Today I had the emergency flashers on for two hours on my 2016 Leaf. That apparently drained the 12V battery, since I couldn't open the car with the button. I got in with the physical key and used jumper cables to get things up and running.
Here are my questions:
1. Does this indicate that I should get a new 12V battery?
2. If this happens again, can I assume that I can just disconnect the jumper cables and drive away, confident that the 12V will be charged from the drive battery (or should I wait awhile)?
3. Please tell me under what conditions the drive battery will charge the 12V (while charging from the wall? While waiting to charge (timed)? In ready-to-drive mode? Accesories on mode?).
Thanks!
