I recently had the 12-volt battery on my '18 Model S go dead. As I try to find out how this battery is charged, one Tesla service rep told me it's only charged by the heavy-duty battery system while another Tesla service rep told me it is charged by the wall charger. Does anyone know the truth as apparently the Tesla service reps do not know. Thank you.
Related to this issue are uncertainties coming from the Tesla folks about the "best" way of charging the batteries - how often and how much. One rep told me to plug the car in every night. The other told me to charge it only when needed.
Thoughts and explanation will be appreciated.
