It appears the battery used by bmw is made by Banner Batteries.

The battery used in the 135i is rated at 90 amp hours. I'm having trouble finding the weight of the battery on the banner website, but if you look at a similarly rated Odyssey AGM battery it weighs 77lb!

So.. we're going to lug around a battery that weighs 50lb more than a pc925 so the car can shut itself off at stoplights..
It just so happens that a spare tire weighs approximately 50lb. I'm pretty sure I would rather have a spare tire and better performing non-runflat tires.. than have a monster battery to support stoplight engine shutdowns.
Hmm.. if there is a sensor at the battery.. what happens if you remove the oem monster battery and install a 25lb Odyssey AGM? The voltage sensor will realize the smaller battery is running low and will defeat the other stuff, right? hehe..
