Battery problem

[kevinc23]

After reading these messages, if the Battery charges twice as fast in ready/park mode, I'm going to leave it in ready/park when I give it the weekly wash. The engine should only start a few times with the traction Battery running most of the time. Not sure if the doors will lock for security though.

I let mine charge in the garage in ready mode (garage door open) car doors closed, key on seat. I don't believe the car will lock the doors in this situation

A 12V Battery will have around 12.6V when fully charged. It needs to drop down to around 10.5 volts to be considered fully discharged. If it drops down below that, the Battery will become damaged due to excessive sulfation. So 11.4V is not a problem.

If you look at the chart below you'll see that 11.4V is quite a big problem:
