after you shut the engine off and is there a timer for the 2 minutes? If you have some unusually hot weather that could be a reason the fan stays on a little longer. I had my fans wired through a toggle switch so I could manually turn them on and off if the automatic thermostat failed. Also sometimes after driving is hot weather, when I parked the car I would open the hood to let the hot air out quicker and turn the fans on for a minute or so. And that would draw the battery down some. But I did it with the toggle switch and watched so I never drew the battery to low.I also kept a battery tender hooked to it when it was setting for a day or so.
