So I have a dead battery(my car is an '07 328i with 33k miles). It's Sunday night, so most shops are closed. I did call BMW Roadside Assist and was was going to have her towed to the dealer but I changed my mind and canceled the call. My car is parked in my office parking lot, in "my spot" which is away from possible door dings, and only about 500ft from my home. I thought maybe I should do some research first before having the dealer put in another OE battery and charging me some nutty amount.

Any advice ?

I am also considering lightweight batteries such a Braille if they're reasonably priced and I can get one soon. And what sort of cost am I looking at ? and any installation tips ?

Thanks in advance for any helpful info,
R.S.
