Dead battery
I left my '04 Z06 in the garage for two weeks and the battery went dead. The battery is good so there must be a bigger than normal drain.
I charged it up and attached a Battery Tender.
But only two weeks before the battery went dead? What if I need to leave it at the airport? Two weeks does not sound right.

With all the electronics on these cars, it's normal to have a battery drain. Most guys leave their car on a battery tender if they aren't driving it for more than a week. You may want to invest in one

I do have a Battery Tender to cover me for those times although once I didn't start it for the better part of 6 weeks and the battery was so completely discharged that the battery tender would not even charge it (even after 3 days) and I had to bust out my heavy duty DieHard Charger to get it charged back up again. Sheesh!!

I have a brand new optima red top I put in last year, even with that it was drained to nothing after I let it sit for 2-3 weeks this winter. Battery tender wouldnt recharge it either. Had to hook up some heavy duty jumper cables to it from my truck and let the truck run for 30 min or more before it would begin showing life again. After that I just hook it up to the tender after Im done each weekend.

I appreciate the replies. As long as it's normal, I'm not concerned. I'll just keep it on the Battery Tender when it's going to sit for a while.
This is my second '04 Z06. The last one was a daily driver so I never had battery issues.
Thanks

I can let my 03 sit for 3 weeks and it struggles to start, 2 weeks is fine, I use autozone gold....key is reserve power. for what it is worth optima is crap for cars that sit...i work at a battery company and that is my experience....however to each their own. I never use a tender/maintainer on my car. good luck.

I bought my 03z in August 2012, it had a Delco. It sat with no tender from mid Septemeber to mid December 12 weeks +/- stated right up. Two weeks later it went dead while I was installing the new radio and had the acc on for hours. Had it tested and it had a bad cell, so I replaced it with an off-brand.
