"Just wondering, where can I purchase a battery tender from? "

I believe the one that is available from BMW is made by these folks. I have a the CTEK Multi US 3300 .

They also sell a comfort indicator with eyelets that can be connected to the terminals under the hood permanently and simplifies hook-up.

I think it will still require you to pop the hood because the leads are not long enough to reach the radiator grill.
