Replaced the original battery in my '06 yesterday. Lasted from April/06. The car sits in a heated garage most of the time, but may go 4-5 weeks between starts. What are the thoughts on a battery tender ??..(I HATE leaving electrical items unattended.)..or just disconnectong the cables..Also saw the thread about pulling the ONSTAR fuse ??..Suggestions welcome...thanks..j

 

I would suggest a battery tender. We use them all winter when storing cars.

 

I've got one mounted under the hood on my Vette, that I've had for years. Also one mounted on my electric start generator. They're great!

ive had some extra vehicles, or cars you could not drive on wet pavement/snow. i never let one go a week w/o a run in'
i kept my 460 stang in a 50 ft pole barn. did a complete warmup through winter and did 40 foot burnouts to let it know it was always loved. also had a box fan running to move air around it. helps stop rust.
i had a new van that got bad seals because they let it sit too long on the lot w/o moving it,axel seals.
a batt tender is great,, a "car" tender is better!!

 

X3 on the Battery Tender. I use to go thru a battery every 2 years on our classic. After the battery tender, same battery going on 5 years now!
