After 3 to 4 days of leaving the car parked, there is not sufficient power to start the car. I estimate the voltage at below 9 volts as the interior lights barely come on. If the car is used daily there is no issue with starting. I switched the kit connection to a "ignition on only" power supply and the kit can't deplete the battery. Of course you don't get any parked car operation!
