I am getting a turtle today. Turned the car off and on about 5 times, and get a turtle and "output power is limited" message after about 10 seconds. I was originally getting 12v battery alarms, so I charged the 12v with a Battery Minder. But now, "it's turtles all the way down." Ambient temp has warmed up to -14F outside (-13F on my dashboard). Battery has 1 temp bar. LeafSpy says battery temp is between -1F and -2F (sensors 1, 2 'and 4 reporting).
I charged the car to 100% yesterday (finished at 7pm) in anticipation of the battery heater sucking power all night long. However, at noon today, the car still claimed 100% SOC. If the battery is insulated enough that it never got colder than -1F, then that would make sense (that there was no power loss overnight). But if the battery is only -1F, then I don't understand the turtle.
Does the battery heater only work while the car is charging? Or does it kick in with an unplugged car?
