On Wednesday June 1st, I hooked my '11 E70 up to a BMW original battery maintenance charger. It's crazy that I even have to think about hooking my $70k BMW to a battery charger, but I knew we would be in Hawaii for 5 days. Just 5 days!

But, I made sure I fully charged the X5 before we left, and kept the car on the battery charger until about an hour before we left for the airport.

I locked the X5 and left it in the garage. I even knew the car had to be locked, to prevent any further battery drainage..again crazy for a new BMW!

It's a damn good thing we took our '11 Range Rover to the Airport. Our flight arrived late last night (June 6), so it would have been horrible being stranded in a parking garage with a very tired and cranky 4 year old!

I was greeted upon returning to a 2011 X5 with 4,500 and a dead battery. I cannot believe after fully charging the battery, and being locked and parked for FIVE days that the battery cannot handle this. What do business travellers do? I am just so annoyed and actually pissed.
