Right Battery Voltage?
Was wondering what your battery voltage reads when your car sits for a couple days at a time. I have a 4 month old red top in er, but have battery woes in my 01 Z06 for a couple years (on and off). When the car sits for a couple days and I put the key in the ignition, the battery voltage gage reads 11.3-11.6. When I crank it, it drops to 11.0-11.3 and then climbs over 12 and settles b/t 13.6 and 14.0 when driving. Is this normal. My car is not a daily driver and I just replaced my side mount screws for the battery cables to ensure they are tight like a tiger 
Any help would be appreciated

I'd suspect the battery before an excessive current draw. I had a basically new Optima go bad on me and it wouldn't hold a charge for more than a week without getting well below 12 volts. Lots of members have has Optimas Red Tops go south on them.

Could be bad battery also.
