Battery issues
I have a 1997 corvette and the problem I am having is with my battery or so I think.
I put a new battery my vette back in june and everything was great until this wednesday I got my car but it was completely dead. i jumped the car and it started right up so I figured maybe I left the interior light on but there was nothing on. well i drove to work with no problems the car sat all day got in it to go home it started with no issues. I got up thursday dead again so I took the car to to pep boys just to have then check the battery and it seems everything is fine the is carrying 12.7 volts while running
Does anyone have an idea what could be causing the battery not to go dead every night
ps all battery connection are good

Fully charge your battery and then take it to AutoZone or Advance Auto and have the battery FULLY tested.
If its GOOD,,,reinstall it and torque the battery terminals to 11 ft/lbs for proper contact.
Start the engine. Measure the voltage at the BATTERY TERMINALS with a DC Volt Meter. You should see 14.5-15.5 VDC
On the back of the alternator, theres a Black boot covering the BATT terminal. With the engine running, it should read 14.5 - 15.5 VDC with the meter on the BATT terminal and Chassis GROUND.
If the voltages differ,,,,,,you have a problem with the wire from the alternator to the battery /starter
the voltage on the BATT terminal and the battery terminals

Did you ever check the battery voltage at the terminals without the car running to see if it was putting out at least 12 volts?
You may have a cell going bad or an internal problem with the battery.
