Battery low and will not start the car after 1 week

I have a 2003 ZO6 I just put my 2nd battery in and I still have to jump it with my jump box after 1 week. Lights are bright, I do not lose radio channels, but my HUD is not ware I left it and my clock is not the right time. What is going on?

May want to look at alternator and charging circuit. Was is the charging voltage during driving? It should be above 14V.

For storage over longer periods we recommend:
CTEK Multi US 3300 12-Volt Smart Battery Charger

This is the same charger GM licensed as a factory option on the C6 Corvette so you know its good!
