I have been getting the same “charge battery” message the last week or two. It’s a 2012 Li with a little over 4k on it. I got it in April, but come on, the car should still start.
I'm sure the dealer is going to tell me to put a charger on it. So what is the recommended charger of choice? I don't really need one that say's BMW on it.
100% BMW. Don't settle for cheap imitations.
