The new battery, Bosch 720 CCA, on my car goes flat if I don't drive for more than 2 days. It is in the shop now on it's 3rd. visit for this and I have told them to keep it until they figure it out. The battery, 2 weeks old, checks out as good. The alternator is charging at specs and the diode is also at specs. does anyone have any advice to offer on this?

There are threads that talk about possible battery drain. One possibility in seat adjusting button getting stuck.
Also, check the starter - I once had similar drain problems and in the end turned out the starter needed replacement.

If the battery is good and it is charging there must be a large, continuous load that is draining the battery. The obvious are lights including interior dome light.
