Anyone know what is causing the discharge?
I had charged mine up a month ago and then yesterday it was dead, dead, dead. When I hooked up the charger the first thing I heard was a loud clicking somewhere in the neighborhood of the radiator. I ended up pulling the cables and then pulled the battery. On my charger it would only take 2 amps for a while and after 5 hrs it was fully charged. I then did a load test and it was fine.

Someone told me that the C5's should be left in reverse when parked over time and my owner's manual also states to do this (although it doesn't say why). I was told this turns off all the electrical except the alarm and prevents drain on the battery but other Vette buddies have told me this isn't true. I've heard stories of people going through batteries until they started to do this and then their problems ended. I don't know if there's any merit to it but I still leave mine parked in reverse if it's going to sit for more than a few hrs. I figure it can't hurt.
Can anyone confirm this for sure?

Leaving it in reverse can't hurt anything, but it isn't required...unless you're parked on an incline, of coarse.

I too use the Battery Tender Plus on my car. Used it on my previous C5 too and it worked great to keep the battery fully charged up between driving times.
