Your battery stays on for a bit after you shut your BMW off. It will remain on to operate functions such as your radio, lights, clock, and even your security alarm for the car after you’ve left. Your BMW may experience and electrical glitch, where some systems turn off but others such as your lights remain on which can drain your battery. Be sure to check all electric items are off when you leave your BMW.
As previously stated, lights can be one of the biggest energy sucks for your battery. There is almost no quicker way to drain your battery than by accidentally leaving the lights on. If this happens overnight, your battery will be dead by the morning.
