Bad battery?
dealer most likely will quote you for around $350-400 id guess



Sam's club has it. When I called them before I posted, they said they didn't, but they do. Two choices. Again, this is for 2010-2013 S550 with ONE battery up front, both 3 year free replacement:

I think it has more power than the OEM specs, the new AGM aftermarket. I'll admit I miss the looks of Mercedes branded battery a little, (that's just my **** self) but like the quicker starting.



EDIT, this battery from Sam's has 3 year free replacement, at the $169.

Do the 2011s have this under dash accessory battery? I keep reading different answers and really just want an honest one
