Ok, for the last couple of years this has not been an issue for me. During winter storage I kept my 1996 Vette on a battery maintainer (minder). In season I use it at least once a week and it fires up fine. I have never had a problem. A few weeks ago I went away on business for 2 weeks and when I returned and tried to start her up the battery was dead...ok the radio stations were still programmed, but the time was way off and not even a clicking sound from the starter. So, I charged the battery right up and since then all is well. Even left it a few days just to see and it starts fine. Dash indicates charging 14.9 after startup and then slowly works its way down to 14.1. Battery is the stock Delco, one year old. Alarm system is an aftermarket "Crime Stopper", but when garaged it is never set to on. I know the 96 computer's diagnostic codes were up to 140 from 95's 60 codes, so maybe the computer is draining more than I think. The car is stock outside of the alarm system.
I know these computers do drain the battery slowly, but I'm wondering if there is something else that is also very slowly using power. Therefore, it seems the car can sit a week and be fine, but not two weeks. Any 1996 owners who know their battery life while sitting? How about other C4 and C5 owners? Is there such a thing as normal battery life expectancy for a 96 (or other years for that matter)? All feedback appreciated as I'm kind of puzzled by this.:cool
