Google away - lots of information is out there on this including from BMW
Thank you. This does make perfect sense, and as such the car is locked, always locked actually.

As for the tender vs trickle... i've googled and searched in the past... but I value the opinions here quite a bit too. Remarkably I havent found a product description I really trust. yet.
