Battery Drain on 1005 C6

Battery Drain on 2005 C6

My C6 was ordered end Aug. 2004 and delivered 2 Nov. 2004. In Feb. 2005 I needed a jump start from AAA and the dealer found a dead cell in the battery which he claimed was creating a draw. A new battery was installed. Last Friday, 17 June, the battery needed a jump again after the car had been sitting only 3 days. The dealer found nothing wrong and even called Chevy Tech Center which claimed they had experienced no problems such as mine. My Vette has NAV system, Z-51, 6-speed, etc. I am very conscious of putting the transmission in reverse as the owners manual demands. I ran this by a friend who ordered a C6 at the same time I did. Our cars came in on the same day and the same delivery truck. He has been experiencing the same problem with battery drain and thought it was his fault, but he is also very conscious of leaving the car in reverse per the owners manual. I find this very strange since there are now two cars with the same problem. Have any of you other C6 owners experienced problems with battery drain? I feel that there is an intermittent problem here which Chevy has not yet experienced enough to warrant an investigation, come up with a fix and perhaps even a recall.

there is obviously a drain on the battery someplace - you need to find it - do you have a radar detector or anything else you have have added? cell phone left plugged in - just throwing ideas out that could be causing a drain

No, we went through all that at the dealership. They even asked if I left a key fob in or near the car. Nothing was on, no cell phone, no accessories in the cig lighter, etc. The car has sat for 3 weeks at a time and started, but this time it drained after only a few days. It appears to be intermittent. Thanks for the suggestions, however.

Surely they know how to check for a current drain from the car's circuitry, and/or a proper check of the charging circuitry.

I would not be at all surprised to see a bad production run of (new) batteries, either.

John ,the dealer claimed that the new battery is good??

 

[John_Scherer]

Yes, the dealer claimed the new battery was good. This time the mechanic claimed that he just fully charged the battery. Time will tell if the problem repeats. I even put over 700 miles on it this time travelling back and forth to Las Vegas. The battery should be fully charged. The alternator checks out good also.
