Charging Dead 12 volt Battery

[BBurdett]

Without getting into how; I had a dead 12v battery. That meant the elecronics were dead and the car would not accept a charge through the charge ports. Kia Toronto put a charge into the 12 v battery and all was resurrected. Question if this were to happen again: Can a charge be put into the 12 v battery using a cigarette lighter outlet as can be done in an ICE vehicle?

Should work unless the car needs to be "on" in order for the cigarette lighter socket to be energized.

When it happened to me, 2 days after I got my car, I disconnected the 12v battery "Positive" terminal, and connected a 12v battery charger to bring the battery up to a reasonable level. From what I recall, when I reconnected, the car only lost the temperature units setting.

Same thing here. Car died. Jump started it. Worked fine. However, the temperature units changed from English measurements to French measurements.
