Powerboost 12v battery charging tip

[marekjk]

Found an interesting twist to this issue of setting the blower to 5 or higher to get the 12 volt battery up to 100% SOC.

If you are sitting in the driver's seat and set the blower to 5 or higher, the voltage will rise to a temperature compensated range of 13.7 volts to 14.2 volts and over time the 12 volt battery will reach 100% SOC.

Now if you open the door and step out of the truck with the engine running and shut the door simultaneously with the "beep beep" of the horn the 12 volt battery voltage will fall to 12.7 volts. Get into the seat and shut the door and the volts will jump back to the 14 volt range.

You can't make this stuff up it is so stupid. What are they thinking?

Wow, good catch. I am with you, what are they thinking?
