Battery Drain Question
Have a stock 07 coupe. We will be on vacation for two weeks without the car. Will the car start on our return - or do we need to connect a charger to ensure it starts?
Thanks

A well charged battery even on a C6 should make it two weeks. I've gone two weeks with my '05 without problems. With that said, If you have a charger, I'd just go ahead and hook it up. Why risk it and have to deal with the aggrivation upon your return?

Mine sat 3 weeks in 20 degree weather and started right up.
Stop worrying and enjoy your vacation.

It's not the battery it's the car. If your car doesn't have a drain problem, it will be fine. If it has the DBS drain problem it will be dead in a few days. A dead battery will freeze, a charged one will not.
Ask the dealer if your VIN falls in the dead battery bulletin VIN range where they are reprogramming. If it doesn't I wouldn't sweat it. If it does, get it reprogrammed at the dealer or leave it on a Battery Tender until you get a chance to get that done.
That is one of the huge mistruths about these cars that they have junk batteries. The batteries are fine, it is that some cars have way too much parasitic drain and kill the battery. So many people put in real expensive batteries and constantly leave them on a charger. That is kind of a band aid solution and not really fixing the problem of excessive parasitic drain which is what the bulletin for reprogramming fixes.

I've had to battle this problem and have had the car into the dealer several times. Last visit I asked for the newest flash and was told I didn't need it. They noted on my workorder that the car has a 16 milli-amp drain and that it is within spec. I'm guessing that that will drain an Amp every 60 hours. How long should it last before not starting? The car has gone 7-10 days at times and still started and other times only 3-4 days (or less.)

I really don't think our cars should need to be on a tender when driven almost daily or left to sit for a week or two. None of my other cars need this crutch.
