2011 G37. Battery dies if car left 7-10 days unused. Battery has checked out ok. Where to check net?
Thanks, Grampa Bill
How old is your battery?
Are all of the cells of your battery accepting a full charge?
Use a battery hydrometer to test them
Obtain a digital voltage monitor to monitor the output charging voltage of your alternator
