Hi All,

I just got a used 2003 350z Track recently and planning to take a vacation soon. I will be disconnecting the battery during my trip so it will hold it's charge.

One question I had was whether our stock stereo requires a "stereo code" password when I connect the battery again? I know some of the newer cars have this feature and was hoping I don't have to do this. It's an non-Bose stock 03 stereo.

I've checked some of the sticky threads and a search didn't get any results.

Much appreciated... Thanks!

Nope, no code required. I've unplugged mine numerous times with no problem.

Good to know! Thanks for the quick reply!

BTW... I'm leaving my car for 2 weeks (about 16 days). Do you recommend me pulling the battery? Could save me the hassle of reprogramming my homelink etc..

How old is the battery? If it 4 to 5 years old, you may definitely come back to find it dead. I've seen quite a few threads by guys who have left the car idle for a period of two or more weeks and come back to find a dead battery. Apparently the security system and other stuff puts a small load on it when parked.

A newer battery may not be a problem for a couple of weeks. You can always consider buying one fo those battery savers that keeps it on a trickle charge - you just plug it to the wall and connect to the battery.

i would not unplug your car battery for 16 days

nothing to worry about

start it and let it idle 15 minutes the day you go

it will be fine when you return

provided the alt, and battery are functioning and in good working order now

your battery should rest at about 12.8 volts with car not running and it should read 13.8 to 14.4 when running without ac or lights or radio on

make sure terminals have no corrosion

if it is a factory battery and is the original you should get a new one however but i doubt it is the orginal they only last 3 years more or less

Not that I am aware of. You may lose features such as preset stations but that should be the extent.

Sounds good. Thanks for the suggestions.. I'm not sure how old the battery is since I got the car used, but I might just disconnect the battery anyway in case it does go dead.

Cheers!

There are only two reasons I can think of to disconnect your battery:

1. If you have a marginal battery that you do not want to go dead, then disconnect it if the car is in storage or not in use. In fact it might be better to just leave the battery connected and plan to replace it if it dies, or just replace the battery before you store the car.
   
2. If you are storing the car in a very cold climate, disconnecting the battery and removing it completely, and storing it indoors where the temperature is warmer will preserve a viable/decent battery better than leaving it for an extended period in very cold weather.

As davidv mentions, your only liability when removing a battery from a a Z with a factory radio is losing your radio’s station presets and configuration settings (balance, fader, treble, bass, etc.). You do not need to worry about theft-codes since the stock radio does not have this level of protection. The stock radio is pretty much worthless, so it does not need the extra protection of digital theft codes.

No issues with the batt disconect other than your pre sets , if you have power windows make shure when you disconect the batt you have the door you are going to use open proir to disconecting as the window does the seal up and disconecting with the doors closed may cause seal dammage.

Actually the factory battery last pretty long. There were several guys that put 5 years plus on it. Mine lasted just as long with over 1500 watt being drawn for over 3 of those years. It still didnt fail when I took it out I just wanted to upgrade to a bigger agm batt

^^ You are correct. I used the stock battery for 5 years in Minnesota where winter temperatures frequently dip below zero degrees Fahrenheit. In fact I stored the Z without removing the battery for the first two winters I owned the car.

And as in your case, my battery was fine when I replaced it at 5 years. I just didn’t want to push it any farther and wanted a slightly larger battery.
