[Teutonic]

As I promissed, I am back with the results.

I was away for three and half weeks, the X1 was locked in the garage (so the alarm set). I wanted to do this test, so before I left, the trickle charger was connected until the battery was fully charged.

Came back from Europe, the car start right up without any problems or any other errors on the display. A pleasant surprise.

However, I have connected again the original BMW trickle charger to see how much the battery discharged during this sitting period and how much time it needs to be fully charged again.

The battery was fully charged after exactly 12 hours.

In conclusion,the vehicle was good to go and able to run, but something it is using power even in stand by. Now, it is summer and the temperature in the garage was arround 18-20 degrees, sometimes warmer I presume. I don't know if the results will be the same under different circumstances, i.e. winter and some good minus degrees....
