I am leaving for six months. My 2005 Crossfire roadster as well as my 2009 Pontiac Vibe will sit in the garage while I am away. What I have done in the past with my Vibe was to disconnect the battery while I was away and reconnected it when I came back and never had any problem with it. Can I do the same with the crossfire? Will it mess up the electric system?

 

You should just have to reset all of the presets, radio clock etc. Be sure you unhook the negative connection first, when removing, and hook up the negative connection last when re installing.

 

Thank you, Zeracer!

 

Personally I would never let the Crossfire sit for a long period of time with the battery either disconnected or unattended without a battery tender. Too many SKREEM issues after letting a car sit without a charged battery.

Just my opinion, James

 

I think it is caused more by the spark of hooking the battery back up than leaving it disconnected. Especially if you hook the positive up last. Jump starting can also fry the electronics. OMO

 

Make it spark just once, hit the post once and slide the terminal down the taper on the battery. Keep the terminals and battery anodes clean at all times.

 

If you are really paranoid about the sparking, get a 1K resister and bridge it between frame ground and the negative terminal before you connect the neg cable.
The 1k wont pass enough current for a spark, but will cause no difference of potential when the big cable is connected.

 

I’m interested to know why you state this James, I have been removing the batteries from my Crossfires when storing them for the Winter and charging them monthly on the work bench. I’ve done this for 10+ years without any ill effects. Am I tempting fate? Thanks

 

Steve, I have read too many times that someone brings their car out of storage or finds that they have a dead battery on a car that hasn't been driven for a while, and then they have the SKREEM scenario when they go to get it running. These car are aging and more and more SKREEM issues will be coming along.

I prefer to keep mine charged to minimize chances what ever the cause. I don't think I read exactly what the problem is with the SKREEM when they won't work. Programming, physical defect, burnt component on the board, etc?

James

 

You would have to prove to me that hooking up the positive last causes more spark. Hooking up the negative last is a safety issue.

I leave my battery connected and leave a battery tender connected all winter while parked inside
I check the battery voltage monthly and the owner of the motor condo where it is parked is there frequently
I'm not sure I'd be comfortable being away for 6 months with a battery tender connected though

 

Thanks James, I appreciate your feedback!

 

AND, hooking up the NEG last (as well as disconnecting it first) will keep the siren happy.
