beginner question about battery

[fwellers]

Been driving my new prius for about 2 weeks now. ( love it btw, not even done with first tank, getting average 44.8 on short 10 mile commutes ).



Anyway, I'll be going on vacation soon, and the car will be sitting for about 2 weeks. I've noticed that the car makes noises sometimes hours after it's been parked. I think that's something to do with something venting.



Between that, and the blinking light on the dash, and anything else I don't know about, I'm wondering how long can the car sit without the battery going dead to where I won't be able to start it ?

I think I'm talking about the 12 volt battery only, as by my narrow understanding, the big(traction?) battery has nothing to do with starting the car and will automatically charge via ice after the car is started.



I just don't want to come home to a dead car, and have to charge it. Maybe I'm supposed to disconnect the battery or something.



In the back of my mind I think I remember hearing that it can go a couple of months just sitting, but just checking with the experts first.



Thanks,

Floyd

Congratulations and welcome to PC.

Before you go away disable the Smart Key System (SKS) and you should be OK. Make sure you lock it (ensures that doors are closed) and that all interior lights are off. Those seem to be the key reasons we kill our 12V batteries.

2 weeks shouldn't be a problem. As Neicy said, double check all the lights are off and smart key system if you have it.

Thank you both for the reply. Sounds good. Smart key disabled.

Uh how ? haha.

I think I read in the manual there is a place bottom left of the steering wheel, down by the knees somewhere.

I hadn't found it yet. I'll look.

I know this is a different situation than what was asked about but...

The only time my 12 volt battery has gone dead is when I did a thorough cleaning of the interior with the doors open.

Since then I manually turn off the dome lights when working on the car with the doors open and have not had a problem.

I just got mine 3 days ago but finally read the manual last night. Although I haven't had my head under the steering wheel yet the book says there's a button you just push (I believe to the out position) under the steering wheel next to the tire monitor reset button.

That's what I thought. Just gotta go look now. I've sort of half looked a couple of times and didn't see it.

btw, Congrats on your new car!!!!!!

I'm going away for three weeks soon!

What's the longest someone has left their Prius alone?

I've don't have a smart key, so that's not a problem...should I get someone to come and start it half-way through my holiday?

Thanks

:-)

You should be good to go. I would advise against having any person unfamiliar with a Prius start the thing while you're gone. It's much too easy to accidentally leave it in some condition other than completely OFF with everything locked properly, and that would certainly kill the 12V battery.
