Can one trickle charge the plug-in hybrid model, 740Le?
Seems like the 12V battery cant keep up with all the electric stuff the car is having on. I cant sit even 5 min inside the car with out the "battery warning" going on.
My usage of the car is 90% of very short distances, maybe 5-10km (4-8 miles). This type of usage really eats up the 12V, the main hybrid battery is doing extremely well and I'm getting almost the MPG what BMW claims
I mean 100+ MPG just because I can charge the main hybrid battery often. But the 12V isnt keeping up...
So ... Can one trickle charge (Ctek etc) the 12V at the engine bay?
