I don't think it is an issue with a defective battery from Braille, but more of a electrical draw issue. There are way too many electronic consumers on the E9X cars, especially with comfort access, that particular system might be staying awake at all times, drawing maybe 80-100 milliamps, which can run the Braille batter down in a few hours. a 40-50 milliamps is the typical draw on the late model BMW's that won't cause any problems.

In addtion, if the car is only drive a few miles a day, that is not enough to keep the battery charged. We have seen cars driven on city street coming in for service that only have a charge level of 70%
