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?

Answer:
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!
