The above is true, but our 2004 has been left for a week without
having a dead battery. However, there were two other times the
battery really had been depleted, it turned out someone had been
sitting in the car listening to the radio and then "thought" they
turned it off. Either it was left in the accessory mode or in the
"on" mode (but not started). We now double check that the car is
really off if we have done something unusual like use the accessory
mode in a parking lot. ...Pat

I think it depends on the state of charge of the 12V battery to start
with. I was hospitalized for 5 weeks (and unable to drive for another
week) and had my family turn off the SmartKey system (thank Ghod one
daughter is a computer nerd and able to figure out what I was asking
for), and the family drove the car once in a while, so it didn't lose
the 12V charge. It was a couple of more weeks of driving before I
turned the SmartKey back on; during that time, I took the car in for a
state inspection; it was interesting to watch the mechanic get in the
car, and then try to figure out just why the damn car wouldn't just turn
on when he pressed the button.

I have a 15V solar cell and added contacts that enable
simple connection to the battery lines. Works fine...

That switch turns off the SKS. There is no switch which disconnects the
12V battery.

Right, and the SKS continuously draws battery power so switching it off
saves battery power.
