Dead battery

Came home from grocery shopping, unloaded car came back out to go to hardware store but car would not start. All indications of a dead battery. Put it on charger for a few hours but it would not go above 13.2 volts. Charger returns fault code of sulfated battery. My question is, does stopping the car by pressing the Engine Start button and then leaving the fob the car while it is not running drain the battery. The reason I ask is the only time this scenario could of happened is when we went to dinner a week ago where we valet parked it.

Yes

http://www.bawarec.ru/manuals/3er/e9...3er-e90-12.pdf

the people that have battery problems have been told to lock the car and
keep the fob far away from the car as a starter to reduce battery depletion

The battery's in these cars are lasting 6 years average for drivers that have the
ideal driving profile. A lot less for those who use the car infrequently or only go
for short drives.
The car draws .5 amps when awake and not running , it can stay awake as long as 30 minutes if
you don't lock it.

If you fit in the low use short drive profile you need to get a battery tender such
as a ctek3300 or better.

I have a smart charger and hook up the car at least once a month to charge it to full capacity. Its my wifes DD and she put 8000 miles a year on it, mostly commuting 15 miles each way. It turns out it was a shorted cell, covered under warranty by BMW Honolulu. Thanks for your input and advice.
